OMIA:000044-9809 : Anencephaly/Exencephaly in Rhinoceros unicornis (greater Indian rhinoceros)

In other species: dog , brown bear , domestic cat , taurine cattle , sheep , Indo-pacific bottlenose dolphin

Categories: Nervous system phene

Links to possible relevant human trait(s) and/or gene(s) in OMIM: 182940 (trait) , 206500 (trait) , 301410 (trait) , 619452 (trait)

Mendelian trait/disorder: unknown

Considered a defect: yes

Cross-species summary: Congenital absence of the cranial vault, with the cerebral hemispheres completely missing or reduced to small masses. This phene was originally called anencephaly, but a recent review suggested that the term anencephaly/exencephaly is more appropriate.

Species-specific description: A single rhinoceros fetus was described with partial anencephaly (aplasia of the cerebrum) and hypoplasia of the cerebellum (Schaftenaar et al., 2011).
