Highlighting some genes for further study, KIF5A is a brain-disease-relevant gene with a large amount of its relative abundance stemming from isoforms discovered between 2019 and 2023, where the four new isoforms comprise 62.4%, 57.0%, and 79.8% of total gene expression for frontal cortex, putamen, and cerebellar hemisphere, respectively (Fig. 3d). This evidence concerns the gene KIF5A and glycogen storage disease VI.
