Genes affected

AKAP8 (HGNC:378): (A-kinase anchoring protein 8) This gene encodes a member of the A-kinase anchor protein family. A-kinase anchor proteins are scaffold proteins that contain a binding domain for the RI/RII subunit of protein kinase A (PKA) and recruit PKA and other signaling molecules to specific subcellular locations. This gene encodes a nuclear A-kinase anchor protein that binds to the RII alpha subunit of PKA and may play a role in chromosome condensation during mitosis by targeting PKA and the condensin complex to chromatin. A pseudogene of this gene is located on the short arm of chromosome 9. [provided by RefSeq, May 2011]

The c.1751C>A (p.A584E) alteration is located in exon 14 (coding exon 14) of the AKAP8 gene. This alteration results from a C to A substitution at nucleotide position 1751, causing the alanine (A) at amino acid position 584 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
