Hyper-IgM Syndrome (HIGM): (CD40 [TNFRSF5] for HIGM3) (Full Gene Sequencing)
Use
Confirm a clinical diagnosis of HIGM; detect carriers; allow early diagnosis in family members, guiding prophylactic measures
Special Instructions
Not provided.
Limitations
This method does not reliably detect mosaic variants; large deletions; large duplications, inversions or other rearrangements; or deep intronic variants. It may be affected by allele-dropout, it may not allow determination of the exact numbers of T/A or microsatellite repeats, and it does not allow any conclusion as to whether two heterozygous variants are present on the same or on different chromosome copies. This test was developed and its performance characteristics determined by Labcorp. It has not been cleared or approved by the Food and Drug Administration.
