We previously assessed the relationship between three different SNPs of TGFβ1 [rs1800469 (C–509T), rs1800471 (G915C), and rs1982073 (T+29C)] and the development of radiation pneumonitis in patients with NSCLC treated with radiochemotherapy and observed that the CT/CC genotypes of TGFβ1 rs1982073 (T+29C) were associated with significantly lower risk of radiation pneumonitis [24]. The gene discussed is TGFB1; the disease is radiation pneumonitis.
