Genes affected

PPP1R14C (HGNC:14952): (protein phosphatase 1 regulatory inhibitor subunit 14C) The degree of protein phosphorylation is regulated by a balance of protein kinase and phosphatase activities. Protein phosphatase-1 (PP1; see MIM 176875) is a signal-transducing phosphatase that influences neuronal activity, protein synthesis, metabolism, muscle contraction, and cell division. PPP1R14C is an inhibitor of PP1 (Liu et al., 2002 [PubMed 11812771]).[supplied by OMIM, Feb 2010]

Ambry Genetics

Dec 27, 2023

The c.148G>A (p.V50M) alteration is located in exon 1 (coding exon 1) of the PPP1R14C gene. This alteration results from a G to A substitution at nucleotide position 148, causing the valine (V) at amino acid position 50 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
