RCV001330304 | SCV004455983 | likely pathogenic | Intellectual disability, autosomal dominant 5 | 2023-08-10 | criteria provided, single submitter | clinical testing | This sequence change replaces serine, which is neutral and polar, with phenylalanine, which is neutral and non-polar, at codon 1212 of the SYNGAP1 protein (p.Ser1212Phe). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on SYNGAP1 protein function. ClinVar contains an entry for this variant (Variation ID: 1029091). This missense change has been observed in individual(s) with clinical features of SYNGAP1-related conditions (Invitae). In at least one individual the variant was observed to be de novo. This variant is not present in population databases (gnomAD no frequency). |
