Summaries for Ichthyosis, X-Linked

OMIM : 53 X-linked ichthyosis is clinically characterized by widespread, dark brown, polygonal scales and generalized dryness. Cutaneous manifestations are present soon after birth and usually do not improve with age. The histopathology of XLI typically shows compact hyperkeratosis and slight acanthosis with a normal granular layer (summary by Takeichi and Akiyama, 2016). X-linked ichthyosis is fundamentally the same disorder as placental steroid sulfatase deficiency, which is often first noted in the pregnant mother of affected males by decreased estrogen or delayed progression of parturition (Alperin and Shapiro, 1997). This is thus an example of affinity ('lumping') of phenotypes thought previously to be separate, the opposite of genetic heterogeneity. Schnyder (1970) gave a useful classification of the inherited ichthyoses. Hernandez-Martin et al. (1999) provided a comprehensive review of X-linked ichthyosis. They pointed out that among all genetic disorders X-linked ichthyosis shows one of the highest ratios of chromosomal deletions; complete deletion has been found in up to 90% of patients. Takeichi and Akiyama (2016) reviewed inherited nonsyndromic forms of ichthyosis. (308100)

MalaCards based summary : Ichthyosis, X-Linked, also known as x-linked ichthyosis, is related to ichthyosis and ichthyosis, x-linked, without steroid sulfatase deficiency, and has symptoms including seizures, dry skin and intellectual disability. An important gene associated with Ichthyosis, X-Linked is STS (Steroid Sulfatase), and among its related pathways/superpathways are Steroid hormone biosynthesis and Keratinization. The drugs Paclitaxel and Selegiline have been mentioned in the context of this disorder. Affiliated tissues include skin, breast and lung, and related phenotype is Increased viability.

NIH Rare Diseases : 49 X-linked ichthyosis is a disorder in which the skin cells are produced at a normal rate but they do not separate properly at the surface of the stratum corneum (the outermost layer of the skin). This slows the rate of shedding of the skin cells, resulting in a build-up of scales. The scales of X-linked ichthyosis are often dark and usually cover only a portion of the body. Typically, the trunk and back of the neck are more likely to be affected. Scales are usually not found on the face, scalp, palms of the hands, and soles of the feet. X-linked ichthyosis mostly affects males. It is usually caused by a mutation or deletion in the STS gene and is inherited in an X-linked recessive manner. In rare cases, the ichthyosis can be part of a genetic syndrome in which other parts of the body are affected. Topical treatment may consist of alpha-hydroxy acids, lubricating bath oils, and emollients. For adult patients, systemic retinoids may be an option, especially during winter when the ichthyosis is often more severe. The ichthyosis is life-long, but the scaling may improve with age.

UniProtKB/Swiss-Prot : 71 Ichthyosis, X-linked: A keratinization disorder manifesting with mild erythroderma and generalized exfoliation of the skin within a few weeks after birth. Affected boys later develop large, polygonal, dark brown scales, especially on the neck, extremities, trunk, and buttocks.
