© 2014 The Authors. Hepatitis C virus (HCV) exhibits high genetic diversity, characterized by regional variations in genotype prevalence. This poses a challenge to the improved development of vaccines and pan-genotypic treatments, which require the consideration of global trends in HCV genotype prevalence. Here we provide the first comprehensive survey of these trends. To approximate national HCV genotype prevalence, studies published between 1989 and 2013 reporting HCV genotypes are reviewed and combined with overall HCV prevalence estimates from the Global Burden of Disease (GBD) project. We also generate regional and global genotype prevalence estimates, inferring data for countries lacking genotype information. We include 1,217 studies in our analysis, representing 117 countries and 90% of the global population. We calculate that HCV genotype 1 is the most prevalent worldwide, comprising 83.4 million cases (46.2% of all HCV cases), approximately one-third of which are in East Asia. Genotype 3 is
The diagnosis of mixed genotype hepatitis C virus (HCV) infection is rare and information on incidence in the UK, where genotypes 1a and 3 are the most prevalent, is sparse. Considerable variations in the efficacies of direct-acting antivirals (DAAs) for the HCV genotypes have been documented and the ability of DAAs to treat mixed genotype HCV infections remains unclear, with the possibility that genotype switching may occur.. In order to estimate the prevalence of mixed genotype 1a/3 infections in Scotland, a cohort of 512 samples was compiled and then screened using a genotype-specific nested PCR assay. Mixed genotype 1a/3 infections were found in 3.8% of samples tested, with a significantly higher prevalence rate of 6.7% (p,0.05) observed in individuals diagnosed with genotype 3 infections than genotype 1a (0.8%). An analysis of the samples using genotypic-specific qPCR assays found that in two-thirds of samples tested, the minor strain contributed ,1% of the total viral load. The potential ...
Hepatitis C virus (HCV) genotype and other host and viral factors influence treatment outcome in chronic HCV infection. We evaluated the effect of race and genotype on interferon and ribavirin treatment outcome in 70 Southeast Asian (SEA) and 50 white patients. Genotype was based on the 5 untranslated region (5UTR) with a commonly used line probe assay (INNO-LiPA HCV II) that may mistype genotype 7, 8, or 9 as 1b. HCV core region sequencing resulted in reclassification of 8 genotype 1 and 25 genotype 1b SEA subjects as genotype 7, 8, or 9. Twenty-six SEA genotype 7, 8, and 9 (79%) and 10 SEA true genotype 1b (59%) patients achieved a sustained virologic response (SVR) compared with 15 (34%) white genotype 1b patients. Logistic regression analysis showed that SEA patients with genotype 7, 8, or 9 were more likely to achieve a SVR than white genotype 1b patients (OR 16.56; 95%CI 4.16, 65.91) as were SEA true genotype 1b patients compared with white genotype 1b patients (OR 4.63; 95%CI 1.19, ...
The goal of the present study was to examine the hypothesis of the physical association of multiple genotypes in a single OB for the maintenance of virus diversity. Previous studies have demonstrated that during the systemic phase of infection, single cells in an insect can be co-infected by multiple BV particles, each carrying a single genotype (Godfray et al. 1997; Bull et al. 2001). To maintain genetic diversity during between-host transmission, it is necessary that the larva acquire different genotypes at the moment of primary infection. As the number of OBs required to kill a larva is usually low, the occurrence of multiple genotype infection would be improbable for highly susceptible larvae that can be infected by a single or very few OBs. Under these conditions, maintaining diversity within a larva could be compromised if genotypes are segregated among different OBs, except perhaps during the course of an epizootic, when unusually high densities of OBs may be present briefly in the ...

