Abstract: Compositions and methods for the diagnosis and treatment of a cancer that is resistant to at least one anaplastic lymphoma kinase (ALK) kinase inhibitor are provided herein. The present invention is based on the discovery of mutations within ALK that confer resistance to at least one ALK kinase inhibitor. Polynucleotides and polypeptides having at least one ALK inhibitor resistance mutation are provided and find use in methods and compositions useful in the diagnosis, prognosis, and/or treatment of diseases associated with aberrant ALK activity, more particularly, those that are resistant to at least one ALK kinase inhibitors. Methods and compositions are also provided for the identification of agents that can inhibit the kinase activity and/or reduce the expression level of the ALK resistance mutants.

Abstract: The invention relates to human nucleotide sequences which occur as a result of the t(1;22)(p13;q13) chromosomal translocation event which is known to occur almost invariable in young children with acute megakaryoblastic leukemia. The translocation results in the formation of fusion genes which encode fusion proteins. The invention provides the nucleotide sequences of transcripts of the fusion genes and the amino acid sequences of the fusion proteins encoded thereby. Also provided are methods for detecting the t(1, 22) translocation, for identifying agents capable of binding to the fusion protein and for identifying agents useful for treating patients with acute megakaryoblastic leukemia.

Abstract: The present invention sets forth an integrated circuit (IC) device wherein the IC chip includes peripheral circuits, such as input/output circuits, which are arranged non-perpendicular with respect to the rectangular shape of the active area of the IC. This structure permits positioning some of the terminal bond pads closely adjacent the corners of the chip without overlap of adjacent circuits.
