Title: [Detection of a new mutation (G1253T) of iduronate-2-sulfatase gene for the patient with mucopolysaccharidosis type II]. Author: Zhang CY, Li LY, Liu SF, Fu JJ, Lu GX. Journal: Zhonghua Yi Xue Yi Chuan Xue Za Zhi; 2004 Jun; 21(3):269-71. PubMed ID: 15192834. Abstract: OBJECTIVE: To identify the mutations of iduronate-2-sulfatase (IDS) gene in mucopolysaccharidosis type II patients. METHODS: PCR-SSCP analysis was applied to detect the common mutations in the exons 2, 3, 5, 7, 8, 9 in IDS-gene of the patient. DNA sequencing and PCR-RFLP were applied to analyze the mutation detected by PCR-SSCP. RESULTS: A new mutation(1253G-->T) of exon 7 of the IDS gene was found by PCR-SSCP and DNA sequencing in the patient, The PCR-restriction enzyme digestion showed that enzyme digestion location appeared in the patient and his mother, which verified the results of sequencing analysis. CONCLUSION: The mutation of patient with MPSII could be detected effectively and quickly by the applications of PCR-SSCP, DNA sequencing and PCR-restriction enzyme digestion analysis, and the new mutation thus detected is necessary for the prenatal diagnosis of the pedigree.[Abstract] [Full Text] [Related] [New Search]
