From genome to phenotype — the complete equine genomics analysis pipeline

Research Methodology

From raw sequencing data to actionable insights — a complete equine genomics analysis pipeline

1

WGS Sequencing

Illumina NovaSeq platform, 150bp paired-end sequencing, average 30X coverage depth

2

Variant Calling

GATK 4.x best practices pipeline, SNP/Indel/SV detection across all variant types with stringent QC

3

Functional Annotation

VEP transcript annotation + SIFT/PolyPhen-2 dual-algorithm missense prediction + structural variant annotation

4

Causal Inference

Multi-omics evidence integration from GWAS + WGS, Tier A/B/C causal stratification, regulatory network construction

5

Phenotype Prediction

NCDS v3.4 model-driven precise prediction from genotype to athletic aptitude and hereditary disease risk

Core Algorithm

NCDS v3.4 — Neuro-Centric Differentiable System

🧠 Tri-Modular Architecture

NCDS v3.4 integrates three biological dimensions: Neural Regulation (34 genes), Skeletal Development (38 genes), and Growth & Development (30 genes) — a systematic 102-gene functional architecture with 90% core gene validation rate.

  • Neural module: signal transduction, synaptic plasticity, neuromuscular junction
  • Skeletal module: muscle fiber type, energy metabolism, muscle contraction
  • Developmental module: growth factors, hormonal regulation, nutrient metabolism

📊 Athletic Scoring Engine

7 athletic scoring engines covering all performance assessment scenarios, calibrated against 400+ breed baseline data for precise prediction across Sprint, Endurance, Dressage, Jumping, and Racing dimensions.

  • Sprint Index — explosive power assessment
  • Endurance Index — aerobic capacity evaluation
  • Dressage Index — coordination and collection
  • Jumping Index — power-to-weight ratio
  • Racing Index — composite performance metric

Data Pipeline Architecture

JumpChain™ whole-genome variant database construction workflow
