GeneDx RCV000676884 SCV000251043 uncertain significance not provided 2018-10-10 criteria provided, single submitter clinical testing The L74V variant has not been published as a pathogenic variant, nor has it been reported as a benign polymorphism to our knowledge. The L74Vvariant was observed at a frequency of 0.5%, 47/8598 alleles, in individuals of European ancestry by theNHLBI Exome Sequencing Project, with the reported genotypes indicating that all individuals wereheterozygous for this variant. The L74V variant was also observed in 2/196 alleles from individuals ofItalian ancestry and in 2/178 alleles in individuals of British ancestry by the 1000 Genomes Project (Kerseyet al., 2010). The L74V variant is a conservative amino acid substitution, which is not likely to impactsecondary protein structure as these residues share similar properties. This substitution occurs at a positionthat is conserved across species. In silico analysis predicts this variant is probably damaging to the proteinstructure/function. Therefore, based on the currently available information, it is unclear whether this variantis a pathogenic or a rare benign variant
