(+info)Camptomelia in a rhesus macaque (Macaca mulatta). (2/11)
An 8.5-mo-old female rhesus macaque was examined for an apparent lump on the right arm, below the elbow. The macaque showed no signs of pain or discomfort. Examination revealed that the lump was actually a bend in the forearm. Radiography demonstrated that some of the long bones of the animal were bowed. Differential diagnoses included rickets, hyperparathyroidism, pseudohyperparathyroidism, and a growth dysplasia. No other similar abnormalities in animals from that cage or any other enclosure in our large colony were observed. Blood chemistries and a complete hemogram were within normal limits for a macaque of this age. Serum was submitted for a vitamin D profile that included assays for parathyroid hormone, 25-hydroxyvitamin D, and ionized calcium. Serum samples from sex- and age-matched normal controls were sent for comparison and to establish a baseline profile. The affected animal had vitamin D levels comparable to unaffected controls. Bone biopsies appeared normal for a macaque of this age. Fluorine levels in the drinking water supply were within acceptable limits. Consistent with the information available, a diagnosis of idiopathic camptomelia, or bowing of the long bones, was made. In humans, developmental camptomelia is associated with several bone dysplasias in infants and children. These conditions are thought to be caused by genetic mutations in enzymes or transcription factors that control development of the epiphyses and are almost always associated with other lethal and nonlethal developmental abnormalities.

(+info)Campomelic dysplasia is a rare genetic disorder that affects the development of bones and cartilage. The term "campomelic" comes from Greek words meaning "bent limb." The main feature of this condition is bowing of the legs, which occurs because of abnormal development of the bones in the legs before birth.
Campomelic dysplasia is caused by mutations in the SOX9 gene, which provides instructions for making a protein that is essential for normal development of the skeleton and reproductive system. This condition is often lethal in newborns, and those who survive may have other symptoms such as:
* Abnormalities of the face, including a small nose, cleft palate, and low-set ears
* Respiratory problems due to narrowed airways or underdeveloped lungs
* Abnormalities of the fingers and toes, such as webbing or fusion
* Genital abnormalities, particularly in males
* Hearing loss
* Intellectual disability
Campomelic dysplasia is typically inherited in an autosomal dominant manner, which means that a child can inherit the condition even if only one parent carries the mutated gene. However, most cases of campomelic dysplasia occur spontaneously due to new mutations in the SOX9 gene.
SOX9 (SRY-related HMG-box gene 9) is a transcription factor that belongs to the SOX family of proteins, which are characterized by a high mobility group (HMG) box DNA-binding domain. SOX9 plays crucial roles in various developmental processes, including sex determination, chondrogenesis, and neurogenesis.
As a transcription factor, SOX9 binds to specific DNA sequences in the promoter or enhancer regions of its target genes and regulates their expression. In the context of sex determination, SOX9 is essential for the development of Sertoli cells in the male gonad, which are responsible for supporting sperm production. SOX9 also plays a role in maintaining the undifferentiated state of stem cells and promoting cell differentiation in various tissues.
Mutations in the SOX9 gene have been associated with several human genetic disorders, including campomelic dysplasia, a severe skeletal disorder characterized by bowed legs, and sex reversal in individuals with XY chromosomes.
Osteochondrodysplasias are a group of genetic disorders that affect the development of bones and cartilage. These conditions can result in dwarfism or short stature, as well as other skeletal abnormalities. Osteochondrodysplasias can be caused by mutations in genes that regulate bone and cartilage growth, and they are often characterized by abnormalities in the shape, size, and/or structure of the bones and cartilage.
There are many different types of osteochondrodysplasias, each with its own specific symptoms and patterns of inheritance. Some common examples include achondroplasia, thanatophoric dysplasia, and spondyloepiphyseal dysplasia. These conditions can vary in severity, and some may be associated with other health problems, such as respiratory difficulties or neurological issues.
Treatment for osteochondrodysplasias typically focuses on managing the symptoms and addressing any related health concerns. This may involve physical therapy, bracing or surgery to correct skeletal abnormalities, and treatment for any associated medical conditions. In some cases, genetic counseling may also be recommended for individuals with osteochondrodysplasias and their families.
