SNP Analysis for Athletic Performance Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for predicting athletic performance in Thoroughbred horses are limited, as they primarily rely on pedigree and phenotypic characteristics, and mitochondrial DNA testing is insufficient due to its restriction to female ancestry and limited haplotype variation, which does not effectively capture the genetic contributions from all ancestors.
Innovation Solution
A DNA-based testing method that detects variations in nuclear-encoded genes, specifically targeting single nucleotide polymorphisms (SNPs) in genes like MSTN, COX4I2, PDK4, CKM, and COX4I1, which are associated with elite athletic performance, allowing for the prediction of sprinting and endurance capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If mitochondrial DNA testing is used to predict athletic performance, then female ancestry contribution can be assessed, but the prediction is insufficient due to limited haplotype variation and restriction to female lineage only
Solution Approach 1:
The patent segments the genetic analysis by testing multiple independent nuclear genes (MSTN, COX4I2, PDK4, CKM, COX4I1) rather than relying on a single mitochondrial DNA marker. This segmentation allows comprehensive assessment of genetic potential from all ancestral lines, resolving the limitation of mtDNA which only captures female lineage information.
Solution Approach 2:
The patent creates a universal prediction system that can assess athletic performance potential from any ancestral contribution by analyzing multiple nuclear genes. This multi-functional approach replaces the specialized mtDNA testing with a comprehensive genomic screening that works for all individuals regardless of ancestry, capturing both male and female lineage contributions.
2Measurement precision
If traditional pedigree and phenotypic characteristics are used for selection, then breeding decisions can be made, but the prediction accuracy is limited compared to direct genetic testing
Solution Approach 1:
The patent replaces the mechanical/observational system of pedigree and phenotypic assessment with a molecular biological system of direct DNA analysis. By substituting indirect observation with direct genetic testing, the system achieves superior prediction accuracy while capturing genetic potential information that would otherwise be lost or inferred imprecisely.
Solution Approach 2:
The patent enables preliminary identification of athletic performance potential through genetic testing before the animal reaches racing age. By performing DNA analysis on young animals, breeders can predict future performance capabilities early, avoiding the loss of genetic information that occurs when relying on later phenotypic expression and pedigree inference.

AI summary
A method and assay for predicting athletic performance potential of a subject, such as a thoroughbred race horse, comprising the steps of assaying a biological sample from a subject for the presence of a single nucleotide polymorphism in one or more genes associated with athletic performance. The athletic performance genes may be selected from one or more of MSTN, COX4I2, PDK4, CKM and COX4I1.
