Benchmarking workflows to assess performance and suitability of germline variant calling pipelines in clinical diagnostic assays.

Benchmarking the performance of complex analytical pipelines is an essential part of developing Laboratory Developed Assays (LDT). Reference samples and benchmark calls published by Genome in a Bottle (GIAB) Consortium have enabled the evaluation of analytical methods. However, the performance of such methods is not uniform across the different regions of the genome/exome and different variant types and lengths. Here we present a scalable and reproducible, cloud-based benchmarking workflow that can be used by clinical laboratories to rapidly access and validate the performance of LDT assays, across their regions of interest and reportable range, using a broad set of benchmarking samples.
