Part of the research was to analyze cerebral deletion levels in the temporal and frontal lobes. Research hypothesis: HD patients have significantly higher mtDNA deletionlevels than agematched controls in the frontal and temporal lobes of the cortex. To test the hypothesis, the amount of mtDNA deletion in 22 HD patients brains was examined by serial dilution-polymerase chain reaction (PCR) and compared the results with mtDNA deletion levels in 25 aged match .....
