Eurofins Ntd Llc (ga) RCV000407738 SCV000341097 uncertain significance not provided 2017-12-22 criteria provided, single submitter clinical testing
Ambry Genetics RCV002401996 SCV002706518 uncertain significance Cardiovascular phenotype 2020-01-17 criteria provided, single submitter clinical testing The p.G3509V variant (also known as c.10526G>T), located in coding exon 44 of the TTN gene, results from a G to T substitution at nucleotide position 10526. The glycine at codon 3509 is replaced by valine, an amino acid with dissimilar properties. This amino acid position is not well conserved in available vertebrate species, and valine is the reference amino acid in other vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.

GeneDx RCV000407738 SCV003845449 uncertain significance not provided 2022-09-27 criteria provided, single submitter clinical testing Not observed at significant frequency in large population cohorts (gnomAD); Missense variant in a gene in which most reported pathogenic variants are truncating/loss of function; Has not been previously published as pathogenic or benign to our knowledge; Located in a region of TTN within the I-band in which the majority of loss of function variants are significantly associated with autosomal dominant titinopathies (Deo et al., 2016; Schafer et al., 2017)
PreventionGenetics, part of Exact Sciences RCV004529474 SCV004111452 uncertain significance TTN-related disorder 2023-06-27 criteria provided, single submitter clinical testing The TTN c.11615G>T variant is predicted to result in the amino acid substitution p.Gly3872Val. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0031% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/2-179606345-C-A). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
