A metabolic disease characterized by the defective transport of CYSTINE across the lysosomal membrane due to mutation of a membrane protein cystinosin. This results in cystine accumulation and crystallization in the cells causing widespread tissue damage. In the KIDNEY, nephropathic cystinosis is a common cause of RENAL FANCONI SYNDROME.
A hereditary or acquired form of generalized dysfunction of the PROXIMAL KIDNEY TUBULE without primary involvement of the KIDNEY GLOMERULUS. It is usually characterized by the tubular wasting of nutrients and salts (GLUCOSE; AMINO ACIDS; PHOSPHATES; and BICARBONATES) resulting in HYPOKALEMIA; ACIDOSIS; HYPERCALCIURIA; and PROTEINURIA.
A mercaptoethylamine compound that is endogenously derived from the COENZYME A degradative pathway. The fact that cysteamine is readily transported into LYSOSOMES where it reacts with CYSTINE to form cysteine-cysteamine disulfide and CYSTEINE has led to its use in CYSTINE DEPLETING AGENTS for the treatment of CYSTINOSIS.
Amino acid transporter systems capable of transporting neutral amino acids (AMINO ACIDS, NEUTRAL).
A covalently linked dimeric nonessential amino acid formed by the oxidation of CYSTEINE. Two molecules of cysteine are joined together by a disulfide bridge to form cystine.

Infantile cystinosis in France: genetics, incidence, geographic distribution. (1/130)

A national distribution of 66 French patients, from 49 sibships, has been studied. Segregation analysis, using the maximum likelihood method, was found to agree with the theoretical values expected in recessive autosomal inheritance. The birthplaces of these patients show an unequal geographic distribution of cystinosis, the incidence being higher in Western France. Compared with the total number of live births during the period 1959 to 1972, the minimum incidence of the condition in the province of Brittany is 1 per 25 909, and the gene frequency 0.0062. In the rest of France, the minimum incidence is 1 per 326,440 and the gene frequency 0.0018. Application of Dahlberg's formula gives a similar result. The mean inbreeding coefficient is 530 X 10(-5), a figure 23 times higher than the mean coefficient of France. An indirect test of inbreeding, the distance between parental birthplaces, was studied, first using the French administrative boundaries, second by using kilometers. This distance was constantly smaller for the parents of patients than for the parents of controls. Analysis of two erythrocyte polymorphisms (ABO and Rh) showed a large excess of group A patients when compared with overall French data. These findings are difficult to interpret on genetic grounds. The genetic reasons for the unequal geographic distribution of cystinosis in France are discussed.  (+info)

Molecular characterization of CTNS deletions in nephropathic cystinosis: development of a PCR-based detection assay. (2/130)

Nephropathic cystinosis is an autosomal recessive disorder that is characterized by accumulation of intralysosomal cystine and is caused by a defect in the transport of cystine across the lysosomal membrane. Using a positional cloning strategy, we recently cloned the causative gene, CTNS, and identified pathogenic mutations, including deletions, that span the cystinosis locus. Two types of deletions were detected-one of 9.5-16 kb, which was seen in a single family, and one of approximately 65 kb, which is the most frequent mutation found in the homozygous state in nearly one-third of cystinotic individuals. We present here characterization of the deletion breakpoints and demonstrate that, although both deletions occur in regions of repetitive sequences, they are the result of nonhomologous recombination. This type of mechanism suggests that the approximately 65-kb deletion is not a recurrent mutation, and our results confirm that it is identical in all patients. Haplotype analysis shows that this large deletion is due to a founder effect that occurred in a white individual and that probably arose in the middle of the first millenium. We also describe a rapid PCR-based assay that will accurately detect both homozygous and heterozygous deletions, and we use it to show that the approximately 65-kb deletion is present in either the homozygous or the heterozygous state in 76% of cystinotic patients of European origin.  (+info)

Molecular analysis of cystinosis: probable Irish origin of the most common French Canadian mutation. (3/130)

