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]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.56).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.347 is higher than 0.05.
