BACKGROUND: Despite evidence supporting an involvement of mitochondrial
dysfunction in the pathogenesis of some neurodegenerative disorders, there are
inconsistent findings concerning mitochondrial haplogroups and their association
to neurodegenerative disorders, including idiopathic Parkinson's disease (PD).
METHODS: To test this hypothesis for the Greek-Cypriot population, a cohort of
230 PD patients and 457 healthy matched controls were recruited. Mitochondrial
haplogroup distributions for cases and controls were determined. Association
tests were carried out between mitochondrial haplogroups and PD. RESULTS:
Mitochondrial haplogroup U was associated with a reduced PD risk in the Cypriot
population. After pooling mitochondrial haplogroups together into haplogroup
clusters and superclusters, association tests demonstrated a significantly
protective effect of mitochondrial haplogroup cluster N (xR) and supercluster LMN
for PD risk only in females. In addition, for female PD cases belonging to UKJT
and R (xH, xUKJT) haplogroup, the odds of having a later age of onset of PD were
13 and 15 times respectively higher than the odds for female cases with an H
haplogroup. CONCLUSION: Statistically significant associations regarding PD risk
and PD age of onset were mostly detected for females thus suggesting that gender
is a risk modifier between mitochondrial haplogroups and PD status / PD age of
onset. The biological mechanisms behind this gender specificity remain to be
determined.
