Abstract

The aim of the present study was to investigate the association of neonatal necrotizing enterocolitis (NEC) with myeloid differentiation‑(MD‑2) and GM2 activator protein (GM2A) genetic polymorphisms. Gene resequencing of the MD‑2 and GM2A gene exons was performed on 42 neonates, diagnosed with NEC (NEC group), as well as in the rs11465996 locus, located in the MD‑2 gene promoter region. The aim was to detect the genetic polymorphisms present in the neonates with NEC and compare the functional polymorphic loci with 83 neonates without NEC (control group), who had been born during the same period. A polymorphic locus with abnormal frequency was detected in the exon region of the MD‑2 gene. In the NEC group, the frequency of genotypes carrying the low frequency allele (G) in the rs11465996 locus (MD‑2 promoter region) was significantly higher compared with the control group (χ2=4.388, P=0.036). Furthermore, the frequencies of genotypes carrying the low frequency A and C alleles in the rs1048719 (GM2A gene exon 1) and rs2075783 loci (GM2A intron), respectively, were significantly higher in the NEC group compared with the control group (χ2=4.316, P=0.038; and χ2=13.717, P=0.000, respectively). In addition, the rs11465996 polymorphism in the MD‑2 gene promoter region was found to be associated with the severity of NEC. Furthermore, the rs2075783 polymorphism in the GM2A gene exon 1 and the rs1048719 polymorphism in the intron region of this gene, were associated with the occurrence of NEC. The present study demonstrated that gene polymorphisms of MD‑2 and GM2A were associated with the occurrence or severity of NEC; however, further in‑depth exploration is required to clarify the associations between genetic predispositions to polymorphisms, and NEC.
