Description

This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 520 of the BAG3 protein (p.Pro520Ser). This variant is present in population databases (rs760699965, gnomAD 0.01%). This missense change has been observed in individual(s) with dilated cardiomyopathy (PMID: 31737537). ClinVar contains an entry for this variant (Variation ID: 571678). 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 BAG3 protein function with a negative predictive value of 80%. 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.
