ClinVar
Submissions by phenotype
Long QT syndrome Uncertain:1
This sequence change replaces threonine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 1942 of the AKAP9 protein (p.Thr1942Asn). This variant is present in population databases (rs768512576, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with AKAP9-related conditions. ClinVar contains an entry for this variant (Variation ID: 577619). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
Cardiovascular phenotype Uncertain:1
The p.T1942N variant (also known as c.5825C>A), located in coding exon 24 of the AKAP9 gene, results from a C to A substitution at nucleotide position 5825. The threonine at codon 1942 is replaced by asparagine, an amino acid with similar properties. This amino acid position is poorly 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 alteration remains unclear. -
