However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 0.0014 in 276194 control chromosomes, predominantly at a frequency of 0.015 within the African subpopulation in the gnomAD database, including 4 homozygotes. The observed variant frequency within African control individuals in the gnomAD database is approximately 600-fold of the estimated maximal expected allele frequency for a pathogenic variant in LDB3 causing Cardiomyopathy phenotype (2.5e-05), strongly suggesting that the variant is a benign polymorphism found primarily in populations of African origin. To our knowledge, no occurrence of c.1014A>G in individuals affected with 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.
