(A;A) 2 Higher vitamin B12 levels
(G;G) 2 Lower vitamin B12 levels

The reduced activity of the FUT2 enzyme with the A allele may decrease susceptibility to bacterial infection and indirectly lower the risk of vitamin B12 malabsorption, thereby resulting in higher vitamin B12 concentrations in A allele carriers.
