Abstract
Vitiligo, a complex autoimmune disorder characterized by melanocyte destruction, arises from an intricate interplay of genetic, epigenetic, immune, and environmental factors. Genome-wide association studies (GWAS) have identified over 50 susceptibility loci, including key genes within the MHC region and those involved in immunity, oxidative stress, and melanogenesis. Concurrently, epigenetic research has unraveled regulatory networks critical to vitiligo pathogenesis, with a focus on DNA methylation and non-coding RNAs (e.g., microRNAs, long non-coding RNAs, and circular RNAs). These advancements provide deeper insights into gene regulation, immune processes, and cellular dynamics. This review integrates findings from genetic and epigenetic studies to offer a comprehensive understanding of molecular mechanisms of vitiligo, paving the way for innovative, personalized therapeutic approaches.
