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

Sep 01, 2021

The c.160G>A (p.A54T) 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 160, causing the alanine (A) at amino acid position 54 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
