Association of CFH and CFB gene polymorphisms with retinopathy in type 2 diabetic patients.

ABSTRACT:

Objectives

The complement system is a key component of innate immunity and has been implicated in the pathogenesis of diabetic retinopathy (DR). This study aimed at investigating whether polymorphisms of two genes in the complement pathway, complement factor H (CFH) and complement factor B (CFB), are associated with DR.

Methods

552 well-defined subjects with type 2 diabetes, consisting of 277 DR patients and 275 diabetic controls, were recruited. Four Tag-SNPs rs1048709, rs537160, rs4151657, and rs2072633 in CFB and rs800292 (I62V) in CFH were examined using TaqMan Genotyping Assays.

Results

There were significant increases in the frequencies of A allele and AA genotype for rs1048709 in DR patients compared with diabetic controls (P(corr) = 0.035, OR = 1.42; P(corr) =
