Gene Test, Research Unravel Severe Skeletal Atavism Limb Deformity in Shetland Ponies

Limbs of a 16-week old Shetland pony with Skeletal Atavism, often described as "bow legs". (Left) caudal view when standing; (center) caudal view when walking and (right) view from the front when standing square.  Complete, or "fused", fibulas and ulnas cause instability in the tarsocrural and antebrachiocarpal joints respectively; the angular limb deformity becomes more severe at the walk. Photo: Ove Wattle
Skeletal Atavism is a genetic defect that can cause skeletal deformities in Shetland ponies. The deformity has now been genetically identified by researchers at Uppsala University and the Swedish University of Agricultural Sciences (SLU), in cooperation with colleagues in the USA at Texas A&M University, the University of Kentucky's Gluck Center, and the University of Washington, as well as at the University of Qatar in the Middle East. The discovery means that healthy carriers now can be identified for better breeding decisions with the use of a gene test.
