Ambry Genetics RCV000244278 SCV000319997 uncertain significance Cardiovascular phenotype 2015-08-14 criteria provided, single submitter clinical testing The p.A664T variant (also known as c.1990G>A), located in coding exon 4 of the JPH2 gene, results from a G to A substitution at nucleotide position 1990. The alanine at codon 664 is replaced by threonine, an amino acid with 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 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.
