Genes affected

PPID (HGNC:9257): (peptidylprolyl isomerase D) 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 has been shown to possess PPIase activity and, similar to other family members, can bind to the immunosuppressant cyclosporin A. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.605A>C (p.H202P) alteration is located in exon 5 (coding exon 5) of the PPID gene. This alteration results from a A to C substitution at nucleotide position 605, causing the histidine (H) at amino acid position 202 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
