Abstract
Vitiligo is an autoimmune disease in which depigmented skin results from destruction of skin melanocytes, with strong epidemiologic association with several other autoimmune diseases. In previous linkage and genome-wide association studies (GWAS1, GWAS2), we identified 27 vitiligo susceptibility loci in patients of European (EUR) ancestry. We carried out a third GWAS (GWAS3) of vitiligo in EUR subjects, with augmentation of GWAS1 and GWAS2 controls, genome-wide imputation, and meta-analysis of all three vitiligo GWAS, followed by an independent replication study. The combined analyses, with 4,680 vitiligo cases and 39,586 controls, identified 23 novel replicated loci, as well as 7 new suggestive loci, most encoding immune regulators, apoptotic regulators, and melanocyte regulators, several of which are also associated with other autoimmune diseases. Functional analyses indicate a predominance of causal regulatory variation, in some cases corresponding to eQTL at these loci. Together, the identified genes provide a framework for vitiligo genetic architecture and pathobiology, highlight genetic relationships to other autoimmune diseases and melanoma, and offer potential targets for vitiligo treatment.
