Genomic instability
Hallmark of aging61 papers13 findings
Human cohorts and cell models link genomic instability to age, genetic variants, and somatic mutations, whilst mouse studies show that gene knockouts induce it. Reviews describe transposable element reactivation, oxidative stress, and associations with senescence and atherosclerosis.

Human neurons from frontotemporal lobar degeneration patients showed ultra-low-frequency TARDBP variants that were less abundant in individuals who died at older ages.
Human neurons accumulate far more mutations over lifespan than shorter-lived mammals
Cortical neurons gain mutations at similar yearly rates across six species, leaving aged humans with uniquely high mutational burdens and transcriptomic dysregulation.
