Genes affected

MIPEP (HGNC:7104): (mitochondrial intermediate peptidase) The product of this gene performs the final step in processing a specific class of nuclear-encoded proteins targeted to the mitochondrial matrix or inner membrane. This protein is primarily involved in the maturation of oxidative phosphorylation (OXPHOS)-related proteins. This gene may contribute to the functional effects of frataxin deficiency and the clinical manifestations of Friedreich ataxia. [provided by RefSeq, Jul 2008]

The c.2137G>A (p.E713K) alteration is located in exon 19 (coding exon 19) of the MIPEP gene. This alteration results from a G to A substitution at nucleotide position 2137, causing the glutamic acid (E) at amino acid position 713 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
