BACKGROUND: The E23K variant of the KCNJ11 gene is possibly responsible for changes in insulin secretion during the fetal life. We tried to assess the influence of the E23K variant on birth weight and metabolic profile in prepubertal children born small for gestational age (SGA).
SUBJECTS: One hundred and twenty-three SGA and 132 born appropriate for gestational age (AGA) children were genotyped for the E23K variant. Lipids, glucose, and insulin concentrations during oral glucose tolerance test were assessed in 112 SGA prepubertal children.
RESULTS: There were no significant differences between the frequency of the E23K variant in SGA and AGA children. In SGA children with E23K, the mean birth weight was significantly higher than in the E23E group. Body mass index, glucose, insulin, and lipids were not different between the E23K, E23E, and K23K groups.
CONCLUSIONS: The higher birth weight in SGA children with the E23K variant may be related to higher insulin concentrations in the fetal period. The E23K variant did not affect metabolic disorders in prepubertal SGA children.
