TLDR A specific gene mutation causes hair loss and potential eye issues, even if vision seems normal.
The study investigated the molecular basis of hypotrichosis in two Arab Muslim siblings with sparse and short hair but no visual symptoms. Mutation analysis revealed a novel nonsense mutation (Y615X) in the CDH3 gene, which is known to cause hypotrichosis with juvenile macular dystrophy (HJMD). Despite normal visual acuity, significant macular degenerative changes were observed. The findings suggested that patients with congenital hypotrichosis should have thorough fundus examinations to detect pigmentary macular changes indicative of a CDH3 mutation.
