Hypertrichosis cubiti

Hypertrichosis cubiti, also known as hairy elbow syndrome, is a rare genetic disorder characterized by an abnormal amount of hair growth on the elbows. This condition is usually present from birth or develops in early childhood.

Symptoms

The primary symptom of hypertrichosis cubiti is excessive hair growth on the elbows. The hair can be up to 5 cm long and is typically darker than the surrounding skin. Other symptoms may include mild intellectual disability and short stature.

Causes

Hypertrichosis cubiti is believed to be caused by a mutation in the TRPS1 gene. This gene provides instructions for making a protein that regulates the growth and development of hair follicles. Mutations in the TRPS1 gene disrupt the normal development of hair follicles, leading to excessive hair growth.

Diagnosis

Diagnosis of hypertrichosis cubiti is based on the characteristic physical features. Genetic testing can confirm a diagnosis by identifying a mutation in the TRPS1 gene.

Treatment

There is currently no cure for hypertrichosis cubiti. Treatment is focused on managing the symptoms. Hair removal methods such as shaving, waxing, or laser hair removal may be used to manage the excessive hair growth.
