Genome-Wide Study of Response to Platinum, Taxane, and Combination Therapy in Ovarian Cancer: In vitro Phenotypes, Inherited Variation, and Disease Recurrence.
In contrast to prior studies the frequency of the R621C substitution was not significantly different between PD and control subjects, neither were the V44A or E706Q substitutions.
Recently, the first genetic evidence for the direct contribution of synphilin-1 in the pathogenesis of PD has been defined with the identification of an R621C mutation as a susceptibility factor for PD in two German patients.
Our findings argue in favour of a causative role of the R621C mutation in the synphilin-1 gene in PD and suggest that the formation of intracellular inclusions may be beneficial to cells and that a mutation in synphilin-1 that reduces this ability may sensitize neurons to cellular stress.
To investigate an involvement of genetic variations of synphilin-1 in development of sporadic PD, a possible single nucleotide polymorphism (SNP) of T131C corresponding to a valine (Val) to alanine (Ala) substitution at codon 44 in exon 3 of the synphilin-1 gene was studied in a Japanese population of 55 patients with sporadic PD and 61 patients with non-PD by direct sequencing analysis.
The familial Parkinson's disease associated mutations of alpha-synuclein (Ala53Thr and Ala30Pro) also demonstrate a strong interaction between their C-terminal regions and synphilin-1.
