    A rare case of hypotrichosis with juvenile macular dystrophy (HJMD) was identified in a six-year-old Saudi girl with sparse scalp hair and progressive vision loss. Born to consanguineous parents, she exhibited symptoms from birth, including decreased night vision and cone-rod dysfunction. Genetic analysis revealed a homozygous missense mutation, c.1918T>G (p.Cys640Gly), in the CDH3 gene. This finding contributes to the understanding of the genetic spectrum of HJMD in Saudi Arabia, highlighting the importance of genetic evaluation in patients with similar clinical features.
