Methods For 4 patients with FH detected by PCR SSCP and DNA sequence analysis (1 homozygote has point mutation in exon 7, 1 heterozygote in exon 14,and 2 heterozygotes in 3′ part of exon 4 ),members of each pedigree, altogether 23 individuals,were analysed using PCR SSCP.
Objective:To investigate mutational spectra of Ki-ras gene exons 1,2 and p53 gene exons 7,8 in patients with lung squamous cancer and lung adenocarcinoma and to look into prognosis of patients with Ki-ras or p53 mutation and with no mutation.
Results A total of 37 SMA patients and 20 cases of the normal controls and 20 cases of the SMA patients' parents were analyzed. The exons 7 and 8 of SMN gene were found to be deleted in 92%(34/37) and 89%(33/37) patients respectively.
One targeted ES clone was found by Southern blot and PCR to have 2 flanking loxP of exons 7 and 8. Conclusion The ES clones with FGFR2 conditional knockout were established successfully.
Methods: We detected the MI in 45 cases of bladder carcinoma by polymerase chain reaction using microsatellite markers such as D2S119 and D2S123. We also analyzed the mutation of hMSH2 gene exons 7, 8, 15 in the MI cases by using polymerase chain reaction single strain conformation polymorphism (PCR SSCP) silver staining analysis.
There were no significant difference of p53 mutations or p53 protein respectively between cervical cancer and dysplasia (mutation: P >0.9;expression: P >0.1).
We select two cSNP as genetic markers of GDI1. One is rsll549300 SNP in eighth extron of GDI1 gene, the other is rs2276462 SNP in seventh extron of GDI1 gene.
Molecular genetic analysis of the I462V mutation in exon 7 of the CYP1A1gene demonstrated close similarity between the genotype and allele frequency distribution patterns in the industrial and control groups.
Nucleotide and deduced amino acid sequences of two cloned FLC fragments (from exon 2 to exon 7) were compared to the previously characterized FLC genes in arabidopsis and FLC homologs in other Brassicaceae species.

We have detected a hitherto undescribed 2.5-kb deletion, which mapped to the central region of the gene, and most likely includes all of exons 7 and 8.

Exon 3 termination mutation of phenylalanine hydroxylase (PAH) gene, the only identified one causing classical phenylketonuria (PKU) in Chinese, was detected in fourteen PKU children from Xi'an. The genomic DNA from these patients was amplified by polymerase chain reaction(PCR) and dot hybridied with specific oligonucleotide probes. This mutation is not present in any of these affected children, which indicates that phenylketonuria in Chinese may be caused by other mutations in phenylalanine hydroxylase loc...
Applying recombinant DNA techni- ques,the structures of red pigment gene(RPG)and green pigment gene(GPG)were analyzed for 43 pa- tients with protan or deutan(including 3 females),4 normal reladves and 3 carriers out of 3 families,as well as 11 normal controls.Abnormality of RPG was detected in all 19 protan and that of GPG was found in 14 out of 24 deutan.In about 80%(32/40) of protan and deutan the changing of exon 5 for RPG or GPG was discovered.In protan the normal RPG was replaced by a 5' red —3' green ...
In this paper,we analyse Xba I/FⅧ_(E22)RFLP in the population of Suzhou usinga intragenic factor Ⅷ cDNA probe FⅧ_(E22).The results show 9.6/4.8 K b poly-morphism,and their frequency are 0.36/0.64 respectively.The value of PIC is 0.46Based on this polymorphism,carrier detection of hemophilia A was performed.
