Heteroplasmy analysis in the Polish patients with 11778A mutation responsible for Leber hereditary optic neuropathy.

Languages of publication
We have analysed the heteroplasmy level in 11 individuals from 3 families harbouring the mitochondrial 11778A mutation responsible for Leber hereditary optic neuropathy using last cycle hot PCR. The mutation level exceeded 90% both in affected and in unaffected individuals. We also checked whether any of the families belonged to the J haplogroup of mitochondrial DNA and obtained a negative result.
