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.

Collection Method:clinical testing

The p.Arg2016Cys variant (rs376950905) has not been reported in the medical literature nor has it been previously identified in our laboratory; however, it is listed in the ClinVar database as likely benign (Variation ID: 417028). It is listed in the Genome Aggregation Database (gnomAD) browser with a frequency in Latino populations of 0.092% (identified in 31 out of 33,520 chromosomes). The arginine at codon 2016 is highly conserved considering 11 species up to Cow (Alamut software v2.9), although several species of bat and marsupial mammals have a cysteine at this position suggesting this change is evolutionary tolerated. Likewise, computational analyses suggest this variant does not have a significant effect on AKAP9 protein structure/function (SIFT: tolerated, PolyPhen2: benign, and Mutation Taster: polymorphism). However, based on the available information, the clinical significance of the p.Arg2016Cys variant cannot be determined with certainty. -

Significance:Benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This alteration is classified as 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. -
