To determine whether GAP43 expression is reduced in AD brains, we analyzed the AlzData dataset and found that full‐length STMN2 and GAP43 transcripts were significantly decreased in the frontal cortex, temporal cortex, hippocampus, and entorhinal cortex of AD patients compared to age‐matched controls (Figure6A). Here, STMN2 is linked to Alzheimer disease.
