OMIA:000083-9823 : Atresia ani in Sus scrofa (pig)

In other species: dog , domestic cat , llama , taurine cattle , goat , sheep , alpaca

Categories: Digestive / alimentary phene

Mendelian trait/disorder: unknown

Considered a defect: yes

Cross-species summary: Congenital absence of the anus, causing a buildup of faeces and consequent distension of the abdomen.

Species-specific description: A large segregation analysis of data on German pigs, by Stigler et al. (1991, 1992), showed that this disorder is definitely familial, but is also definitely not due to a single gene.
