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.

Benign, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	Nov 26, 2019	Variant summary: AKAP9 c.8286A>C (p.Lys2762Asn) results in a non-conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.001 in 250844 control chromosomes, predominantly at a frequency of 0.0019 within the Non-Finnish European subpopulation in the gnomAD database, including 1 homozygote. The observed variant frequency within Non-Finnish European control individuals in the gnomAD database is approximately 190 fold higher than the estimated maximal expected allele frequency for a pathogenic variant in AKAP9 causing Arrhythmia phenotype (1e-05), strongly suggesting that the variant is a benign polymorphism. c.8286A>C has been reported in the literature in heterozygous individuals without ECG signs of Long QT Syndrome (Ghouse_2015). To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Three ClinVar submissions (evaluation after 2014) cite the variant twice as likely benign and once as uncertain significance. Based on the evidence outlined above, the variant was classified as benign. -

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. -
