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]

The p.Asn67Ser variant in BAG3 has not been previously reported in individuals w ith cardiomyopathy but has been identified in 2/67682 European chromosomes and 2 /10572 African chromosomes by the Exome Aggregation Consortium (ExAC, http://exa c.broadinstitute.org; dbSNP rs572036022). Computational prediction tools and con servation analysis do not provide strong support for or against an impact to the protein. In summary, the clinical significance of the p.ASn67Ser variant is unc ertain. -

The p.N67S variant (also known as c.200A>G), located in coding exon 2 of the BAG3 gene, results from an A to G substitution at nucleotide position 200. The asparagine at codon 67 is replaced by serine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
