This website contains results of DNA testing for the
CEA/CH (Collie Eye Anomaly / Choroidal Hypoplasia),
CL (NCL - Neuronal Ceroid Lipofuscinosis),
and TNS (Trapped Neutrophil Syndrome) genes in Border Collies.

The Border Collie Health CEA/CH, CL, and TNS databases are owned and maintained independently from
any club, registry or other political organization. All Border Collie owners and breeders are encouraged
to submit their genetic testing results in order to help eliminate heritable diseases.

These results are individually submitted. If you would like your results included on any
of the databases, please click on the appropiate link(s) and fill out the submission form(s).
