However, in the AD group, the writer NSUN6 was found to have significantly lower abundance in two regions: in the STG (p = 0.02) and in the WM (p = 0.03), whereas NSUN7 showed higher abundance in the HIP (p = 0.02) (Fig. 1E and 1F, Supplementary Table 8). This evidence concerns the gene NSUN7 and Alzheimer disease.
