Thirty-five nucleotide polymorphisms were found in a 21.5-kbp region including the Est6 locus among 42 isoallelic lines extracted from a single natural population of Drosophila melanogaster. The heterozygosity per nucleotide pair was estimated to be 0.010 overall, but was lower in sequences hybridizing to transcripts than in those not hybridizing to transcripts. Eleven of 36 pairwise comparison...

Methods: A cohort of 48 patients with MFC was compared with previously characterized cohorts of patients with advanced AMD (368 samples) and matched unaffected controls (368 samples). Allele and genotype frequencies of single nucleotide polymorphisms for the following AMD-associated alleles were evaluated: risk alleles in complement factor H (CFH) gene (Y402H and IVS14) and LOC387715/HTRA1 gene...

In this study, we analyze the Genetic Analysis Workshop 18 data to identify the genes and underlying single-nucleotide polymorphisms on 11 chromosomes that exhibit significant association with systolic blood pressure. We propose a novel family-based method for rare-variant association detection based on the hierarchical Bayesian framework. The method controls spurious associations caused by pop...

Genome-wide association studies are largely based on single-nucleotide polymorphisms and rest on the common disease/common variants (single-nucleotide polymorphisms) hypothesis. However, it has been argued in the last few years and is well accepted now that rare variants are valuable for studying common diseases. Although current genome-wide association studies have successfully discovered many...

Bayesian approaches applied in association studies select regions of single-nucleotide polymorphisms, indicating genes with important effects. The methods differ terms the distribution assumed for marker Here, we used window posterior probability to detect potential regions. present study evaluated efficiency these identifying located close genes. Data were simulated six scenarios. Considering ...

Genetic Analysis Workshop 18 provided a platform for evaluating genomic prediction power based on single-nucleotide polymorphisms from single-nucleotide polymorphism array data and sequencing data. Also, Genetic Analysis Workshop 18 provided a diverse pedigree structure to be explored in prediction. In this study, we attempted to combine pedigree information with single-nucleotide polymorphism ...

MicroRNAs are small non coding RNAs that are involved in gene expression regulation. Mir-122 was reported to inhibit hepatitis B virus (HBV), but little is known about the role of mir-122 polymorphisms on HBV infection development. This present study aimed to investigate the association between single nucleotide polymorphisms (SNPs) in mir-122 gene region with HBV infection. Study cases were HB...

Single nucleotide polymorphisms (SNPs) are an abundant source of genetic variation among individual organisms. To assess the usefulness of SNPs for genome analysis in the yellow fever mosquito, Aedes aegypti, we sequenced 25 nuclear genes in each of three strains and analysed nucleotide diversity. The average frequency of nucleotide variation was 12 SNPs per kilobase, indicating that nucleotide...

single-nucleotide polymorphisms (snps) in mirnasmay alter its expression levels or processing and contribute to susceptibility to a wide range of diseases. our study aimed to evaluate the possible association between mirna-146a rs2910164 and mirna-499 rs3746444 polymorphisms and susceptibility to pulmonary tuberculosis (ptb) in a sample of iranian population. this case- control study was perfor...
