Recent studies have uncovered a strong effect of host genetic variation on the composition of host-associated microbiota. Here, we present HOMINID, a computational approach based on Lasso linear regression, that given host genetic variation and microbiome taxonomic composition data, identifies host single nucleotide polymorphisms (SNPs) that are correlated with microbial taxa abundances. Using ...
Rice is a facultative short-day plant, and molecular genetic studies have identified the major genes involved in short-day flowering. However, the molecular mechanisms promoting the diversity of flowering time in cultivated rice are not known. We used a core collection of 64 rice cultivars that represent the genetic diversity of 332 accessions from around the world and studied the expression le...
Forensic genetics, leveraging molecular tools and scientific applications, has witnessed significant advancements in DNA analysis over the last three decades. These progressions have enhanced discrimination power, speed, sensitivity of profiling methods, enabling challenging samples. This article explores significance forensic genetics criminal investigations, traces historical evolution techni...
results we identified no mutations in these patients in the three screened positions. conclusions to ensure that these genes play no role in the disease, evaluation of the non-coding regions of both the cyp1b1 and myoc genes is strongly recommended, since other genes are involved in the pathogenesis of glaucoma. patients and methods forty patients with poag were recruited from the ophthalmic di...
Structural genetic variation, including copy-number variation (CNV), constitutes a substantial fraction of total genetic variability and the importance of structural genetic variants in modulating human disease is increasingly being recognized. Early successes in identifying disease-associated CNVs via a candidate gene approach mandate that future disease association studies need to include str...
Single-nucleotide polymorphisms (SNPs) are the most frequent type of variation in the human genome, and they provide powerful tools for a variety of medical genetic studies. In a large-scale survey for SNPs, 2.3 megabases of human genomic DNA was examined by a combination of gel-based sequencing and high-density variation-detection DNA chips. A total of 3241 candidate SNPs were identified. A ge...
Genetic variation arising from single nucleotide polymorphisms (SNPs) is ubiquitously found among human populations. While disease-causing variants are known in some cases, identifying functional or causative variants for most human diseases remains a challenging task. Rare SNPs, rather than common ones, are thought to be more important in the pathology of most human diseases. We propose that r...
background: polymorphisms in the immune related genes are important in the clinical outcome of helicobacter pylori infection. myeloperoxidase -463 g/a polymorphism has been shown to reduce enzyme expression and activity. objective: the aim of the present study is to investigate the association of myeloperoxidase g-463a polymor-phism with clinical outcome of helicobacter pylori infection. method...
