Background: As described in animal models, the lectin- complement pathway is central to the propagation of ische- mia–reperfusion injuries in many tissues, including the brain. Similarly, it might affect the genesis of brain damage in pre- term infants. MBL2 gene single-nucleotide polymorphisms (SNPs), regulating mannose-binding lectin (MBL) serum levels, could predict the risk of adverse neurological outcome in these infants. Methods: To evaluate the association between SNPs of the MBL2 gene and long-term neurological outcomes in preterm infants,75infants(gestationalage(GA)≤32 wk)were observed in a prospective longitudinal study and assessed by clinical and instrumental exams at 12 and 24 mo of corrected age (CA). They were genotyped for the promoter polymorphism -221 and for the exon-1 variant alleles (at codons 52, 54, and 57) of the MBL2 gene. results: The MBL2 exon-1 OO genotype was more frequent in children with an adverse neurological outcome (5/35; 7%) than in controls (0/40; 0
