Is an ortholog of human SDHA (succinate dehydrogenase complex flavoprotein subunit A). Is predicted to have electron transfer activity\; flavin adenine dinucleotide binding activity\; and succinate dehydrogenase (ubiquinone) activity. Human ortholog(s) of this gene are implicated in several diseases, including Leigh disease\; dilated cardiomyopathy 1GG\; and mitochondrial complex II deficiency.
