Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
DYT1 dystonia is an autosomal-dominantly inherited movement disorder, which is usually caused by a GAG deletion in the TOR1A gene. Due to the reduced penetrance of ~30-40%, the determination of the mutation in a subject is of limited use with regard to actual manifestation of symptoms. In the present study, we used Affymetrix oligonucleotide microarrays to analyze global gene expression in blood samples of 15 manifesting and 15 non-manifesting mutation carriers in order to identify a susceptibility profile beyond the GAG deletion which is associated with the manifestation of symptoms in DYT1 dystonia.We identified a genetic signature which distinguished between asymptomatic mutation carriers and symptomatic DYT1 patients with 86.7% sensitivity and 100% specificity. This genetic signature could correctly predict the disease state in an independent test set with a sensitivity of 87.5% and a specificity of 85.7%.Conclusively, this genetic signature might provide a possibility to distinguish DYT1 patients from asymptomatic mutation carriers.

Description
Primary pneumocytes from KRas;Atg5fl/+ and KRas;Atg5fl/fl littermates were cultured for 48 hours and infected with AdCre-GFP to induce expression of the KrasG12D oncogene and concomitant Atg5 deletion. The transcriptional profile of those cells was determined by mRNA sequencing and uncovered differential expression in cellular movement, inflammatory response and oxidative stress response. Overall design: Comparison of transcriptomes from KRas;Atg5fl/+ and KRas;Atg5fl/fl pneumocytes
