Previous symbols: MTND1. Aliases: ND1, NAD1.
MT-ND1 (mitochondrially encoded NADH:ubiquinone oxidoreductase core subunit 1) is named by 3 disorder entries. It is a mitochondrial-DNA-encoded core subunit of the membrane arm of respiratory complex I.
The pinned ai-gene-review snapshot that the ingest layer reads has no core functions for MT-ND1 (0 terms). An upstream review of the gene is being added or updated.
The entries that type MT-ND1 as causative are Leber Hereditary Optic Neuropathy; MELAS Syndrome. Leber Hereditary Optic Neuropathy records the variants as germline and places the gene on the node Complex I Subunit Missense Mutation. MELAS Syndrome records them as germline and places the gene on Complex I structural subunit defect. Leber Optic Atrophy and Dystonia names MT-ND1 on the node but has no genetic record for it (Leber Optic Atrophy and Dystonia).
ClinGen classifies MT-ND1 for 2 diseases, and rates it definitive for Leigh syndrome. The entries ClinGen classifies it for whose own records do not type it are Leber-like Hereditary Optic Neuropathy, Autosomal Recessive 1; Leigh Syndrome. The ClinGen disease with no matching dismech entry is mitochondrial disease. The KB's nodes naming MT-ND1 carry no GO process annotations (0 terms), so the KB and ai-gene-review share 0 GO process terms.
Underlined values are claims re-computed from the knowledge base each time this page is built. The tables below are the source of truth.
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.

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.