Infantile nephropathic cystinosis, an autosomal recessive disease characterized by a lysosomal accumulation of cystine, presents as failure to thrive, rickets and proximal renal tubular acidosis. The cystinosis gene, CTNS, which maps to chromosome 17p13, encodes a predicted 55 kDa protein with characteristics of a lysosomal membrane protein. We have conducted extensive linkage analysis in a French Canadian cystinosis cohort identifying a founding haplotype present in approximately half (21/40) of the chromosomes studied. Subsequent mutational analysis, in addition to identifying two novel mutations, has unexpectedly revealed a mutation which has been previously found in Irish (but not French) cystinotic families on these 21 French Canadian chromosomes. Haplotype analysis of two Irish families with this mutation supports the hypothesis that Celtic chromosomes represent an extensive portion of cystinosis chromosomes in French Canada. Our analysis underlines the genetic heterogeneity of the French Canadian population, reflecting a frequently unrecognized contribution from non-Gallic sources including the Irish.  (+info)

Severity of phenotype in cystinosis varies with mutations in the CTNS gene: predicted effect on the model of cystinosin. (4/130)

Infantile nephropathic cystinosis is a rare, autosomal recessive disease caused by a defect in the transport of cystine across the lysosomal membrane and characterized by early onset of renal proximal tubular dysfunction. Late-onset cystinosis, a rarer form of the disorder, is characterized by onset of symptoms between 12 and 15 years of age. We previously characterized the cystinosis gene, CTNS, and identified pathogenic mutations in patients with infantile nephropathic cystinosis, including a common, approximately 65 kb deletion which encompasses exons 1-10. Structure predictions suggested that the gene product, cystinosin, is a novel integral lysosomal membrane protein. We now examine the predicted effect of mutations on this model of cystinosin. In this study, we screened patients with infantile nephropathic cystinosis, those with late-onset cystinosis and patients whose phenotype does not fit the classical definitions. We found 23 different mutations in CTNS; 14 are novel mutations. Out of 25 patients with infantile nephropathic cystinosis, 12 have two severely truncating mutations, which is consistent with a loss of functional protein, and 13 have missense or in-frame deletions, which would result in disruption of transmembrane domains and loss of protein function. Mutations found in two late-onset patients affect functionally unimportant regions of cystinosin, which accounts for their milder phenotype. For three patients, the age of onset of cystinosis was <7 years but the course of the disease was milder than the infantile nephropathic form. This suggests that the missense mutations found in these individuals allow production of functional protein and may also indicate regions of cystinosin which are not functionally important.  (+info)

New method for determining cystine in leukocytes and fibroblasts. (5/130)

BACKGROUND: Cystinosis is a rare inborn error of cystine transport, leading to accumulation of cystine in the lysosomes. To diagnose cystinosis and monitor treatment with cysteamine, adequate measurements of cystine concentrations in leukocytes and cultured fibroblasts are required. METHODS: Cells were sonicated in the presence of excess N-ethylmaleimide to prevent oxidation of cysteine to cystine and disulfide exchange reactions of cystine with available sulfhydryl moieties. Cystine was measured as cysteine after reduction with sodium borohydride and derivatization with monobromobimane, followed by separation with automated HPLC and fluorescence detection. RESULTS: The assay was linear to 200 micromol/L cysteine. Within-run and day-to-day (total) imprecision (CV) was <5%, and the detection limit was 0.3 micromol/L. Added cysteine, up to 200 micromol/L, was completely removed, and recovery of added cystine was 69-86%. Cystine was stable for at least 2 months in leukocytes frozen in liquid nitrogen and stored at -80 degrees C CONCLUSIONS: Oxidation of cysteine to cystine and disulfide exchange reactions of cystine with sulfhydryl moieties are prevented by N-ethylmaleimide. The detection limit for the determination of cystine is adequate to measure cystine in leukocytes and cultured fibroblasts for diagnosis of cystinosis and monitoring treatment with cysteamine.  (+info)

