Therefore, it has been classified as a Variant of Uncertain Significance. 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 not expected to disrupt LGI1 protein function. ClinVar contains an entry for this variant (Variation ID: 301656). This missense change has been observed in individual(s) with Rubenstein-Taybi syndrome and/or epilepsy (PMID: 29133209). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 273 of the LGI1 protein (p.Arg273Gln). |
