Role of 19 SNPs in 10 genes with type 2 diabetes in the Pakistani population.

Meta-GWAS report numerous variants associated with type 2 diabetes (T2D), however, for diabetic retinopathy (DR) no loci achieved genome-wide significance. There are limited candidate gene analyses for T2D and/or DR reported from the Pakistani population. Therefore, the current study was designed to evaluate the genetic association of 10 loci with T2D, non-proliferative DR (NPDR), and proliferative DR (PDR).

Association of rs10490924 in ARMS2/HTRA1 with age-related macular degeneration in the Pakistani population.

Age-related macular degeneration (AMD) is a disease of the elderly in which central vision is lost because of degenerative changes of the macula. The current study investigated the association of single-nucleotide polymorphisms (SNPs) with AMD in the Pakistani population. Four SNPs were analyzed in this study: rs1061170 in the CFH, rs429608 near CFB, rs2230199 in the C3, and rs10490924 in ARMS2/HTRA1.

Role of ACE and PAI-1 Polymorphisms in the Development and Progression of Diabetic Retinopathy.

In the present study we determined the association of angiotensin converting enzyme (ACE) and plasminogen activator inhibitor-1 (PAI-1) gene polymorphisms with diabetic retinopathy (DR) and its sub-clinical classes in Pakistani type 2 diabetic patients. A total of 353 diabetic subjects including 160 DR and 193 diabetic non retinopathy (DNR) as well as 198 healthy controls were genotyped by allele specific polymerase chain reaction (PCR) for ACE Insertion/Deletion (ID) polymorphism, rs4646994 in intron 16 and PAI-1 4G/5G (deletion/insertion) polymorphism, rs1799768 in promoter region of the gene. To statistically assess the genotype-phenotype association, multivariate logistic regression analysis was applied to the genotype data of DR, DNR and control individuals as well as the subtypes of DR.

Association of Pro12Ala polymorphism in peroxisome proliferator activated receptor gamma with proliferative diabetic retinopathy.

Purpose: The association of non-synonymous substitution polymorphism rs1801282 (c.34C>G, p.Pro12Ala) in exon 4 of the peroxisome proliferator activated receptor gamma gene with diabetic retinopathy (DR) has been reported inconsistently.
