Representative testes, seminal vesicles, and uteri from wild-type, Cdkn1ctm1Kat/Cdkn1c+, and Cdkn1ctm1.1(Cdkn1b*)Kei/Cdkn1c+ mice at 7 weeks of age

mortality/aging
N
• unlike null mice, all knock in mice survive

cellular
• all mice carry a maternally inherited mutant allele

growth/size/body
N
• unlike null mice, knock in mice grow at a rate similar to controls
• thinning of the abdominal wall or omphalocele are seen
• thinning of the abdominal wall or omphalocele are seen

renal/urinary system

endocrine/exocrine glands
• enlargement is less pronounced compared to null mice

reproductive system
• present in 2 of 9 mice
• incidence is decreased compared to null mice
• present in 3 of 15 mice
• incidence is decreased compared to null mice

embryo

digestive/alimentary system
N
• cleft palate and shortening of the intestines seen in null mice are largely corrected in knock in mice

vision/eye
N
• unlike null mice, knock in mice do not develop cataracts and do not display increased cell proliferation in the lens

skeleton
N
• rib and vertebral deformities, delayed bone ossification, decreased length of the long bones, and aberrant cell proliferation seen in null mice are largely corrected in knock in mice
