Association of rs 3807337 polymorphism of CALD1 gene with diabetic nephropathy occurrence in type 1 diabetes - preliminary results of a family-based study.

The worldwide growing burden of diabetes and end-stage renal disease due to diabetic nephropathy has become the reason for research looking for a single marker of chronic kidney disease development and progression that can be found in the early stages of the disease, when preventive action delaying the destructive process could be performed. The aim of the study was to investigate the influence of rs3807337 polymorphism of the caldesmon 1 (CALD1) gene located on the long arm of chromosome 7 encoding for protein that is connected with physiological kidney function on development of diabetic nephropathy. There was an association study of rs3807337 polymorphism of the CALD1 gene in parent-offspring trios by PCRRFLP method. Ninety-nine subjects: 33 patients with diabetic nephropathy due to type 1 diabetes and 66 of their biological parents, were examined. The mode of alleles transmission from heterozygous parents to affected offspring was determined using the transmission disequilibrium test. The allele G of rs3807337 polymorphism of the CALD1 gene was transmitted to affected offspring significantly more often than expected for no association. The obtained results suggest that the genetic variability of the CALD1 gene may influence the development of diabetic nephropathy in type 1 diabetes, but further studies involving larger studied groups of patients are needed.
