Ambry Genetics RCV000253561 SCV000319624 uncertain significance Cardiovascular phenotype 2015-05-21 criteria provided, single submitter clinical testing The p.R24993K variant (also known as c.74978G>A), located in coding exon 185 of the TTN gene, results from a G to A substitution at nucleotide position 74978. The arginine at codon 24993 is replaced by lysine, an amino acid with highly similar properties. This variant was not reported in population based cohorts in the following databases: Database of Single Nucleotide Polymorphisms (dbSNP), NHLBI Exome Sequencing Project (ESP), and 1000 Genomes Project. In the ESP, this variant was not observed in 6074 samples (12148 alleles) with coverage at this position. This amino acid position is well conserved in available vertebrate species, except lysine is the reference amino acid in two fish 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 p.R24993K remains unclear.
