Mitochondrial DNA haplogroup distribution within Leber hereditary optic neuropathy pedigrees.
L eber hereditary optic neuropathy (LHON; OMIM #535000) is a mitochondrial genetic disease that causes blindness in young adults, with an estimated minimum prevalence of 3.2 per 100 000 in the north east of England. It classically presents as bilateral subacute loss of central vision due to the focal neurodegeneration of the retinal ganglion cell layer. Over 95% of cases are principally due to ...
متن کاملLeber hereditary optic neuropathy.
BACKGROUND Leber hereditary optic neuropathy (LHON) is a cause of inherited blindness that typically presents with bilateral, painless, subacute visual failure in young adult males. Males are about four times more likely to be affected than females and 95% of LHON carriers become affected before the age of 50. Affected patients may have characteristic ocular fundal appearances and have evidence...
متن کاملLeber hereditary optic neuropathy
Leber hereditary optic neuropathy is a maternally inherited bilateral optic neuropathy that typically affects teenage males with acute vision loss first in one eye and then the other within days or weeks. The etiology involves a point mutation in the mitochondrial DNA at 1 of 3 main loci: 11778, 14484, or 3460. There are some distinctive changes in the ocular fundus appearance at various stages...
متن کاملPhylogenetic analysis of the mitochondrial genomes from Leber hereditary optic neuropathy pedigrees.
The nucleotide sequences of the mitochondrial genomes from patients with Leber hereditary optic neuropathy (LHON) were used for phylogenetic analysis to study the origin and population history of pathogenic mitochondrial mutations. Sequences of both the coding region (8300 bp) and the more rapidly evolving noncoding control region (1300 bp) were analyzed. Patients with the primary LHON mutation...
