Abstract
We report mutations in SDHAF1, encoding a new LYR-motif protein, in infantile leukoencephalopathy with defective succinate dehydrogenase (SDH, complex II). Disruption of the yeast homolog or expression of variants corresponding to human mutants caused SDH deficiency and failure of OXPHOS-dependent growth, whereas SDH activity and amount were restored in mutant fibroblasts proportionally with re-expression of the wild-type gene. SDHAF1 is the first bona fide SDH assembly factor reported in any organism.| File | Dimensione | Formato | |
