Summary

Story summary

The study analyzed 37 patients with the m.3243 A > G mitochondrial DNA variant to identify complications including hearing loss.
Hearing loss often emerges after language acquisition, with a median onset age of 25 years.
Flat-type hearing loss configurations are more common in older patients.
Lower body mass index links to multiple organ complications, highlighting disease complexity.
Therapies such as L-arginine show promise, but more research is needed on heteroplasmy.
