Description

The filtering allele frequency of the c.2967T>C (p.Ile989=) variant in the MYH7 gene is 70.48% (7476/10406) of African chromosomes by the Exome Aggregation Consortium (http://exac.broadinstitute.org), which is a high enough frequency to be classified as benign based on thresholds defined by the ClinGen Inherited Cardiomyopathy Expert Panel (BA1; PMID:29300372).
