Summaries for Hypotrichosis Simplex

NIH Rare Diseases : 54 Hypotrichosis simplex is a rare form of hereditary hair loss without other abnormalities. Affected individuals typically show normal hair at birth, but experience hair loss and thinning of the hair shaft that starts during early childhood and progresses with age. Hypotrichosis simplex can be divided into 2 forms: the scalp-limited form and the generalized form, in which all body hair is affected. The progressive thinning of the hair shaft is a typical feature of androgenetic alopecia. Hypotrichosis simplex can be inherited either as an autosomal dominant or autosomal recessivetrait. Some cases are caused by mutations in the APCDD1 gene on chromosome 18p11. To date, there is no treatment for this condition.

MalaCards based summary : Hypotrichosis Simplex, also known as hereditary hypotrichosis simplex, is related to hypotrichosis 8 and woolly hair syndrome. An important gene associated with Hypotrichosis Simplex is APCDD1 (APC Down-Regulated 1), and among its related pathways/superpathways are Regulation of FZD by ubiquitination and Wnt signaling network. The drugs Anti-Bacterial Agents and Gentamicins have been mentioned in the context of this disorder. Affiliated tissues include skin, and related phenotypes are alopecia and sparse body hair
