Submissions by phenotype
not provided Uncertain:1
This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 652 of the TCF3 protein (p.Gly652Arg). This variant is present in population databases (rs755856969, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with TCF3-related conditions. ClinVar contains an entry for this variant (Variation ID: 1465289). Invitae Evidence 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 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 TCF3 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. -
