Genes affected
GFPT1 (HGNC:4241): (glutamine--fructose-6-phosphate transaminase 1) This gene encodes the first and rate-limiting enzyme of the hexosamine pathway and controls the flux of glucose into the hexosamine pathway. The product of this gene catalyzes the formation of glucosamine 6-phosphate. [provided by RefSeq, Sep 2008]

ACMG classification
Classification was made for transcript
Our verdict: Uncertain_significance. The variant received 4 ACMG points.
PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 10 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 4.3482 (above the threshold of 3.09). Trascript score misZ: 4.3487 (above the threshold of 3.09). GenCC associations: The gene is linked to congenital myasthenic syndrome 12, congenital myasthenic syndromes with glycosylation defect.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.784
