The Axiom Canine HD Array was designed as part of the Expert Array Design program. The array was developed by selecting more than 2,000 samples using sets A and B of the Axiom Canine Genotyping Array. The samples covered more than 50 breeds and were carefully selected with appropriate pedigree to maximize polymorphic content. The array offers more than 710,000 markers for validation and discovery of variants associated with specific phenotypes. The array content was aligned with the CanFam3 reference genome..

Features include:
• More than 710,000 markers with inherited content from arrays on the market including new variants
• Functional variants of biological relevance
• Intergenic variants based on recently available long non-coding RNA (lncRNA) data
• miRNA variants
• Breed-specific markers
• More than 150 disease and trait-specific markers
