Genes affected

FUT4 (HGNC:4015): (fucosyltransferase 4) The product of this gene transfers fucose to N-acetyllactosamine polysaccharides to generate fucosylated carbohydrate structures. It catalyzes the synthesis of the non-sialylated antigen, Lewis x (CD15). [provided by RefSeq, Jan 2009]

PIWIL4 (HGNC:18444): (piwi like RNA-mediated gene silencing 4) PIWIL4 belongs to the Argonaute family of proteins, which function in development and maintenance of germline stem cells (Sasaki et al., 2003 [PubMed 12906857]).[supplied by OMIM, Mar 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.12195319).

Feb 23, 2023

The c.283C>G (p.R95G) alteration is located in exon 1 (coding exon 1) of the FUT4 gene. This alteration results from a C to G substitution at nucleotide position 283, causing the arginine (R) at amino acid position 95 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
