Abstract

Significance: Heteroplasmy is the existence of different mtDNA sequences within an individual due to somatic or inherited mutations, and it has been implicated in many mtDNA-related diseases, other diseases, cancer, and aging. However, little is known about how heteroplasmy varies across different tissues from the same individual; here, we analyzed heteroplasmy variation across the entire mtDNA genome in 12 tissues obtained at autopsy from each of 152 individuals. Our results suggest that in addition to neutral processes and negative selection, positive selection has an important influence on heteroplasmy: As individuals get older, specific alleles are selected for at specific nucleotide positions in specific tissues. The functional consequences of these positively selected somatic mutations may play a role in human health and disease.

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.