The genomic region encompassing the nephropathic cystinosis gene (CTNS): complete sequencing of a 200-kb segment and discovery of a novel gene within the common cystinosis-causing deletion. (6/130)

Nephropathic cystinosis is an autosomal recessive disorder caused by the defective transport of cystine out of lysosomes. Recently, the causative gene (CTNS) was identified and presumed to encode an integral membrane protein called cystinosin. Many of the disease-associated mutations in CTNS are deletions, including one >55 kb in size that represents the most common cystinosis allele encountered to date. In an effort to determine the precise genomic organization of CTNS and to gain sequence-based insight about the DNA within and flanking cystinosis-associated deletions, we mapped and sequenced the region of human chromosome 17p13 encompassing CTNS. Specifically, a bacterial artificial chromosome (BAC)-based physical map spanning CTNS was constructed by sequence-tagged site (STS)-content mapping. The resulting BAC contig provided the relative order of 43 STSs. Two overlapping BACs, which together contain all of the CTNS exons as well as extensive amounts of flanking DNA, were selected and subjected to shotgun sequencing. A total of 200,237 bp of contiguous, high-accuracy sequence was generated. Analysis of the resulting data revealed a number of interesting features about this genomic region, including the long-range organization of CTNS, insight about the breakpoints and intervening DNA associated with the common cystinosis-causing deletion, and structural information about five genes neighboring CTNS (human ortholog of rat vanilloid receptor subtype 1 gene, CARKL, TIP-1, P2X5, and HUMINAE). In particular, sequence analysis detected the presence of a novel gene (CARKL) residing within the most common cystinosis-causing deletion. This gene encodes a previously unknown protein that is predicted to function as a carbohydrate kinase. Interestingly, both CTNS and CARKL are absent in nearly half of all cystinosis patients (i.e., those homozygous for the common deletion). [The sequence data described in this paper have been submitted to the GenBank data library under accession nos. AF168787 and AF163573.]  (+info)

The targeting of cystinosin to the lysosomal membrane requires a tyrosine-based signal and a novel sorting motif. (7/130)

Cystinosis is a lysosomal transport disorder characterized by an accumulation of intra-lysosomal cystine. Biochemical studies showed that the lysosomal cystine transporter was distinct from the plasma membrane cystine transporters and that it exclusively transported cystine. The gene underlying cystinosis, CTNS, encodes a predicted seven-transmembrane domain protein called cystinosin, which is highly glycosylated at the N-terminal end and carries a GY-XX-Phi (where Phi is a hydrophobic residue) lysosomal-targeting motif in its carboxyl tail. We constructed cystinosin-green fluorescent protein fusion proteins to determine the subcellular localization of cystinosin in transfected cell lines and showed that cystinosin-green fluorescent protein colocalizes with lysosomal-associated membrane protein 2 (LAMP-2) to lysosomes. Deletion of the GY-XX-Phi motif resulted in a partial redirection to the plasma membrane as well as sorting to lysosomes, demonstrating that this motif is only partially responsible for the lysosomal targeting of cystinosin and suggesting the existence of a second sorting signal. A complete relocalization of cystinosin to the plasma membrane was obtained after deletion of half of the third cytoplasmic loop (amino acids 280-288) coupled with the deletion of the GY-DQ-L motif, demonstrating the presence of the second signal within this loop. Using site-directed mutagenesis studies we identified a novel conformational lysosomal-sorting motif, the core of which was delineated to YFPQA (amino acids 281-285).  (+info)

The promoter of a lysosomal membrane transporter gene, CTNS, binds Sp-1, shares sequences with the promoter of an adjacent gene, CARKL, and causes cystinosis if mutated in a critical region. (8/130)