Background: Hepatic steatosis in HCV patients has been postulated as a risk factor associated with a higher frequency of fibrosis and cirrhosis. A single genetic variant, PNPLA3 I148M, has been widely associated with increased hepatic steatosis. Previous studies of the PNPLA3 I148M sequence variant in HCV infected individuals have reported an association between this variant and prevalence of steatosis, fibrosis, and cirrhosis. To evaluate the impact of PNPLA3 I148M variant on metabolic traits and treatment response in HCV genotype 2 and 3 infected patients.. Methods. Three hundred and eighty-two treatment naïve HCV genotype 2 or 3 infected patients were included in a phase III, open label, randomized, multicenter, investigator-initiated trial (the NORDynamIC study), in which pretreatment liver biopsies were mandatory. PNPLA3I148M genotyping was performed in a total of 359 Caucasian patients.. Results: In HCV genotype 2 infected patients carrying the PNPLA3 148M allele, there was significantly ...
For example, there is 70% penetrance if only 700 individuals express red phenotype out of 1,000 HairredHairred individuals. If penetrance of a phenotype is not 100%, then it has reduced penetrance. Mechanisms of reduced penetrance are not always clear. Expressivity is another important concept in describing genotype-phenotype correlation. Expressivity describes the severity of a phenotype among individuals with the same genotype. For example, if a condition has variable expressivity then one individual might have mild symptoms while another might have severe symptoms (although they have the same genotype). If a trait has constant expressivity then individuals with the same genotype will have the same degree of symptoms.. Mechanisms of variable expressivity are not always clear. Although there is typically a clear genotype-phenotype correlation that associates a specific allele with a specific phenotype, this link is frequently muddled. Even individuals with identical genotypes can have different ...
Of the 170 million patients who are chronically infected with HCV worldwide, approximately half have HCV genotypes other than genotype 1, including about one third of patients with HCV in the United States.17 Currently approved regimens of direct-acting antiviral agents are not equally effective across all genotypes, which means that testing to determine genotype and subtype is required before treatment can be initiated.6,7 A single combination regimen that is effective in all patients regardless of HCV genotype would obviate the need for pretreatment testing, which is an obstacle to treatment in resource-limited settings and may limit treatment uptake outside of specialty clinics.18 In this international, randomized, double-blind, placebo-controlled phase 3 study, treatment with sofosbuvir-velpatasvir for 12 weeks resulted in high rates of sustained virologic response in patients with HCV genotype 1, 2, 4, 5, or 6, including those with cirrhosis and those who had received previous treatment and ...
The single-nucleotide polymorphism SLC39A6 rs1050631 is strongly implicated in esophageal squamous cell carcinoma, leading us to question whether it may also play a role in gastric adenocarcima (GA). We genotyped the SLC39A6 rs1050631 in 512 patients who underwent GA resection. All study subjects lived in an area of China with high GA incidence. Genotypes were examined for possible correlation with survival and recurrence. The potential involvement of SLC39A6 in gastric cancer was explored in clinical samples and cell culture studies. Multivariable analysis showed that patients with the CT + TT genotype at SLC39A6 rs1050631 were at greater risk of recurrence (hazard ratio, HR 1.387, p = 0.004) and death (HR 1.429, p = 0.002) than patients with CC genotype. Median recurrence-free and overall survival were significantly shorter in patients with the CT + TT genotype (20, 27 months) than in patients with the CC genotype (36, 43 months, p = 0.001, p | 0.001). Patients with the CT + TT genotype who were male
Supplement The genotype refers to the entire set of genes in a cell, an organism, or an individual. A gene for a particular character or trait may exist in two allelic forms; one is dominant (e.g. A) and the other is recessive (e.g. a). Based on this, there could be three possible genotypes for a particular character. For instance, a genotype of AA delineates homozygous dominance whereas a genotype of Aa is an example of heterozygous dominance. A genotype of aa is an instance of homozygous recessive. The genotype is a major factor that determines the phenotype of an organism. For example, the genotype determines the color of the petal of a pea plant. ...
