OMIA:000978-9031 : Talpid-2 in Gallus gallus (chicken)

Categories: Limbs / fins / digit / tail phene

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal recessive

Considered a defect: yes

Key variant known: no

Clinical features: "Homozygotes (-/-) display extreme preaxial polydactly, exposed viscera, cleft palate, parrot-like beak, and dwarfing with greatly reduced leg and wing proximal bones in addition to the duplication of the distal digit bones" (Robb et al., 2011)
