RCV001986375 | SCV002287237 | likely pathogenic | Aortic valve disease 2 | 2021-10-18 | criteria provided, single submitter | clinical testing | In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. This variant disrupts the p.Asn162 amino acid residue in TBX5. Other variant(s) that disrupt this residue have been determined to be pathogenic (Invitae). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. 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 TBX5 protein function. This variant has not been reported in the literature in individuals affected with TBX5-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces asparagine with lysine at codon 162 of the TBX5 protein (p.Asn162Lys). The asparagine residue is highly conserved and there is a moderate physicochemical difference between asparagine and lysine. |
