Clinical Exome Sequencing (DNA Extraction)

Clinical Exome Sequencing (DNA Extraction)

Overview
Clinical Exome Sequencing (CES) is an advanced genetic test that analyzes the protein-coding regions (exons) of genes associated with inherited disorders. DNA extraction is the crucial first step in this process, where high-quality DNA is isolated from the patient's sample for sequencing and analysis.

Why is this test done?

• Investigate suspected genetic disorders.
• Identify disease-causing genetic variants.
• Support diagnosis of rare and inherited conditions.
• Assist in treatment planning and genetic counseling.
• Evaluate unexplained developmental, neurological, or metabolic disorders.

Sample Required

• Whole Blood (EDTA)

Preparation

• No special preparation or fasting is required.

Benefits

• Provides the foundation for accurate genetic sequencing.
• Enables comprehensive analysis of thousands of clinically relevant genes.
• Helps clinicians reach a precise diagnosis for complex conditions.

Who should consider this test?

• Individuals with symptoms suggestive of a genetic disorder.
• Children with developmental delays or congenital anomalies.
• Patients with unexplained medical conditions where a genetic cause is suspected.
• Families seeking genetic risk assessment.

Note: DNA extraction is the preparatory laboratory step and does not provide diagnostic results by itself. The final interpretation is available after Clinical Exome Sequencing and genetic analysis are completed.
