Résumé
There are about 40% of patients with type 1 and type 2 diabetes will develop diabetic nephropathy (DN), resulting in chronic kidney disease and potential organ failure. During the progression and development of DN, chronic elevated blood glucose (hyperglycaemia) together with glomerular hypertension leads to renal inflammation, progressive glomerulosclerosis and tubulointerstitial fibrosis resulting in organ failure. Genetic variants at a biomarker level could allow the detection of those individuals at high risk for diabetic nephropathy which could thus help in the treatment, diagnosis and early prevention of the disease. Current genome-wide relationship scans have recognized a number of chromosomal regions that possible include diabetic nephropathy susceptibility genes, and association analyses have evaluated positional applicant genes under these relation peaks. The possibility of increasing diabetic nephropathy is recovered several times by inheriting risk alleles at susceptibility loci of dissimilar genes like GST (glutathione-Stransferase), TCF (Transcription factor), ELMO1 (Engulfment and Cell Motility 1), IL-10 (Interleukin-10) and TRPC1 (transient receptor potential channel 1). The identification of these genetic variants at a biomarker level could thus, allow the detection of those individuals at high risk for diabetic nephropathy which could thus help in the treatment, diagnosis and early prevention of the disease.
