Ambry Genetics RCV000619642 SCV000737124 uncertain significance Cardiovascular phenotype 2016-09-10 criteria provided, single submitter clinical testing The c.61487_61489delATG variant (also known as p.D20496del) is located in coding exon 159 of the TTN gene. This variant results from an in-frame ATG deletion at positions 61487 to 61489. This results in the deletion of an aspartic acid residue at codon 20496, 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 6189 samples (12378 alleles) with coverage at this position. This amino acid position is well conserved in available vertebrate species. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