Developmental bone diseases are a group of medical conditions that affect the growth and development of bones. These diseases are present at birth or develop during childhood and adolescence, when bones are growing rapidly. They can result from genetic mutations, hormonal imbalances, or environmental factors such as poor nutrition.
Some examples of developmental bone diseases include:
1. Osteogenesis imperfecta (OI): Also known as brittle bone disease, OI is a genetic disorder that affects the body's production of collagen, a protein necessary for healthy bones. People with OI have fragile bones that break easily and may also experience other symptoms such as blue sclerae (whites of the eyes), hearing loss, and joint laxity.
2. Achondroplasia: This is the most common form of dwarfism, caused by a genetic mutation that affects bone growth. People with achondroplasia have short limbs and a large head relative to their body size.
3. Rickets: A condition caused by vitamin D deficiency or an inability to absorb or use vitamin D properly. This leads to weak, soft bones that can bow or bend easily, particularly in children.
4. Fibrous dysplasia: A rare bone disorder where normal bone is replaced with fibrous tissue, leading to weakened bones and deformities.
5. Scoliosis: An abnormal curvature of the spine that can develop during childhood or adolescence. While not strictly a developmental bone disease, scoliosis can be caused by various underlying conditions such as cerebral palsy, muscular dystrophy, or spina bifida.
Treatment for developmental bone diseases varies depending on the specific condition and its severity. Treatment may include medication, physical therapy, bracing, or surgery to correct deformities and improve function. Regular follow-up with a healthcare provider is essential to monitor growth, manage symptoms, and prevent complications.
High mobility group proteins (HMG proteins) are a family of nuclear proteins that are characterized by their ability to bind to DNA and influence its structure and function. They are named "high mobility" because of their rapid movement in gel electrophoresis. HMG proteins are involved in various nuclear processes, including chromatin remodeling, transcription regulation, and DNA repair.
There are three main classes of HMG proteins: HMGA, HMGB, and HMGN. Each class has distinct structural features and functions. For example, HMGA proteins have a unique "AT-hook" domain that allows them to bind to the minor groove of AT-rich DNA sequences, while HMGB proteins have two "HMG-box" domains that enable them to bend and unwind DNA.
HMG proteins play important roles in many physiological and pathological processes, such as embryonic development, inflammation, and cancer. Dysregulation of HMG protein function has been implicated in various diseases, including neurodegenerative disorders, diabetes, and cancer. Therefore, understanding the structure, function, and regulation of HMG proteins is crucial for developing new therapeutic strategies for these diseases.
Disorders of Sex Development (DSD) are a group of conditions that occur when there is a difference in the development and assignment of sex characteristics. These differences may be apparent at birth, at puberty, or later in life. DSD can affect chromosomes, gonads, genitals, or secondary sexual characteristics, and can result from genetic mutations or environmental factors during fetal development.
DSDs were previously referred to as "intersex" conditions, but the term "Disorders of Sex Development" is now preferred in medical settings because it is more descriptive and less stigmatizing. DSDs are not errors or abnormalities, but rather variations in human development that require sensitive and individualized care.
The diagnosis and management of DSD can be complex and may involve a team of healthcare providers, including endocrinologists, urologists, gynecologists, psychologists, and genetic counselors. Treatment options depend on the specific type of DSD and may include hormone therapy, surgery, or other interventions to support physical and emotional well-being.
Gonadal dysgenesis, 46,XY is a medical condition where the gonads (testes) fail to develop or function properly in an individual with a 46,XY karyotype (a normal male chromosomal composition). This means that the person has one X and one Y chromosome, but their gonads do not develop into fully functional testes. As a result, the person may have ambiguous genitalia or female external genitalia, and they will typically not produce enough or any male hormones. The condition can also be associated with an increased risk of developing germ cell tumors in the dysgenetic gonads.
