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.
