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]

PPP3CC (HGNC:):

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.74).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.436 is higher than 0.05.
