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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 26, 2023The c.379G>A (p.A127T) alteration is located in exon 7 (coding exon 7) of the PPIL2 gene. This alteration results from a G to A substitution at nucleotide position 379, causing the alanine (A) at amino acid position 127 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
