Scientists from from Colombia, Rockefeller and Stanford Universities, believe they have discovered a gene that significantly impacts hair growth as well as hair follicle miniaturization; the phenomenon that is the cornerstone of male and female pattern baldness.
The gene identified is named APCDD1 (adenomatosis polyposis down-regulated 1), and was found in patients suffering with hereditary hypotrichosis simplex, a condition that usually presents itself in childhood. Hereditary hypotrichosis simplex is a rare autosomal dominant form of hair loss characterized by hair miniaturization, a process in which the hair follicle actually shrinks and normal thick terminal hair is gradually replaced with fine, velus hair.
