Evidence Type(s): Functional, Oncogenic
Justification: Functional: The passage discusses the evaluation of mRNA and protein expression levels of the R248H variant, indicating that it alters protein expression compared to oncogenic variants, which relates to its molecular function. Oncogenic: The passage implies that the R248H variant is classified as a non-oncogenic variant, contrasting it with oncogenic variants, suggesting its role in tumor development or progression is not supported.