The severity of gonadal dysgenesis, 46,XY can vary widely, and it may be accompanied by other developmental abnormalities or syndromes. Treatment typically involves surgical removal of the dysgenetic gonads to reduce the risk of tumor development, as well as hormone replacement therapy to support normal sexual development and reproductive function. The underlying cause of gonadal dysgenesis, 46,XY is not always known, but it can be associated with genetic mutations or chromosomal abnormalities.
Human chromosome pair 17 consists of two rod-shaped structures present in the nucleus of each human cell. Each chromosome is made up of DNA tightly coiled around histone proteins, forming a complex called chromatin. Chromosomes carry genetic information in the form of genes, which are segments of DNA that contain instructions for the development and function of an organism.
Human cells typically have 23 pairs of chromosomes, for a total of 46 chromosomes. Pair 17 is one of the autosomal pairs, meaning it is not a sex chromosome (X or Y). Chromosome 17 is a medium-sized chromosome and contains an estimated 800 million base pairs of DNA. It contains approximately 1,500 genes that provide instructions for making proteins and regulating various cellular processes.
Chromosome 17 is associated with several genetic disorders, including inherited cancer syndromes such as Li-Fraumeni syndrome and hereditary nonpolyposis colorectal cancer (HNPCC). Mutations in genes located on chromosome 17 can increase the risk of developing various types of cancer, including breast, ovarian, colon, and pancreatic cancer.
'Abnormalities, Multiple' is a broad term that refers to the presence of two or more structural or functional anomalies in an individual. These abnormalities can be present at birth (congenital) or can develop later in life (acquired). They can affect various organs and systems of the body and can vary greatly in severity and impact on a person's health and well-being.
Multiple abnormalities can occur due to genetic factors, environmental influences, or a combination of both. Chromosomal abnormalities, gene mutations, exposure to teratogens (substances that cause birth defects), and maternal infections during pregnancy are some of the common causes of multiple congenital abnormalities.
Examples of multiple congenital abnormalities include Down syndrome, Turner syndrome, and VATER/VACTERL association. Acquired multiple abnormalities can result from conditions such as trauma, infection, degenerative diseases, or cancer.
The medical evaluation and management of individuals with multiple abnormalities depend on the specific abnormalities present and their impact on the individual's health and functioning. A multidisciplinary team of healthcare professionals is often involved in the care of these individuals to address their complex needs.
Translocation, genetic, refers to a type of chromosomal abnormality in which a segment of a chromosome is transferred from one chromosome to another, resulting in an altered genome. This can occur between two non-homologous chromosomes (non-reciprocal translocation) or between two homologous chromosomes (reciprocal translocation). Genetic translocations can lead to various clinical consequences, depending on the genes involved and the location of the translocation. Some translocations may result in no apparent effects, while others can cause developmental abnormalities, cancer, or other genetic disorders. In some cases, translocations can also increase the risk of having offspring with genetic conditions.
Transcription factors are proteins that play a crucial role in regulating gene expression by controlling the transcription of DNA to messenger RNA (mRNA). They function by binding to specific DNA sequences, known as response elements, located in the promoter region or enhancer regions of target genes. This binding can either activate or repress the initiation of transcription, depending on the properties and interactions of the particular transcription factor. Transcription factors often act as part of a complex network of regulatory proteins that determine the precise spatiotemporal patterns of gene expression during development, differentiation, and homeostasis in an organism.
Fibrous Dysplasia of Bone is a rare, benign bone disorder that is characterized by the replacement of normal bone tissue with fibrous (scar-like) and immature bone tissue. This results in weakened bones that are prone to fractures, deformities, and pain. The condition can affect any bone in the body but most commonly involves the long bones of the legs, arms, and skull. It can occur as an isolated finding or as part of a genetic disorder called McCune-Albright syndrome. The exact cause of fibrous dysplasia is not fully understood, but it is believed to result from a genetic mutation that occurs during early bone development. There is no cure for fibrous dysplasia, and treatment typically focuses on managing symptoms and preventing complications.