The shared genotyping facility is expected to increase throughput ten-fold and reduce costs by about 75-80% in comparison to current procedures. Lowering the genotyping cost will enable CGIAR and other public sector breeders to utilize marker-based selection in forward breeding and also change their current breeding procedures to take advantage of low-cost genotyping. It will be then possible to generate several-fold higher numbers of lines and select them with diagnostic markers for key traits before phenotyping, increasing selection intensity for yield and selection accuracy for other traits. This will accelerate genetic gains in CGIAR mandate crops. The genotyping data demand across from all/leading CGIAR Centers can be aggregated, the costs can be brought down in the range of US$ 1-5 per sample (with 10-100 markers). ...
Results. For the CD4 -11743A/C polymorphism, patients with RA demonstrated significantly higher frequency of the C allele (p = 0.048); patients with SLE had significantly higher frequency of the CC genotype (p = 0.026), and lower frequency of the AC genotype (p = 0.013) compared with controls. For the CD4 -10845A/G polymorphism, patients with RA had significantly higher frequencies of the AA genotype (p = 0.047) and the A allele (p = 0.026); patients with SLE had significantly higher frequency of the AA genotype (p = 0.011) and A allele (p = 0.001), and lower frequency of the GG genotype (p = 0.003) compared with controls. A comparison of genotype groups according to different clinical variables revealed the association of the respective polymorphisms with mucosal ulcer lesions among patients with SLE ...
RESULTS: We found that the most prevalent genotype was Apo Eε3/3, followed in order by Apo Eε3/4 and Apo Eε2/2. The estimated ApoE allelic frequencies in individuals with SD were 0.095, 0.560, and 0.345 for ε2, ε3, and ε4, respectively. In controls, the corresponding Apo E allelic frequencies were 0.146, 0.699, and 0.155. The percentage of ε4 allele carriers in SD group was significantly higher than that in control group ( ...
22 Genome-wide association studies of complex traits are often complicated by relatedness 23 among individuals. Ignoring or inappropriately accounting for relatedness often results in 24 inflated type I error rates. Either genotype or pedigree data can be used to estimate relat25 edness for use in mixed-models when undertaking QTL mapping. We performed simulations 26 to investigate methods for controlling type I error and optimizing power considering both 27 full and partial pedigrees and, similarly, both sparse and dense marker coverage; we also ex28 amined real data sets. 1) When marker density was low, estimating relatedness by genotype 29 data alone failed to control the type I error rate; 2) this was resolved by combining both 30 genotype and pedigree data. 3) When sufficiently dense marker data was used to estimate 31 relatedness, type I error was well controlled and power increased; however, 4) this was only 32 true when the relatedness was estimated using genotype data that excluded genotypes on

Recently with the rapid improvements in high-throughout genotyping techniques, researchers are facing the very challenging task of analyzing large-scale genetic associations, especially at the whole-genome level, without an optimal solution. genotype data, it does not require any computationally rigorous phasing program to account for uncertain haplotype phase. Background Currently, with Artesunate the availability of large-scale genotyping technologies, the genotyping cost of genome-wide association (GWA) studies has been largely reduced and a boom of large-scale GWA studies is underway. Nevertheless, the success of most association studies is based on the linkage disequilibrium (LD) between the functional mutations and markers in a local region of the genome. Varieties of statistical methods that rely on LD pattern have been developed to map functional variants (Spielman et al. 1993; Olson et al. 1994; Rannala and Reeve 2001; Ardlie et al. 2002). The most straightforward approach of LD-based ...
