NDUFS8 (NADH:ubiquinone oxidoreductase core subunit S8) is named by 1 disorder entry.
ai-gene-review gives NDUFS8's core molecular functions as 4 iron, 4 sulfur cluster binding; and NADH dehydrogenase (ubiquinone) activity, acting in mitochondrial electron transport, NADH to ubiquinone. The upstream review describes NDUFS8 as a catalytic core subunit of the complex I peripheral arm that carries two of the enzyme's [4Fe-4S] clusters.
The one entry naming NDUFS8, Mitochondrial Complex I Deficiency, Nuclear Type 2, types it as causative and records the variants as germline. The gene sits on the node NDUFS8 Loss of Function, and nodes naming it conform to the module complex_i_deficiency.
No process term on the KB's NDUFS8 nodes matches an ai-gene-review core process by exact identifier (0 shared); the entry records the gene's normal function as molecular-function and assembly terms on the nodes downstream of the gene node instead.
ClinGen classifies NDUFS8 for 2 diseases. The one with no dismech entry is mitochondrial disease, and the dismech entries matched to a ClinGen disease for NDUFS8 that do not type the gene are Leber-like Hereditary Optic Neuropathy, Autosomal Recessive 1; and Leigh Syndrome.
Underlined values are claims re-computed from the knowledge base each time this page is built. The tables below are the source of truth.
ai-gene-review has this gene at status INITIALIZED; the description is shown only once the review is complete. Read the draft upstream.
Relationship is the entry's genetic[].relationship_type. untyped means the entry has a genetic record for the gene but does not type it; its free-text association is shown instead.
| Disorder | Relationship | Where the gene appears |

An entry matches when ClinGen's MONDO disease is the entry's own disease term, a subtype term, or an exact-match mapping. An amber status marks an entry ClinGen supports the gene for (Definitive, Strong or Moderate) whose own record does not type it. A Limited, Disputed or Refuted tier on such an entry is not a gap.
