The clinical relevance of rare missense variants in this gene, which are identified on average once per individual sequenced in affected populations (Herman 2012), is not well understood. Yet, evidence suggests that the vast majority of such missense variants do not contribute to the clinical outcome of DCM (Begay 2015). Thus, the clinical significance of the p.Arg21867Cys variant cannot be determined with certainty.
Centre for Mendelian Genomics, University Medical Centre Ljubljana	RCV001197045	SCV001367680	uncertain significance	See cases	2020-03-17	criteria provided, single submitter	clinical testing	This variant was classified as: Uncertain significance. The available evidence on this variant's pathogenicity is insufficient or conflicting. The following ACMG criteria were applied in classifying this variant: PM2,PP3.
Ambry Genetics	RCV002336483	SCV002637763	uncertain significance	Cardiovascular phenotype	2018-01-16	criteria provided, single submitter	clinical testing	The p.R15370C variant (also known as c.46108C>T), located in coding exon 153 of the TTN gene, results from a C to T substitution at nucleotide position 46108. The arginine at codon 15370 is replaced by cysteine, an amino acid with highly dissimilar properties. This amino acid position is highly 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.
