- Del refers to the ECA13 16 kb deletion and Ref signifies detection of the reference allele.
- Genotyping for the deletion was completed through an allele specific PCR assay in the phenotyped cohort (n = 94) and in an additional sample set of horses that were not phenotyped for disease, which estimated the allele frequency to be 32.34%.
