Labcorp Genetics (formerly Invitae), Labcorp RCV001040750 SCV001204339 pathogenic Rett syndrome, congenital variant 2023-08-15 criteria provided, single submitter clinical testing This sequence change replaces isoleucine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 266 of the FOXG1 protein (p.Ile266Ser). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with clinical features of FOXG1-related conditions (Invitae). In at least one individual the variant was observed to be de novo. ClinVar contains an entry for this variant (Variation ID: 839069). 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 FOXG1 protein function. For these reasons, this variant has been classified as Pathogenic.
