What This Test Measures

This test detects mutations in a particular region (intron 122) of a gene that may be associated with inherited disorders. The test focuses on DNA extracted from your blood cells, which contains your genetic material.

Why It Might Be Ordered

Your healthcare provider may recommend this test if you or a family member have symptoms or a history of conditions linked to genetic mutations in this region, or if you’re at higher risk due to family history.

Sample Collection and Preparation

A blood sample is drawn from your arm, similar to other blood tests. The blood is processed to isolate DNA, which is then examined for the specific genetic changes of interest.

Results and Interpretation

Results are reported as either a positive (mutation detected) or negative (mutation not found). Interpretation requires input from a genetic counselor or healthcare provider to understand implications for your health.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Clinical Significance

Short name

INTRON122 Mutation Test (Whole Blood)