Mean age of patients was 78±6.7 years with a baseline VA of 51±17 ETDRS letter scores. Mean change in VA was +6.8±12.3, +5.1±13.4 and 3.3±14.9 letters at 3, 6 and 12 months, respectively. Patients received 4.2±1.1 and 6.4±2.3 injections in the first 6 and over 12 months, respectively. The AA genotype at rs11200638 (HTRA1 promoter SNP) predicted a better outcome of +7 and +9 letters after 6 (p= 0.003) and 12 months (p,0.0001), respectively. Similarly, the CC genotype at rs3793917 (LOC387715/ARMS2) was associated with increased VA outcome of +7 letters after 6 (p=0.006) and 12 months (p=0.001), whereas the TT genotype at rs10490924 (LOC387715/ARMS2) predicted a poorer VA response of -7 and -8 letters at 6 (p=0.004) and 12 months (p=0.001).. ...

6.Lab 6 - "If youve seen differences in the distribution of phenotypes in Tm4 over-expressing B35 cells versus control B35 cells, describe these differences. Formulate a hypothesis with regards to what changes on the molecular level may have occurred due to the over-expression of Tm4 that lead to morphological changes that you have observed" Genotype A corresponded to the tm4 over-expressing B35, while Genotype B corresponded to the wildtype control B35 cells. Between these two genotypes differences in their distribution of phenotypes was observed through total cell counts. In the control B35 cells, the majority of cells were of stumped or prolonged phenotypes, with all other phenotypes,(besides fan phenotype with nearly no cells), receiving an equal distribution of remaining cells. However, changes were seen when observing the phenotypes of the Tm4 over-expressing B35 cells, with the majority of cells falling into prolonged and stringed phenotype groups, followed by the stumped phenotype. The ...
As most commonly used within SNPedia, genotype refers to the pair of SNPs inherited at a given chromosomal position, one inherited from Dad, one inherited from Mom. Example: rs1234(A;C) is how we indicate someone with a (A;C) genotype at snp rs1234. However, this definition of genotype varies a bit from the one intended when it first introduced over 100 years ago [10.1126/science.35.896.340], and even from the most common usage in genetics textbooks. Although genotype can refer to an individuals genetic constitution (as a whole), the most typical usage is to refer to the pair of alleles carried by an individual at a given locus (or gene). Alleles are classically defined by their protein products and mode of inheritance (e.g. dominant, recessive, etc.), but at a molecular level, alleles may also be defined by one or more co-inherited SNPs. See also Magnitude and Repute Notable genotypes ...

The impact of the common alleles at structural loci coding for apolipoprotein (apos) A-IV, E, and H on 12 quantitative risk factors for cardiovascular disease (apos A-I, A-II, B, C-II, C-III, and E; total cholesterol; triglycerides; high density lipoprotein cholesterol; systolic blood pressure; diastolic blood pressure; and red blood cell sodium-lithium countertransport) was estimated in 453 unrelated individuals (227 men and 226 women) aged 26-63 years from the Rochester Family Heart Study, who were not using medications affecting lipid levels or blood pressure. Each risk factor was adjusted for concomitants (assay date, age, age, squared, height, weight and smoking status) before the genotypic effects on mean levels and variances were estimated. Allele frequencies were the same in men and women and were similar to those observed in other studies of US Caucasians. There were very different gender-specific estimates of the relative contribution of concomitants, measured genetic effects, and ...
Exploring the structure of genomes and analysing their evolution is essential to understand the ecological adaptation of organisms. However, with the large amounts of data being produced by Next Generation Sequencing (NGS), computational challenges arise in terms of storage, search, sharing, analysis, and visualisation. This is particularly true regarding genomic variation studies that are currently lacking scalable and user-friendly data exploration solutions. Here we present Gigwa, a web-based tool which provides an easy and intuitive way to explore large amounts of genotyping data by filtering the latter based not only on variant features, including functional annotations, but also on genotype patterns. The data storage relies on MongoDB, which offers good scalability perspectives. Gigwa can handle multiple databases and may be deployed in either single or multi-user mode. Finally, it provides a wide range of popular export formats. The Gigwa application is suitable to manage large amounts of

Although it has been well established that DNA repair plays critical roles in human carcinogenesis, limited data are available on the association between DNA repair and CaP risk. In this study, we provide direct evidence that an amino acid substitution variant in the ADPRT gene may contribute to decreased cellular repair function and be able to serve as a marker for CaP susceptibility. Intriguingly, both associations follow an allele dosage-dependent manner, the AA genotype is associated with a significantly higher CaP risk and lower enzyme activity, and the VA genotype carriers have a slight but not significantly increased CaP risk and decreased enzyme activity. Because this variant allele is relatively common in the general population (5-33%), our findings have biological and public health significance.. The genotype distribution of our Caucasian control population was comparable with that seen in a previous study of Caucasians (13) . In this study, the ADPRT 762 AA genotype was seen only in ...

