WES Whole Exome Sequencing

Complete DNA test to identify mutations in over 24,000 genes related to complex genetic problems

What is WES test?

Most of disease-causing mutations occur in the exome. Exome has 1.7 percent of a human genome that encodes proteins. Thus, Whole Exome Sequencing (WES) is:

Highly extensive to identify genetic mutations or alterations in DNA that may not have been picked in earlier genetic tests.
Couples can plan their family through this genetic diagnosis and eliminate their chances of having an affected child. This information can be useful for other members in the same family as well.
Advanced NGS (Next Generation Sequencing) technology is used to determine the information obtained from millions of DNA fragments.
Performed +14.000 clinical exomes since 2015
Managing more than 650 tests per month and more than 350 exomes particularly in UAE
Large experience in wet lab and bioinformatics with Arabic database definition
More than 20 years of experience
CAP Accredited

What is the procedure?

Report will be delivered in 8-9 weeks after receiving the samples in our lab

Why use WES test?

An exome sequencing study can identify:

Numerous mutations or changes in the DNA that can result in an affected child in the patient’s family.
The main indication of exome sequencing is to characterize an unmapped monogenic genetic disease present in a descendant, recognized as an index patient.
The WES test aims to identify a mutation that explains the symptoms associated with a typically hereditary disease.
Most advanced methodology, NGS is used to obtain the information from millions of DNA fragments corresponding to over 24.000 genes that consists of a set of molecular biology and bioinformatics analysis tools.
An additional 6 genes such as Congenital Adrenal Hyperplasia (CAH), Fragile X, Spinal Muscular Atrophy (SMA), Hemophilia A, Duchenne Muscular Dystrophy (DMD), Spinocerebellar Ataxia (types to be determined) are done on Sanger Sequencing to assure the accuracy and consistency of the WES.

Who should use WES test?

Couples who plan on forming a family and want to know the risk of transmitting hereditary disorders to their children
Patients planning an assisted reproduction treatment
Patients planning a treatment with donor sperm or eggs

Most carriers of genetic mutations don’t have a family history of these disorders.

Results

This technique allows the detection of aneuploidy only for the chromosomes included in the test (13, 18, 21, X and Y). In very few ejaculated samples or testicular samples, there is not enough spermatozoa for a proper estimation of the risk of aneuploidy.

Positive

The tested person carries a mutation in a particular gene. The test should be carried out in the other member of the couple
Negative

A negative result indicates that the person doesn’t carry any of the mutations studied.
There is still a small risk of carrying another mutation not analyzed by the test.