Although >55 CTNS mutations occur in patients with the lysosomal storage disorder cystinosis, no regulatory mutations have been reported, because the promoter has not been defined. Using CAT reporter constructs of sequences 5' to the CTNS coding sequence, we identified the CTNS promoter as the region encompassing nucleotides -316 to +1 with respect to the transcription start site. This region contains an Sp-1 regulatory element (GGCGGCG) at positions -299 to -293, which binds authentic Sp-1, as shown by electrophoretic-mobility-shift assays. Three patients exhibited mutations in the CTNS promoter. One patient with nephropathic cystinosis carried a -295 G-->C substitution disrupting the Sp-1 motif, whereas two patients with ocular cystinosis displayed a -303 G-->T substitution in one case and a -303 T insertion in the other case. Each mutation drastically reduced CAT activity when inserted into a reporter construct. Moreover, each failed either to cause a mobility shift when exposed to nuclear extract or to compete with the normal oligonucleotide's mobility shift. The CTNS promoter region shares 41 nucleotides with the promoter region of an adjacent gene of unknown function, CARKL, whose start site is 501 bp from the CTNS start site. However, the patients' CTNS promoter mutations have no effect on CARKL promoter activity. These findings suggest that the CTNS promoter region should be examined in patients with cystinosis who have fewer than two coding-sequence mutations.  (+info)

Cystinosis is a rare, inherited metabolic disorder that affects primarily the eyes, kidneys, and liver. It is characterized by an abnormal accumulation of the amino acid cystine within lysosomes (cellular organelles responsible for breaking down and recycling waste products) due to a defect in the gene CTNS that encodes for a protein called cystinosin. This leads to the formation of crystals, which can cause cell damage and multi-organ dysfunction.

There are three main types of cystinosis:

1. Nephropathic or infantile cystinosis: This is the most severe form, with symptoms appearing within the first year of life. It primarily affects the kidneys, leading to Fanconi syndrome (a condition characterized by excessive loss of nutrients in urine), growth failure, and kidney dysfunction. If left untreated, it can progress to end-stage renal disease (ESRD) around the age of 10.
2. Intermediate cystinosis: This form presents during childhood with milder kidney involvement but can still lead to ESRD in adolescence or early adulthood. Eye and central nervous system abnormalities may also be present.
3. Non-nephropathic or ocular cystinosis: This is the mildest form, primarily affecting the eyes. Symptoms include photophobia (sensitivity to light), corneal opacities, and decreased vision. Kidney function remains normal in this type.

Treatment for cystinosis typically involves a combination of medications to manage symptoms and slow disease progression. Cysteamine therapy, which helps remove excess cystine from cells, is the primary treatment for all types of cystinosis. Regular monitoring and management of complications are essential to maintain quality of life and prolong survival.

Fanconi syndrome is a medical condition that affects the proximal tubules of the kidneys. These tubules are responsible for reabsorbing various substances, such as glucose, amino acids, and electrolytes, back into the bloodstream after they have been filtered through the kidneys.

In Fanconi syndrome, there is a defect in the reabsorption process, causing these substances to be lost in the urine instead. This can lead to a variety of symptoms, including:

* Polyuria (excessive urination)
* Polydipsia (excessive thirst)
* Dehydration
* Metabolic acidosis (an imbalance of acid and base in the body)
* Hypokalemia (low potassium levels)
* Hypophosphatemia (low phosphate levels)
* Vitamin D deficiency
* Rickets (softening and weakening of bones in children) or osteomalacia (softening of bones in adults)

Fanconi syndrome can be caused by a variety of underlying conditions, including genetic disorders, kidney diseases, drug toxicity, and heavy metal poisoning. Treatment typically involves addressing the underlying cause, as well as managing symptoms such as electrolyte imbalances and acid-base disturbances.

Cysteamine is a medication and a naturally occurring aminothiol compound, which is composed of the amino acid cysteine and a sulfhydryl group. It has various uses in medicine, including as a treatment for cystinosis, a rare genetic disorder that causes an accumulation of cystine crystals in various organs and tissues. Cysteamine works by reacting with cystine to form a compound that can be more easily eliminated from the body. It is available in oral and topical forms and may also be used for other indications, such as treating lung diseases and radiation-induced damage.

