Homozygous null mutants are developmentally delayed, with increased apopotosis in the epiblast and severe anemia, dying at embyronic day 13.5; but homozygotes for a cre mediated recombinant allele are viable Bloom syndrome-like mice prone to a wide variety of cancers and showing increased rates of LOH.
