Clinical sensitivity: Because the conditions targeted here are mostly ultra-rare, potentially under-diagnosed, and in need of more research, the clinical sensitivity is unknown. Mutations in the genes covered in our panel may account for 90% of the cases of primary/familial HLH; the cause of the remaining 10% is unknown. Nevertheless, … View more

Assay limitations: Help
This test will not detect variants located outside of the targeted DNA regions. This test is not optimized to detect chimerism or somatic mosaicism. This test will detect small indels but may miss larger deletions or duplications. Balanced structural variants will not be detected unless specifically targeted by a custom … View more
