Pharmacogenomics: Identification of New Drug Targets

86
Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...

Genome-wide Association Studies-GWAS

16.7K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Genetic Screens02:46

Genetic Screens

5.9K
Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing  genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which...

Genomics

41.8K
Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

Principles of Pharmacogenetics: Types of Genetic Variants

102
The human genome is over 99.9% identical between individuals, yet genetic differences exist at millions of bases. The human genome contains approximately 3 million variant positions per individual, many of which are heterozygous, contributing to genetic diversity and individual traits. Genetic variations include single-nucleotide polymorphisms (SNPs), insertions, deletions, and copy number variations (CNVs).SNPs, the most common variation, involve single-base changes in DNA. These can be...

Pharmacogenetics and Pharmacogenomics: Overview01:29

Pharmacogenetics and Pharmacogenomics: Overview

158
Pharmacogenetics and pharmacogenomics examine how genetic factors influence an individual's response to drugs. While pharmacogenetics focuses on the impact of specific genetic variants on drug effects, pharmacogenomics takes a broader approach, studying how genetic variation across populations contributes to differences in drug responses. These fields aim to explain why individuals may experience varying levels of efficacy or adverse reactions to the same medication.Variability in drug...

Area of Science:

  • Genomics
  • Bioinformatics
  • Computational Biology

Background:

  • Next-generation sequencing generates vast amounts of data, necessitating efficient analytical methods.
  • Identifying disease-associated genes from large genomic datasets is a significant challenge.

Purpose of the Study:

  • To introduce GeneCOST, a novel scoring-based method for evaluating gene-disease associations.
  • To develop a framework for prioritizing genes based on their likelihood of causing disease, without requiring prior filtering or knowledge.

Main Methods:

  • GeneCOST assigns a disease likelihood score to each gene based on its variations.
  • Genes are ranked using frequency, conservation, pedigree, and detailed variation information.
  • The method was tested on Mendelian disease cases, including recessive, dominant, compound heterozygous, and sporadic models.

Main Results:

  • GeneCOST successfully identified causative genes within the top rankings for various Mendelian disease models.
  • The method demonstrated effectiveness in pinpointing the genetic basis of disease states.
  • The study validates GeneCOST as a powerful alternative to traditional filtering-based approaches in genetic disease analysis.

Conclusions:

  • GeneCOST provides a robust prioritization framework for genetic disease studies.
  • The method facilitates the extraction of valuable information from big data generated by next-generation sequencing.
  • GeneCOST offers a novel approach to understanding the genetic underpinnings of diseases.
