OAAM-Occipitoatlantoaxial Malformation

OAAM is a developmental defect which involves malformation of the first two cervical vertebrae. Affected animals exhibit abnormal posture and varying degrees of ataxia. The condition was first described in the 1970s. In 2017 researchers at the University of California Davis described a deleted segment of DNA in an affected animal that had inherited one copy of that deletion from each parent. This finding is the basis of our test for OAAM which is inherited as a recessive trait.