A newborn infant is a baby who is within the first 28 days of life. This period is also referred to as the neonatal period. Newborns require specialized care and attention due to their immature bodily systems and increased vulnerability to various health issues. They are closely monitored for signs of well-being, growth, and development during this critical time.
Ectodermal dysplasia (ED) is a group of genetic disorders that affect the development and formation of ectodermal tissues, which include the skin, hair, nails, teeth, and sweat glands. The condition is usually present at birth or appears in early infancy.
The symptoms of ED can vary widely depending on the specific type and severity of the disorder. Common features may include:
* Sparse or absent hair
* Thin, wrinkled, or rough skin
* Abnormal or missing teeth
* Nail abnormalities
* Absent or reduced sweat glands, leading to heat intolerance and problems regulating body temperature
* Ear abnormalities, which can result in hearing loss
* Eye abnormalities
ED is caused by mutations in genes that are involved in the development of ectodermal tissues. Most cases of ED are inherited in an autosomal dominant or autosomal recessive pattern, meaning that a child can inherit the disorder even if only one parent (dominant) or both parents (recessive) carry the mutated gene.
There is no cure for ED, but treatment is focused on managing the symptoms and improving quality of life. This may include measures to maintain body temperature, such as cooling vests or frequent cool baths; dental treatments to replace missing teeth; hearing aids for hearing loss; and skin care regimens to prevent dryness and irritation.
Bronchopulmonary dysplasia (BPD) is a chronic lung disease that primarily affects premature infants. It is defined as the need for supplemental oxygen at 28 days of life or beyond, due to abnormal development and injury to the lungs.
The condition was first described in the 1960s, following the introduction of mechanical ventilation and high concentrations of oxygen therapy for premature infants with respiratory distress syndrome (RDS). These treatments, while lifesaving, can also cause damage to the delicate lung tissue, leading to BPD.
The pathogenesis of BPD is complex and involves an interplay between genetic factors, prenatal exposures, and postnatal injury from mechanical ventilation and oxygen toxicity. Inflammation, oxidative stress, and impaired lung development contribute to the development of BPD.
Infants with BPD typically have abnormalities in their airways, alveoli (air sacs), and blood vessels in the lungs. These changes can lead to symptoms such as difficulty breathing, wheezing, coughing, and poor growth. Treatment may include oxygen therapy, bronchodilators, corticosteroids, diuretics, and other medications to support lung function and minimize complications.
The prognosis for infants with BPD varies depending on the severity of the disease and associated medical conditions. While some infants recover completely, others may have long-term respiratory problems that require ongoing management.
Molecular sequence data refers to the specific arrangement of molecules, most commonly nucleotides in DNA or RNA, or amino acids in proteins, that make up a biological macromolecule. This data is generated through laboratory techniques such as sequencing, and provides information about the exact order of the constituent molecules. This data is crucial in various fields of biology, including genetics, evolution, and molecular biology, allowing for comparisons between different organisms, identification of genetic variations, and studies of gene function and regulation.
Dwarfism is a medical condition that is characterized by short stature, typically with an adult height of 4 feet 10 inches (147 centimeters) or less. It is caused by a variety of genetic and medical conditions that affect bone growth, including skeletal dysplasias, hormonal deficiencies, and chromosomal abnormalities.
Skeletal dysplasias are the most common cause of dwarfism and are characterized by abnormalities in the development and growth of bones and cartilage. Achondroplasia is the most common form of skeletal dysplasia, accounting for about 70% of all cases of dwarfism. It is caused by a mutation in the fibroblast growth factor receptor 3 (FGFR3) gene and results in short limbs, a large head, and a prominent forehead.
Hormonal deficiencies, such as growth hormone deficiency or hypothyroidism, can also cause dwarfism if they are not diagnosed and treated early. Chromosomal abnormalities, such as Turner syndrome (monosomy X) or Down syndrome (trisomy 21), can also result in short stature and other features of dwarfism.
It is important to note that people with dwarfism are not "dwarves" - the term "dwarf" is a medical and sociological term used to describe individuals with this condition, while "dwarves" is a term often used in fantasy literature and media to refer to mythical beings. The use of the term "dwarf" can be considered disrespectful or offensive to some people with dwarfism, so it is important to use respectful language when referring to individuals with this condition.
