Genes affected

IMMP2L (HGNC:14598): (inner mitochondrial membrane peptidase subunit 2) This gene encodes a protein involved in processing the signal peptide sequences used to direct mitochondrial proteins to the mitochondria. The encoded protein resides in the mitochondria and is one of the necessary proteins for the catalytic activity of the mitochondrial inner membrane peptidase (IMP) complex. Two variants that encode the same protein have been described for this gene. [provided by RefSeq, Sep 2011]

The c.344G>A (p.R115H) alteration is located in exon 5 (coding exon 4) of the IMMP2L gene. This alteration results from a G to A substitution at nucleotide position 344, causing the arginine (R) at amino acid position 115 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
