Severe Combined Immunodeficiency (SCID): CD3E (Full Gene Sequencing)
Use
Confirm a clinical diagnosis of SCID; detect carriers; allow early diagnosis in family members
Special Instructions
Test orders must include an attestation that the provider has the patient's informed consent for genetic testing. In the case of family tests (e.g., known mutations), submit the result report of the index case if available. For more information, see the Informed Consent for Genetic Testing in the Related Documents section.
Limitations
This method does not reliably detect mosaic variants, large deletions, duplications, inversions, or other structural rearrangements. It is also not effective for detecting deep intronic variants, allele dropout, or determining T/A or microsatellite repeat numbers. It may not indicate whether two heterozygous variants occur on the same or different chromosome copies.
