RESUMO
Leber's hereditary optic neuropathy (LHON) is a maternally inherited degenerative disorder characterised by an acute or subacute optic nerve degeneration resulting in visual failure. Mitochondrial DNA mutations have been reported and a nuclear modifier gene(s) on the X chromosome is thought to play an important role in the onset of this disorder. We analysed a LHON family with a novel and more accurate approach using 27 X chromosomal microsatellite markers. Meiotic breakpoint mapping and two point lod score did not point to any particular area on the X chromosome which might contain the X susceptibility locus.
