[Polymorphic gene markers of lipid metabolism are associated with diabetic nephropathy in patients with type 1 diabetes mellitus].Genetika. 2005 Jul; 41(7):931-7.G
In groups of type 1 diabetes mellitus patients with and without clinical signs of diabetic nephropathy (n = 62 and n = 68, respectively), a search was made for associations between diabetic nephropathy and the polymorphic marker epsilon2/epsilon3/epsilon4 of apolipoprotein E gene (APOE), I/D marker of apolipoprotein B gene (APOB), and Ser447Ter marker of lipoprotein lipase-encoding gene (LPL). The risk of diabetic nephropathy was higher in the carriers of allele epsilon3 and genotype epsilon3/epsilon3 of the polymorphic marker epsilon2/epsilon3/epsilon4 of APOE gene as well as in the carriers of allele 1 and APOB genotype/gene (OR = 2.08 and 2.16; 1.91 and 2.11, respectively). Conversely, the carriers of allele D showed a reduced risk of this complication (OR = 0.52). No significant differences in distribution of alleles and genotypes of the polymorphic marker Ser447Ter of LPL gene were found between the groups. Our results indicate that the genes encoding two major components of lipid metabolism are involved in the development of diabetic nephropathy in patients with type 1 diabetes mellitus.
