Genes affected

PPP5C (HGNC:9322): (protein phosphatase 5 catalytic subunit) This gene encodes a serine/threonine phosphatase which is a member of the protein phosphatase catalytic subunit family. Proteins in this family participate in pathways regulated by reversible phosphorylation at serine and threonine residues; many of these pathways are involved in the regulation of cell growth and differentiation. The product of this gene has been shown to participate in signaling pathways in response to hormones or cellular stress, and elevated levels of this protein may be associated with breast cancer development. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2011]

The c.129C>G (p.D43E) alteration is located in exon 2 (coding exon 2) of the PPP5C gene. This alteration results from a C to G substitution at nucleotide position 129, causing the aspartic acid (D) at amino acid position 43 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
