Relationship between the 5'UTR of vascular endothelial growth factor polymorphism and retinopathy of prematurity in Chinese premature newborns.

ABSTRACT: OBJECTIVE:To investigate the relationship between vascular endothelial growth factor (VEGF) gene polymorphisms and Retinopathy of prematurity (ROP) development in preterm infants of China Han ethnic population. METHODS:VEGF gene promoter polymorphisms (-165C/T and -141A/C) were studied in 54 neonates with ROP but not requiring treatment (regressive ROP group), 48 neonates with ROP that requires cryotherapy/photocoagulation (severe ROP group), and in a control group of 62 preterm infants without ROP. Genotyping for VEGF gene promoter was performed by polymerase chain reaction (PCR) and gene sequencing. RESULTS:In this study, -165C/T genotype was found to be associated with severe ROP (P=0.012<0.05), but not with regressive ROP. For the dominant genetic model, subjects carrying the -165T all
