N2 - Host genetic susceptibility to adult pulmonary Mycobacterium avium complex disease remains unknown. To identify genetic loci for the disease, we prepared 3 sets of pooled DNA samples from 300 patients and 300 sexmatched control subjects and genotyped 19,651 microsatellite markers in a case-control manner. D6S0009ilocated in the MICA (major histocompatibility complex class I chain-related A) gene, which encodes a ligand of the NKG2D receptor-had the lowest P value in pooled and individual DNA typing. The A6 allele of the microsatellite was significantly associated with female patients (P< .001 ), whereas the classical HLA-B and HLA-DRBl alleles did not show significant association. Functional analysis of allelic expression imbalance revealed that A6derived messenger RNA was more highly expressed than non-A6-derived messenger RNA in human bronchial epithelial cells. MICA was expressed in bronchiolar epithelium, alveolar macrophages, and granulomatous lesions. These findings suggest that MICA might be one of the immune molecules affecting the pathogenesis of the disease.