Interleukin-12 (IL-12) as an antitumor and interleukin-6 (IL-6) as an inflammatory cytokine, are immunomodulatory products that play important roles in responses in cancers and inflammation. We tested the association between two polymorphisms of IL-12(1188A>C; rs3212227) and IL-6 (-174 C>G) and the risk of bladder cancer in 261 patients and 251 healthy individuals. We also investigated the possible association of these SNPs in patients with high-risk jobs and smoking habits with the incidence of bladder cancer. The genotype distributions of IL-6 (-174 C/G) genotype were similar between the cases and the control groups; however, among patients with smoking habits, the association between IL-6 gene polymorphism and incidence of bladder cancer was significant. After a control adjustment for age and sex, the following results were recorded: CC genotype (OR= 2.11, 95%CI=1.56-2.87, p=0.007), GC genotype (OR=2.18, 95%CI=1.16-4.12, p=0.014) and GC+ CC (OR=2.6, 95%CI=1.43-4.47, p=0.011).

q,/sup, mutation. I found various strains that are supposed to have this mutation: [[E. coli genotypes#D1210 , D1210]], [[E. coli genotypes#JM109 , JM109]], [[E. coli genotypes#BW26434, CGSC Strain # 7658 , BW26434]]. Then, since I was getting some anomalous experimental results, Tom suggested that I sequence verify the fact that my strains were lacI,sup,q,/sup,. So I did and lo and behold, none of my sequences had the lacI,sup,q,/sup, mutation on the genome. Now based on my anomalous experimental results (which are no longer so anomalous) and reading of some papers, I think that [[E. coli genotypes#D1210 , D1210]] really is lacI,sup,q,/sup, but that it just has lacI,sup,q,/sup, on the F plasmid rather than on the genome. But [[E. coli genotypes#JM109 , JM109]] and [[E. coli genotypes#BW26434, CGSC Strain # 7658 , BW26434]] ... or at least the versions that I sequenced ... are not lacI,sup,q,/sup, as documented.

After genotyping is done on your DNA sequence, what happens next? If the data tells us that you are genetically predisposed to certain diseases, that gives us two important pieces of information. First, you and your doctor will know about other symptoms that you should be vigilant in watching for. Second, it lets us know if there are any diet or lifestyle changes that you can make to prevent the onset of the disease.. Here is a specific example. If a woman has a family history of breast cancer, genotyping can let us know whether she has the BRCA 1 or BRCA 2 mutations. About one in five women with these mutations will never develop breast or ovarian cancer in her lifetime, but the other four will. Therefore, if the mutations are located, she will want to have regular mammograms to detect the cancer early.. ...

