Macular vasculopathy and its evolution in incontinentia pigmenti. (1/55)
PURPOSE: To describe macular vasculopathy in incontinentia pigmenti. METHODS: Twelve baby girls with incontinentia pigmenti were examined under general anesthesia by fluorescein angiography of the macula. Nine eyes of 9 patients had sufficient detail to allow evaluation of capillary changes. Angiography was initiated as early as 3 months of age and was repeated in 7 eyes at 3- to 12-month intervals. Changes in capillary patterns were identified. RESULTS: Irregularly enlarged or distorted foveal avascular zones were noted in all 9 maculas. Sparseness of the perifoveolar capillary bed was a characteristic finding. Sequential macular angiography demonstrated non-progressive (stable) capillary closure in 2 eyes; progressive closure in another macula; progressive closure plus addition or reopening of macular capillaries in 3 eyes; and central retinal artery occlusion, with cherry-red spot formation, in 1 eye at 12 days of age. In addition, progressive tractional detachment of the macula occurred in 2 of these eyes, and progressive macular neovascularization occurred in 1 eye. CONCLUSIONS: Macular ischemia is characteristic of incontinentia pigmenti and is often progressive. It is the initiating event of a typical vasculopathy, characterized by capillary remodelling and, occasionally, by neovascularization and tractional detachment of the retina. (+info)Rett syndrome and beyond: recurrent spontaneous and familial MECP2 mutations at CpG hotspots. (2/55)
Rett syndrome (RTT) is a neurodevelopmental disorder characterized by loss of acquired skills after a period of normal development in infant girls. The responsible gene, encoding methyl-CpG binding protein 2 (MeCP2), was recently discovered. Here we explore the spectrum of phenotypes resulting from MECP2 mutations. Both nonsense (R168X and R255X) and missense (R106W and R306C) mutations have been found, with multiple recurrences. R168X mutations were identified in six unrelated sporadic cases, as well as in two affected sisters and their normal mother. The missense mutations were de novo and affect conserved domains of MeCP2. All of the nucleotide substitutions involve C-->T transitions at CpG hotspots. A single nucleotide deletion, at codon 137, that creates a L138X stop codon within the methyl-binding domain was found in an individual with features of RTT and incontinentia pigmenti. An 806delG deletion causing a V288X stop in the transcription-repression domain was identified in a woman with motor-coordination problems, mild learning disability, and skewed X inactivation; in her sister and daughter, who were affected with classic RTT; and in her hemizygous son, who died from congenital encephalopathy. Thus, some males with RTT-causing MECP2 mutations may survive to birth, and female heterozygotes with favorably skewed X-inactivation patterns may have little or no involvement. Therefore, MECP2 mutations are not limited to RTT and may be implicated in a much broader phenotypic spectrum. (+info)Female mice heterozygous for IKK gamma/NEMO deficiencies develop a dermatopathy similar to the human X-linked disorder incontinentia pigmenti. (3/55)
IKK gamma/NEMO is the essential regulatory subunit of the I kappa B kinase (IKK), encoded by an X-linked gene in mice and humans. It is required for NF-kappa B activation and resistance to TNF-induced apoptosis. Female mice heterozygous for Ikk gamma/Nemo deficiency develop a unique dermatopathy characterized by keratinocyte hyperproliferation, skin inflammation, hyperkeratosis, and increased apoptosis. Although Ikk gamma+/- females eventually recover, Ikk gamma- males die in utero. These symptoms and inheritance pattern are very similar to those of incontinentia pigmenti (IP), a human genodermatosis, synthenic with the IKK gamma/NEMO locus. Indeed, biopsies and cells from IP patients exhibit defective IKK gamma/NEMO expression but normal expression of IKK catalytic subunits. This unique self-limiting disease, the first to be genetically linked to the IKK signaling pathway, is dependent on X-chromosome inactivation. We propose that the IKK gamma/NEMO-deficient cells trigger an inflammatory reaction that eventually leads to their death. (+info)NEMO/IKK gamma-deficient mice model incontinentia pigmenti. (4/55)
