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]

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	Apr 02, 2019	Has not been previously published as pathogenic or benign to our knowledge; In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function -
Uncertain significance, criteria provided, single submitter	clinical testing	ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories	Dec 16, 2019	The BAG3 c.574G>A; p.Gly192Ser variant (rs201487919), to our knowledge, is not reported in the medical literature but is reported as uncertain in ClinVar (Variation ID: 471803). This variant is found in the East Asian population with an allele frequency of 0.04% (7/19,920 alleles) in the Genome Aggregation Database. The glycine at codon 192 is moderately conserved, and computational analyses (SIFT, PolyPhen-2) predict that this variant is tolerated. However, given the lack of clinical and functional data, the significance of the p.Gly192Ser variant is uncertain at this time. -

Dec 01, 2021

The p.G192S variant (also known as c.574G>A), located in coding exon 3 of the BAG3 gene, results from a G to A substitution at nucleotide position 574. The glycine at codon 192 is replaced by serine, an amino acid with similar properties. This amino acid position is not well conserved in available vertebrate species. 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. -
