Since autoimmunity frequently leads to glomerulonephritis, we studied the kidney pathology, but no glomerulonephritis or any other pathological changes in the kidney were detected in 16-day-old TRAF6[L74H] mice (Fig 6J and 6K), perhaps because the mice were too young for this phenotype to have developed. This evidence concerns the gene TRAF6 and glomerulonephritis.
