| Invitae | RCV001321049 | SCV001511862 | uncertain significance | Epilepsy, childhood absence 2; Febrile seizures, familial, 8 | 2023-10-03 | criteria provided, single submitter | clinical testing | This sequence change replaces isoleucine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 436 of the GABRG2 protein (p.Ile436Thr). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with GABRG2-related conditions (Invitae). This missense change has been observed in at least one individual who was not affected with GABRG2-related conditions (Invitae). ClinVar contains an entry for this variant (Variation ID: 1021310). 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 GABRG2 protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. |
