Labcorp Genetics (formerly Invitae), Labcorp RCV003643821 SCV004492153 pathogenic Atrioventricular septal defect 4 2023-08-25 criteria provided, single submitter clinical testing This sequence change replaces cysteine, which is neutral and slightly polar, with serine, which is neutral and polar, at codon 295 of the GATA4 protein (p.Cys295Ser). For these reasons, this variant has been classified as Pathogenic. 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 GATA4 protein function. This missense change has been observed in individual(s) with structural heart defect(s) (Invitae). In at least one individual the variant was observed to be de novo. This variant is not present in population databases (gnomAD no frequency).