Increased knowledge of the gene-disease associations contributing to common cancer development raises the prospect of population stratification by genotype and other risk factors. Individual risk assessments could be used to target interventions such as screening, treatment and health education. Genotyping neonates, infants or young children as part of a systematic programme would improve coverage and uptake, and facilitate a screening package that maximises potential benefits and minimises harms including overdiagnosis. This paper explores the potential justifications and risks of genotyping children for genetic variants associated with common cancer development within a personalised screening programme. It identifies the ethical and legal principles that might guide population genotyping where the predictive value of the testing is modest and associated risks might arise in the future, and considers the standards required by population screening programme validity measures (such as the Wilson and

The main claimed benefits of internalism are that it results in a unique memetic substrate, something like a unique memetic code and it features a clean division between genotype and phenotype. However, internalism suffers from many problems. In particular computers do a lot of copying these days. Audio files spread contagiously through peer-to-peer networks today, but most of the information that is inherited when they are copied never gets into brains. Instead, brains receive a pale shadow of the information that is actually copied. The copying process is performed by machines, although it is usually still triggered by humans. Expanding internalism to include computers (as well as brains) would negate most of its claimed benefits. Internalism also features a curious stage in which genotypes are recreated from phenotypes - and it features ubiquitous Lamarckian inheritance - none of which looks very much like organic genetics. An externalist perspective arises naturally from an ...
difference between the regression coefficients of two sub samples. "The Chow test is used to examine the effect of structural change due to price or policy alteration on a regression model involving time series data" (Gujarati, 2003). If there are two sub-samples (say, based on two time periods) we find the Residual Sum of Squares for each sample. Let the Residual Sum of Squares of the first sample be RSS1, Residual Sum of Squares of the second sample be RSS2. Now let the Residual Sum of Squares be RSS. Then the F ratio is defined as ((RSS - RSS1 - RSS2 )/k) / ((RSS1+RSS2+…+RSSk)/(n1+n2-2k)) which follows F distribution with k, n1+n2 - 2k df... Chow test Chow test is used to find the significant ...

The present investigation was undertaken to study the genetic polymorphism of the DRB3 exon 2 in 75 crossbred cattle by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique. Five genotypes i.e. HaeIII-a, HaeIII-b, HaeIII-e, HaeIII-ab and HaeIII-ae were observed when the 284 bp PCR products were digested with HaeIII restriction enzyme. The corresponding frequencies of these patterns were 0.53, 0.04, 0.01, 0.38 and 0.04, respectively. Digestion with RsaI restriction enzyme resolved 24 different restriction patterns. The frequencies of these patterns ranged from 0.013 (RsaI-f, RsaI-k and RsaI-c/n) to 0.120 (RsaI-n). The results revealed that the crossbred cows belonged to the RsaI patterns namely b, k, l, a/l, d/s, l/n, l/o and m/n, whose corresponding frequencies were 0.027, 0.013, 0.040, 0.027, 0.040, 0.067, 0.027 and 0.067, respectively. Digestion of the 284 bp PCR product of DRB3.2 gene with PstI in the crossbred cattle did not reveal any restriction site. ...

To assess percentages of hepatitis C virus (HCV) genotypes in infected Lebanese patients referred to St. George Hospital, Beirut, Lebanon, 77 infected cases were studied. Of those, 27 were hemodialysis patients. Genotyping was performed by nested PCR of the HCV core-region with specific primers, followed by DNA enzyme-immunoassay using HCV type and subtype-specific probes. Single genotype infections were detected in 52 patients (67.5%). In these cases, types 1, 2, 3 and 4 were detected in 19.5%, 32.5%, 5.1% and 10.4% of the cases respectively. Twenty-five (32.5%) samples showed mixed genotype infections. Single genotype distribution was significantly different among dialysis and non-dialysis patients. In the dialysis group, genotype 2 was predominant (80%, p , 0.001). In single HCV genotype-infected patients, subtype 1b was frequently detected in nondialysis cases (34.4%) whereas this genotype was found in only 5% of dialysis cases. Genotypes 5 and 6 were not detected in any of the cases ...

