Association between angiotensin‐converting enzyme gene insertion deletion polymorphism and androgenetic alopecia susceptibility among Egyptian patients: A preliminary case‐controlled study

Background Androgenetic alopecia (AGA) is a prevalent condition with a complex etiopathogenesis. Angiotensin‐converting enzyme (ACE) gene located on the chromosome 17q23 contains an insertion (I) and deletion (D) polymorphism in the intron 16. This gene polymorphism plays a role in multiple inflammatory disorders. However, there are no studies investigating its association with AGA susceptibility. Objectives In this work, we aimed at exploring the association of ACE gene I/D polymorphism in AGA susceptibility in a group of Egyptian patients. Methods This study included 100 AGA patients, and 100 apparently healthy controls. The ACE gene I/D polymorphism was analyzed by polymerase chain reaction. Results The DD, ID genotypes, and D allele showed higher frequent distribution among studied AGA patients than controls (p