Disruption of the X-linked gene encoding NF-kappa B essential modulator (NEMO) produces male embryonic lethality, completely blocks NF-kappa B activation by proinflammatory cytokines, and interferes with the generation and/or persistence of lymphocytes. Heterozygous female mice develop patchy skin lesions with massive granulocyte infiltration and hyperproliferation and increased apoptosis of keratinocytes. Diseased animals present severe growth retardation and early mortality. Surviving mice recover almost completely, presumably through clearing the skin of NEMO-deficient keratinocytes. Male lethality and strikingly similar skin lesions in heterozygous females are hallmarks of the human genetic disorder incontinentia pigmenti (IP). Together with the recent discovery that mutations in the human NEMO gene cause IP, our results indicate that we have created a mouse model for that disease. (+info)A novel X-linked disorder of immune deficiency and hypohidrotic ectodermal dysplasia is allelic to incontinentia pigmenti and due to mutations in IKK-gamma (NEMO). (5/55)
Hypohidrotic ectodermal dysplasia (HED), a congenital disorder of teeth, hair, and eccrine sweat glands, is usually inherited as an X-linked recessive trait, although rarer autosomal dominant and recessive forms exist. We have studied males from four families with HED and immunodeficiency (HED-ID), in which the disorder segregates as an X-linked recessive trait. Affected males manifest dysgammaglobulinemia and, despite therapy, have significant morbidity and mortality from recurrent infections. Recently, mutations in IKK-gamma (NEMO) have been shown to cause familial incontinentia pigmenti (IP). Unlike HED-ID, IP affects females and, with few exceptions, causes male prenatal lethality. IKK-gamma is required for the activation of the transcription factor known as "nuclear factor kappa B" and plays an important role in T and B cell function. We hypothesize that "milder" mutations at this locus may cause HED-ID. In all four families, sequence analysis reveals exon 10 mutations affecting the carboxy-terminal end of the IKK-gamma protein, a domain believed to connect the IKK signalsome complex to upstream activators. The findings define a new X-linked recessive immunodeficiency syndrome, distinct from other types of HED and immunodeficiency syndromes. The data provide further evidence that the development of ectodermal appendages is mediated through a tumor necrosis factor/tumor necrosis factor receptor-like signaling pathway, with the IKK signalsome complex playing a significant role. (+info)A pregnancy following PGD for X-linked dominant [correction of X-linked autosomal dominant] incontinentia pigmenti (Bloch-Sulzberger syndrome): case report. (6/55)
Incontinentia Pigmenti (Bloch-Sulzberger syndrome) is a rare multisystem, ectodermal disorder associated with dermatological, dental and ocular features, and in <10% of cases, severe neurological deficit. Pedigree review suggests X-linked dominance with lethality in affected males. Presentation in female carriers is variable. Following genetic counselling, a mildly affected female carrier diagnosed in infancy with a de novo mutation was referred for preimplantation sexing, unusually selecting for male gender, with an acceptance of either normality or early miscarriage in an affected male. Following standard in-vitro fertilization and embryo biopsy, fluorescence in situ hybridization (FISH) unambiguously identified two male and two female embryos. A single 8-cell, grade 4 male embryo was replaced. A positive pregnancy test was reported 2 weeks after embryo transfer, although ultrasonography failed to demonstrate a viable pregnancy. Post abortive fetal tissue karyotyping diagnosed a male fetus with trisomy 16. This is an unusual report of preimplantation genetic diagnosis (PGD) being used for selection of males in an X-linked autosomal dominant disorder and demonstrates the value of PGD where amniocentesis or chorion villus sampling followed by abortion is not acceptable to the patient. This case also demonstrates the importance of follow-up prenatal diagnosis. (+info)Atypical forms of incontinentia pigmenti in male individuals result from mutations of a cytosine tract in exon 10 of NEMO (IKK-gamma). (7/55)
Familial incontinentia pigmenti (IP [MIM 308310]), or Bloch-Sulzberger syndrome, is an X-linked dominant and male-lethal disorder. We recently demonstrated that mutations in NEMO (IKK-gamma), which encodes a critical component of the NF-kappaB signaling pathway, were responsible for IP. Virtually all mutations eliminate the production of NEMO, causing the typical skewing of X inactivation in female individuals and lethality in male individuals, possibly through enhanced sensitivity to apoptosis. Most mutations also give rise to classic signs of IP, but, in this report, we describe two mutations in families with atypical phenotypes. Remarkably, each family included a male individual with unusual signs, including postnatal survival and either immune