eLife Assessment
This study examines age-related, sex-specific gene expression and alternative splicing in humans using the GTEx dataset. Solid evidence is provided to demonstrate that alternative splicing was affected by both sex and age across many tissues in this dataset. Although the authors performed comprehensive computational analyses with useful 'transcriptomic' changes with sex/age, they did not validate their findings with independent longitudinal datasets. This limits the wide impact of this study but can be used as a starting point to examine sex- and age differences in the transcriptome due to alternative splicing.
