Genes affected

PRKACG (HGNC:9382): (protein kinase cAMP-activated catalytic subunit gamma) Cyclic AMP-dependent protein kinase (PKA) consists of two catalytic subunits and a regulatory subunit dimer. This gene encodes the gamma form of its catalytic subunit. The gene is intronless and is thought to be a retrotransposon derived from the gene for the alpha form of the PKA catalytic subunit.

Collection Method: clinical testing

The c.721G>A (p.A241T) alteration is located in exon 1 (coding exon 1) of the PRKACG gene. This alteration results from a G to A substitution at nucleotide position 721, causing the alanine (A) at amino acid position 241 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
