FABP7 is also proposed to functionally interact with sortilin, the neuronal receptor for apolipoprotein E (apoE), with apoE3 leading to expression of FABP7 but the apoE4 variant, a major risk factor for Alzheimer’s disease, being associated with reduced FABP7 levels (6). This evidence concerns the gene FABP7 and early-onset autosomal dominant Alzheimer disease.
