- Background: There is tremendous potential for genome sequencing to improve clinical diagnosis and care once it becomes routinely accessible, but this will require formalizing research methods into clinical best practices in the areas of sequence data generation, analysis, interpretation and reporting. The CLARITY Challenge was designed to spur convergence in methods for diagnosing genetic disease starting from clinical case history and genome sequencing data. DNA samples were obtained from three families with heritable genetic disorders and genomic sequence data were donated by sequencing platform vendors. The challenge was to analyze and interpret these data with the goals of identifying disease-causing variants and reporting the findings in a clinically useful format. Participating contestant groups were solicited broadly, and an independent panel of judges evaluated their performance. Results: A total of 30 international groups were engaged. The entries reveal a general convergence of practices on most elements of the analysis and interpretation process. However, even given this commonality of approach, only two groups identified the consensus candidate variants in all disease cases, demonstrating a need for consistent fine-tuning of the generally accepted methods. There was greater diversity of the final clinical report content and in the patient consenting process, demonstrating that these areas require additional exploration and standardization. Conclusions: The CLARITY Challenge provides a comprehensive assessment of current practices for using genome sequencing to diagnose and report genetic diseases. There is remarkable convergence in bioinformatic techniques, but medical interpretation and reporting are areas that require further development by many groups.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Health economic studies in Parkinson's disease (PD) have become increasingly common in recent years. Because several methodologies and instruments have been used to assess cost and outcomes in PD, the Movement Disorder Society (MDS) commissioned a Task Force to assess their properties and make recommendations regarding their use. A systematic literature review was conducted to explore the use of those instruments in PD and to determine which should be selected for this review. We assessed approaches to evaluate cost of illness (COI), cost effectiveness, and cost utilities, which include the use of direct (standard gamble, time trade-off. and visual analogue scales) and indirect instruments to measure health status and utilities. No validated instruments/models were identified for the evaluation of COI or cost-effectiveness in patients with PD; therefore, no instruments in this group are recommended. Among utility instruments, only a few of these outcome instruments have been used in the PD population, and only limited psychometric data are available for these instruments with respect to PD. Because psychometric data for further utility instruments in conditions other than PD already exist, the standard gamble and time trade-off methods and the EQ-5D (a European quality-of-life health states instrument) and Health Utility Index instruments met the criteria for scales that are "recommended (with limitations)," but only the EQ-5D has been assessed in detail in PD patients. The MDS Task Force recommends further study of these instruments in the PD population to establish core psychometric properties. For the assessment of COI, the Task Force considers the development of a COI instrument specifically for PD, like that available for Alzheimer's disease. © 2013 Movement Disorder Society.
