Transcobalamin 776C→G polymorphism is associated with peripheral neuropathy in elderly individuals with high folate intake
folate folic acid peripheral neuropathy TCN2 776C>G polymorphism transcobalamin vitamin B-12
2016/10/12
Background: The 776C→G polymorphism of the vitamin B-12 transport protein transcobalamin gene (TCN2) (rs1801198; Pro259Arg) is associated with a lower holotranscobalamin concentration in plasma. This ...
The important study by Brito et al. (1) suggests that a single high dose of vitamin B-12 can improve peripheral sensory nerve function in asymptomatic elderly subjects with vitamin B-12 deficiency and...
