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]

Significance:Benign
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases was too high to be consistent with this variant causing disease. Therefore, this variant is classified as benign. -

Review Status:criteria provided, single submitter

Variant summary: The BAG3 c.1220C>T (p.Pro407Leu) variant involves the alteration of a conserved nucleotide. 2/4 in silico tools predict benign outcome for this variant (Mutation Taster not captured due to low reliability index). This variant was found in 13824/121204 control chromosomes (1012 homozygotes) from ExAC at a frequency of 0.1140556, which is approximately 2920 times the estimated maximal expected allele frequency of a pathogenic BAG3 variant (0.0000391), thus this variant is a common benign polymorphism. In addition, multiple clinical diagnostic laboratories have classified this variant as benign. In literature, this variant has been reported in one DCM patient who also carried a rare variant p.I206V and was classified as a known polymorphism (Ruppert_2013). Taken together, this variant is classified as benign. -

This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
