Genes affected

PRKAR1B (HGNC:9390): (protein kinase cAMP-dependent type I regulatory subunit beta) The protein encoded by this gene is a regulatory subunit of cyclic AMP-dependent protein kinase A (PKA), which is involved in the signaling pathway of the second messenger cAMP. Two regulatory and two catalytic subunits form the PKA holoenzyme, disbands after cAMP binding. The holoenzyme is involved in many cellular events, including ion transport, metabolism, and transcription. Several transcript variants encoding the same protein have been found for this gene.

The c.1129A>G (p.I377V) alteration is located in exon 11 (coding exon 10) of the PRKAR1B gene. This alteration results from a A to G substitution at nucleotide position 1129, causing the isoleucine (I) at amino acid position 377 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
