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

PRKACB-related disorder Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingPreventionGenetics, part of Exact SciencesDec 19, 2022The PRKACB c.180C>A variant is predicted to result in the amino acid substitution p.Asp60Glu. To our knowledge, this variant has not been reported in the literature or in a large population database (http://gnomad.broadinstitute.org), indicating this variant is rare. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
