HSP90B1 and chronic obstructive pulmonary disease: The rs2070908 in HSP90B1 (in the heat shock protein 90 gene complex) was associated with a decreased risk (p < 0.01, OR = 0.6) of suffering from COPD among the subjects chronically exposed to biomass, and the rs13296 GG genotype with a lower risk (p = 0.01, OR = 0.22) of severe COPD in smokers [179].
