Involvement in diseasei

Monilethrix (MNLIX)4 Publications

The disease is caused by mutations affecting the gene represented in this entry.

Disease descriptionA disorder clinically characterized by alopecia and follicular papules. Affected hairs have uniform elliptical nodes of normal thickness and intermittent constrictions, internodes at which the hair easily breaks. Usually only the scalp is involved, but in severe forms, the secondary sexual hair, eyebrows, eyelashes, and nails may also be affected.
