Genes affected
OGT (HGNC:8127): (O-linked N-acetylglucosamine (GlcNAc) transferase) This gene encodes a glycosyltransferase that catalyzes the addition of a single N-acetylglucosamine in O-glycosidic linkage to serine or threonine residues. Since both phosphorylation and glycosylation compete for similar serine or threonine residues, the two processes may compete for sites, or they may alter the substrate specificity of nearby sites by steric or electrostatic effects. The protein contains multiple tetratricopeptide repeats that are required for optimal recognition of substrates. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, Oct 2009]

ACMG classification
Classification made for transcript
Verdict is Uncertain_significance. Variant got 2 ACMG points.
PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), OGT. . Gene score misZ: 5.6667 (greater than the threshold 3.09). The gene has 12 curated pathogenic missense variants (we use a threshold of 10). The gene has 3 curated benign missense variants. GenCC has associacion of the gene with intellectual disability, X-linked 106.
BP4
Computational evidence support a benign effect (MetaRNN=0.26633492).

| Uncertain significance, no assertion criteria provided | clinical testing | PreventionGenetics, part of Exact Sciences | Feb 09, 2024 | The OGT c.522A>C variant is predicted to result in the amino acid substitution p.Glu174Asp. To our knowledge, this variant has not been reported in the literature or in a large population database, indicating this variant is rare. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. - |
