Description

Segregated with HCM in one relative of a single proband tested at GeneDx and in two relatives in published literature (PMID: 34345284); Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 12820698, 27532257, 12707239, 21310275, 25132132, 30626765, 27885498, 36143288, 31941943, 31447099, 25611685, 34345284, 28606303, 38377203, 37652022, 37850193, 29300372, 32381727, 36693943)
