OMIA:000629-9986 : Megacolon in Oryctolagus cuniculus (rabbit)
Categories: Digestive / alimentary phene
Links to MONDO diseases: No links.
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.
Have human generated variants been created, e.g. through genetic engineering and gene editing
