Familial isolated trichomegaly (disorder)
	Familial isolated trichomegaly
	A rare genetic hair anomaly with characteristics of a prolonged anagen phase of the eyelash hairs, leading to extreme eyelash growth that may result in corneal irritation. Increased growth of hair on other parts of the face (eyebrows, cheeks, forehead) and/or the body (chest, arms, legs) may be associated. There is evidence the disease is caused by homozygous mutation in the FGF5 gene on chromosome 4q21.