A multilocational evaluation of 20 soybean genotypes was conducted in two distinct locations (Nsukka in Derived Savanna agro-ecology and Jalingo in northern Guinea Savanna) of Nigeria in 2015 and 2016 cropping seasons. The main objective of this study was to assess the genotype-by-environment interaction (G x E) for specific traits such as number of pods, pod weight, seed yield and yield stability. The results revealed highly significant differences among the genotypes and locations for all the traits except for seed yield. Genotype by environment interaction was not significant for all the traits except for days to 50% flowering indicating relative consistency in time of flowering among the genotypes across the locations and year. The genotype, Ashuku produced the highest yield in the two locations. However, the most stable genotypes across the locations were Dadinkowa and Vom while the ideal environments were Jalingo 2016 (ENV2) and Nsukka 2016 (ENV4) which produced 14.0 and 14.5 g, respectively.
Chickpea is the major pulse crop cultivated in Ethiopia. However, its production is constrained due to genotype instability and environmental variability.  This research was carried out to examine the magnitude of environmental effect on yield of chickpea genotypes and to investigate the stability and adaptability of genotypes under different agro-ecologies.  Twelve genotypes evaluated in randomized complete block design with three replications in three locations for two continuative years. Various stability indices used to assess stability and genotype by environment performances. Combined analysis of variance for yield and yield components revealed highly significant (P≤0.01) differences for genotypes, environments and their interaction. Growing years do not show difference. The significant interaction showed genotypes respond differently across environments.  At Guduru, Hareto and Gitilo, top performing genotype in grain yield were genotype 229961 (2.33ton/ha), genotype 225887 (3
Background: Interleukin (IL)-23 has an important role in tumor immune regulation. Objective: To investigate the possible association of interleukin-23 receptor (IL23R) gene variants rs1884444, rs10889677 and rs11209026 with development of acute lymphoblastic leukemia (ALL). Methods: The IL23R variants were studied in 164 ALL patients and compared to 175 healthy controls by polymerase chain reaction-restriction fragment length polymorphism. The relationship between these variants and clinical and laboratory features of the patients and response to therapy were evaluated. Results: No significant differences in genotype and allele frequencies existed between patients and controls. The rs1884444TG genotype was significantly lower in patients who relapsed (24.2%) compared to those without relapse (55.9%, p=0.006). Fewer patients who relapsed had evidence of the G allele (P=0.034). The TG genotype was associated with a longer complete remission at1804±116 days compared to other genotypes (|1217 days, p=0.028
To increase tolerance to abiotic stresses in breeding programmes, typically families and collections of genotypes are evaluated in series of trials (environments) representing different levels of stress. The statistical analysis of the data from such trials concentrates on modelling the phenotypic behaviour of the genotypes across the set of environments. This phenotypic behaviour can be modelled in the form of genotype-specific linear and non-linear response curves in relation to environmental characterizations. Non-parallelism of the response curves indicates genotype × environment interaction. Identification of the genetic basis of the parameters determining the response curves will help in the development of breeding programmes for improving abiotic stress tolerance and understanding genotype × environment interaction. In this paper we present two strategies for locating quantitative trait loci for response-curve parameters and estimation of their allele effects. The procedures are ...

AU - Park, Yongjung. AU - Kim, Hyonsuk. PY - 2017/7/1. Y1 - 2017/7/1. N2 - Hepatitis C virus (HCV) genotype is a predictive marker for treatment response. We sequentially evaluated the performances of two nucleic acid amplification tests (NAATs) and one serology assay for HCV genotype: Abbott RealTime genotype II (RealTime II), GeneMatrix restriction fragment mass polymorphism (RFMP), and Sysmex HISCL HCV Gr (HISCL Gr). We examined 281 clinical samples with three assays. The accuracy was assessed using the HCV Genotype Performance Panel PHW204 (SeraCare Life Sciences) for two NAATs. Discrepant cases were re-genotyped by the Versant HCV v.2.0 (line probe 2.0) assay. With the RealTime II assay, clinic samples were analyzed as follows: genotypes 1b (43.1%), 2 (40.2%), 1 subtypes other than 1a and 1b (12.5%), ...
