NADH dehydrogenase ubiquinone flavoprotein 2 (NDUFV2), encoding a subunit of mitochondrial complex I, is a candidate gene for several neuronal diseases; schizophrenia, bipolar disorder and Parkinson disease (PD).
The NADH-ubiquinone oxidoreductase flavoprotein gene (NDUFV2), which encodes a 24 kD mitochondrial complex I subunit, has been reported to be positively associated with schizophrenia and bipolar disorder in different populations.
To study the role of NDUFV2 in bipolar disorder in the Chinese population, 506 unrelated bipolar patients and 507 unrelated controls of Chinese Han origin were recruited.
mRNA and protein levels of complex I subunits NDUFV1, NDUFV2 and NADUFS1, were assessed in striatal and lateral cerebellar hemisphere postmortem specimens and analyzed together with our previous data from prefrontal and parieto-occipital cortices specimens of patients with schizophrenia, bipolar disorder, major depression and healthy subjects.
