OMIA:000629-9986 : Megacolon in Oryctolagus cuniculus (rabbit)

In other species: domestic cat , horse , pig , taurine cattle

Categories: Digestive / alimentary phene

Possibly relevant human trait(s) and/or gene(s)s (MIM numbers): 600155 (trait) , 277580 (trait) , 600501 (trait) , 131244 (gene)

Mendelian trait/disorder: unknown

Considered a defect: yes

Cross-species summary: Also known as Hirschsprung disease. A disorder in which the large intestine (caecum, colon and sometimes the rectum) undergoes a large dilation and fills with faecal mass. Associated with incomplete migration of nerve cells to the intestine during embryonic development, resulting in lack of peristalsis and hence a build-up of faecal material.

Molecular basis: Fontanesi et al. (2015) reported enticing associations between megacolon and levels of KIT gene expression but were not able to find a causal mutation in the KIT gene.

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