In other species: Japanese quail

Categories: Skeleton phene (incl. short stature & teeth)

Links to MONDO diseases: No links.

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal recessive

Considered a defect: yes

Key variant known: no

Species-specific symbol: cn

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

Clinical features: "Homozygotes (-/-) are edemic and dwarfed with crooked, fragile necks, thin amuscular legs, and no voluntary muscle contractions" (Robb et al., 2011)
