Abstract: Disclosed are methods and kits for detecting the presence of a cancer in a subject and assessing the efficacy of treatments for the same. The disclosed method use reverse transcription polymerase chain reaction (RT-PCR) techniques to detect the presence of point mutations, truncations, or fusions of anaplastic lymphoma kinase.

Abstract: Disclosed are methods, assays, and compositions for detecting the presence of a kinase inhibitor resistance. The disclosed method and primer panels work with any method for detecting nucleic acid variation in a sample including, but not limited to next generation sequencing.

Abstract: Disclosed are methods and compositions for detecting variation in nucleic acids. The disclosed method compares the sequence of a nucleic acid of interest with the sequence of a reference nucleic acid to sensitively identify variations between the sequence of a nucleic acid of interest and the sequence of a reference nucleic acid. The disclosed method generally involves excision and replacement of selected nucleotides in nucleic acid strands hybridized to other strands. In the method, if the excised nucleotide was mismatched with the nucleotide in the other, hybridized strand, then the replacement nucleotide will not be mismatched. If the excised nucleotide was not mismatched with the nucleotide in the other, hybridized strand, then the excised nucleotide is not replaced. This difference allows detection of variation in the nucleic acid of interest.
