Background/Aim: Heat-shock proteins (HSPs) are molecular chaperones which modify the structures and interactions of other proteins. The aim of our study was to investigate HSP90AA1, HSP90AB1 and HSP90B1 gene polymorphisms in patients with non-small cell lung cancer (NSCLC). Materials and Methods: Ninety-seven patients with NSCLC and 97 healthy controls were included in the study. Real-time polymerase chain reaction was used for genotyping. Results: The frequency of mutant CC genotype for HSP90AA1 (rs4947C/T), mutant AA genotype for HSP90AB1 (rs13296A/G) and mutant CC genotype for HSP90B1 (rs2070908 C/G) was significantly higher in the patient group than in controls (p=0.019, p=0.004 and p=0.036, respectively). The frequency of patients with homozygote mutant allele was also significantly higher than that of controls and possessing of the mutant genotype increased the risk for disease by approximately 2.9, 4.8, 1.9 for HSP90AA1, HSP90AB1 and HSP90B1, respectively. The present study appears to be the first of its kind to report data on these gene polymorphisms in patients with NSCLC in the Turkish population.
