|---|---|---|
| (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.
