OBJECTIVE To examine the correlation of lactase persistence phenotype with genotype in Omani adults. METHODS Lactase persistence phenotype was tested by hydrogen breath test in 52 Omani Adults using the Micro H2 analyzer. Results were checked against genotyping using direct DNA sequencing. RESULTS Forty one individuals with C/C-13910 and T/T-13915 genotypes had positive breath tests (≥20 pp...

For some applications, such as genome sequencing and high-throughput genotyping with multiple markers, it is necessary to use high-quality genomic DNA. This article describes how to obtain several micrograms of high-quality, cesium chloride-purified DNA from 1 g of Ectocarpus filaments. We also recommend using DNA of this quality for quantitative RT-PCR control reactions. However, simpler, more...

background: the high resolution melting (hrm) method is a new scanning method for detecting unknown changes in dna and its advantages have persuaded researchers to recruit it as a screening method. objectives: here, we developed a hrm method to screen r188h snp (rs3218536) of xrcc2 and compared the results with a well known pcr-rflp technique. materials and methods: genomic dna samples from 350...

Background: Myasthenia gravis (MG) is the most common disorder of neuromuscular junction in which autoantibodies develop against nicotinic acetylcholine receptor for unknown reasons. The association of immunomodulator genes with different autoimmune disease has been studied in recent years. Objective: The aim of this study was to investigate correlation between a genetic variation in Stromal Ce...

PURPOSE The HDM2 gene represents one of the central nodes in the p53 pathway. A recent study reported the association of a single nucleotide polymorphism (SNP309) in the HDM2 promoter region with accelerated tumor formation in both hereditary and sporadic cancers. In this study, we aim to evaluate the SNP309 in bladder cancer and to link it to TP53 status. EXPERIMENTAL DESIGN SNP309 genotypin...

Background: The pathogenesis of migraine involves immune-mediated mechanisms in the vascular endothelium. Toll like receptor 4 (TLR-4) is a signaling receptor of innate immunity which plays a role in various neuropathologies related to neuron inflammation. Objective: This case/control study is aimed to investigate whether TLR- 4 896A/G variation is related to migraine headaches in an Iranian po...

diacylglycerol acyltransferase1 (dgat1) is a key enzyme in synthesis of triglycerides. a transition mutation resulting substitution of guanine by adenine in dgat1 gene and substitution of lysine by alanine in diacylglycerol-acyltransferase enzyme in cattle has a major effect on milk yield and milk composition traits. in this research, the polymorphism of the region spanning exon 3 to exon 17 of...

conclusions the present clinical study suggests that the transmission of an hbv genotype other than genotype d, namely hbv genotype g, is possible in turkey. epidemiological and clinical information on genotype g infection is currently limited, and this is most likely due to its low prevalence throughout the world. therefore, it may be important to determine the epidemiologic and molecular char...

To make large-scale association studies a reality, automated high-throughput methods for genotyping with single-nucleotide polymorphisms (SNPs) are needed. We describe PCR conditions that permit the use of the TaqMan or 5' nuclease allelic discrimination assay for typing large numbers of individuals with any SNP and computational methods that allow genotypes to be assigned automatically. To dem...
