X-linked hypertrichosis

X-linked hypertrichosis
Other names	X-linked congenital generalized hypertrichosis
X-linked hypertrichosis is an X-linked dominant disorder.
Specialty	Dermatology

X-linked hypertrichosis, also known as X-linked congenital generalized hypertrichosis, is a hereditary disorder characterized by generalized congenital hypertrichosis and thick eyebrows. ^[1]

Signs and symptoms

Hypertrichosis is characterized as excessive hair growth anywhere on the body, in either men or women. ^[2] X-linked hypertrichosis affects males more than females. ^[3]

Causes

X-linked hypertrichosis was first mapped in chromosome Xq24-q27.1 in a Mexican family; however, the underlying genetic facts remain unknown. ^[4] X-linked hypertrichosis is inherited in an X-linked dominant pattern of inheritance. ^[3]
