Extra information provided by this PSP
Original uncertainty examples What causes the mutation? Can the mutation occur at any time or is it historical? ~ what causes sporadic DNA mutations? why do they happen? are you sure that they are sporadice? how do you know? ~ In [name]'s case her disease is spontaneous rather than genetic, more research into why it happened. ~ Why are there so many different mutations of the disorder. What triggers the mutations? Why do the mitochondria mutate? ~ What would have caused my mothers gene to mutate to cause the disease. ~ Is the fault on the gene a spontaneous mutation? ~ I didn’t inherit this disease. So what caused it?
