The result of uroscopy of the proband was strong positive. There was a novel deletion mutation of c.876-877 del TC in the coding region of exon 6 of IDS gene, which was a hemizygous mutation. However, the mutation of his mother and sister was a heterozygous mutation. Detection of the exon 6 of IDS gene showed that the mutation was not found among normal controls and other patients with MPS I, IV, and VI other than MPS II. Homology comparison of amino acid sequences from different species showed that the phenylalanine glutamine of the mutation site of c.876-877 del TC located in p.292-293 was highly conserved. The activity of IDS enzyme of the proband was only 2.3 nmol/4 h/mL, which was much lower than normal; but the activity of IDS enzyme of his father, mother and sister was 641.9 nmol/4 h/mL, 95.8 nmol/4h/mL and 103.2 nmol/4h/mL, respectively.

结果显示：先证者尿检呈强阳性；其IDS基因exon 6编码区内存在c.876-877 del TC新缺失突变，为半合子突变，而其母、其姐为杂合突变；正常对照和其他非II型MPS患者的IDS基因exon 6的检测结果均未发现该突变；不同物种氨基酸序列的同源性比对显示： c.876-877 del TC突变所在的位置即p.292-293的苯丙氨酸谷氨酰胺高度保守；酶活性测定的结果显示：先证者的IDS酶活性仅为2.3 nmol/4 h/mL，大大低于正常值，而其父的为641.9 nmol/4 h/mL，其母的血浆酶活性为95.8 nmol/ 4h/mL，其姐的为103.2 nmol/4 h/mL。

The CryCI gene and essential regulation elements cut from the plasmid pGF4ABC were inserted into yeast expression vector pPIC9K and plant expression vector pBI 121.1, so we got the secretive yeast expression plasmid pPIC9KBC and plant high-efficiency expression plasmid pGBIF4ABC, Fifty-two His+Muts transformants were obtained after the expression vector pPIC9KBC was introduced into Pichia pasoris, KM7I strain, by electroporation.

It was known that ORF of SeMNPV egt was 1572bp long and encodes 523 amino acids through DNAstar software analysis. TATA boxes lies at 48~53 and 68~72bp of the 5'-nonencoding region upstream of a translational start site. Comparing with seven kinds of nuclear polyhedrosis virus and one kind of granulosis virus, it indicated that the SeMNPV egt gene is the highest match the Agrotis setegum nuclear polyhedrosis virus.It has 75% nucleotides and 79% amino acid identity.

Pneumoniae FH strain was cloned and the sequence was analysed by M13 DNA sequencing method. Comparing the PCR product sequcence with MP M-129 strain P1 gene, we found that there are 4 bases different. This may result from the different MP DNA templates. The maximum homology is 98.8%. The result confirmed the fidelity and specificity of the amplified target DNA segment by PCP, and suggested that two categories of MP P1 gene still exist a few differences even in the conservation region. The cloning MP DNA segment was labelled by random hexanucleotide priming, after hybridization, the probe detection was completed using an anti-digoxigenin antibody alkaline phosphatase conjugate, and the substrates 5-bromo-4-chloro-3-indolyl phosphate and nitro blue tetrazolium. This hybridization system is much superior to the radioactive probe hybridization, because it is safe, easy to handle and has no limitation of decay time. The time required for colormetic detection is also much less than the corresponding autoradiographic exposure time needed to achieve similar detection limits with 32P-labelled probes. The Dig-probes could be used repeatedly, and this made them not only much convenient to use, but also lower the cost, and worthwhile to be used popularly.
