Detection of gene fusions by intragenic differential expression (IDE) using average cycle thresholds
Patent number: 9914973Abstract: Described herein are methods and kits for detecting the presence or absence of gene dysregulations such as those arising from gene fusions and/or chromosomal abnormalities, e.g. translocations, insertions, inversions and deletions. The methods, compositions and kits are useful for detecting mutations that cause the differential expression of a 5? portion of a target gene relative to the 3? region of the target gene. The average expression of the 5? portion of the target gene is compared with the average expression of the 3? portion of the target gene to determine an intragenic differential expression (IDE). The IDE can then be used to determine if a dysregulation or a particular disease (or susceptibility to a disease) is present or absent in a subject or sample.Type: GrantFiled: March 24, 2015Date of Patent: March 13, 2018Assignee: Quest Diagnostics Investments IncorporatedInventor: Shih-Min Cheng -

Patent number: 9856527Abstract: Disclosed are compositions and methods for making differentiable amplicon species at unequal ratios using a single amplification system in a single vessel. The number of differentiable amplicons and their ratios to one another are chosen to span the required linear dynamic range for the amplification reaction and to accommodate limitations of the measuring system used to determine the amount of amplicon generated. Unequal amounts of distinguishable amplicon species are generated by providing unequal amounts of one or more amplification reaction components (e.g., distinguishable amplification oligomers, natural and unnatural NTP in an NTP mix, or the like). The amount of target nucleic acid present in a test sample is determined using the linear detection range generated from detection of one or more amplicon species having an amount within the dynamic range of detection.Type: GrantFiled: May 23, 2016Date of Patent: January 2, 2018Assignee: GEN-PROBE INCORPORATEDInventors: Daniel L.
