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%). |
