However, significant differences between the three types of leprosy patients regarding percent distributions of IL-17A genotypes (p = 0.001) and alleles (p = 0.005) were demonstrated, as IL-17A (rs2275913A/G) GG genotype besides G allele were associated significantly with LL, while AG genotype was significantly associated with TL cases (Table 3). The gene discussed is IL17A; the disease is leprosy.
