Genes affected

PPIF (HGNC:9259): (peptidylprolyl isomerase F) 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 is part of the mitochondrial permeability transition pore in the inner mitochondrial membrane. Activation of this pore is thought to be involved in the induction of apoptotic and necrotic cell death. [provided by RefSeq, Jul 2008]

The c.478A>G (p.K160E) alteration is located in exon 5 (coding exon 5) of the PPIF gene. This alteration results from a A to G substitution at nucleotide position 478, causing the lysine (K) at amino acid position 160 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
