Etiology:  Hereditary mandibular prognathism is due to an autosomal recessive trait with incomplete penetrance. Diet may also be a factor in the initiation of the condition [1].


Incidence:  The incidence of malocclusion is moderate.

Clinical Signs: Signs of improper occlusion of incisors are apparent on physical exam by 3 weeks of age.  The rabbit may present with poor body condition and/or poor growth rate.

Diagnosis:  Diagnosis is made by performing an oral examination.
