limbs/digits/tail
abnormal digit morphology ( J:149478 )
• at P1, digits appear posteriorized comparing relative digit length and phalanx morphology with that of controls Shhtm1Amc/Shhtm2Amc Tg(Prrx1-cre)1Cjt mice
• however, mice have the same number of digits as in Shhtm1Amc/Shhtm2Amc Tg(Prrx1-cre)1Cjt mice

limbs/digits/tail
abnormal limb morphology ( J:149478 )
• less well-formed ectopic cartilaginous elements are observed in the anterior limb unlike in wild-type mice
polyphalangy ( J:149478 )
• the most anterior digit contains three phalanges instead of the normal two
polydactyly ( J:149478 )
• mice have 6 to 7 digits unlike in wild-type mice
• in some cases, the ectopic digit is more centrally located and consists of three phalangeal elements without an additional metacarpal element
