title: [Association of CYP2E1 of PON2311 polymorphisms in neonates with preterm].
abstract: The objective is to investigate whether Rsa I polymorphism in the 5'-flanking region of CYP2E1 and PON2311 polymorphism in neonates are associated with preterm. Using standard questionnaires, 194 singleton live born mother-neonate pairs (including preterm cases and term controls) were investigated by the trained field workers with cross-sectional survey at the hospitals in Anqing, Anhui Province, China. Epidemiological and clinical data and blood samples were obtained from 194 mother-neonate pairs. CYP2E1 homozygous wild-type (cut/cut) is not associated with a shortened gestation among neonates, compared with CYP2E1 homozygous mutant-type (uncut/uncut)/CYP2E1 heterozygote (cut/uncut) before and after adjustment confounders. However, PON2 Ser311Ser homozygote is significantly associated with a shortened gestation among neonates. When Rsa I polymorphism in the 5'-flanking region of CYP2E1 and PON2311 polymorphism were considered jointly, a significant shortened gestation was observed among neonates with the combined genotype of CYP2E1 homozygous wild-type and PON2 Ser311Ser homozygote. In conclusion, Rsa I polymorphism in the 5'-flanking region of CYP2E1 in neonates is not associated with preterm, however, PON2311 polymorphism in neonates is significantly associated with preterm. Furthermore, the gene interaction between Rsa I polymorphism in the 5'-flanking region of CYP2E1 and PON2311 polymorphism in neonates is significantly associated with preterm.
