    Abstract:

    OBJECTIVE: To explore whether Val279Phe single nucleotide polymorphisms (SNPs) in the 9th exon of platelet-activating factor acetylhydrolase (PAF-AH) are associated with intracranial hemorrhage in preterm infants. METHODS: A case-control study was performed. Polymerase chain reaction (PCR) was used to test genotype and allele frequencies of the 9th exon Val279Phe SNPs of PAF-AH in 58 preterm infants with intracranial hemorrhage (hemorrhage group) and 65 preterm infants without intracranial hemorrhage (control group). RESULTS: There were significant differences in genotype frequency of Val279Phe SNPs in the 9th exon of PAF-AH between the hemorrhage and control groups (P<0.05). Frequency of normal genotype in the hemorrhage group (63.8%) was significantly lower than in the control group (81.5%). In contrast, frequency of heterozygous genotype (34.5%) in the hemorrhage group was significantly higher than in control group (16.9%). There were also significant differences in allele frequency of Val279Phe SNPs in the 9th exon of PAF-AH between the two groups (P<0.05). T allele frequency in the hemorrhage group (19.0%) was significantly higher than in the control group (10.0%). CONCLUSIONS: Val279Phe SNPs in the 9th exon of PAF-AH may be associated with intracranial hemorrhage in preterm infants.
