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]

Ambry Genetics

Nov 30, 2022

The c.607C>T (p.R203C) alteration is located in exon 4 (coding exon 1) of the FUT1 gene. This alteration results from a C to T substitution at nucleotide position 607, causing the arginine (R) at amino acid position 203 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
