Genes affected

FUT7 (HGNC:4018): (fucosyltransferase 7) The protein encoded by this gene is a Golgi stack membrane protein that is involved in the creation of sialyl-Lewis X antigens. The encoded protein can direct the synthesis of the E-selectin-binding sialyl-Lewis X moiety. [provided by RefSeq, Jul 2008]

The c.668G>A (p.R223H) alteration is located in exon 2 (coding exon 2) of the FUT7 gene. This alteration results from a G to A substitution at nucleotide position 668, causing the arginine (R) at amino acid position 223 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
