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]

ACMG classification

Verdict is Likely_benign. Variant got -6 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.76).
• BP6: Variant 5-60945223-G-A is Benign according to our data. Variant chr5-60945223-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 380185.Status of the report is criteria_provided_single_submitter, 1 stars.
