CACNA2D3 and leprosy: Genetic variants in autophagy-related genes have been associated with susceptibility to leprosy, but their functional relevance remains incompletely understood.<h4>Methodology/principal findings</h4>We investigate the association of single nucleotide polymorphisms (SNPs) in three genes involved in autophagy, CACNA2D3, LRRK2 and IRGM.
