Genes affected

PPIL2 (HGNC:9261): (peptidylprolyl isomerase like 2) This gene is a member of the cyclophilin family of peptidylprolyl isomerases. The cyclophilins are a highly conserved ubiquitous family, members of which play an important role in protein folding, immunosuppression by cyclosporin A, and infection of HIV-1 virions. This protein interacts with the proteinase inhibitor eglin c and is localized in the nucleus. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Dec 2015]

The c.482C>T (p.P161L) alteration is located in exon 9 (coding exon 9) of the PPIL2 gene. This alteration results from a C to T substitution at nucleotide position 482, causing the proline (P) at amino acid position 161 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
