Abstract
Background: Retinopathy of prematurity (ROP) is an important cause of preventable blindness in children. The aim of this study was to examine the association of the polymorphisms at Factor V Leiden (FVL) and methylene tetrahydrofolate reductase (MTHFR) gene with risk of ROP.
Methods: A total of 106 neonates with ROP and 110 healthy neonates were enrolled. The FVL G1691A and MTHFR C677T and A1298C polymorphisms were genotyped by PCR-RFLP assay.
Results: There was a significant association between FVL G1691A polymorphism and an increased risk of ROP. However, the MTHFR C677T and A1298C polymorphisms were not associated with risk of ROP.
Conclusion: FVL G1691A polymorphism may be risk factor for development of ROP in neonates. However, there was no significant association between MTHFR C677T and A1298C polymorphisms and risk of ROP. However, it is critical that larger and well-designed studies in different ethnicities are needed to confirm our conclusions.
