Genes affected

FUT2 (HGNC:4013): (fucosyltransferase 2 (H blood group)) This gene is one of two encoding the galactoside 2-L-fucosyltransferase enzyme. The encoded protein is important for the final step in the soluble ABO blood group antigen synthesis pathway. It is also involved in cell-cell interaction, cell surface expression, and cell proliferation. Mutations in this gene are a cause of the H-Bombay blood group where red blood cells lack the H antigen.

Collection Method:clinical testing

The c.413G>A (p.R138H) alteration is located in exon 2 (coding exon 1) of the FUT2 gene. This alteration results from a G to A substitution at nucleotide position 413, causing the arginine (R) at amino acid position 138 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
