Besides uncovering HLA-G as a possible causal gene involved in vitiligo pathogenesis, the present results may either reinforce the importance of HLA-A*02 alleles in the vitiligo pathogenesis, even in admixed populations, or refute the previous conclusion that HLA-A*02:01 is involved in this disease [8,9,10,11,51]. The gene discussed is HLA-G; the disease is vitiligo.
