ABI3 and Alzheimer disease: When we quantified the expression of this isoform, we found that it was rare, correlated well with total ABI3 expression (p < 0.0001, r2 = 0.702, Figure 4G), but was also not influenced by either AD neuropathology (p > 0.05, Figure 4G) or AD genetics (p > 0.05, Figure 4H,I).
