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.2585C>T (p.T862M) alteration is located in exon 23 (coding exon 22) of the PPP6R1 gene. This alteration results from a C to T substitution at nucleotide position 2585, causing the threonine (T) at amino acid position 862 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
