The study was performed using several founder lines, bred onto a background strain of
mice hypomorphic for BubR1 (BubR1H / H), a key component of the mitotic checkpoint machinery.
We describe a heteroallelic,
hypomorphic genotype of mutantInR, which yields dwarf females with up to an 85 % extension of adult longevity and dwarf males with reduced late age - specific mortality.
Although direct modification of zygotic genomes may have some advantages, the strategy can result in mosaic or
hypomorphic mutation of injected animals [27]--[31], for which mutation may fail to transmit to offspring [27] and breeding will need to be further performed for obtaining homozygous (nonmosaic) animals [29].

The hypomorphic Brazilian mutant TP53 - R337H and variable tumor susceptibility: identification of a potential genetic modifier
The Pkd1 (V / V) mice show
a hypomorphic phenotype, characterized by a delayed onset and distal nephron segment involvement of cystogenesis at postnatal maturation stage.
