RCV000255097 | SCV000321737 | pathogenic | not provided | 2022-01-19 | criteria provided, single submitter | clinical testing | Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 25966631, 23993195, 28973083, 28628939, 28202424, 28688840, 29100083, 30642806, 31780880, 31737037, 34440436, 34122306, 33584783) |
Invitae | RCV000468248 | SCV000550342 | pathogenic | Early infantile epileptic encephalopathy with suppression bursts | 2023-07-13 | criteria provided, single submitter | clinical testing | This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 203 of the GNAO1 protein (p.Gly203Arg). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with Ohtahara syndrome, early infantile epileptic encephalopathy, and movement disorder (PMID: 23993195, 25966631, 26060304, 27072799, 28202424). In at least one individual the variant was observed to be de novo. ClinVar contains an entry for this variant (Variation ID: 66115). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt GNAO1 protein function. Experimental studies have shown that this missense change affects GNAO1 function (PMID: 28747448). For these reasons, this variant has been classified as Pathogenic. |

RCV003421966 | SCV004118582 | pathogenic | GNAO1-Related Condition | 2022-08-29 | criteria provided, single submitter | clinical testing | The GNAO1 c.607G>A variant is predicted to result in the amino acid substitution p.Gly203Arg. This is a recurrent de novo variant reported in individuals with epileptic encephalopathy (Table 1, Nakamura et al. 2013. PubMed ID: 23993195; Arya et al. 2017. PubMed ID: 28202424; Table 1A, Fernández-Marmiesse et al. 2019. PubMed ID: 31780880). This variant has not been reported in a large population database (http://gnomad.broadinstitute.org), indicating this variant is rare. This variant is interpreted as pathogenic. |
