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.

The AKAP9 c.3580G>A; p.Ala1194Thr variant (rs139965373, ClinVar variant ID 180262) has been detected in large whole-exome datasets from a cohort of SIDS patients (Neubauer 2017) and an unselected population (Ng 2013). This variant is listed in the genome Aggregation Database (gnomAD) with an overall population frequency of 0.06% (identified on 159 out of 276,956 chromosomes, including one homozygote). The alanine at position 1194 is highly conserved, considering 11 species, and computational analyses of the effects of the p.Ala1194Thr variant on protein structure and function predict a deleterious effect (SIFT: damaging, PolyPhen-2: possibly damaging). Based on the available information, the clinical significance of the p.Ala1194Thr variant cannot be determined with certainty.

Variant summary: AKAP9 c.3580G>A (p.Ala1194Thr) results in a non-conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.00061 in 251174 control chromosomes, predominantly at a frequency of 0.00095 within the Latino subpopulation in the gnomAD database. The observed variant frequency within Latino control individuals in the gnomAD database is approximately 95 fold of 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 found primarily in populations of Latino origin. c.3580G>A has been reported in the literature in individuals affected with Sudden infant death syndrome, Hypertrophic Cardiomyopathy and prostate cancer (Neubauer_2017, Forleo_2017, Belic_2018). These reports do not provide unequivocal conclusions about association of the variant with Arrhythmia. Additionally, co-occurrences with other pathogenic variants have been reported (MYBPC3 c.506-2A>C; BRCA2 c.4091_4092insAA, p.I1364fs) (Forleo_2017, Belic_2018), providing supporting evidence for a benign role. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Six ClinVar submitters (evaluation after 2014) cite the variant as benign (1x) and uncertain significance (5x). Based on the evidence outlined above, the variant was classified as likely benign.

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.
