MMRRC has introduced a new Strain Genetic Quality Control (GQC) report format on select catalog pages, providing a straightforward view of each line’s genetic background and findings. The updated layout is being added to additional strains as QC updates are completed and is designed to help investigators quickly see background estimates, confirm the intended allele, and note genetic features that may influence study design and reporting.

A short video, How to Interpret the MMRRC Strain GQC Report, walks through the format step by step using strain 67067 as an example. This walkthrough highlights where to look first, how to read the main tables and graphics, and how the information can inform model selection, controls, and documentation. As the new report format rolls out across more strains, users can expect a more consistent, transparent view of strain genetics across the MMRRC catalog.
