Children born to women who carry pathogenic variants in mitochondrial DNA (mtDNA) are at risk for a range of clinical syndromes collectively known as mtDNA disease. Mitochondrial donation by ...

Researchers from Karolinska Institutet have discovered how mammalian cells prevent the gradual buildup of harmful mutations in mitochondrial DNA, the small but vital genome that powers every cell. The ...

NMAFREF copy purchased with funds from the S. Dillon Ripley Endowment. Part one: Getting started -- Genetic genealogy basics -- Common misconceptions -- Ethics and genetic genealogy -- Part two: ...

Researchers identified a new, sticky form of mitochondrial DNA damage that builds up at dramatically higher levels than in nuclear DNA. These lesions disrupt energy production and activate ...

Maintaining mitochondrial DNA (mtDNA) integrity is crucial for cardiomyocyte function, and its disruption plays a significant role in ischemia/reperfusion (I/R) injury. This review sheds light on the ...

Methods We offered mitochondrial donation (by pronuclear transfer) or preimplantation genetic testing (PGT) to a series of women with pathogenic mtDNA variants who sought to reduce the transmission of ...
