Rh. Triepels et al., Leigh syndrome associated with a mutation in the NDUFS7 (PSST) nuclear encoded subunit of complex I, ANN NEUROL, 45(6), 1999, pp. 787-790
Leigh syndrome is the phenotypical expression of a genetically heterogeneou
s cluster of disorders, with pyruvate dehydrogenase complex deficiency and
respiratory chain disorders as the main biochemical causes. We report the f
irst missense mutation within the nuclear encoded complex I subunit, NDUFS7
, in 2 siblings with neuropathologically proven complex I-deficient Leigh s
yndrome.
