Ambry Genetics RCV000620802 SCV000735370 uncertain significance Cardiovascular phenotype 2016-05-20 criteria provided, single submitter clinical testing The p.M9246T variant (also known as c.27737T>C), located in coding exon 110 of the TTN gene, results from a T to C substitution at nucleotide position 27737. The methionine at codon 9246 is replaced by threonine, an amino acid with similar properties, and is located in the A-band region of the N2-B isoform of the titin protein. 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 5996 samples (11992 alleles) with coverage at this position. 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.
