The ''T'' allele is associated with reduced plasma folate [R].

Women with CT and TT genotypes had higher red blood cell folate concentrations, not significantly associated with serum folate or homocysteine levels [R].

Methotrexate (antifolate drug) uptake was lowest in individuals with CC genotype than those with CT or TT genotypes [R].
