Oncogenic: The passage mentions that the identified EGFR mutations contribute to tumor development in glioblastomas, particularly noting the presence of somatic mutations in the tumor samples. Predisposing: The passage specifies that one of the mutations (E330K) was identified as germline, indicating it confers inherited risk for developing disease.

      Evidence Type(s): Diagnostic, Predisposing

      Justification: Diagnostic: The passage discusses individuals with mosaic PIK3CA mutations, including the p.Glu726Lys variant, in the context of classic features of MCAP, indicating its role in defining or classifying the disease. Predisposing: The passage mentions that several patients with the p.Glu726Lys mutation had various clinical findings associated with MCAP, suggesting an inherited risk for developing this condition.

    1. Recurrent alteration of RIT1 alanine 77 was also observed; one of the ten mutated samples from this analysis harbored a p.A77P mutation and an additional TCGA sample (TCGA-73-4666) harbored a p.A77S mutation. TCGA-73-466

      Justification: Diagnostic: The passage discusses the recurrent alteration of RIT1 alanine 77 and mentions that one of the mutated samples harbored a p.A77P mutation, indicating its association with tumor classification. Predisposing: The passage suggests that p.A77S may represent a rare germline variant, indicating a potential inherited risk for disease, although it is noted to be unlikely.

      Evidence Type(s): Predisposing, Diagnostic, Functional

      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.