1. Angiotensin-converting enzyme (ACE) genotypes in hypertensive patients were studied in order to delineate their cardiovascular risk due to the ACE gene. We hypothesized that the distribution of ACE genotypes may change with age because of the risk of myocardial infarction associated with the homozygous deletional (DD) genotype. 2. A total of 223 subjects were recruited from the Hypertension Outpatient Clinic of the Sai Ying Pun Hospital with consent. They consisted of 75 patients with newly diagnosed or documented hypertension, 46 patients with ischaemic heart disease and 102 normal controls. Genomic DNA was extracted from peripheral leucocytes and amplified by polymerase chain reaction. Insertion (I) or deletion (D) alleles were identified after electrophoresis. The frequencies of ACE genotypes and alleles were measured in three age groups: | 50 years, 50-59 years and | or = 60 years. 3. A significant correlation between ACE genotype and age was found (P = 0.03). The relative frequency of the D
Aim: The current study was conducted to investigate the effect of GSTP1 codon 105 polymorphism, alone and in combination with GSTM1-deletion polymorphism, on erythrocyte GST activity in 196 Han Chinese. Methods: GST activity was measured in healthy Chinese by a spectrophotometric method (n = 196; 101 males and 95 females; age range 21-81 years; median 43.5 years). GSTM1 polymorphisms were analyzed by a PCR-Multiplex procedure, whereas GSTP1 polymorphism was analyzed by PCR-RFLP. Results: The frequency of GSTM1 null genotype was 56.1% and the frequency of I/I, I/V, and V/V genotypes was 60.7%, 35.2% and 4.1%, respectively, in Han Chinese. The mean erythrocyte GST enzyme activity for I/V genotype group(3.53 ± 0.63 U · g-1 Hb) was significantly lower than that for I/I genotypes (4.25 ± 1.07 U · g-1 Hb, P = 0.000), while significantly higher than that for V/V genotypes (2.44 ± O. 67 U · g-1 Hb, P = 0.004). In GSTM1 (-) group, the GST activity of carriers of GSTM1 (-)/ GSTP1 - I/I is ...
INTRODUCTION: Asthma is a common respiratory childhood disease that results from an interaction between genetic, environmental and immunologic factors. The implication of nucleotide-binding and oligomerization domain 1 and 2 (NOD1/CARD4, NOD2/CARD15) was highlighted in many inflammatory diseases.. METHODS: In this case-control study, we analyzed the association of three NOD2 polymorphisms and one NOD1 variant, in 338 Tunisian asthmatic children and 425 healthy Controls, using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. We also assessed NOD1 and NOD2 mRNA and protein levels by qRT-PCR and ELISA techniques.. RESULTS: The homozygous AA genotype of rs2075820 was a risk factor for asthma (OR 2.39). The influence of the E266K variant in the presence of the heterozygous AG genotype was higher in male than female groups. The homozygous AA genotype was a risk factor associated with asthma, for patients aged between 6 and 18 years OR 2.39, IC95% (1.04-5.49) p , ...
Of all the lesions, HPV 16 was the most frequent genotype. This finding is in accordance with many other studies carried out worldwide [20]. In our study, this genotype was present in 35.3% of total lesions. However, in a previous study carried in our hospital from 1993 to 2000, the HPV 16 presence in the total number of lesions was somewhat higher than at present (39%) [21]. Also, in a recent study carried in a southern region of Spain from 2006 to 2007, this presence was even lower than ours (21.2%) [17].. As expected, HPV16 presence increased in accordance with the grade of the lesion (15.8% in benign lesions, 26.1% in CIN1 cases, 56.3% in CIN2-3 cases and 71.4% in ICC).. HPV 31 was the second most frequent genotype in CIN1 lesions and in CIN2-3 lesions. In a study carried in an eastern region of Spain, HPV 31 was also the second most frequent genotype in HSIL lesions and the presence found in these (10.8%) was very similar to the presence obtained in our study (10.8%) [19]. Previous ...
