Evidence Type(s): Oncogenic

Summary: Mutation: p.His1047Leu | Summary: The p.His1047Leu mutation in PIK3CA is identified as a cancer-associated mutation contributing to tumor development in a patient with a syndrome of congenital overgrowth.

Evidence Type: Oncogenic Mutation: p.His1047Arg | Summary: The p.His1047Arg mutation in PIK3CA is identified as a cancer-associated mutation found in multiple patients with overlapping syndromes, indicating its role in tumor progression.

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.

Evidence Type(s): Oncogenic, Functional

Justification: Oncogenic: The passage discusses the identification of cancer-associated mutations p.His1047Leu and p.His1047Arg in PIK3CA, which are linked to a syndrome characterized by overgrowth, indicating that these somatic variants contribute to tumor development or progression. Functional: The passage describes how affected dermal fibroblasts showed enhanced phosphatidylinositol-3,4,5-trisphosphate (PIP3) generation and activation of downstream signaling, demonstrating that the variants alter molecular or biochemical function.
