OMIA:001732-93934 : Chondrodystrophy-2 in Coturnix japonica (Japanese quail) |
Categories: Skeleton phene (incl. short stature & teeth)
Single-gene trait/disorder: yes
Mode of inheritance: Autosomal recessive
Disease-related: yes
Key variant known: no
Species-specific symbol: ch-2
History: Hermes et al. (1990) were the first to report this disorder, which is different to the previous chondrodystrophy reported by Collins et al. (1968) in quail (see OMIA000189-93934)
Inheritance: Hermes et al. (1990) reported autosomal recessive inheritance.
Clinical features: As summarised by Hermes et al. (1990): "an overall shortening and bending of the long bones of the wings and legs, slight dwarfing of the trunk, bulging of the eyes, flattening of the head, and a parrot beak. The shortened long bones vary in regard to the amount of bending from nearly straight to bends of up to 90° in the midshaft region. In severe cases, the bend is evident as a protuberance of the skin. Affected embryos usually survive the 18-day incubation period. Several have hatched, but most survived no longer than 4 days after hatching. Only one female has survived long enough to lay eggs."
