A study of families of leprosy patients, whose groups were divided by subtypes (286 MB descendants and 188 PB descendants), in Vietnam for the CCDC122-LACC1 locus, identified the polymorphic “A” alleles, “G” and “A” for SNPs rs3088362, rs3764147 and rs10507522, respectively [34]. This evidence concerns the gene CCDC122 and leprosy.
