RCV001188494 | SCV001355565 | uncertain significance | Cardiomyopathy | 2019-01-31 | criteria provided, single submitter | clinical testing | Variant of Uncertain Significance due to insufficient evidence: This variant deletes 17 nucleotides in exon 3 of the TNNI3 gene, creating a frameshift and premature translation stop signal. This variant is expected to result in an absent or non-functional protein product. 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 is rare in the general population and has been identified in 0/277264 chromosomes 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. Available evidence is insufficient to determine the role of this variant in disease conclusively. |
