Hypotrichosis 2

Overview

Type of disease: Rare conditions

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 recessive trait. Some cases are caused by mutations in the APCDD1 gene on chromosome 18p11. To date, there is no treatment for this condition. Source: Genetic and Rare Diseases Information Center (GARD), supported by ORDR-NCATS and NHGRI.
