Genes affected

PPP2R5C (HGNC:9311): (protein phosphatase 2 regulatory subunit B'gamma) 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 gamma isoform of the regulatory subunit B56 subfamily. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]

The c.364A>G (p.I122V) alteration is located in exon 4 (coding exon 4) of the PPP2R5C gene. This alteration results from a A to G substitution at nucleotide position 364, causing the isoleucine (I) at amino acid position 122 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
