Wiskott-Aldrich Syndrome (WAS): WAS (Full Gene Sequencing)
Use
Confirm a clinical diagnosis of WAS; detect carriers; allow early diagnosis in family members
Special Instructions
If a known mutation is documented, the test 252690 may be preferred by the physician. Providers must include attestation of informed consent for genetic testing when ordering this test. For family tests involving known mutations, submit the index case result if not previously tested by LabCorp.
Limitations
The method does not reliably detect mosaic variants, large deletions, large duplications, inversions, rearrangements, or deep intronic variants. Challenges include allele dropout, inaccurately determining T/A or microsatellite repeats, and the inability to conclude if two heterozygous variants are on the same or different chromosome copies.
