Genes affected
FUT8 (HGNC:4019): (fucosyltransferase 8) This gene encodes an enzyme belonging to the family of fucosyltransferases. The product of this gene catalyzes the transfer of fucose from GDP-fucose to N-linked type complex glycopeptides. This enzyme is distinct from other fucosyltransferases which catalyze alpha1-2, alpha1-3, and alpha1-4 fucose addition. The expression of this gene may contribute to the malignancy of cancer cells and to their invasive and metastatic capabilities. Alternative splicing results in multiple transcript variants.

Collection Method:clinical testing

The c.202C>T (p.R68W) alteration is located in exon 3 (coding exon 1) of the FUT8 gene. This alteration results from a C to T substitution at nucleotide position 202, causing the arginine (R) at amino acid position 68 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
