Genes affected

PPP1R3B (HGNC:14942): (protein phosphatase 1 regulatory subunit 3B) This gene encodes the catalytic subunit of the serine/theonine phosphatase, protein phosphatase-1. The encoded protein is expressed in liver and skeletal muscle tissue and may be involved in regulating glycogen synthesis in these tissues. This gene may be a involved in type 2 diabetes and maturity-onset diabetes of the young. Alternate splicing results in multiple transcript variants that encode the same protein.[provided by RefSeq, Jan 2011]

The c.836A>G (p.E279G) alteration is located in exon 2 (coding exon 1) of the PPP1R3B gene. This alteration results from a A to G substitution at nucleotide position 836, causing the glutamic acid (E) at amino acid position 279 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
