FUT2

A gene on chromosome 19q13.3 that encodes a Golgi membrane protein involved in synthesising an H-antigen precursor, which is required for the final step in synthesising soluble A and B antigens. FUT2 is one of two genes that encode galactoside 2-L-fucosyltransferase.

With this study we have also shown a gene-dosage effect of the Caucasian secretor mutation, G428A, in Lewis heterozygous individuals (Le/le): the serum concentrations of CA 19-9 in FUT2 heterozygous (Se/se) individuals were higher than the concentrations in homozygous wildtype individuals (Se/Se; P = 0.
