Ambry Genetics RCV000618185 SCV000737129 uncertain significance Cardiovascular phenotype 2020-05-20 criteria provided, single submitter clinical testing The p.Y19561H variant (also known as c.58681T>C), located in coding exon 153 of the TTN gene, results from a T to C substitution at nucleotide position 58681. The tyrosine at codon 19561 is replaced by histidine, an amino acid with similar properties. This amino acid position is not well conserved in available 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.

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.Tyr28626His variant cannot be determined with certainty. References: Begay RL et al. Role of Titin Missense Variants in Dilated Cardiomyopathy.
