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]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -13 ACMG points.

PP3
Multiple lines of computational evidence support a deleterious effect 6: AlphaMissense, Cadd, Eigen, FATHMM_MKL, MutationAssessor, phyloP100way_vertebrate [when max_spliceai, M_CAP, MetaRNN, MutationTaster was below the threshold]
BP4
Computational evidence support a benign effect (MetaRNN=0.09164819).
BP6
Variant 13-23760142-C-T is Benign according to our data. Variant chr13-23760142-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 757963.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BS1
Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.000322 (49/152274) while in subpopulation SAS AF= 0.000414 (2/4828). AF 95% confidence interval is 0.00017. There are 1 homozygotes in gnomad4. There are 30 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.

Significance: Likely benign
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