dysfunction or hematopoietic disturbance. We found two duplication mutations in these families, at a cytosine tract in exon 10 of NEMO, both of which remove the zinc (Zn) finger at the C-terminus of the protein. Two deletion mutations were also identified in the same tract in additional families. However, only the duplication mutations allowed male individuals to survive, and affected female individuals with duplication mutations demonstrated random or slight skewing of X inactivation. Similarly, NF-kappaB activation was diminished in the presence of duplication mutations and was completely absent in cells with deletion mutations. These results strongly indicate that male individuals can also suffer from IP caused by NEMO mutations, and we therefore urge a reevaluation of the diagnostic criteria. (+info)A recurrent deletion in the ubiquitously expressed NEMO (IKK-gamma) gene accounts for the vast majority of incontinentia pigmenti mutations. (8/55)
Incontinentia pigmenti (IP) is an X-linked dominant disorder characterized by abnormal skin pigmentation, retinal detachment, anodontia, alopecia, nail dystrophy and central nervous system defects. This disorder segregates as a male lethal disorder and causes skewed X-inactivation in female patients. IP is caused by mutations in a gene called NEMO, which encodes a regulatory component of the IkappaB kinase complex required to activate the NF-kappaB pathway. Here we report the identification of 277 mutations in 357 unrelated IP patients. An identical genomic deletion within NEMO accounted for 90% of the identified mutations. The remaining mutations were small duplications, substitutions and deletions. Nearly all NEMO mutations caused frameshift and premature protein truncation, which are predicted to eliminate NEMO function and cause cell lethality. Examination of families transmitting the recurrent deletion revealed that the rearrangement occurred in the paternal germline in most cases, indicating that it arises predominantly by intrachromosomal misalignment during meiosis. Expression analysis of human and mouse NEMO/Nemo showed that the gene becomes active early during embryogenesis and is expressed ubiquitously. These data confirm the involvement of NEMO in IP and will help elucidate the mechanism underlying the manifestation of this disorder and the in vivo function of NEMO. Based on these and other recent findings, we propose a model to explain the pathogenesis of this complex disorder. (+info)Incontinentia Pigmenti (IP) is a rare genetic disorder that primarily affects the skin, hair, and teeth. It is usually apparent at birth or in early infancy. The condition is characterized by four stages of skin changes:
1. Vesiculobullous stage: This stage appears shortly after birth and is characterized by blisters and inflammation on the skin.
2. Verrucous stage: In this stage, which occurs around 6 months of age, the blisters turn into wart-like growths.
3. Hyperpigmented stage: This stage appears between ages 1 to 6 years and is characterized by swirling patterns of darkened skin.
4. Hypopigmented stage: In this final stage, which occurs in adolescence or early adulthood, the skin becomes paler in areas where the hyperpigmentation occurred.
Incontinentia Pigmenti is caused by mutations in the IKBKG gene and is inherited in an X-linked dominant pattern, meaning that females are more likely to be affected than males. The condition can also affect other organs, including the eyes, nails, hair, teeth, and central nervous system. Treatment typically focuses on managing symptoms and preventing complications.
Pigmentation disorders are conditions that affect the production or distribution of melanin, the pigment responsible for the color of skin, hair, and eyes. These disorders can cause changes in the color of the skin, resulting in areas that are darker (hyperpigmentation) or lighter (hypopigmentation) than normal. Examples of pigmentation disorders include melasma, age spots, albinism, and vitiligo. The causes, symptoms, and treatments for these conditions can vary widely, so it is important to consult a healthcare provider for an accurate diagnosis and treatment plan.
A toe phalanx is a bone in the toe, specifically referring to one of the 14 small bones that make up the digits of the foot, excluding the sesamoid bones. Each toe has three phalanges, except for the big toe, which only has two. These bones help form the basic structure of the toes and allow for their movement and flexibility. The term "phalanx" comes from Greek, meaning "a row of soldiers standing together in close order," which is fitting given how these bones are arranged in a line within each toe.
