Genes affected

PPP6R1 (HGNC:29195): (protein phosphatase 6 regulatory subunit 1) Protein phosphatase regulatory subunits, such as SAPS1, modulate the activity of protein phosphatase catalytic subunits by restricting substrate specificity, recruiting substrates, and determining the intracellular localization of the holoenzyme. SAPS1 is a regulatory subunit for the protein phosphatase-6 catalytic subunit (PPP6C; MIM 612725) (Stefansson and Brautigan, 2006 [PubMed 16769727]).[supplied by OMIM, Nov 2010]

The c.2327C>G (p.P776R) alteration is located in exon 20 (coding exon 19) of the PPP6R1 gene. This alteration results from a C to G substitution at nucleotide position 2327, causing the proline (P) at amino acid position 776 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
