      Evidence Type(s): Predisposing, Oncogenic, Functional

      Justification: Predisposing: The passage describes germline substitutions in the TIE2/TEK receptor that cause a rare inherited form of venous anomalies, indicating that these variants confer inherited risk for developing the disease. Oncogenic: The passage discusses somatic mutations in TIE2 that contribute to tumor development, specifically noting the identification of somatic mutations in lesions and their role in the etiology of sporadic venous malformations. Functional: The passage mentions that the L914F variant shows ligand-independent hyperphosphorylation and abnormal localization when overexpressed, indicating that it alters molecular function.

      Justification: Predisposing: The passage describes the discovery of the GATA2 gene as a predisposition gene for myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML), indicating that the variants are associated with inherited risk for developing these diseases. Diagnostic: The variants are used to define and classify familial forms of MDS and AML, as they are reported to segregate with the disease in multiple families, which supports their role in diagnosis. Functional: The passage mentions that the mutations have differential effects on transactivation of target genes, cellular differentiation, apoptosis, and global gene expression, indicating that they alter molecular or biochemical function.
