Critical Evaluation
Value of the Information & Strength of the Argument
The presentation provides valuable data on the utility of targeted RNA-Seq in resolving uncertain splicing variants in ALS. The argumentation is solid, supported by concrete case studies and quantitative results (11 out of 37 variants reclassified). The methodology is clearly explained, and limitations are acknowledged, such as the pipeline not detecting intron retention. The speaker effectively demonstrates the clinical impact of the approach.
