limbs/digits/tail

abnormal autopod morphology ( J:124813 )

• homozygotes show striking abnormalities of the autopod (manus and pes)

brachypodia ( J:31930 )

• homozygotes exhibit brachypodism, as shown by X-ray photographs of the hindlimbs

abnormal phalanx morphology ( J:124813 )

• either the middle or proximal phalanx is usually lost

brachyphalangia ( J:124813 )

• mutant phalanges excluding the terminal one appear underdeveloped
