Genes affected

PPP2R5B (HGNC:9310): (protein phosphatase 2 regulatory subunit B'beta) The product of this gene belongs to the phosphatase 2A regulatory subunit B family. Protein phosphatase 2A is one of the four major Ser/Thr phosphatases, and it is implicated in the negative control of cell growth and division. It consists of a common heteromeric core enzyme, which is composed of a catalytic subunit and a constant regulatory subunit, that associates with a variety of regulatory subunits. The B regulatory subunit might modulate substrate selectivity and catalytic activity. This gene encodes a beta isoform of the regulatory subunit B56 subfamily. [provided by RefSeq, Jul 2008]

The c.127C>T (p.R43C) alteration is located in exon 2 (coding exon 1) of the PPP2R5B gene. This alteration results from a C to T substitution at nucleotide position 127, causing the arginine (R) at amino acid position 43 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
