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]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -11 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.18982214).

BP6

Variant 10-119676990-C-T is Benign according to our data. Variant chr10-119676990-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 192113.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00088 (134/152246) while in subpopulation AFR AF = 0.00313 (130/41548). AF 95% confidence interval is 0.00269. There are 0 homozygotes in GnomAd4. There are 58 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High AC in GnomAd4 at 134 AD gene.
