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]

Collection Method:clinical testing

The c.713C>T (p.T238M) alteration is located in exon 2 (coding exon 2) of the FUT7 gene. This alteration results from a C to T substitution at nucleotide position 713, causing the threonine (T) at amino acid position 238 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
