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.

Variant summary: AKAP9 c.4004_4006dupAAC (p.Lys1335_Leu1336insGln) results in an in-frame insertion that is predicted to insert Gln amino acid into the encoded protein. The variant allele was found at a frequency of 0.4 in 281434 control chromosomes, predominantly at a frequency of 0.63 within the African or African-American subpopulation in the gnomAD database, including 4942 homozygotes. Therefore, suggesting the variant is the major allele observed in population(s) of African-American origin. Four ClinVar submissions from clinical diagnostic laboratories (evaluation after 2014) cite the variant three times a benign and once as likely benign. Based on the evidence outlined above, the variant was classified as benign. -