Tooth abnormalities refer to any variations or irregularities in the size, shape, number, structure, or development of teeth that deviate from the typical or normal anatomy. These abnormalities can occur in primary (deciduous) or permanent teeth and can be caused by genetic factors, environmental influences, systemic diseases, or localized dental conditions during tooth formation.
Some examples of tooth abnormalities include:
1. Microdontia - teeth that are smaller than normal in size.
2. Macrodontia - teeth that are larger than normal in size.
3. Peg-shaped teeth - teeth with a narrow, conical shape.
4. Talon cusps - additional cusps or points on the biting surface of a tooth.
5. Dens invaginatus - an abnormal development where the tooth crown has an extra fold or pouch that can trap bacteria and cause dental problems.
6. Taurodontism - teeth with large pulp chambers and short roots.
7. Supernumerary teeth - having more teeth than the typical number (20 primary and 32 permanent teeth).
8. Hypodontia - missing one or more teeth due to a failure of development.
9. Germination - two adjacent teeth fused together, usually occurring in the front teeth.
10. Fusion - two separate teeth that have grown together during development.
Tooth abnormalities may not always require treatment unless they cause functional, aesthetic, or dental health issues. A dentist can diagnose and manage tooth abnormalities through various treatments, such as fillings, extractions, orthodontic care, or restorative procedures.
Genetic dosage compensation is a process that evens out the effects of genes on an organism's phenotype (observable traits), even when there are differences in the number of copies of those genes present. This is especially important in cases where sex chromosomes are involved, as males and females often have different numbers of sex chromosomes.
In many species, including humans, females have two X chromosomes, while males have one X and one Y chromosome. To compensate for the difference in dosage, one of the female's X chromosomes is randomly inactivated during early embryonic development, resulting in each cell having only one active X chromosome, regardless of sex. This process ensures that both males and females have similar levels of gene expression from their X chromosomes and helps to prevent an imbalance in gene dosage between the sexes.
Defects in dosage compensation can lead to various genetic disorders, such as Turner syndrome (where a female has only one X chromosome) or Klinefelter syndrome (where a male has two or more X chromosomes). These conditions can result in developmental abnormalities and health issues due to the imbalance in gene dosage.
I-kappa B kinase (IKK) is a protein complex that plays a crucial role in the activation of NF-kB (nuclear factor kappa-light-chain-enhancer of activated B cells), a transcription factor involved in the regulation of immune response, inflammation, cell survival, and proliferation.
The IKK complex is composed of two catalytic subunits, IKKα and IKKβ, and a regulatory subunit, IKKγ (also known as NEMO). Upon stimulation by various signals such as cytokines, pathogens, or stress, the IKK complex becomes activated and phosphorylates I-kappa B (IkB), an inhibitor protein that keeps NF-kB in an inactive state in the cytoplasm.
Once IkB is phosphorylated by the IKK complex, it undergoes ubiquitination and degradation, leading to the release and nuclear translocation of NF-kB, where it can bind to specific DNA sequences and regulate gene expression. Dysregulation of IKK activity has been implicated in various pathological conditions, including chronic inflammation, autoimmune diseases, and cancer.
The X chromosome is one of the two types of sex-determining chromosomes in humans (the other being the Y chromosome). It's one of the 23 pairs of chromosomes that make up a person's genetic material. Females typically have two copies of the X chromosome (XX), while males usually have one X and one Y chromosome (XY).
The X chromosome contains hundreds of genes that are responsible for the production of various proteins, many of which are essential for normal bodily functions. Some of the critical roles of the X chromosome include:
1. Sex Determination: The presence or absence of the Y chromosome determines whether an individual is male or female. If there is no Y chromosome, the individual will typically develop as a female.
2. Genetic Disorders: Since females have two copies of the X chromosome, they are less likely to be affected by X-linked genetic disorders than males. Males, having only one X chromosome, will express any recessive X-linked traits they inherit.
3. Dosage Compensation: To compensate for the difference in gene dosage between males and females, a process called X-inactivation occurs during female embryonic development. One of the two X chromosomes is randomly inactivated in each cell, resulting in a single functional copy per cell.
The X chromosome plays a crucial role in human genetics and development, contributing to various traits and characteristics, including sex determination and dosage compensation.
