SLC2A3 and early-onset autosomal dominant Alzheimer disease: Both SNPs of the haplotype were associated with altered expression levels of SLC2A3. This gene is a facilitated glucose transporter possibly involved in memory‐related processes as indicated by reduced GLUT3 (SLC2A3) levels in patients with Alzheimer's disease (Liu, Liu, Iqbal, Grundke‐Iqbal, & Gong, 2008).
