Genes affected
AKAP9 (HGNC:379): (A-kinase anchoring protein 9) The A-kinase anchor proteins (AKAPs) are a group of structurally diverse proteins which have the common function of binding to the regulatory subunit of protein kinase A (PKA) and confining the holoenzyme to discrete locations within the cell. This gene encodes a member of the AKAP family. Alternate splicing of this gene results in at least two isoforms that localize to the centrosome and the Golgi apparatus, and interact with numerous signaling proteins from multiple signal transduction pathways. These signaling proteins include type II protein kinase A, serine/threonine kinase protein kinase N, protein phosphatase 1, protein phosphatase 2a, protein kinase C-epsilon and phosphodiesterase 4D3.

Significance: Likely benign
Review Status: no assertion criteria provided
Collection Method: provider interpretation

Given the limited case data and the frequency in samples unselected for long QT (1% of Finnish individuals) we consider this a variant likely benign. Di Resta et al (2015) identified this variant in one individual with Brugada syndrome. No individual phenotypic information was available, but the cohort consisted of 91 unrelated patients with Brugada syndrome on the basis of either type I ECG, spontaneous or induced by flecainide or ajmaline infusion and who were SCN5A-negative. It is a non-conservative amino acid substitution of a hydrophobic Tyrosine with a hydrophilic Histidine at a conserved residue. In silico analysis with PolyPhen2 predicts the variant is probably damaging. No other variants have been reported in this region of AKAP9. However, ExAC constraint analyses of AKAP9 appears to be tolerant to missense variation (Z= -2.75), as well as loss of function/truncating variation (pLI=0.00). The variant is listed in dbSNP (rs61757557). The ClinSeq group reported it in 1 of 854 individuals not selected for long QT syndrome (Ng et al 2013). The variant was reported online in a total of 217 of 138,602 individuals in the Genome Aggregation Consortium Dataset (gnomAD; http://gnomad.broadinstitute.org/), which currently includes variant calls on >140,000 unrelated individuals of African, Asian, European, Latino, and Ashkenazi descent. It was seen in 129 of 13,003 Finnish individuals (0.99%), 71 of 61,939 European individuals (0.11%), and 12 of 17,980 Latino individuals (0.06%). -

Significance: Likely benign
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
