Genes affected
PPP1R1C (HGNC:14940): (protein phosphatase 1 regulatory inhibitor subunit 1C) Protein phosphatase-1 (PP1) is a major serine/threonine phosphatase that regulates a variety of cellular functions. PP1 consists of a catalytic subunit (see PPP1CA; MIM 176875) and regulatory subunits that determine the subcellular localization of PP1 or regulate its function. PPP1R1C belongs to a group of PP1 inhibitory subunits that are themselves regulated by phosphorylation (Wang et al., 2008 [PubMed 18310074]).[supplied by OMIM, Feb 2010]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 13, 2023The c.37G>A (p.V13M) alteration is located in exon 1 (coding exon 1) of the PPP1R1C gene. This alteration results from a G to A substitution at nucleotide position 37, causing the valine (V) at amino acid position 13 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
