Mosaic Overgrowth with Fibroadipose Hyperplasia is Caused by Somatic Activating Mutations in PIK3CA
[Paper-level Aggregated] PMCID: PMC3461408
Evidence Type(s): Oncogenic, Functional
Justification: Oncogenic: The text identifies the cancer-associated mutations p.His1047Leu and p.His1047Arg in PIK3CA, which are linked to a syndrome characterized by overgrowth, indicating their role in tumorigenesis. Functional: The evidence shows that affected dermal fibroblasts exhibit enhanced phosphatidylinositol-3,4,5-trisphosphate generation and activation of downstream signaling, demonstrating the functional impact of the mutations on PI3K signaling.
