We studied the association between 43 pathway-related candidate genes with 'intermediate phenotype' (i.e. corresponding plasma protein) and diabetic nephropathy in a customised microarray of 1,536 SNPs. Methods: In this case-control study of type 2 diabetic Chinese individuals with and without diabetic nephropathy, cases (n∈=∈545) were defined on the basis of a spot urinary albumin/creatinine ratio (ACR)∈>∈113 mg/mmol; the value for controls (n∈=∈503) was ACR∈A, frequency∈=∈0. 252) was correlated with plasma C-terminal pro-endothelin-1 concentrations with an estimated OR for diabetic nephropathy of (heterozygous) 1.26 (0.96-1.66) and (homozygous) 1.87 (1.13-3.12) (p∈=∈0.0072). Nitric oxide synthase 1 (NOS1) 5′ haplotype (TGTC frequency∈=∈0.38) also revealed a suggestive association with diabetic nephropathy: heterozygous 1.26 (0.95-1.67), homozygous 1.57 (1.04-2.35) (p∈=∈0.0073). A rare NADPH oxidase homologue 1 (NOX1)-coding non-synonymous SNP (Arg315His, frequency∈= ∈0.006) was found exclusively among cases. Conclusions/interpretation: Our preliminary observations suggest that common haplotypes from NOX4 and endothelin-1 SNP correlated with plasma Cu/Zn SOD and C-terminal pro-endothelin-1 concentrations, respectively, and might have conferred diabetic nephropathy susceptibility. Common NOS1 and rare NOX1 variants also revealed a suggestive association with diabetic nephropathy. Future studies to validate our observation are needed. © 2009 Springer-Verlag.||Source Title:||Diabetologia||URI:||http://scholarbank.nus.edu.sg/handle/10635/108466||ISSN:||0012186X||DOI:||10.1007/s00125-009-1368-x|
