Invitae RCV001036946 SCV001200336 uncertain significance Hypertrophic cardiomyopathy 2022-05-17 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 27 of the TNNI3 protein (p.Arg27Cys). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with TNNI3-related conditions. ClinVar contains an entry for this variant (Variation ID: 835941). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
Ambry Genetics RCV002416335 SCV002678615 uncertain significance Cardiovascular phenotype 2021-11-15 criteria provided, single submitter clinical testing The p.R27C variant (also known as c.79C>T), located in coding exon 3 of the TNNI3 gene, results from a C to T substitution at nucleotide position 79. The arginine at codon 27 is replaced by cysteine, an amino acid with highly dissimilar properties. This amino acid position is well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
