Pseudogene Mapping for Retrotransposition Activity Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods fail to effectively utilize pseudogenes as proxies for retrotransposition activity detection, which is associated with cancer development and progression, limiting diagnostic and screening capabilities in oncology.
Innovation Solution
A method involving determining sequence reads of a target chromosome region, aligning them to a reference genome, subtracting aligned pairs, and mapping unaligned reads to identify integration sites, allowing for the detection of retrotransposition activity through pseudogene analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pseudogenes are used as proxies for retrotransposition activity detection, then diagnostic capability for cancer is improved, but the complexity of sequence analysis and integration site identification increases
Solution Approach 1:
The method segments the complex sequence analysis process into distinct steps: aligning sequence reads to reference genome, identifying pseudogene loci, detecting integration sites, and analyzing retrotransposition activity. This segmentation allows each step to be processed independently, managing complexity while maintaining diagnostic reliability.
Solution Approach 2:
The patent performs preliminary alignment of sequence reads to the reference genome before analyzing pseudogene-specific features. By pre-aligning reads and identifying known pseudogene locations in advance, the method simplifies subsequent detection of retrotransposition integration sites and reduces the complexity of real-time analysis.
2Measurement precision
If multiple alignment and mapping steps are performed to identify integration sites, then measurement precision of retrotransposition activity is improved, but processing time increases
Solution Approach 1:
The method performs alignment and mapping steps selectively rather than exhaustively. It focuses computational resources on regions containing pseudogenes and potential integration sites, performing detailed analysis only where retrotransposition activity is suspected, thereby balancing precision with processing efficiency.
Solution Approach 2:
The patent applies different analysis depths to different genomic regions. High-precision alignment and mapping are performed specifically at pseudogene loci and potential integration sites, while other regions receive minimal or no analysis. This localized approach maintains measurement precision for critical regions while reducing overall processing time.
