While for the METABRIC and SCAN-B, high BIRC5/survivin mRNA levels were significantly associated with worse survival in the N+ and in N− subgroups (N−, HR 1.45 [1.09–1.93], p 0.0104; N+, HR 1.84 [1.35–2.50]; p < 0.0001 for SCAN-B. The gene discussed is BIRC5; the disease is spinocerebellar ataxia, autosomal recessive, with axonal neuropathy.
