• surprisingly, none of >100 heterozygotes studied show any macroscopic signs of retinoblastoma relative to wild-type mice (J:2516)
• survival of 65 diet restricted heterozygous males is almost identical to that of 67 heterozygous males fed ad libitum (J:79648)
• surprisingly, 40-50% reductions in dietary intake, relative to an ad libitum group, initiated on either P28 or P42 have minimal to no effect on either the frequency or growth of pituitary tumors either during the latency period (P224) or at the time of natural death (J:79648)
• at >8 months of age, 90% of heterozygotes display signs of pituitary tumors as a "wasting" syndrome; both sexes are susceptible to tumor development
• in young heterozygotes, foci of anaplasia or micro-tumors arise from the intermediate lobe and outgrow toward the neuronal lobe of pituitary glands
• multiple foci are frequently observed in the tiny intermediate lobe of the pituitary gland; on average, 2.2. tumors devepo per intermediate lobe
• in heterozygotes, tumor tissues invariably lose expression of full-length protein due to loss of the remaining wild-type allele
• in heterozygotes, tumor incidence increases with age, with a 21% predisposition at the age of <6 months, >50% at 6-8 months, and 100% at 10 months; the earliest tumor was detected at 2 months
• at an advanced stage, pituitary tumors often infiltrate other tissues e.g. hypothalamus, optic nerved, pons, cerebellum, third ventricle, meninges and subarachnoid space
• distal metastasis to the cervical lymph nodes and spinal cord is also detected
• heterozygotes develop brain tumors at the ages of 4, 7, 8 and 12 months; such tumors are found to arise from cells in which the wild-type allele is absent

growth/size/body
• heterozygotes exhibit a 10% increase in body mass relative to wild-type; although this change is reproducible, no excess accumulation of fat is observed
• heterozygotes bearing large pituitary tumors (~7 mm in diameter) exhibit a severe wasting syndrome
• ~3% of tumor-bearing heterozygotes are obese, probably as a result of elevated ACTH levels

immune system
• two mutant mice died at early stages (2.7 and 5.4 months) as a result of increased susceptibility to infection, however showed no evidence of tumorigenic lesions in these mice

mortality/aging
• females displaying vaginal atresia accumulate fluid in the uterus and die between 4 and 6 months of age
• similar to Rb1tm1Tyj heterozygotes, any surviving mutant mice eventually die of pituitary tumors after 12 months
• at 1 week of age, mutant pups are obtained at a significantly lower frequency (19%) than expected (25%)
• most mutants die within the first 3 weeks of age, with only about 25% surviving beyond 3 weeks

endocrine/exocrine glands
• similar to Rb1tm1Tyj heterozygotes, all surviving mutant mice develop large pituitary adenocarcinomas of the intermediate lobe

growth/size/body
• mutant pups become runted several days after birth
• beginning at ~1 week, mutant pups appear severely growth retarded, averaging 50% of the weight of control littermates
• mutants surviving beyond 3 weeks of age gain weight slowly, averaging 70-90% of normal weight at 3 months
• although mutant pups are of approximately uniform size at birth, a number of pups display severe growth retardation, with weight differences persisting for several weeks
• females displaying vaginal atresia have a distended abdomen as a result of fluid accumulation in the uterus

neoplasm
• similar to Rb1tm1Tyj heterozygotes, all surviving mutant mice develop large pituitary adenocarcinomas of the intermediate lobe

reproductive system
• females displaying vaginal atresia have a distended perineum as a result of fluid accumulation in the uterus
• ~75% of mutant females display vaginal atresia whereas the majority of mutant males surviving beyond 3 weeks of age are fertile and appear normal up to 12 months
• in affected females, the vaginal opening is absent; however, the rest of the reproductive tract appears unaffected

vision/eye
• at 4-6 months, all mutant mice display retinal dysplasia; both eyes are affected in 11 out of 12 mutants
• typically, each eye contains 5-7 individual lesions composed of small white bodies (usually in clusters), indicating retinal pathology
• as early as 4 days after birth, mutant newborns exhibit mild, yet significant, disruptions of the retinal photoreceptor layer

nervous system
• similar to Rb1tm1Tyj heterozygotes, all surviving mutant mice develop large pituitary adenocarcinomas of the intermediate lobe
• as early as 4 days after birth, mutant newborns exhibit mild, yet significant, disruptions of the retinal photoreceptor layer

digestive/alimentary system
• females displaying vaginal atresia have a distended perineum as a result of fluid accumulation in the uterus
