We are currently working on tests for Naked Foal Syndrome which occurs in Akhal-Teke Horses.
NFS is a lethal disorder and is just as strange as it sounds.
Pic is from the G3Journal : NFS phenotype. (A) An NFS affected colt (case 1) in front of its nonaffected mother. The affected colt has almost no hair. Both horses are of cremello coat color (SLC45A2:c.457G>A), which leads to a very strong dilution of the pigmentation but is unrelated to the NFS phenotype. (B) NFS affected filly (case 2).
