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]

Benign, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	Oct 07, 2024	Variant summary: BAG3 c.1240G>A (p.Glu414Lys) results in a conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.00033 in 282702 control chromosomes, including 1 homozygote. The observed variant frequency is approximately 8-fold of the estimated maximal expected allele frequency for a pathogenic variant in BAG3 causing Dilated Cardiomyopathy phenotype (3.9e-05). A variant, reported as BAG3 G414K (correctly name should be E414K), was listed to be found in a cohort of patients affected with sporadic inclusion body myositis (Weihl_2015), however no supportive evidence for causality was provided. To our knowledge, no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 162784). Based on the evidence outlined above, the variant was classified as benign. -
Uncertain significance, criteria provided, single submitter	clinical testing	Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	Aug 27, 2014	Variant classified as Uncertain Significance - Favor Benign. The Glu414Lys varia nt in BAG3 has not been previously reported in individuals with cardiomyopathy, but has been identified in 3/8600 European American chromosomes by the NHLBI Exo me Sequencing Project (http://evs.gs.washington.edu/EVS/; dbSNP rs117749531). Gl utamic acid (Glu) at position 414 is not conserved in mammals or evolutionarily distant species, raising the possibility that a change at this position may be t olerated. Additional computational prediction tools suggest that this variant ma y not impact the protein, though this information is not predictive enough to ru le out pathogenicity. In summary, while the clinical significance of the Glu414L ys variant is uncertain, these data suggest that it is more likely to be benign. -

Illumina Laboratory Services, Illumina

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. -

Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -

This alteration is classified as likely 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. -
