Genes affected

PPP1CC (HGNC:9283): (protein phosphatase 1 catalytic subunit gamma) The protein encoded by this gene belongs to the protein phosphatase family, PP1 subfamily. PP1 is an ubiquitous serine/threonine phosphatase that regulates many cellular processes, including cell division. It is expressed in mammalian cells as three closely related isoforms, alpha, beta/delta and gamma, which have distinct localization patterns. This gene encodes the gamma isozyme. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2011]

The c.140T>G (p.L47R) alteration is located in exon 2 (coding exon 2) of the PPP1CC gene. This alteration results from a T to G substitution at nucleotide position 140, causing the leucine (L) at amino acid position 47 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
