Autism Genetic Variant Detection via Genome-Wide Association
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for diagnosing and treating autism spectrum disorders have limited success in identifying genetic determinants due to the complexity of interactions between multiple genetic and environmental factors, with existing linkage analysis approaches being poor at identifying common genetic variants with modest effects.
Innovation Solution
The development of methods and compositions for detecting copy number variations (CNVs) and single nucleotide polymorphisms (SNPs) associated with an increased risk of autism, including specific chromosomal regions and SNPs, to identify genetic predispositions and potential therapeutic agents that alter neuronal signaling and morphology.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If linkage analysis approaches are used to identify genetic determinants of autism, then the method can be applied to study genetic inheritance patterns, but the approach is poor at identifying common genetic variants with modest effects
Solution Approach 1:
The patent transitions from linkage analysis to genome-wide association study (GWAS), changing the fundamental parameter of the genetic analysis approach. GWAS allows for the identification of common genetic variants with modest effects by scanning the entire genome for associations with autism, overcoming the limitations of linkage analysis which is better suited for rare variants with large effects.
2Measurement precision
If genome-wide association study is conducted to identify common genetic variants, then the ability to detect modest genetic effects is improved, but the complexity of analyzing interactions between multiple genetic and environmental factors increases
Solution Approach 1:
The patent segments the complex genetic architecture of autism into identifiable common variants through GWAS. By focusing on common genetic variants with modest effects rather than attempting to analyze all genetic and environmental factors simultaneously, the approach makes the complex problem tractable while still providing valuable diagnostic and therapeutic insights.
3Loss of information
If multiple genetic and environmental factors are considered in autism etiology, then the comprehensive understanding of the disorder is improved, but the difficulty of identifying specific genetic determinants increases
Solution Approach 1:
The patent extracts specific common genetic variants associated with autism through GWAS, separating them from the complex background of multiple genetic and environmental factors. This extraction approach allows for the identification of specific genetic determinants that can be used for diagnosis and treatment while acknowledging the broader complexity of autism etiology.
