We evaluated 21 single-nucleotide polymorphisms (SNPs) in 17 genes associated with neuronal homeostasis, neuroprotection, or oxidative stress in umbilical cord blood. Cases included infant deaths (n=43) and children with cerebral palsy (n=24), mental delay (Bayley Mental Developmental Index less than 70; n=109), or psychomotor delay (Bayley Psychomotor Developmental Index less than 70; n=91) diagnosed. Controls were race-matched and sex-matched children with normal neurodevelopment. Associations between each SNP and each outcome were assessed in logistic regression models assuming an additive genetic pattern, conditional on maternal race and infant sex, and adjusting for study drug assignment, gestational age at birth, and maternal education.Abstract: RESULTS: The odds of cerebral palsy were increased more than 2.5 times for each copy of the minor allele of vasoactive intestinal polypeptipe (VIP, rs17083008) (adjusted odds ratio 2.67, 95% confidence interval 1.09-6.55, P=.03) and 4.5 times for each copy of the minor allele of N-methyl-D-aspartate receptor subunit 3A (GRIN3A, rs3739722) (adjusted odds ratio 4.67, 95% CI 1.36-16.01, P=.01). The association between the advanced glycosylation end product-specific receptor (AGER, rs3134945) SNP and mental delay was modulated by study drug allocation (P=.02).Abstract: CONCLUSION: Vasoactive intestinal polypeptipe and GRIN3A SNPs may be associated with cerebral palsy at age 2 in children born preterm.
