Diagnostic, Oncogenic evidence:
Diagnostic: The study discusses how patients with VHL disease inherit a mutation in one VHL allele, which allows for the examination of heterozygous VHL expression in neutrophils. This indicates that the variant is used to define and study the effects of VHL mutations in the context of a specific disease, thus supporting its classification as diagnostic.
Oncogenic: The mention of heterozygous VHL defects perturbing normal responses suggests that the variant contributes to tumor development or progression, particularly in the context of VHL disease. This aligns with the oncogenic classification as it implies a role in cancer biology.
