Color RCV000771973 SCV000904927 uncertain significance Cardiomyopathy 2018-10-02 criteria provided, single submitter clinical testing Variant of Uncertain Significance due to insufficient evidence: This is a synonymous variant that does not change the amino acid sequence of the DSC2 protein. However, computational splicing tools suggest that this variant may impact RNA splicing. To our knowledge, functional assays have not been performed for this variant nor has this variant been reported in individuals affected with cardiovascular disorders in the literature. This variant has been identified in 10/246062 chromosomes in the general population by the Genome Aggregation Database (gnomAD). Available evidence is insufficient to determine the pathogenicity of this variant conclusively.
Stanford Center for Inherited Cardiovascular Disease, Stanford University RCV000223837 SCV000280079 uncertain significance not specified 2014-05-16 no assertion criteria provided clinical testing Note this variant was found in clinical genetic testing performed by one or more labs who may also submit to ClinVar. Thus any internal case data may overlap with the internal case data of other labs. The interpretation reviewed below is that of the Stanford Center for Inherited Cardiovascular Disease. This variant is located in exon 4 (of 16 exons) does not change the amino acid at codon 136, however BDGP and ESEfinder splice prediction tools predict this alteration to create an alternate donor splice site. There is no direct function evidence available. The arginine at codon 136 is conserved across species, as are neighboring amino acids. In total the variant has not been seen in ~6,500 individuals from publicly available population datasets. There is no variation at codon 136 listed in the NHLBI Exome Sequencing Project dataset, which currently includes variant calls on ~6,500 Caucasian and African American individuals (as of 11/22/13). Note that this dataset does not match the patient's ancestry (Asian). There is also no variation at this codon listed in dbSNP or 1000 genomes (as of 11/22/13).
