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.445C>T (p.P149S) alteration is located in exon 1 (coding exon 1) of the PPP1R3F gene. This alteration results from a C to T substitution at nucleotide position 445, causing the proline (P) at amino acid position 149 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
