Whole Exome Sequencing (WES) and Analysis
Whole Exome Sequencing (WES) is a powerful genetic test that analyzes the exome—the protein-coding regions of the genome. The exome constitutes approximately 1-2% of the entire genome but contains the majority of known disease-causing mutations. WES provides valuable insights into genetic variations that may contribute to inherited conditions, complex disorders, or unexplained symptoms.
What the Whole Exome Sequencing analyzes
WES identifies variations in the DNA sequence of exons, the regions that encode proteins. These regions are crucial because proteins perform most biological functions, and mutations in these areas often lead to genetic disorders.
How the Test Works
- Sample Collection: A blood or saliva sample is collected from the individual.
- DNA Extraction: DNA is extracted from the sample for sequencing.
- Sequencing: Advanced sequencing technologies analyze all exons in the genome, identifying genetic variants.
- Data Analysis: Bioinformatics tools interpret the data to pinpoint mutations linked to diseases or conditions.
Benefits of WES
- Comprehensive Diagnosis: Detects a wide range of genetic mutations, including rare or novel variants.
- Personalized Medicine: Guides treatment strategies based on the individual’s genetic makeup.
- Family Planning: Helps identify carrier status for hereditary conditions.
- Unexplained Symptoms: Offers insights into undiagnosed or complex medical cases.
Applications
WES is particularly useful for:
- Diagnosing rare genetic disorders.
- Identifying genetic risk factors for inherited conditions.
- Exploring causes of developmental delays, intellectual disabilities, or autism spectrum disorders.
While WES is a powerful diagnostic tool, healthcare professionals should interpret its results alongside clinical findings. It represents a significant step toward precision medicine, offering personalized insights into health and disease.
