Ambry Genetics RCV000249226 SCV000319016 uncertain significance Cardiovascular phenotype 2013-10-16 criteria provided, single submitter clinical testing The p.Q3944K variant (also known as c.11830C>A) is located in coding exon 49 of the TTNgene. This alteration results from a C to A substitution at nucleotide position 11830. The glutamine at codon 3944 is replaced by lysine, an amino acid with some similar properties. This variant was not reported in population-based cohorts in the following databases: Database of Single Nucleotide Polymorphisms (dbSNP), the 1000 Genomes Project and the NHLBI Exome Sequencing Project (ESP). In the ESP, this variant was not observed in 6085 samples (12170 alleles) with coverage at this position. Based on protein sequence alignment, this amino acid position is highly conserved in available vertebrate species.In addition, this alteration is predicted to be probably damaging by PolyPhen in silico analysis.This variant has been detected in conjunction with a pathogenic mutation in MYBPC3 by our laboratory.Since supporting evidence is limited at this time, the clinical significance of this variant remains unclear.
