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 PPP5C c.46dupC variant is predicted to result in a frameshift and premature protein termination (p.Arg16Profs*7). To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0069% of alleles in individuals of European (Non-Finnish) descent in gnomAD; however, this data may not be reliable (http://gnomad.broadinstitute.org/variant/19-46850392-G-GC). Loss-of-function has not been established as a disease mechanism for this gene, and therefore the clinical significance of this variant is currently uncertain due to the absence of conclusive functional and genetic evidence. -
