Different views on what is important
Advances relevant to…
• Families with young children
– Genetic advances offer reproductive
options
• Older people with established disease
– A new drug to be trialled
Genetic advances offer
reproductive options
Predicting recurrence is DIFFICULT
Child’s severity reflects mtDNA
composition in embryos and oocytes
And in human“control”
MtDNA flags show that eggs are already decided

Sampling earlystages is accurate
? CVSSampling laterstages varies
Reproductive options now available

Reproductive options now available:
Mitochondrial donation

Cardiolipin is an important building block for
keeping the production line connected
ROS damage cardiolipin and hence the
mitochondrial production line for energy
Bendavia protectscardiolipin
BUT: it needs to be injected
Studies to start soon but entry criteria will be strict
