Evidence Type(s): Oncogenic, Prognostic

Justification: Oncogenic: The presence of PIK3CA mutations, specifically H1047R and E542K, is associated with tumorigenesis, as indicated by their occurrence in tumor samples and the context of their mutation hotspots. Prognostic: The study suggests a correlation between PIK3CA mutations and PTEN expression loss, which may have implications for patient outcomes, particularly since a significant portion of patients with the H1047R mutation also exhibited PTEN loss.

[Paragraph-level] PMCID: PMC3141770 Section: RESULTS PassageIndex: 6

Evidence Type(s): Oncogenic

Justification: Oncogenic: The passage indicates that the H1047R mutation is associated with PTEN loss in patients, suggesting that it contributes to tumor development or progression.

Gene→Variant (gene-first): 5290:H1047R

Genes: 5290

Variants: H1047R

[Paragraph-level] PMCID: PMC3141770 Section: RESULTS PassageIndex: 5

Evidence Type(s): Diagnostic, Oncogenic

Justification: Diagnostic: The passage discusses the incidence of PIK3CA mutations and their occurrence in specific samples, indicating their association with the disease. Oncogenic: The mention of PIK3CA mutations, including E542K and H1047R, suggests their role in tumor development, as they are described as mutations found in tumor samples.
