This study investigated the potential role of vitamin D-receptor (VDR) gene polymorphisms in susceptibility to lung disease caused by non-tuberculous mycobacteria (NTM). TaqI and FokI polymorphisms were compared in 124 patients and 127 controls. The genotype, allele and haplotype frequencies did not differ between patients and controls. TaqI and FokI polymorphisms of the VDR gene do not appear to be responsible for host susceptibility to NTM lung disease, at least in this Korean population. An association cannot, however, be completely ruled out, as only two single nucleotide polymorphisms of the VDR gene were studied in this report.
