Analysis of gene function in vivo is currently mostly performed by transgenic insertion, inactivation of the respective gene by homologous recombination in embryonic stem cells and gene trapping. We have complemented this approach by isolation of mouse lines with phenotypic immunological alterations which were produced within the Munich ENU-mouse mutagenesis project.

In this phenotypic approach C3HeB/FeJ are randomly mutagenized using the potent mutagen ethyl-nitrosourea (ENU). ENU is most potent during spermatogenesis and therefore mutagenesis is performed on male mice which are subsequently crossed to female WT mice. Progeny thereof are analyzed for inherited immunological alterations using a panel of immunological parameters.

Out of more than 50 mutant lines isolated with this approach we have analysed two in more detail and mapped the corresponding mutation. Data from this analysis will be presented. <> in Microsoft Word 6.0 format with margins of 2.5cm together with all of the details requested in this form.
