2025 update of the National French consensus on gene lists for the diagnosis of muscle diseases using high-throughput sequencing

Diagnosing rare muscle diseases can be challenging due to their genetic heterogeneity. The French National Network for Rare Neuromuscular Diseases (FILNEMUS) has previously established a pioneering nationwide strategy based on gene lists organized in 13 phenotype-specific gene panels. We now revise these lists and add recently described genes. Using data collected from all FILNEMUS diagnostic laboratories, we also establish a "Major Muscle Genes" panel that includes genes responsible for the most frequent genetic muscle diseases. The updated diagnostic strategy of the FILNEMUS network will help reduce the turn-around time for genetic results and facilitate rapid access to the French national genome sequencing platforms.
