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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 18, 2023The c.523C>T (p.P175S) alteration is located in exon 5 (coding exon 3) of the PPP6R2 gene. This alteration results from a C to T substitution at nucleotide position 523, causing the proline (P) at amino acid position 175 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
