Mitochondrial complex I deficiency, nuclear type 8 Pathogenic:2
Jan 23, 2019
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). PS3 : Well-established functional studies show a deleterious effect (PMID:22499348). -

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

For these reasons, this variant has been classified as Pathogenic. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt NDUFS3 protein function. ClinVar contains an entry for this variant (Variation ID: 6020). This missense change has been observed in individuals with mitochondrial complex I deficiency (PMID: 14729820, 22499348, 30140060). It has also been observed to segregate with disease in related individuals. This variant is present in population databases (rs104894270, gnomAD 0.006%). This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 199 of the NDUFS3 protein (p.Arg199Trp). -
