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.

Uncertain significance, criteria provided, single submitter	research	Dept of Medical Biology, Uskudar University	Jan 08, 2024	Criteria: PM2 -
Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Jul 10, 2023	ClinVar contains an entry for this variant (Variation ID: 412018). This sequence change replaces glutamine, which is neutral and polar, with leucine, which is neutral and non-polar, at codon 1823 of the AKAP9 protein (p.Gln1823Leu). This variant is present in population databases (rs147772200, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with AKAP9-related conditions. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

The p.Q1823L variant (also known as c.5468A>T), located in coding exon 22 of the AKAP9 gene, results from an A to T substitution at nucleotide position 5468. The glutamine at codon 1823 is replaced by leucine, an amino acid with dissimilar properties. This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. The evidence for this gene-disease relationship is limited; therefore, the clinical significance of this alteration is unclear. -
