## Overview and value chain
Markers: [EC: Veterinary Genomics & Direct-to-Consumer Biotech | OECD: Biotech & Health | Regulator: FDA (USA), EMA (EU), NMPA (China)]
Veterinary genomics and companion-animal diagnostics applies human-grade
high-throughput genotyping and sequencing to pet dogs and cats, turning a
cheek-swab sample into a screen of 250+ inherited disease risks, a breed-ancestry
breakdown across 350+ breeds, and a trait panel covering coat, body size and
blood group. The technology stack rests on three pillars: SNP microarray
genotyping on custom Illumina BeadChips packing 230,000+ markers per dog,
targeted next-generation sequencing (NGS), and GWAS-grade bioinformatic
pipelines aligned to the CanFam4 reference genome. The market is concentrated
and fast-moving: the two US leaders alone have collectively tested more than
6 million animals, turnaround sits at 2–4 weeks, and a 2026 $160 million deal
saw the world's largest animal-health company absorb a global network of five
genomics laboratories across five countries.
The key directions of veterinary genomics and companion-animal diagnostics are:
1. **Genetic health-risk screening (Genetic Health Risks):** detection of
carrier status for 250+ inherited conditions — MDR1/ABCB1 drug sensitivity
in herding breeds, HCM in Maine Coons, PKD in Persians, PRA blindness —
reported as clear, carrier or at-risk.
2. **Breed ancestry identification (Breed Ancestry):** percentage decomposition
of mixed-breed animals against reference databases of 350–365+ recognised
breeds, varieties and wild canids, at 99% marker accuracy.
3. **Trait and physical-feature analysis (Traits):** coat colour and length,
shed factor, predicted adult weight, and blood group from a single genotype.
4. **Oral microbiome and predictive wellness (Predictive Wellness):** sequencing
of the feline oral microbiome linked to gingivitis risk, extending genetics
into a prognostic companion-animal health score.

providers have launched consumer sub-brands offering low-cost pet DNA testing
built on domestic NGS platforms rather than imported SNP chips.
- **University genetics research:** animal-genetics departments at institutions
such as China Agricultural University run large studies to identify
disease loci specific to endemic Asian cat and dog breeds.
- **Shenzhen DTC cluster:** a dense cluster of direct-to-consumer biotech
startups offers point-of-care PCR and LAMP-based genetic tests for veterinary
clinics, complementing chip-based screening with rapid in-clinic panels.

mandatory DNA testing into the rules of kennel and feline associations.
### Kennel Club mandatory screening, accredited labs, Helsinki biobank R&D
- **UK Kennel Club mandatory screening:** The Kennel Club requires DNA testing
for inherited disease before admitting certain breeds to registered breeding,
excluding mutation carriers from reproduction.
- **Accredited reference laboratories:** Genomia (Czech Republic) is a leading
ISO 17025-accredited central-European pet and livestock DNA centre, developing
custom PCR panels for breeders across dogs, cats, horses and birds.
- **Helsinki canine biobank:** the University of Helsinki runs one of the
world's largest canine genetic biobanks, identifying candidate genes for
epilepsy, anxiety and skeletal dysplasia in northern breeds.

## Tech stack and innovations
The veterinary DNA-testing stack is built on solid-phase hybridisation
genotyping, automated wet-lab robotics and statistical bioinformatics.
1. **Cheek-swab DNA isolation (Saliva DNA Isolation):**
- collection tubes hold lysis-preserving buffer that stabilises DNA at room
temperature for up to six months before the sample reaches the lab.
- Hamilton Microlab STAR robots dose protease and magnetic silica Dynabeads
into each well, wash under chaotropic salt and elute clean genomic DNA.
2. **SNP microarray hybridisation (Illumina Infinium BeadChip):**
- the sample is whole-genome-amplified, fragmented and hybridised onto a
custom BeadChip carrying 230,000+ 50-mer probes for 20 hours at 48 °C.
- single-base extension with fluorescent ddNTPs is read by the two-channel
Illumina iScan laser, calling homozygous-wild-type, heterozygous or
homozygous-mutant genotypes at every marker.
3. **Bioinformatic association and GWAS (Bioinformatic Association):**
- NGS reads are aligned to the CanFam4 (dog) or Felis_catus_9.0 (cat)
reference assemblies and variants are called with GATK HaplotypeCaller.
- quality-filtered variants are matched against curated disease-association
databases and combined into polygenic risk scores for multifactorial traits.

#### Stage 1: Sample receipt and barcode registration
A saliva kit mailed by the owner arrives at the robotic lab; an operator scans
the 12-digit 2D tube barcode, which syncs instantly to the owner's LIMS account,
and the tube is racked onto the automated deck.
#### Stage 2: Hamilton robotic DNA extraction
A Hamilton Microlab STAR unscrews the 96-tube rack, doses lysis buffer with
proteinase K, incubates at 56 °C for 20 minutes, then adds magnetic silica
Dynabeads; after magnetic washes the robot elutes clean genomic DNA, verified
on a Qubit fluorometer to ≥10 ng/µL at A260/280 ≥1.8.
#### Stage 3: BeadChip hybridisation
The purified DNA is whole-genome-amplified, enzymatically fragmented and
dispensed onto a custom canine BeadChip of 230,000+ silicon beads; the chip
hybridises for 20 hours at 48 °C so pet DNA binds its complementary probes, then
is washed to strip non-hybridised material.
#### Stage 4: Enzymatic extension and iScan readout
The chip moves to a staining chamber where single-base extension adds
fluorescent ddNTPs; after drying, the Illumina iScan laser excites each bead
and reads red versus green fluorescence, converting the signal into a raw IDAT
genotype file.
#### Stage 5: Bioinformatic variant calling
The IDAT files are imported by Illumina GenomeStudio for genotype clustering,
then a GATK/PLINK pipeline aligns calls to the CanFam4 reference and flags
pathogenic variants such as the ABCB1 drug-sensitivity mutation.
#### Stage 6: LIMS verification and veterinary DNA passport
Called variants are matched against clinical databases in the LIMS; any
high-risk call is manually confirmed by an on-duty geneticist before the system
generates the interactive owner-portal report and a PDF veterinary passport
with diet and screening recommendations, and emails the owner.
