The Ile1216Val variant in the DSP gene has not been reported as a disease-causing mutation or as a benign polymorphism to our knowledge. Although Ile1216Val results in a conservative amino acid substitution of one non-polar amino acid for another, this substitution occurs at a position that is conserved across species. The Ile1216Val variant was not observed in approximately 6000 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. However, Ile1216Val was observed in 0.4% of Asian alleles in the 1000 Genomes database. In silico algorithms are not consistent in their predictions but at least two concur that Ile1216Val is benign to the protein structure/function. In addition, mutations in nearby residues have not been reported (van der Zwaag P et al., 2009) indicating this region of the protein may tolerate change. With the clinical and molecular information available at this time, we cannot definitively determine if Ile1216Val is a disease-causing mutation or a rare benign variant. The variant is found in ARVC panel(s).
