VDR and infection: Searches for polymorphisms of the CARD15 (NOD2) [46,47,48], SLC11a1 (NRAMP1) [49,50,51], LRRK2 [52,53], PTPN2/22 [54] and VDR [55] genes have been productive as they reveal susceptibilities for infection by mycobacteria due to impaired pathogen recognition or failure of phagosome maturation.
