Genes affected

PPP1R16B (HGNC:15850): (protein phosphatase 1 regulatory subunit 16B) The protein encoded by this gene is membrane-associated and contains five ankyrin repeats, a protein phosphatase-1-interacting domain, and a carboxy-terminal CAAX box domain. Synthesis of the encoded protein is inhibited by transforming growth factor beta-1. The protein may bind to the membrane through its CAAX box domain and may act as a signaling molecule through interaction with protein phosphatase-1. Alternative splicing results in multiple transcript variants encoding different isoforms that may undergo similar processing to generate mature protein. [provided by RefSeq, Sep 2015]

The c.433G>A (p.G145S) alteration is located in exon 4 (coding exon 3) of the PPP1R16B gene. This alteration results from a G to A substitution at nucleotide position 433, causing the glycine (G) at amino acid position 145 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