Musculoskeletal abnormalities refer to structural and functional disorders that affect the musculoskeletal system, which includes the bones, muscles, cartilages, tendons, ligaments, joints, and other related tissues. These abnormalities can result from genetic factors, trauma, overuse, degenerative processes, infections, or tumors. They may cause pain, stiffness, limited mobility, deformity, weakness, and susceptibility to injuries. Examples of musculoskeletal abnormalities include osteoarthritis, rheumatoid arthritis, scoliosis, kyphosis, lordosis, fractures, dislocations, tendinitis, bursitis, myopathies, and various congenital conditions.
Achondroplasia is a genetic disorder that affects bone growth, leading to dwarfism. It is the most common form of short-limbed dwarfism and is caused by a mutation in the FGFR3 gene. This mutation results in impaired endochondral ossification, which is the process by which cartilage is converted into bone.
People with achondroplasia have a characteristic appearance, including:
* Short stature (typically less than 4 feet, 4 inches tall)
* Disproportionately short arms and legs
* Large head with a prominent forehead and flat nasal bridge
* Short fingers with a gap between the middle and ring fingers (known as a trident hand)
* Bowing of the lower legs
* A swayed back (lordosis)
Achondroplasia is usually inherited in an autosomal dominant manner, which means that a child has a 50% chance of inheriting the disorder if one parent has it. However, about 80% of cases result from new mutations in the FGFR3 gene and occur in people with no family history of the condition.
While achondroplasia can cause various medical issues, such as breathing difficulties, ear infections, and spinal cord compression, most individuals with this condition have normal intelligence and a typical lifespan. Treatment typically focuses on managing specific symptoms and addressing any related complications.
Thnanatophoric Dysplasia is a severe skeletal disorder characterized by extreme short limbs, a narrow chest, and large head. It is one of the most common types of short-limbed dwarfism. The name "thanatophoric" comes from the Greek word thanatos, meaning death, as this condition is often lethal in the newborn period or shortly thereafter due to respiratory distress.
The disorder is caused by mutations in the FGFR3 gene, which provides instructions for making a protein that is part of a group of proteins called fibroblast growth factor receptors. These receptors play critical roles in many important processes during embryonic development, such as controlling bone growth.
There are two major types of thanatophoric dysplasia: type I and type II. Type I is characterized by curved thigh bones (femurs) and a clover-leaf shaped skull. Type II is characterized by straight femurs and an unossified (not fully developed) vertebral column.
The diagnosis of thanatophoric dysplasia can be made prenatally through ultrasound examination or postnatally through physical examination, X-rays, and genetic testing. Unfortunately, due to the severity of the condition, there is no cure for thanatophoric dysplasia and management is supportive in nature, focusing on providing comfort and addressing any complications that may arise.
Growth disorders are medical conditions that affect a person's growth and development, leading to shorter or taller stature than expected for their age, sex, and ethnic group. These disorders can be caused by various factors, including genetic abnormalities, hormonal imbalances, chronic illnesses, malnutrition, and psychosocial issues.
There are two main types of growth disorders:
1. Short stature: This refers to a height that is significantly below average for a person's age, sex, and ethnic group. Short stature can be caused by various factors, including genetic conditions such as Turner syndrome or dwarfism, hormonal deficiencies, chronic illnesses, malnutrition, and psychosocial issues.
2. Tall stature: This refers to a height that is significantly above average for a person's age, sex, and ethnic group. Tall stature can be caused by various factors, including genetic conditions such as Marfan syndrome or Klinefelter syndrome, hormonal imbalances, and certain medical conditions like acromegaly.
Growth disorders can have significant impacts on a person's physical, emotional, and social well-being. Therefore, it is essential to diagnose and manage these conditions early to optimize growth and development and improve overall quality of life. Treatment options for growth disorders may include medication, nutrition therapy, surgery, or a combination of these approaches.
