MBL2 and leprosy: In a northwest Brazilian population, Vasconcelos et al. (27) did not observe associations between MBL2 exon 1 variants and leprosy (27); in contrast, Sapkota et al. (20) observed that the MBL2 B variant was associated with protection to the lepromatous form compared to the tuberculoid form of leprosy in a Nepalese population (20).
