Mitochondrial sequence variation in African-American primary open-angle glaucoma patients.

ABSTRACT: Primary open-angle glaucoma (POAG) is a major cause of blindness and results from irreversible retinal ganglion cell damage and optic nerve degeneration. In the United States, POAG is most prevalent in African-Americans. Mitochondrial genetics and dysfunction have been implicated in POAG, and potentially pathogenic sequence variations, in particular novel transversional base substitutions, are reportedly common in mitochondrial genomes (mtDNA) from POAG patient blood. The purpose of this study was to ascertain the spectrum of sequence variation in mtDNA from African-American POAG patients and determine whether novel nonsynonymous, transversional or other potentially pathogenic sequence variations are observed more commonly in POAG cases than controls. mtDNA from African-American POAG cases
