wow, that's all we need. Another potential defect to watch out for.
Barrel Racer- any bloodlines these calves had in common?

Red,
We've only gotten the few that I spoke of and a lot of times, bottom sides of animals are blank.  We can't find anything in common with the small number we have, which is why I say it might not even be a genetic disorder, we just don't know.  If it is something genetic, it's going to take the same breeder cooperation looking out for these calves, documenting bloodlines and getting samples (cow, bull, calf) as it took to find TH, PHA, and now epilepsy.  With the tools that are available now, once a lab has the samples they need it shouldn't take long, provided it's a simple recessive or dominant trait, those traits involving more than one gene are extremely difficult to pinpoint.
