Low MBL-conferring genotypes (LXA/O + O/O) were associated with paediatric sepsis.
Low serum MBL, ficolin-2 and -3 on admission were associated with paediatric sepsis.
Low ficolin-3 seemed to be associated with higher mortality from neonatal sepsis.
No impact of SNPs of FCN1, FCN2, FCN3, MASP1/3, MASP2, TLR2, TLR4 genes was found.
