Vitiligo is an acquired pigmentary disorder with several proposed pathogenesis mechanisms and complex multifactorial genetic predisposition. We analyzed 65 polymorphisms in genes potentially relevant to vitiligo pathogenesis mechanism to reveal novel and confirm reported genetic risk factors in general Russian population. We found that polymorphism rs1138272 (TC + CC) in GSTP1 gene encoding enzyme involved in xenobiotic metabolism is associated with vitiligo (Bonferroni adjusted P value 0.0015) with extraordinary high odds ratio 13.03, and haplotype analysis confirmed association of GSTP1 gene with vitiligo risk. Moreover, analysis of variations in several genes encoding enzymes of xenobiotic metabolism showed that higher risk of vitiligo is associated with higher number of risk alleles. This finding reveals possible contribution of genetic background to observed imbalance of oxidative stress control in vitiligo through cumulative effect of multiple genetic variations in xenobiotic metabolizing genes, supporting the concept of multigenic nature of vitiligo with multiple low-risk alleles cumulatively contributing to vitiligo risk.
I support the petition to designate June 25 as Vitiligo World Day and save millions of people worldwide from social isolation and persecution.
