However, the Rab32 and BLOC-3 genes are present in humans and genome-wide association studies have shown that single-nucleotide polymorphisms in the Rab32 untranslated regions are associated with increased susceptibility to leprosy, a human bacterial infection caused by the intracellular bacterium Mycobacterium leprae (14, 15). The gene discussed is RAB32; the disease is bacterial infectious disease.
