limbs/digits/tail
N
• no difference in caspase 3 staining of limbs is detected, indicating that increased apoptosis is not causative (J:71694)
• in both front and rear feet
• both fore- and hindpaws have markedly shortened digits with absence of the second phalanges and an abnormal aspect of the digits
• in both front and rear feet (J:47974)
• sometimes found in hindpaws but with incomplete penetrance (J:71694)
• in both front and rear feet
• reduction in size and number of tarsal bones in all four feet
• reduction in size and number of carpal bones in all four feet, however long bones of the limb appear normal
• reduction in number of metacarpal bones in all four feet
• reduction in size of metacarpal bones in all four feet
• metatarsal bones are ill-shaped
• reduction in number of metatarsal bones in all four feet
• reduction in size of metatarsal bones in all four feet

reproductive system
• absent preputial glands in both sexes (J:47974)
• seminal vesicles exhibit decreased folding (J:47974)
• however, testes, epididymis and spermatogenesis appeared normal (J:47974)
(J:47974)

endocrine/exocrine glands
• absent preputial glands in both sexes (J:47974)
• seminal vesicles exhibit decreased folding (J:47974)
• however, testes, epididymis and spermatogenesis appeared normal (J:47974)

skeleton
• reduction in size and number of tarsal bones in all four feet
• reduction in size and number of carpal bones in all four feet, however long bones of the limb appear normal
• reduction in number of metacarpal bones in all four feet
• reduction in size of metacarpal bones in all four feet
• metatarsal bones are ill-shaped
• reduction in number of metatarsal bones in all four feet
• reduction in size of metatarsal bones in all four feet
• ossification of metacarpals, metatarsals and some phalanges was not visible at P0.5 and ossification centers were unpatterned at P6
• developing forelimbs at embryonic day 12.5 have much less collagen type II expression than in wildtype and at 8 days after birth ossification centers are absent from the paws

renal/urinary system
• absent preputial glands in both sexes (J:47974)

integument
• absent preputial glands in both sexes (J:47974)
