Genes affected

PPP1R3A (HGNC:9291): (protein phosphatase 1 regulatory subunit 3A) The glycogen-associated form of protein phosphatase-1 (PP1) derived from skeletal muscle is a heterodimer composed of a 37-kD catalytic subunit and a 124-kD targeting and regulatory subunit. This gene encodes the regulatory subunit which binds to muscle glycogen with high affinity, thereby enhancing dephosphorylation of glycogen-bound substrates for PP1 such as glycogen synthase and glycogen phosphorylase kinase.

PPP1R3A Gene-Disease associations (from GenCC):

• diabetes mellitus, noninsulin-dependent

  Inheritance: Unknown Classification: LIMITED, NO_KNOWN Submitted by: Labcorp Genetics (formerly Invitae), Ambry Genetics

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-1.01).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.698 is higher than 0.05.
