AimsStudies implicated a role for a genetic variant in CEP72 in vincristine‐induced peripheral neuropathy. This study aims to evaluate this association in a cohort of brain tumour patients, to perform a cross‐disease meta‐analysis and explore the protein‐coding region of CEP72.MethodsIn total, 104 vincristine‐treated brain tumour patients were genotyped for CEP72 rs924607, and sequenced for the protein‐coding region. Data regarding patient and treatment characteristics, and peripheral neuropathy, were collected. Logistic regression and meta‐analysis were performed for rs924607 replication. A weighted burden analysis was applied to evaluate impact of overall genetic variation in CEP72.ResultsAnalysis of 24 cases and 80 controls did not show a significant association between CEP72 rs924607 and neuropathy (odds ratio, OR [95% confidence interval, CI] 2.076 [0.359–11.989], P = .414). When combined with 8 cohorts (1095 cancer patients), a significant increase in risk for neuropathy was found for patients with a TT genotype (OR [95% CI] 2.15 [1.35–3.43], P = .001). Additionally, a missense variant (rs12522955) was significantly associated (OR [95% CI] 2.3 [1.2–4.4], P = .041) and patients with severe neuropathy carried more impactful variants in CEP72 coding regions (P = .039).ConclusionThe association of CEP72 rs924607 in vincristine‐induced neuropathy was not confirmed in a cohort of brain tumour patients, but did contribute to its suggested effect when combined in a cross‐disease meta‐analysis. The importance of other genetic variations in CEP72 on vincristine‐induced neuropathy was demonstrated. This study contributes to evidence of the importance of genetic variants in CEP72 in development of vincristine‐induced toxicity, and provides guidance for future prospective studies.
