However, methylenetetrahydrofolate reductase (rs1801133 and rs1801131), vitamin D receptor (TaqI and Fok1), and interleukin-16 (rs4778889 and rs11556218) gene polymorphisms were not associated with the risk of renal cell carcinoma.
The results presented here indicate that the two MTHFR gene polymorphisms are significantly associated with the risk of RCCs in a cohort of Pakistani patients and may be useful as susceptibility markers in other populations of the world as well.
Having at least 1 variant T allele of MTHFRA222V was associated with higher RCC risk compared to those with 2 common (CC) alleles (OR = 1.44; 95% CI: 1.17-1.77; p = 0.001).
