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]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 12, 2023The c.136G>A (p.E46K) alteration is located in exon 1 (coding exon 1) of the PRKACB gene. This alteration results from a G to A substitution at nucleotide position 136, causing the glutamic acid (E) at amino acid position 46 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
