SIB Swiss Institute of Bioinformatics

Significance: Likely pathogenic

Review Status: criteria provided, single submitter

Collection Method: curation

This variant is interpreted as a Likely pathogenic for Mitochondrial complex I deficiency, nuclear type 8, autosomal recessive. The following ACMG Tag(s) were applied: PM2 : Absent from controls (or at extremely low frequency if recessive) in Exome Sequencing Project, 1000 Genomes Project, or Exome Aggregation Consortium. PP3 : Multiple lines of computational evidence support a deleterious effect on the gene or gene product. PP1 : Cosegregation with disease in multiple affected family members in a gene definitively known to cause the disease (PMID:14729820). PM3 : For recessive disorders, detected in trans with a pathogenic variant (PMID:14729820). -
