Ambry Genetics | RCV000621935 | SCV000736693 | uncertain significance | Cardiovascular phenotype | 2016-10-31 | criteria provided, single submitter | clinical testing | The p.C17017S variant (also known as c.51049T>A), located in coding exon 153 of the TTN gene, results from a T to A substitution at nucleotide position 51049. The cysteine at codon 17017 is replaced by serine, an amino acid with dissimilar properties. This alteration 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: ExAC, Database of Single Nucleotide Polymorphisms (dbSNP), NHLBI Exome Sequencing Project (ESP), and 1000 Genomes Project. In the ESP, this variant was not observed in 5988 samples (11976 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 variant remains unclear. |
