Difference Between Genome and Exome

What is the difference between Exome Sequencing and Whole Genome Sequencing? Whole Genome Sequencing sequences the complete DNA of an organism. ... The exome makes up only 1.5% of the whole human genome, however ALL protein coding genes are found in the exome.

What is exome and genome sequencing?

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). ... The second step is to sequence the exonic DNA using any high-throughput DNA sequencing technology.

What does exome mean?

: the part of the genome consisting of exons that code information for protein synthesis The Personal Genome Project is beginning with the exome: the 1 percent of our genome that is translated into strings of amino acids that assemble themselves into proteins.—

What is exome sequencing used for?

What Is the Purpose of Whole Exome Sequencing? The purpose of whole exome sequencing is to try to find a genetic cause of your or your child's signs and symptoms. Most people who have WES have already had some genetic testing. WES is one of the most extensive genetic tests available.

How many genes does an exome have?

The exome of the human genome consists of roughly 180,000 exons constituting about 1% of the total genome, or about 30 megabases of DNA. Though composing a very small fraction of the genome, mutations in the exome are thought to harbor 85% of mutations that have a large effect on disease.

Can I get my whole genome sequenced?

Genomic Big Data Access

Whole Genome Sequencing DNA testing uses high throughput next-generation DNA sequencing technology. Because it is the most complete sequencing method, the full sequencing of a human genome at 30x coverage produces over 100 gigabytes of raw DNA data (over 300 gigabytes of data at 100x coverage).

What can Genome Sequencing tell us?

Whole genome sequencing is a lot like weather forecasting. It doesn't predict exactly what will happen, but gives you the chances of something happening. This means that it will tell you more about your risk for a certain disease, like diabetes, not if you have diabetes or not.

What is the human exome?

The “exome” consists of all the genome's exons, which are the coding portions of genes. ... The human genome consists of 3 billion nucleotides or “letters” of DNA. But only a small percentage — 1.5 percent — of those letters are actually translated into proteins, the functional players in the body.

How much does exome sequencing cost?

Whole exome sequencing costs range from $400 to $1,500, plus extra charges for analyzing the results. For insurance company Discovery, exome sequencing will be offered through a behavioral wellness program that provides clients with tools and incentives to make lifestyle changes to help them stay healthy.

What is a clinical exome?

Clinical Exome Sequencing is a test for identifying disease-causing DNA variants within the 1% of the genome which codes for proteins (exons) or flanks the regions which code for proteins (splice junctions). ... On average, 20,000 DNA variants are detected in exons per patient.

How accurate is whole exome sequencing?

“On average, we capture and sequence >99.4% of the exome with a quality enabling reliable variant calls. Coverage also refers to how many times each nucleotide is being sequenced.

What are the benefits of whole genome sequencing?

The primary purpose of sequencing one's genome is to obtain information of medical value for future care. Genomic sequencing can provide information on genetic variants that can lead to disease or can increase the risk of disease development, even in asymptomatic people.

Is Whole exome sequencing FDA approved?

Helix Laboratory Platform Granted the First and Only FDA Authorization for a Whole Exome Sequencing Platform. ... This marks the first time such a broad, sequencing-based device has been authorized by the FDA.
