      Evidence Type(s): Oncogenic, Functional, Predictive, Predisposing

      Justification: Oncogenic: The text mentions that certain PTEN variants, including C124S and G129E, have been found in somatic cancer, indicating their potential role in cancer development. Functional: The study assesses the functionality of various PTEN variants through multiple assays, demonstrating that many variants exhibit loss of function (LoF) or gain of function (GoF) phenotypes, impacting cellular processes such as synaptogenesis and insulin signaling. Predictive: The classification of variants as Pathogenic or Likely Pathogenic based on their functional impact suggests that these variants can predict disease outcomes, particularly in relation to ASD and other disorders. Predisposing: The identification of variants associated with ASD, intellectual disability, and developmental delay indicates that these genetic alterations may predispose individuals to these conditions.
