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.

The c.3026G>C (p.G1009A) alteration is located in exon 4 (coding exon 4) of the PPP1R3A gene. This alteration results from a G to C substitution at nucleotide position 3026, causing the glycine (G) at amino acid position 1009 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
