Abstract |
We describe here, to our knowledge for the first time, associations between polymorphisms at the genomic DNA level in the immunoglobulin gene region and renal diseases which lead to chronic renal failure. Recent studies have shown that protein polymorphisms, present in immunoglobulin ( Ig) heavy chains ( Gm allotypes) are associated with certain forms of renal disease and with end stage renal failure per se. To investigate this association at the DNA level we have used probes which recognize Ig heavy chain genes and this report describes results obtained with one of these, the S mu switch region probe. With the restriction endonuclease Sst 1 (or the isoschizomer; Sac I) a number of restriction fragment length polymorphisms (RFLP) can be obtained which are recognized by this probe and there is a highly significant association between certain of these and renal disease. This is the first report of Ig switch region polymorphisms being associated with disease, yet our results suggest that S mu RFLP are more closely linked to renal disease than Ig protein polymorphisms.
