Genes affected
IMMP1L (HGNC:26317): (inner mitochondrial membrane peptidase subunit 1) The mitochondrial inner membrane peptidase (IMP) complex generates mature, active proteins in the mitochondrial intermembrane space by proteolytically removing the mitochondrial targeting presequence of nuclear-encoded proteins. IMP1 and IMP2 (IMMP2L; MIM 605977) are the catalytic subunits of the IMP complex (Burri et al., 2005 [PubMed 15814844]).[supplied by OMIM, Sep 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 14, 2023The c.88G>A (p.V30I) alteration is located in exon 3 (coding exon 1) of the IMMP1L gene. This alteration results from a G to A substitution at nucleotide position 88, causing the valine (V) at amino acid position 30 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
