Genes affected

AKAP6 (HGNC:376): (A-kinase anchoring protein 6) 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. The encoded protein is highly expressed in various brain regions and cardiac and skeletal muscle. It is specifically localized to the sarcoplasmic reticulum and nuclear membrane, and is involved in anchoring PKA to the nuclear membrane or sarcoplasmic reticulum. [provided by RefSeq, Jul 2008]

This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 452 of the AKAP6 protein (p.Ala452Thr). This variant is present in population databases (rs772168542, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with AKAP6-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest 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. -
