Genes affected

GNAO1 (HGNC:4389): (G protein subunit alpha o1) The protein encoded by this gene represents the alpha subunit of the Go heterotrimeric G-protein signal-transducing complex. Defects in this gene are a cause of early-onset epileptic encephalopathy. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2015]

ACMG classification

Classification made for transcript

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in the GNAO1 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 70 curated pathogenic missense variants (we use a threshold of 10). The gene has 43 curated benign missense variants. Gene score misZ: 3.1919 (above the threshold of 3.09). Trascript score misZ: 4.549 (above the threshold of 3.09). GenCC associations: The gene is linked to developmental and epileptic encephalopathy, 17, neurodevelopmental disorder with involuntary movements, developmental and epileptic encephalopathy, movement disorder.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.934

PP5

Variant 16-56192252-G-T is Pathogenic according to our data. Variant chr16-56192252-G-T is described in ClinVar as [Pathogenic]. Clinvar id is 1802165.Status of the report is no_assertion_criteria_provided, 0 stars.
