Recommended fields not provided:
Clinical validity, Clinical utility, Target population, What is the protocol for interpreting a variation as a VUS?, Are family members with defined clinical status recruited to assess significance of VUS without charge?, Will the lab re-contact the ordering physician if variant interpretation changes?, Is research allowed on the sample after clinical testing is complete?, Sample negative report, Sample positive report
Technical Information
Test Comments: Help
CD40 ligand by flow cytometry is also available through our Diagnostic Immunology Laboratory
Availability: Help
Tests performed
Entire test performed in-house
Analytical Validity: Help
Sequencing detects about 98% of mutations in CD40LG in males.
Assay limitations: Help
In females, test sensitivity is somewhat lower as PCR-based sequencing does not detect large deletions, insertions or rearrangements within a gene.
Proficiency testing (PT):
Is proficiency testing performed for this test? Help
Yes

Method used for proficiency testing: Help
Inter-Laboratory
