Genes affected

PPP3CC (HGNC:9316): (protein phosphatase 3 catalytic subunit gamma) Calcineurin is a calcium-dependent, calmodulin-stimulated protein phosphatase involved in the downstream regulation of dopaminergic signal transduction. Calcineurin is composed of a regulatory subunit and a catalytic subunit. The protein encoded by this gene represents one of the regulatory subunits that has been found for calcineurin. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2011]

The c.134A>G (p.H45R) alteration is located in exon 2 (coding exon 2) of the PPP3CC gene. This alteration results from a A to G substitution at nucleotide position 134, causing the histidine (H) at amino acid position 45 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
