Research context: Our feline case study (DOI: 10.13140/RG.2.2.19040.19200) identified an interesting correlation between iris coloration and genetic disease status that could potentially serve as a clinical screening tool.
Observed pattern:
- Blue eyes: Associated with disease/carrier status
- Green eyes: Associated with normal genetic status
- Mixed coloration: Variable expression (possibly X-inactivation related)
Current limitations:
❌ Single family observation (n=7 individuals)
❌ No statistical validation possible with current sample size
❌ No molecular genetic confirmation yet
❌ Unknown mechanism linking eye pigmentation to disease genes
Questions for the research community:
1. What sample sizes would be needed for statistical validation?
2. Which study designs are most appropriate for genetic marker validation?
3. Are there established protocols for phenotype-genotype correlation studies in veterinary medicine?
4. What regulatory considerations apply to new diagnostic markers?
5. Any similar examples of unexpected phenotypic markers in veterinary genetics?
Seeking collaboration opportunities with:
- Veterinary geneticists experienced in marker validation
- Statisticians familiar with genetic association studies
- Ophthalmologists interested in genetic correlations
- Regulatory experts in veterinary diagnostics
Would greatly appreciate guidance from researchers who have successfully validated genetic markers in veterinary medicine.
