• Clinical Significance: Uncertain significance criteria provided, single submitter U:1
• Conservation: PhyloP100: 0.141

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 Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.025893807).

Ambry Genetics

Jul 09, 2021

The c.94T>G (p.S32A) alteration is located in exon 1 (coding exon 1) of the FUT4 gene. This alteration results from a T to G substitution at nucleotide position 94, causing the serine (S) at amino acid position 32 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
