him-6 encodes a RecQ-like ATP-dependent DNA helicase orthologous to human BLM (OMIM:604610, mutated in Bloom syndrome); HIM-6 is required for normal levels of recombination during meiosis and as such, loss of HIM-6 function results in an increased frequency of genotypically XO males and inviable aneuoploid embryos as a result of higher levels of chromosome nondisjunction; HIM-6 interacts both genetically and in vitro with TOP-3, DNA topoisomerase IIIalpha, with which it functions to regulate genomic stability during germ-line mitosis; HIM-6 is expressed primarily in the germ line.
