Genes affected
BAG3 (HGNC:939): (BAG cochaperone 3) BAG proteins compete with Hip for binding to the Hsc70/Hsp70 ATPase domain and promote substrate release. All the BAG proteins have an approximately 45-amino acid BAG domain near the C terminus but differ markedly in their N-terminal regions. The protein encoded by this gene contains a WW domain in the N-terminal region and a BAG domain in the C-terminal region. The BAG domains of BAG1, BAG2, and BAG3 interact specifically with the Hsc70 ATPase domain in vitro and in mammalian cells. All 3 proteins bind with high affinity to the ATPase domain of Hsc70 and inhibit its chaperone activity in a Hip-repressible manner. [provided by RefSeq, Jul 2008]

Myofibrillar myopathy 6;C3151293:Dilated cardiomyopathy 1HH Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingInvitaeFeb 20, 2023This sequence change replaces proline, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 97 of the BAG3 protein (p.Pro97Ala). This variant is present in population databases (rs747274078, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with BAG3-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 expected to disrupt BAG3 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. -
