FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The Bloom syndrome gene product is related to the RecQ subset of DExH box-containing DNA helicases and has both DNA-stimulated ATPase and ATP-dependent DNA helicase activities. Mutations causing Bloom syndrome delete or alter helicase motifs and may disable the 3'-5' helicase activity. The normal protein may act to suppress inappropriate recombination.

PHENOTYPE: 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.
