Everything you need to know about WFFS

Warmblood Fragile Foal Syndrome explained (Updated: 9 February 2019)

Alles wat u moet weten over WFFSIn the past year, there has rarely been one topic as much discussed in breeding as WFFS, also known as Warmblood Fragile Foal Syndrome. It is an inherited condition in which foals are born prematurely and/or born with a disorder. The most important clinical symptoms are sometimes prematurity and further serious skin problems where pieces of skin are missing or very easily torn. Hyperextension of joints is also a common symptom. Other possible symptoms are 'floppy ears', bleeding, ... The disorder was characterized in 2013 as an autosomal recessive genetic defect. Autosomal recessive means that both parents must be carriers in order for the foal to get the condition, in other words: the healthy gene is the boss! Even if both parents are carriers (heterozygous WFFS / N), it is not certain that the foal will also get WFFS ... One out of four foals will show the problem clinically (WFFS / WFFS), two of the four foals will be heterozygote (WFFS / N) and only one foal of the four will not be a carrier of the gene (N / N). To investigate whether a horse is a carrier of the WFFS gene, a genetic test is needed. For this research, 30 to 40 dry hair roots of mane or tail are required. There are also laboratories that do tests based on oral mucosa swabs or 1ml EDTA blood. To avoid the risk of WFFS as much as possible, it is advisable to also test your broodmare. In Belgium and the Netherlands, for example, you can contact Van Haeringen Laboratorium. The test costs 39.50 euros excluding VAT. You must submit a hair sample and two signed forms, namely 'statement witness sampling' and 'submission form horse'. Meanwhile, a very large number of stallion owners and studbooks have also performed tests. To give a good overview to the breeder, JumpingStallions lists all known WFFS carriers. We also try to supplement on our website which stallions are not carriers. In addition, we also have a list of the studbooks that have already performed tests.
