In other species: white-tufted-ear marmoset , dog , domestic cat , Asiatic elephant , pig , red deer , Northern giraffe , taurine cattle , indicine cattle (zebu) , goat , sheep , rabbit , callipterus cichlid , Angolan giraffe
Categories: Skeleton phene (incl. short stature & teeth) , Growth / size / body region phene
Mendelian trait/disorder: unknown
Disease-related: yes
Molecular basis: Mendoza et al. (2020) "report the first equine case of a complex unbalanced X-autosome rearrangement in a healthy but short in stature Thoroughbred mare. Studies of about 200 cells by chromosome banding and FISH revealed an abnormal 2n = 63,X,der(X;16) karyotype with a large dicentric derivative chromosome (der). The der was comprised of normal Xp material, a palindromic duplication of Xq12q21, and a translocation of chromosome 16 to the inverted Xq12q21 segment by the centromere, whereas the distal Xq22q29 was deleted from the der."
