TLDR Mutations in the hairless gene cause a rare form of permanent hair loss.
The study investigated congenital atrichia with papular lesions (APL), a rare form of irreversible alopecia, in four consanguineous families. It identified the human hairless (HR) gene on chromosome 8p21.1 as the locus associated with APL. DNA sequence analysis revealed three novel mutations in the HR gene: two nonsense mutations (p.Cys690X, p.Arg819X) and one missense mutation (p.Pro1157Arg). These findings contributed to understanding the genetic basis of APL, highlighting the role of HR gene mutations in this condition.
