OMIA:000147-9793 : Brachygnathia in Equus asinus (ass (donkey))

In other species: dog , horse , pig , llama , giraffe , taurine cattle , sheep , alpaca

Categories: Craniofacial phene

Links to MONDO diseases: No links.

Mendelian trait/disorder: unknown

Considered a defect: yes

Cross-species summary: Congenital abnormal shortness of the mandible (lower jaw), resulting in protrusion of the maxilla (upper jaw).

Markers: Using a comparative candidate gene strategy, based on evidence from humans, Rodrigues et al. (2013) could not identify any marker in the MATN1 gene (encoding Matrilin-1) to be associated with this disorder.

Genetic engineering: Unknown
Have human generated variants been created, e.g. through genetic engineering and gene editing

Breed: Zamorano-Leonés-Spain, Spain (Ass) (VBO_0001829).
