The deficiencies below have sequenced-defined ends and were generated in a common isogenic background. Information on the majority can be found on the Bloomington Stock Center Deficiency Project (BSC) page. Information on the remaining can be found on the Exelixis, Inc. (Exel) page. See the deficiency information page for an explanation of the columns in this list, references and other useful information. Deficiencies with 'Exel' in the symbol were donated under legal restrictions and require a license for commercial use.

The Exelixis Starter Set contains stocks for generating deletions from Exelixis insertions.
