Genes affected

PPP1R3C (HGNC:9293): (protein phosphatase 1 regulatory subunit 3C) This gene encodes a carbohydrate binding protein that is a subunit of the protein phosphatase 1 (PP1) complex. PP1 catalyzes reversible protein phosphorylation, which is important in a wide range of cellular activities. The encoded protein affects glycogen biosynthesis by activating glycogen synthase and limiting glycogen breakdown by reducing glycogen phosphorylase activity. DNA hypermethylation of this gene has been found in colorectal cancer patients. The encoded protein also interacts with the laforin protein, which is a protein tyrosine phosphatase implicated in Lafora disease. [provided by RefSeq, Sep 2016]

The c.932A>G (p.E311G) alteration is located in exon 1 (coding exon 1) of the PPP1R3C gene. This alteration results from a A to G substitution at nucleotide position 932, causing the glutamic acid (E) at amino acid position 311 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
