The Aberrations section contains reports on chromosomal rearrangements such as translocations, duplications and deficiencies, ring chromosomes, and inversions (including balancers). The system used for assigning symbols to aberrations is described in the Nomenclature guidelines (in the FlyBase Documents directory). Many aberrations are referred to in the literature by symbol(s) that do not correspond to the valid symbol. FlyBase stores these as synonyms.
