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]
LINC02908 (HGNC:31426): (long intergenic non-protein coding RNA 2908)

The c.622C>T (p.R208W) 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 622, causing the arginine (R) at amino acid position 208 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
