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 -21 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.51).
BP6
Variant 13-23756612-G-A is Benign according to our data. Variant chr13-23756612-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 770419.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=-0.327 with no splicing effect.
BS1
Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.00777 (1183/152304) while in subpopulation AMR AF= 0.011 (168/15294). AF 95% confidence interval is 0.00963. There are 6 homozygotes in gnomad4. There are 542 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
BS2
High Homozygotes in GnomAd4 at 6 AR gene
