Association of kinase insert domain-containing receptor (KDR) gene polymorphisms with idiopathic recurrent spontaneous abortion in Korean women

An association between the KDR -604T→C polymorphism and RSA was found in Korean women. Carriers of the -604C variant allele were more frequent among RSA patients than among controls, suggesting that KDR -604C may confer RSA risk. The association of 1719A→T with RSA that was found in Taiwanese Han women was not observed in Korean women.
