X-chromosomal short tandem repeats (ChrX STRs) loci are used for forensic practice in recent years. Considering the unique heredity characteristics of ChrX, recombination and linkage disequilibrium (LD) among ChrX STR loci vary between male and female and different populations as well. However, there is a lack of data for analysis of recombination and(More)
Single-nucleotide polymorphisms (SNPs) in pre-miRNAs may alter microRNA (miRNA) expression levels or processing and contribute to susceptibility to a wide range of diseases. We investigated the correlation between four SNPs (rs11614913, rs3746444, rs2910164, and rs229283) in pre-miRNAs and the risk of asthma in 220 asthma patients and 540 controls using(More)
The aim of the study was to evaluate the association of CYP1A1 and CYP1B1 polymorphisms with uterine leiomyoma in Chinese women. We investigated 100 women with clinically diagnosed uterine leiomyoma and 110 healthy normal subjects from Chinese women. The genetic distribution of two CYP1A1 polymorphisms at MspI, Ile462Val and four CYP1B1 polymorphisms at(More)
Tumor necrosis factor (TNF) is an immunomodulatory cytokine that plays an important role in many inflammatory and autoimmune diseases. We investigated the correlation between single-nucleotide polymorphisms of the TNF gene [i.e., TNF-α (308), TNF-α (857), TNF-α (863), TNF-α (1031), and TNF-ß (+252)] and dilated cardiomyopathy (DCM). A total of 110 DCM(More)
Microvariants of short tandem repeat (STR) have been reported for different commercially available multiplex STR systems. Sequence length variations caused by variant mechanisms were the central cause of these abnormal phenomena. Here, we reported a novel electrophoretic mobility of the variant allele 13 of D10S2325 in the Investigator HDplexTM Kit, which(More)
The single nucleotide polymorphisms on the Y chromosome (Y-SNP) have been considered to be important in forensic casework. However, Y-SNP loci were mostly population specific and lacked biallelic polymorphisms in the Asian population. In this study, we developed a strategy for seeking and genotyping new Y-SNP markers based on both Pyrosequencing and the(More)
OBJECTIVE To obtain population genetic data of loci D11S4951, D11S4957, GATA193H05, D2S2951, and D6S2421 in Han population in Chengdu area and to validate the value of their forensic application. METHODS Blood samples were collected in EDTA tubes from unrelated individuals. DNAs were extracted with Chelex-100 and were analyzed by PCR and horizontal PAGE(More)
OBJECTIVE To formulate recommendations in the evaluation of results of genetic analyses in paternity testing under considering mutations. METHODS A total of 15 short tandem repeat(STR) loci were employed for this study, which were included CSF1PO, FGA, TH01, TPOX, VWA, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D21S11, PentaD and PentaE.(More)
Haplotype is a lineable combination of alleles at multiple loci that are transmitted together on chromosome or mitochondrion. In October 2002, the international HapMap project started and aimed at mapping the haplotype blocks of human being and discovering the Tag SNPs by determining the DNA sequence variation patterns, variation frequency and their(More)
