Can premature greying be linked with mthfr 677 tt?

MTHFR 677TT Mutation: Yes, a mutation of the gene coding for this complex biochemical intermediate has far reaching implications, depending on the extent of the "mis coding." Premature hair grey ing is a known feature, but diverse developmental, neuro behavioral, cardiovascular, and other complications are all part of the disorder. It is very common, but your provider, with your specific test results, can provide help.

SOD: I think premature graying is more linked to SOD and other mutations. Decreased ability to deal with oxidative damage leads to gray hair.