Neutral amino acid transport systems refer to a group of membrane transporters that facilitate the movement of neutral amino acids across cell membranes. Neutral amino acids are those that have a neutral charge at physiological pH and include amino acids such as alanine, serine, threonine, valine, leucine, isoleucine, methionine, cysteine, tyrosine, phenylalanine, and tryptophan.

There are several different transport systems that have been identified for neutral amino acids, each with its own specificity and affinity for different amino acids. Some of the major neutral amino acid transport systems include:

1. System A: This transporter preferentially transports small, neutral amino acids such as alanine, serine, and threonine. It is found in many tissues, including the intestines, kidneys, and brain.
2. System B0+: This transporter preferentially transports large, neutral amino acids such as leucine, isoleucine, valine, methionine, and phenylalanine. It is found in many tissues, including the intestines, kidneys, and brain.
3. System L: This transporter preferentially transports large, neutral amino acids such as leucine, isoleucine, valine, methionine, and phenylalanine. It is found in many tissues, including the intestines, kidneys, and brain.
4. System y+: This transporter preferentially transports cationic amino acids such as lysine and arginine, but it can also transport some neutral amino acids. It is found in many tissues, including the intestines, kidneys, and brain.
5. System b0,+: This transporter preferentially transports cationic amino acids such as lysine and arginine, but it can also transport some neutral amino acids. It is found in many tissues, including the intestines, kidneys, and brain.

These transport systems play important roles in maintaining amino acid homeostasis in the body, as well as in various physiological processes such as protein synthesis, neurotransmitter synthesis, and cell signaling. Dysregulation of these transport systems has been implicated in several diseases, including cancer, neurological disorders, and metabolic disorders.

Cystine is a naturally occurring amino acid in the body, which is formed from the oxidation of two cysteine molecules. It is a non-essential amino acid, meaning that it can be produced by the body and does not need to be obtained through diet. Cystine plays important roles in various biological processes, including protein structure and antioxidant defense. However, when cystine accumulates in large amounts, it can form crystals or stones, leading to conditions such as cystinuria, a genetic disorder characterized by the formation of cystine kidney stones.

Polydipsia is a medical term that describes excessive thirst or an abnormally increased desire to drink fluids. It is often associated with conditions that cause increased fluid loss, such as diabetes insipidus and diabetes mellitus, as well as certain psychiatric disorders that can lead to excessive water intake. Polydipsia should not be confused with simple dehydration, where the body's overall water content is reduced due to inadequate fluid intake or excessive fluid loss. Instead, polydipsia refers to a persistent and strong drive to drink fluids, even when the body is adequately hydrated. Prolonged polydipsia can lead to complications such as hyponatremia (low sodium levels in the blood) and may indicate an underlying medical issue that requires further evaluation and treatment.

The term "nervous system physiological processes" refers to the various functional activities and mechanisms that occur within the nervous system, which is responsible for controlling and coordinating bodily functions. These processes include:

1. Electrical impulse transmission: The nervous system transmits electrical signals called action potentials through neurons to transmit information between different parts of the body.
2. Neurotransmitter release and reception: Neurons communicate with each other and with other cells by releasing neurotransmitters, which are chemical messengers that bind to receptors on target cells.
3. Sensory perception: Specialized sensory neurons detect changes in the external environment (e.g., light, sound, temperature, touch) or internal environment (e.g., blood pressure, pH, glucose levels) and transmit this information to the brain for processing.
4. Motor control: The nervous system controls voluntary and involuntary movements by sending signals from the brain to muscles and glands.
5. Homeostasis: The nervous system helps maintain internal homeostasis by regulating vital functions such as heart rate, respiratory rate, body temperature, and fluid balance.
6. Cognition: The nervous system is involved in higher cognitive functions such as learning, memory, attention, perception, and language.
7. Emotional regulation: The nervous system plays a crucial role in emotional processing and regulation through its connections with the limbic system and hypothalamus.
8. Sleep-wake cycle: The nervous system regulates the sleep-wake cycle through the interaction of various neurotransmitters and brain regions.

