Seven in absentia homolog 1 (SIAH-1) is a member of the RING-finger-containing E3 ubiquitin ligases. Two substrates of SIAH-1 are α-synuclein and synphilin-1, both of these proteins are involved in Parkinson's disease (PD). Recently, mutations in Parkin, another E3 ubiquitin ligase which ubiquinates synphilin-1 and glycosylated α-synuclein, have been defined as a major cause of autosomal recessive PD. The potential role of SIAH-1 in PD is further underlined as SIAH-1 protein is a component of the Lewy bodies and as it plays a role in apoptosis caused by nitric oxide (NO) induced oxidative stress. Thus, we performed a mutation screening of the SIAH-1 gene in PD patients. However, screening a large sample of 209 familial and sporadic PD patients we could not find any disease causing mutation. We therefore conclude that genetic alterations of SIAH-1 do not significantly contribute to the pathogenesis of PD.
