Abstract:
Objective To study the correlation between the surfactant protein C ( SP-C) gene mutation in exon 5 area and respiratory distress syndrome(RDS) in premature infants. Methods From January 2013 to January 2015, nonconsanguineous premature infants [28 weeks ≤gestational age(GA)< 37 weeks] of Han ethnicity with RDS admitted to our hospital were selected as the RDS group, and nonconsanguineous Han premature infants without RDS as the control group. SP-C gene exon 5 mutation were detected using the gene sequencing method. Results SP-C gene exon 5 region c. 715G > A heterozygous mutations were detected in 17 cases among 60 patients in the RDS group. The mutation frequency was 28. 3% . SP-C gene exon 5 region c. 715G > A heterozygous mutations were detected in 8 cases among 60 patients in the control group. The mutation frequency was 13. 3% . The mutation frequency in the RDS group was statistically significantly higher than the control group (χ2 = 4. 093,P =0. 043) . In RDS group, c. 715G > A heterozygous mutation had no significant correlation with RDS grades, oxygen therapy, pulmonary surfactant dose nor treatment outcome (P > 0. 05). Conclusions A correlation may be existed between SP-C gene exon 5 area c. 715G > A heterozygous mutation and RDS in premature infants.
