RCV001955342 | SCV002209220 | uncertain significance | Rett syndrome, congenital variant | 2021-08-14 | criteria provided, single submitter | clinical testing | This sequence change replaces proline with alanine at codon 99 of the FOXG1 protein (p.Pro99Ala). The proline residue is weakly conserved and there is a small physicochemical difference between proline and alanine. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate insufficient coverage at this position in the ExAC database. This variant has not been reported in the literature in individuals affected with FOXG1-related conditions. 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 FOXG1 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. |
