X-linked Hypertrichosis

X-linked hypertrichosis (pronunciation: eks-linkt hahy-per-tri-koh-sis) is a rare genetic disorder characterized by excessive hair growth on various parts of the body. The condition is inherited in an X-linked dominant manner.

Etymology

The term 'hypertrichosis' is derived from the Greek words 'hyper' meaning 'excessive' and 'trichos' meaning 'hair'. The prefix 'X-linked' refers to the fact that the gene responsible for the condition is located on the X chromosome.

Definition

X-linked hypertrichosis is a condition that causes excessive hair growth in certain areas of the body. The hair growth is not limited to areas where hair is normally present, but can also occur in areas where hair is typically absent or minimal.

Symptoms

The primary symptom of X-linked hypertrichosis is excessive hair growth, which can occur on any part of the body, but is most commonly seen on the face, back, and extremities. Other symptoms may include alopecia (hair loss), dysplasia (abnormal tissue development), and ectodermal dysplasia (abnormal development of the skin and associated structures).

Causes

X-linked hypertrichosis is caused by mutations in the FMR1 gene, which is located on the X chromosome. This gene is involved in the regulation of hair growth. Mutations in this gene disrupt the normal regulation of hair growth, leading to the excessive hair growth seen in this condition.

Treatment

Treatment for X-linked hypertrichosis primarily involves managing the symptoms. This may include hair removal techniques such as shaving, waxing, or laser hair removal. In some cases, medication may be used to slow hair growth.
