Submissions by phenotype
Long QT syndrome Uncertain:1
This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with an AKAP9-related disease. This sequence change replaces valine with isoleucine at codon 2008 of the AKAP9 protein (p.Val2008Ile). The valine residue is highly conserved and there is a small physicochemical difference between valine and isoleucine. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). In summary, this variant is a novel missense change with uncertain impact on protein function. It has been classified as a Variant of Uncertain Significance. -
Cardiovascular phenotype Uncertain:1
The p.V2008I variant (also known as c.6022G>A), located in coding exon 25 of the AKAP9 gene, results from a G to A substitution at nucleotide position 6022. The valine at codon 2008 is replaced by isoleucine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. -
