Clinical Delineation and Natural History of the PIK3CA-Related Overgrowth Spectrum
[Paper-level Aggregated] PMCID: PMC4320693
Evidence Type(s): Oncogenic, Prognostic
Justification: Oncogenic: The passage indicates that specific mutations, particularly p.His1047Arg and p.His1047Leu, are associated with distinct phenotypes in a significant proportion of patients, suggesting their role in tumorigenesis. Prognostic: The correlation of specific mutations with phenotypes such as FAO, HHML, and CLOVES syndrome implies that these mutations may provide prognostic information regarding disease manifestation and patient outcomes.
