Analytical Validity: Help
Approximately 70% of individuals with familial hemophagocytic lymphohistiocytosis (FHL) have pathogenic variants in PRF1, UNC13D, STX11 or STXBP2. About 2-3% of individuals with FHL have pathogenic variants in RAB27A. Other genes on this panel are associated with differential diagnoses for FHL, and the clinical sensitivity for these genes depend on … View more
Assay limitations: Help
Variants in the regulatory regions and nonreported variants in the untranslated regions may not be detected by this test. Large deletions/ duplications, large insertions and other complex genetic events will not be identified using sequencing methodology.
