Evidence Type(s): Diagnostic, Oncogenic
Justification: Diagnostic: The passage discusses the identification of the c.241 G>A [p.E81K] mutation in a specific patient, indicating its association with the patient's condition and its absence in the patient's parents, which suggests its role in defining or confirming a disease. Oncogenic: The mention of the mutation being detected in various tissues of the patient, particularly in the context of a mutational analysis, implies its potential contribution to tumor development or progression.
