Resistance to paclitaxel is associated with a variant of the gene BCL2 in multiple tumor types
[Paper-level Aggregated] PMCID: PMC6478919
Evidence Type(s): Predictive, Functional, Prognostic
Justification: Predictive: The variation at position 21 of the BCL2 sequence (+21 T > C) predicts response to paclitaxel treatment, as patients with the T variant showed resistance while those with the C variant were more likely to respond. Functional: The T > C variant at location 21 of BCL2 alters RNA secondary structure and increases transcript stability, leading to higher BCL2 protein levels, which is functionally relevant in the context of treatment response. Prognostic: The presence of the T variant at location 21 is associated with a poorer treatment outcome, as indicated by the higher percentage of patients with this variant who required multiple lines of therapy compared to those with the C variant.
