Ambry Genetics RCV000618896 SCV000736551 uncertain significance Cardiovascular phenotype 2016-02-01 criteria provided, single submitter clinical testing The p.L2543F variant (also known as c.7629G>T), located in coding exon 31 of the TTN gene, results from a G to T substitution at nucleotide position 7629. The leucine at codon 2543 is replaced by phenylalanine, an amino acid with highly similar properties. This variant was previously reported in the SNPDatabase as rs372080212. Based on data from the NHLBI Exome Sequencing Project (ESP), the T allele has an overall frequency of approximately 0.01% (1/13004) total alleles studied, having been observed in 0.02% (1/4406) African American alleles. Based on data from ExAC, the T allele has an overall frequency of approximately 0.005% (6/120324). The highest observed frequency was 0.05% (5/10074) of African alleles (Exome Aggregation Consortium (ExAC), Cambridge, MA (URL: http://exac.broadinstitute.org) [Accessed February 1, 2016]). This amino acid position is highly 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.
