New double-mutant fly model of Adrenoleukodystrophy (ALD) "best paradigm to date"

Sivachenko A, Gordon HB, Kimball SS, Gavin EJ, Bonkowsky JL, Letsou A. Neurodegeneration in a Drosophila model of Adrenoleukodystrophy: the roles of the bubblegum and double bubble acyl-CoA synthetases. Dis Model Mech. 2016 Feb 18. pii: dmm.022244. PMID: 26893370.

From the abstract: "Debilitating neurodegenerative conditions with metabolic origins affect millions of individuals worldwide. Still, for most of these neurometabolic disorders ... novel animal models are needed for elucidation of disease pathology and identification of potential therapeutic agents. To date, metabolic neurodegenerative disease has been modeled in animals with only limited success, in part because existing models constitute analyses of single mutants ... We show that the Drosophila bubblegum (bgm) and double bubble (dbb) genes have overlapping functions, and that the consequences of ... double knockout in the fly brain are profound ... providing the best paradigm to date for an animal model of Adrenoleukodystrophy (ALD), a fatal childhood neurodegenerative disease associated with the accumulation of very long chain fatty acids. ... in an extension of our model system to the study of human disease, we describe our identification of a leukodystrophy patient who harbors a rare mutation in a human homologue of Bgm and Dbb: the SLC27a6-encoded very-long-chain acyl-CoA synthetase."
