Ambry Genetics RCV002311117 SCV000320067 uncertain significance Familial thoracic aortic aneurysm and aortic dissection 2015-08-26 criteria provided, single submitter clinical testing The p.R1507Q variant (also known as c.4520G>A), located in coding exon 24 of the MYLK gene, results from a G to A substitution at nucleotide position 4520. The arginine at codon 1507 is replaced by glutamine, an amino acid with some highly similar properties. 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 6503 samples (13006 alleles) with coverage at this position. 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 variant remains unclear.
