OrganismDrosophila melanogaster
Aging PhenotypeShortened life-span
Allele TypeUnknown
DescriptionDrop-dead mutants die early in adult life, displaying gross neuropathological lesions in the brain. (Buchanan and Benzer, 1993) The survival curve of drop-dead mutants is four to five times shorter than, but otherwise similar in shape to, wild-type. In flies, some genes show characteristic temporal changes in expression levels with age. Drop-dead mutants have been shown to exhibit temporal compression of this time course in the three genes tested, suggesting that drop-dead mutations may cause an acceleration of the normal aging process. (Rogina et al., 1997)
Gene FunctionUnknown.
Other PhenotypesFlies begin staggering at various times early in adult life, then die. (Buchanan, 1993)
