Genes affected

PPP6R2 (HGNC:19253): (protein phosphatase 6 regulatory subunit 2) The protein encoded by this gene is a regulatory protein for the protein phosphatase-6 catalytic subunit. Together, these proteins act as a significant T-loop phosphatase for Aurora A, an essential mitotic kinase. Loss of function of either the regulatory or catalytic subunit of protein phosphatase-6 interferes with spindle formation and chromosome alignment. [provided by RefSeq, May 2017]

The c.2852A>G (p.E951G) alteration is located in exon 24 (coding exon 22) of the PPP6R2 gene. This alteration results from a A to G substitution at nucleotide position 2852, causing the glutamic acid (E) at amino acid position 951 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
