BRCA1 and lung cancer: The TC/CC genotypes of BRCA1 rs1799966 were associated with a lower risk of death (hazard ratio = 0.617, p = 0.028), and the C allele (TC + CC vs. TT) of rs1799966 was associated with a good response to chemotherapy (OR = 0.402, p = 0.008) in patients with lung cancer in the Chinese population [50].
