However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 0.00076 in 250886 control chromosomes, predominantly at a frequency of 0.0093 within the African or African-American subpopulation in the gnomAD database. The observed variant frequency within African or African-American control individuals in the gnomAD database is approximately 238 fold of the estimated maximal expected allele frequency for a pathogenic variant in BAG3 causing Dilated Cardiomyopathy phenotype (3.9e-05), strongly suggesting that the variant is a benign polymorphism found primarily in populations of African or African-American origin. To our knowledge, no occurrence of c.181-9T>A in individuals affected with Dilated Cardiomyopathy and no experimental evidence demonstrating its impact on protein function have been reported. Two clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. Both laboratories classified the variant as benign. Based on the evidence outlined above, the variant was classified as benign. (less)

Comment:

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.

Comment:

c.181-9T>A in Intron 01 of BAG3: This variant is not expected to have clinical s ignificance because it has been identified in 1.0% (38/3738) of African American chromosomes from a broad population by the NHLBI Exome Sequencing Project (http ://evs.gs.washington.edu/EVS; dbSNP rs139232658).
