Association of Single Nucleotide Polymorphisms in the CYP19A1 Gene with Female Pattern Hair Loss in a Chinese Population

Abstract

Background: It has been suggested that the single nucleotide polymorphism (SNP) of the CYP19A1 gene encoding aromatase may affect the development of female pattern hair loss (FPHL). Objective: Our aim was to investigate the association of CYP19A1 gene SNPs with FPHL in a Chinese population. Methods: Two hundred Chinese Han patients with FPHL and 200 controls were enrolled into our study. SNaPshot technology was used to detect CYP19A1 gene candidate SNPs. Results: The allele frequencies and distributions of rs6493497 and rs7176005 were significantly different between FPHL and control subjects (p < 0.001 and p < 0.001 vs. p < 0.001 and p = 0.003). Conclusion: The rs6493497 and rs7176005 SNPs of the CYP19A1 gene may be genetic markers that influence the risk of FPHL in this Chinese population.
