GeneDx RCV000183940 SCV000236432 uncertain significance not provided 2015-09-22 criteria provided, single submitter clinical testing p.Asp251Asn (GAT>AAT): c.751 G>A in exon 9 of the TMEM43 gene (NM_024334.2). The Asp251Asn variant in the TMEM43 gene has not been reported as a disease-causing mutation or as a benign polymorphism to our knowledge. Asp251Asn results in a semi-conservative amino acid substitution of negatively charged Aspartic acid with a neutral, polar Asparagine at a position that is conserved in mammals. In silico analysis predicts Asp251Asn is benign to the protein structure/function. The Asp251Asn variant was not observed with any significant frequency in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project. Nevertheless, no mutations in nearby residues have been reported in association with ARVC. With the clinical and molecular information available at this time, we cannot definitively determine if Asp251Asn is a disease-causing mutation or a rare benign variant. The variant is found in ARVC panel(s).
