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.

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -2 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.38563138).

BS1

Variant frequency is greater than expected in population sas. GnomAdExome4 allele frequency = 0.0000246 (36/1460640) while in subpopulation SAS AF = 0.000255 (22/86190). AF 95% confidence interval is 0.000173. There are 1 homozygotes in GnomAdExome4. There are 23 alleles in the male GnomAdExome4 subpopulation. Median coverage is 30. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

The c.4C>T (p.R2W) 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 4, causing the arginine (R) at amino acid position 2 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
