Genes affected

PPIE (HGNC:9258): (peptidylprolyl isomerase E) The protein encoded by this gene is a member of the peptidyl-prolyl cis-trans isomerase (PPIase) family. PPIases catalyze the cis-trans isomerization of proline imidic peptide bonds in oligopeptides and accelerate the folding of proteins. This protein contains a highly conserved cyclophilin (CYP) domain as well as an RNA-binding domain. It was shown to possess PPIase and protein folding activities, and it also exhibits RNA-binding activity. Alternative splicing results in multiple transcript variants. A related pseudogene, which is also located on chromosome 1, has been identified. [provided by RefSeq, Aug 2010]

Collection Method: clinical testing

The c.755G>A (p.C252Y) alteration is located in exon 9 (coding exon 9) of the PPIE gene. This alteration results from a G to A substitution at nucleotide position 755, causing the cysteine (C) at amino acid position 252 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
