The affected animals present with broken and delaminated feet, which struggle to hold shoes or maintain soundness. It is a serious issue and steps are now being taken to screen breeding animals so that the disease does not become more widespread.

This mutated gene can be passed onto the offspring regardless of the gender of the parent or offspring (autosomal). The fact it is a recessive gene means that symptoms will only present, if, the offspring inherits the mutated gene from both parents. A pony may be a carrier, with only one copy of the mutated gene.
