Human mitochondrial DNA: roles of inherited and somatic mutations

Open access
Schon, Eric A., DiMauro, Salvatore, Hirano, Michio·2012·Nature Reviews Genetics

Abstract

Mutations in the human mitochondrial genome are known to cause an array of diverse disorders, most of which are maternally inherited, and all of which are associated with defects in oxidative energy metabolism. It is now emerging that somatic mutations in mitochondrial DNA (mtDNA) are also linked to other complex traits, including neurodegenerative diseases, ageing and cancer. Here we discuss insights into the roles of mtDNA mutations in a wide variety of diseases, highlighting the interesting genetic characteristics of the mitochondrial genome and challenges in studying its contribution to pathogenesis.

  • Mitochondrial haplogroups carrying pathogenic SNPs can contribute to metabolic, late-onset neurodegenerative and autoimmune diseases.

    “MtDNA haplogroups with pathogenic SNPs can contribute to metabolic, late-onset neurodegenerative diseases and autoimmune diseases through various mechanisms32,33”

    From The role of mitochondria in rheumatic diseases (2022) · cites this paper as [32]

    The 'Mitochondrial haplotypes as modifiers' section says pathogenic mtDNA mutations can cause diabetes and describes a haplogroup modifying the effects of an optic-neuropathy mutation. But 'Susceptibility to complex disorders' calls links between haplogroups and metabolic or neurodegenerative disorders highly controversial and concludes that the evidence is too weak to establish a contribution. The paper mentions an autoimmune response to mitochondrial dysfunction, not autoimmune disease caused by haplogroups carrying pathogenic SNPs. (LLM, conf=0.88)

  • Mitochondrial mutations are increasingly implicated in mitochondrial malfunction during aging.

    “The mitochondrial genome has a high mutation rate, and mitochondrial mutations are increasingly implicated in mitochondrial malfunction during aging(Schon et al., 2012; Sevini et al., 2014).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
