Severe Combined Immunodeficiency (SCID Including Omenn Syndrome): RAG1 (Full Gene Sequencing)
Use
Confirm a clinical diagnosis of SCID; detect carriers; allow early diagnosis in family members
Special Instructions
Not provided.
Limitations
This test does not reliably detect mosaic variants, large deletions, duplications, inversions, other rearrangements, or deep intronic variants. There may be issues with allele-dropout, inability to determine exact numbers of T/A or microsatellite repeats, and no conclusion if two heterozygous variants are present on the same or different chromosome copies. This method was developed and its performance characteristics determined by Labcorp; it has not been cleared or approved by the FDA.
