ABSTRACT
Purpose: To evaluate the association of intercellular cell-adhesion molecule 1 (ICAM-1) and high-mobility group A1 (HMGA1) gene variants with diabetic retinopathy (DR) in a Chinese type 2 diabetes mellitus (T2DM) cohort.
Methods: A total of 792 patients with T2DM were enrolled and categorized into two groups: (1) the DR group consisted of 448 patients, which was further subclassified into the proliferative DR (PDR) group with 220 patients and the nonproliferative DR (NPDR) group with 228 patients; (2) the diabetes without retinopathy (DNR) group comprised 344 patients who had no signs of DR. The single-nucleotide polymorphism (SNP) rs5498 in ICAM-1 gene and IVS5-13insC variant in HMGA1 gene were genotyped.
Results: No evident association was found in the allele frequencies between SNP rs5498 in ICAM-1 gene and DR patients; the combined p values for the additive, dominant, and recessive models in genotype were greater than 0.05. No significant association was identified between the IVS5-13insC variant in HMGA1 gene and DR individuals.
Conclusions: Our results revealed that SNP rs5498 in ICAM-1 gene and IVS5-13insC variant in HMGA1 gene were not associated with the susceptibility of DR in the Chinese T2DM cohort.
