Genes affected
NDUFAF2 (HGNC:28086): (NADH:ubiquinone oxidoreductase complex assembly factor 2) NADH:ubiquinone oxidoreductase (complex I) catalyzes the transfer of electrons from NADH to ubiquinone (coenzyme Q) in the first step of the mitochondrial respiratory chain, resulting in the translocation of protons across the inner mitochondrial membrane. This gene encodes a complex I assembly factor. Mutations in this gene cause progressive encephalopathy resulting from mitochondrial complex I deficiency. [provided by RefSeq, Jul 2008]

Likely pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jun 29, 2023 | Disruption of the initiator codon has been observed in individuals with mitochondrial complex I deficiency (PMID: 18180188, 25590979). This variant is not present in population databases (gnomAD no frequency). This sequence change affects the initiator methionine of the NDUFAF2 mRNA. The next in-frame methionine is located at codon 85. ClinVar contains an entry for this variant (Variation ID: 496596). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. - |
