Ferret - Waardenburg Syndrome

Ferrets with a white stripe on their face or a fully white head, primarily blazes, badgers, and pandas, almost certainly carry a congenital defect known as Waardenburg syndrome. This causes, among other things, a cranial deformation in the womb which broadens the skull, causing the white face markings but also partial or total deafness. It is estimated as many as 75% of ferrets with visible Waardenburg signs are deaf. Beyond that, the cranial deformation also causes a higher instance of stillborn ferret kits, and occasionally cleft palates. Because of this, many breeders will not breed Waardenburg-patterned ferrets.

Något som är typiskt för illrar med WS är att öronen ofta sitter högre upp än normalt, och "tätare".

Det var ett litet tillägg! :)
