Genes affected

PRKACB (HGNC:9381): (protein kinase cAMP-activated catalytic subunit beta) The protein encoded by this gene is a member of the serine/threonine protein kinase family. The encoded protein is a catalytic subunit of cAMP (cyclic AMP)-dependent protein kinase, which mediates signalling though cAMP. cAMP signaling is important to a number of processes, including cell proliferaton and differentiation. Multiple alternatively spliced transcript variants encoding distinct isoforms have been observed. [provided by RefSeq, Jul 2014]

Ambry Genetics

Feb 22, 2023

The c.259G>A (p.G87R) alteration is located in exon 3 (coding exon 3) of the PRKACB gene. This alteration results from a G to A substitution at nucleotide position 259, causing the glycine (G) at amino acid position 87 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