These physiological processes are essential for normal bodily function and are tightly regulated to ensure optimal performance. Dysfunction in any aspect of the nervous system can lead to a wide range of neurological and psychiatric disorders.

Benign migratory glossitis, also known as geographic tongue, is a medical condition characterized by the presence of denuded, irregularly shaped smooth patches on the dorsum of the tongue. These patches are usually red and often have a white or yellow border. The condition is called "benign migratory" because it is not harmful or cancerous, and the lesions can change in size, shape, and location over time.

The exact cause of benign migratory glossitis is unknown, but it has been associated with several factors such as stress, nutritional deficiencies (particularly vitamin B deficiency), allergies, and family history. The condition can be asymptomatic or may cause symptoms such as burning sensation, pain, or altered taste.

Treatment of benign migratory glossitis is usually not necessary unless the patient experiences discomfort or other symptoms. In such cases, topical anesthetics, antihistamines, or corticosteroids may be prescribed to alleviate the symptoms. However, if the underlying cause can be identified and addressed (such as nutritional deficiencies), the condition may improve on its own.

I am not aware of a medical term called "Cystaphos." It is possible that there may be a typographical error or misspelling in the term. If you have more context about where this term was used, I may be able to provide more information. However, without further information, I cannot provide a medical definition for "Cystaphos."

"Age determination by teeth" is a method used in forensic dentistry to estimate the age of an individual based on the development and wear of their teeth. This process involves examining various features such as tooth eruption, crown and root formation, and dental attrition or wear.

The developmental stages of teeth can provide a rough estimate of age during childhood and adolescence, while dental wear patterns can offer insights into an individual's age during adulthood. However, it is important to note that there can be significant variation in tooth development and wear between individuals, making this method somewhat imprecise.

In addition to forensic applications, age determination by teeth can also be useful in archaeology and anthropology for studying past populations and their lifestyles.

An encyclopedia is a comprehensive reference work containing articles on various topics, usually arranged in alphabetical order. In the context of medicine, a medical encyclopedia is a collection of articles that provide information about a wide range of medical topics, including diseases and conditions, treatments, tests, procedures, and anatomy and physiology. Medical encyclopedias may be published in print or electronic formats and are often used as a starting point for researching medical topics. They can provide reliable and accurate information on medical subjects, making them useful resources for healthcare professionals, students, and patients alike. Some well-known examples of medical encyclopedias include the Merck Manual and the Stedman's Medical Dictionary.

Lysosomal storage diseases (LSDs) are a group of rare inherited metabolic disorders caused by defects in lysosomal function. Lysosomes are membrane-bound organelles within cells that contain enzymes responsible for breaking down and recycling various biomolecules, such as proteins, lipids, and carbohydrates. In LSDs, the absence or deficiency of specific lysosomal enzymes leads to the accumulation of undigested substrates within the lysosomes, resulting in cellular dysfunction and organ damage.

These disorders can affect various organs and systems in the body, including the brain, nervous system, bones, skin, and visceral organs. Symptoms may include developmental delays, neurological impairment, motor dysfunction, bone abnormalities, coarse facial features, hepatosplenomegaly (enlarged liver and spleen), and recurrent infections.

Examples of LSDs include Gaucher disease, Tay-Sachs disease, Niemann-Pick disease, Fabry disease, Pompe disease, and mucopolysaccharidoses (MPS). Treatment options for LSDs may include enzyme replacement therapy, substrate reduction therapy, or bone marrow transplantation. Early diagnosis and intervention can help improve the prognosis and quality of life for affected individuals.
