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.77C>T (p.T26I) 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 77, causing the threonine (T) at amino acid position 26 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
