Mapping and Phenotype information for this QTL, its variants and associated markers

J:45708

In a (MRL-Tnfrsf6^lpr x C57BL/6-Tnfrsf6^lpr)F1 cross involving 274 F2 progeny a quantitative trait locus, Lmb4, identifying lymphadenopathy and/or splenomegaly was significantly associated with a region of mouse Chromosome 10 flanked by markers D10Mit20 and D10Mit11. The highest LOD scores were associated with D10Mit11.
