Conditional analysis at 5q31.1 revealed three independent loci specifically contributing to AD risk: IL13 (MIM 147683, rs848, ORADfull = 1.12, p = 0.0204), KIF3A (MIM 604683, rs 2299009, ORADfull = 1.16, p = 4.1 × 10−4), and SLC22A4 (MIM 604190)/C5orf56 (rs74458173, ORADfull = 1.57, p = 2.0 × 10−4) (Figure 4A, Table 2). This evidence concerns the gene CARINH and Alzheimer disease.
