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.511A>G (p.N171D) alteration is located in exon 9 (coding exon 9) of the PPIL2 gene. This alteration results from a A to G substitution at nucleotide position 511, causing the asparagine (N) at amino acid position 171 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
