Naked foal syndrome (NFS) is a fatal inherited disorder that has been found in pure and part-bred Akhal Teke horses.

Foals with NFS are born without hair, and may have other physical abnormalities too.

All NFS-affected horses recorded so far have died before three years of age.

The cause of death is not known.
