Genes affected

FUT1 (HGNC:4012): (fucosyltransferase 1 (H blood group)) This gene encodes a Golgi stack membrane protein that is involved in the creation of a precursor of the H antigen, which is required for the final step in the synthesis of soluble A and B antigens. This is one of two genes encoding the galactoside 2-L-fucosyltransferase enzyme. Mutations in this gene are a cause of the H-Bombay blood group. [provided by RefSeq, Aug 2016]

The c.986C>A (p.T329N) alteration is located in exon 4 (coding exon 1) of the FUT1 gene. This alteration results from a C to A substitution at nucleotide position 986, causing the threonine (T) at amino acid position 329 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
