The - 429 T/C and - 374 T/A Gene Polymorphisms of the Receptor of Advanced Glycation End Products Gene are not Risk Factors for Diabetic Retinopathy in Caucasians with Type 2 Diabetes

Zusammenfassung

Hintergrund: Das Ziel dieser Studie war die Untersuchung der Beziehung zwischen den - 429 T/C und - 374 T/A Genpolymorphismen der Rezeptoren vom „advanced glycation end products” (RAGE)-Gen und der Entwicklung der diabetischen Retinopathie bei Kaukasiern mit Diabetes Typ II. Material und Methoden: 116 Patienten mit Diabetes Typ II und diabetischer Retinopathie wurden verglichen mit 70 Diabetikern ohne diabetische Retinopathie. Weiterhin wurden 76 Patienten mit proliferativer diabetischer Retinopathie (eine Untergruppe der diabetischen Retinopathie) verglichen mit 70 Diabetikern ohne diabetische Retinopathie. Ergebnisse: Die - 429 T/C und die - 374 T/A RAGE-Genverteilung bei Patienten mit diabetischer Retinopathie (- 429 T/C: CC 0,9 %, TC 29,9 %, TT 73 %, - 374 % T/A: AA 9,5 %, TA 47,4 %, TT 43,11) war nicht signifikant verschieden von der bei Diabetikern ohne diabetische Retinopathie (- 4,29 T/C: CC: 01, TC 25,71, TT 74,31; - 374 T/A: AA 15,71, TA 42,91, TT 41,41). Weiterhin war die - 429 T/C und die - 374 T/A RAGE-Gen-Verteilung bei Patienten mit proliferativer diabetischer Retinopathie statistisch nicht signifikant verschieden von der bei Diabetikern ohne Retinopathie. Schlussfolgerungen: Unsere Studie konnte keine Assoziation zwischen den - 429 T/C- bzw. - 374 T/A-Genpolymorphismus des RAGE-Gens und diabetischer Retinopathie bei Kaukasiern mit Diabetes Typ II feststellen. Ebenso konnte keine Assoziation zwischen - 429 T/C- bzw. - 374 T/A-Genpolymorphismus des RAGE-Gens und der proliferativen diabetischen Retinopathie bei Kaukasiern mit Diabetes Typ II aufgezeigt werden.

Abstract

Objective: The aim of this study was to look for a relationship between the - 429 T/C and the - 374 T/A gene polymorphisms of the receptor of advanced glycation end products (RAGE) gene and the development of diabetic retinopathy in Caucasians with type 2 diabetes. Materials and methods: One hundred and sixteen subjects with type 2 diabetes and diabetic retinopathy were compared to 70 diabetic subjects without diabetic retinopathy. Additionally, 76 subjects with proliferative diabetic retinopathy (a subgroup of diabetic retinopathy) were compared to 70 diabetic subjects without diabetic retinopathy. Results: The - 429 T/C and the - 374 T/A RAGE gene distributions in patients with diabetic retinopathy (- 429 T/C: CC 0.9 %, TC 25.9 %, TT 73.2 %; - 374 T/A: AA 9.5 %, TA 47.4 %, TT 43.1 %) were not significantly different from those of diabetic subjects without retinopathy (- 429 T/C: CC 0 %, TC 25.7 %, TT 74.3 %; - 374 T/A: AA 15.7 %, TA 42.9 %, TT 41.4 %). Moreover, the - 429 T/C and the - 374 T/A RAGE gene distributions in patients with proliferative diabetic retinopathy were not statistically significantly different from those in diabetic subjects without retinopathy. Conclusion: Our study failed to demonstrate an association between either - 429 T/C or - 374 T/A gene polymorphism of the RAGE gene and diabetic retinopathy in Caucasians with type 2 diabetes. Additionally, we failed to demonstrate an association between either - 429 T/C or - 374 T/A gene polymorphism of the RAGE gene and proliferative diabetic retinopathy in Caucasians with type 2 diabetes.
