Genes affected

PPP1R3F (HGNC:14944): (protein phosphatase 1 regulatory subunit 3F) This gene encodes a protein that has been identified as one of several type-1 protein phosphatase (PP1) regulatory subunits. One or two of these subunits, together with the well-conserved catalytic subunit, can form the PP1 holoenzyme, where the regulatory subunit functions to regulate substrate specificity and/or targeting to a particular cellular compartment. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2010]

The c.398G>A (p.R133H) alteration is located in exon 1 (coding exon 1) of the PPP1R3F gene. This alteration results from a G to A substitution at nucleotide position 398, causing the arginine (R) at amino acid position 133 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
