CCL25 and posterior cortical atrophy: Inheritance of the CCL25 rs2032887 AG+GG (ORunadjusted = 0.66; 95%CI = 0.46, 0.96), CCL5 rs2107538 GA+AA (ORunadjusted = 0.52; 95%CI = 0.36, 0.76), CCL5 rs2280789 AG+GG (ORunadjusted = 0.60; 95%CI = 0.41, 0.89), and CCL5 rs3817655 GA+AA (ORunadjusted = 0.46; 95%CI = 0.32, 0.68) genotypes were significantly associated with a 34-54% reduction in the risk of developing PCA with chi-square p-values ranging from 0.0001-0.027.
