Genome-wide association studies have ascertained single nucleotide polymorphisms (SNPs) within the major histocompatibility complex (MHC) on chromosome 6p21 as the most prominent inherited variant connected with leprosy (Wong et al., 2010) (Zhang F. R. et al., 2009) (Liu et al., 2015) (Wang et al., 2016) (Liu et al., 2017). The gene discussed is HLA-C; the disease is leprosy.
