The cost of sequencing a human genome is dropping rapidly, due to the continual development of new, faster, cheaper DNA sequencing technologies such as "next-generation DNA sequencing". The National Human Genome Research Institute, an arm of the U.S. National Institutes of Health, has reported that the cost to sequence a whole human-sized ...
In recent years the development of high-throughput or next-generation sequencing has dramatically lowered the cost of DNA sequencing permitting laboratories to evaluate all 20,000 genes of the human genome at once through exome sequencing and whole genome sequencing. [9]
Exome sequencing, also known as whole exome sequencing (WES), is a genomic technique for sequencing all of the protein-coding regions of genes in a genome (known as the exome). [1] It consists of two steps: the first step is to select only the subset of DNA that encodes proteins .
The costs of genetic testing vary depending on the type and complexity of the test. According to health experts, genetic test costs range from $100 to more than $2,000 without coverage.
The term was coined by The Economist [3] and is named after author Rob Carlson. [1]Carlson curves illustrate the rapid (in some cases above exponential growth) decreases in cost, and increases in performance, of a variety of technologies, including DNA sequencing, DNA synthesis and a range of physical and computational tools used in protein production and in determining protein structures.
Rothberg estimated the cost of the sequence—the first personal genome produced using a next-generation sequencing platform—at $1 million. [12] Watson's genome sequence was published in 2008. [13] A number of scientists have highlighted the cost of additional analysis after performing sequencing.
