The Claim
Genetically predicted acceleration of HannumAge is associated with a 22.5% reduced risk of early-onset myasthenia gravis in individuals of European ancestry.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People with genetic patterns that predict faster biological aging, as measured by the HannumAge epigenetic clock, have a 22.5% lower risk of developing early-onset myasthenia gravis compared to those with slower biological aging, based on data from individuals of European ancestry.
See the scientific wording
Genetically predicted acceleration of HannumAge, an epigenetic clock measuring biological aging, is associated with a 22.5% reduced risk of early-onset myasthenia gravis (EOMG) in individuals of European ancestry, suggesting that a younger biological age may increase susceptibility to this autoimmune subtype, potentially due to preserved thymic function and heightened immune reactivity.
A younger biological age keeps the thymus active longer, which trains more immune cells to attack the body’s own acetylcholine receptors, triggering muscle weakness. The resulting inflammation changes DNA methylation patterns, making the body appear older over time.
What the research says
1 studyThe study used Mendelian randomization to link genetic variants associated with HannumAge to EOMG risk, finding a statistically significant inverse association (OR=0.775) that survived FDR correction. This suggests biological youth, not chronological youth, correlates with higher EOMG risk.
