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.3193G>A (p.E1065K) alteration is located in exon 4 (coding exon 4) of the PPP1R3A gene. This alteration results from a G to A substitution at nucleotide position 3193, causing the glutamic acid (E) at amino acid position 1065 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
