A systematic review of family-based amyotrophic lateral sclerosis (ALS) studies resolved two pedigrees, nominating FUS and SYNE1 as the causal genes. Reanalysis of four other unresolved regions found no convincing evidence of new ALS-causing variants. The authors propose combining extended ALS families into “super-pedigrees” to improve gene discovery.
Why this matters
The findings may help researchers design future studies to identify shared genetic risk factors in ALS, particularly when individual families are small or genetically complex. This research does not change treatment for people living with ALS now.
Limitations and context
This was a review and reanalysis of previously studied family-based data, not a treatment study. The unresolved regions came from only five pedigrees, and the authors report that three remained unresolved. The proposed “super-pedigree” approach still needs to be tested in future research.
