RCV001176820 | SCV001340880 | uncertain significance | Cardiomyopathy | 2019-11-14 | criteria provided, single submitter | clinical testing | This variant results in a duplication of 8 nucleotides in exon 5 of the TNNI3 gene, resulting in a frameshift and premature translation stop signal. To our knowledge, functional studies have not been performed for this variant. This variant has not been reported in individuals affected with cardiovascular disorders in the literature. This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). Disease-causing variants in TNNI3 are mostly missense variants that act in a dominant-negative manner. The role of TNNI3 truncation variants in cardiomyopathy is not clearly established. The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. |
