Description

This variant inserts 1 nucleotide in exon 4 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, this variant has not been reported in individuals affected with TNNI3-related disorders in the literature. This variant has been identified in 1/31390 chromosomes in the general population by the Genome Aggregation Database (gnomAD). Clinical relevance of loss-of-function TNNI3 truncation variants in autosomal dominant cardiovascular disorders 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.
