Genes affected

POFUT1 (HGNC:14988): (protein O-fucosyltransferase 1) This gene encodes a member of the glycosyltransferase O-Fuc family. This enzyme adds O-fucose through an O-glycosidic linkage to conserved serine or threonine residues in the epidermal growth factor-like repeats of a number of cell surface and secreted proteins. O-fucose glycans are involved in ligand-induced receptor signaling. Alternative splicing of this gene results in two transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Likely_benign. Variant got -4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.82).
• BP6: Variant 20-32210051-C-G is Benign according to our data. Variant chr20-32210051-C-G is described in ClinVar as [Likely_benign]. Clinvar id is 2025801.Status of the report is criteria_provided_single_submitter, 1 stars.
