Studies finding protective effects against cancer: A meta-analysis found that two copies of the C677T variant (AA genotype) decrease the risk of colon cancer by about 20%![ref] Another meta-analysis found that two copies of the C677T variant (AA genotype) were protective against prostate cancer .[ref] The MTHFR C677T variant decreases the relative risk of retinoblastoma and oral squamous cell cancer.[ref][ref] Two copies of the C677T variant (AA genotype) are protective against gastric cancer.[ref] However, for someone who has cancer, the MTHFR C677T variant is associated with poorer outcomes.[ref] The MTHFR A1298C variant (GG or GT) is associated with a decreased risk of hypothyroidism .[ref] The flip side: Folate can also help protect against cancerous mutations in the first place

However, these effects have not been firmly established in large human clinical trials
