Summary
Comprehensive genetic sequencing offers a path to personalized medicine by uncovering pharmacogenomic variations. This approach moves beyond single gene testing to fully understand drug responses and improve treatment outcomes.
Area of Science:
- Pharmacogenomics
- Genetics
- Drug Metabolism
Background:
- Genetic factors significantly influence individual drug efficacy and toxicity.
- Current understanding of genetic variations in drug disposition is incomplete, with candidate polymorphisms explaining only a fraction of variability.
- The concept of "missing heritability" highlights the need for broader genetic analyses.
Purpose of the Study:
- To provide an updated overview of pharmacogenomic variability using population-scale sequencing data.
- To summarize methods for estimating the functional consequences of variants with unknown effects in pharmacogenes.
- To discuss the importance of ethnogeographic diversity and implementation challenges for clinical decision-making.
Main Methods:
- Analysis of population-scale sequencing projects to map pharmacogenomic variations.
- Review of current methodologies for functional variant effect estimation.
- Discussion of challenges specific to pharmacogenes and clinical implementation.
Main Results:
- Advancements in genetic profiling enable comprehensive analysis of pharmacogenetic variations.
- New opportunities exist to identify novel factors contributing to drug response variability.
- Ethnogeographic diversity is crucial for equitable pharmacogenomic benefits.
Conclusions:
- Pharmacogenetic testing is transitioning from candidate polymorphism interrogation to comprehensive sequencing.
- Full spectrum pharmacogenomic variation analysis is essential for true personalized genomic prescribing.
- Addressing implementation roadblocks is key for clinical adoption.

The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.

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...

15.7K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

DNA sequencing is a fundamental technique that is routinely used in the biological sciences. This method can be applied to a range of questions at different scales - from the sequencing of a cloned DNA fragment or the study of a mutation in a gene up to whole-genome sequencing. However, despite the widespread use of sequencing today, it was not until 1977 that Fredrick Sanger and his collaborators developed the chain-termination method to decode DNA sequences. It relies on the separation of a...

11.4K
In the same year as the discovery of the Sanger sequencing method, another group of scientists, Allan Maxam and Walter Gilbert, demonstrated their chemical-cleavage method for DNA sequencing. The Maxam-Gilbert method relies on using different chemicals that can cleave the DNA sequence at specific sites, the separation of resulting DNA fragments of variable size using electrophoresis, and deciphering the DNA sequence from the resulting gel bands.
