PURPOSE: The aim of our study was to evaluate the IGF2 and IGF2R plasmatic level and IGF2-ApaI polymorphism on infants with intrauterine growth restriction (IUGR).
MATERIALS AND METHODS: A transversal study was conducted at the Neonatology Ward of the Gynecology Clinic I, Emergency Hospital Cluj-Napoca on neonates with IUGR who were discharged during June 2014 and June 2015. The serum levels of IGF2 and IGF2R were obtained by using ELISA method and IGF2-ApaI polymorphism by taking PCR-RFLP analysis.
RESULTS: Forty infants with IUGR and 21 infants of appropriate gestational age (AGA) were evaluated. The serum levels of IGF2 proved higher on the A/G genotype when the IUGR group was compared with AGA (p value = .048). The G allele proved significantly more frequent in both the IUGR and the AGA group compared with the A allele (p < .002). Neither any allele nor any genotype proved a risk factor for IUGR (p value > .3). The A/G genotype proved significantly more frequent on term infants compared with preterm infants (p value = .039).
CONCLUSIONS: The infant with IUGR has a higher serum level of IGF2 if has A/G IGF2-ApaI genotype and higher values of IGF2R if it has the A/A genotype.
