Gene expression levels for selected AD-related genes: normalized probe intensities for ADAM9 (A), RTN4 (B), and LRPAP1 (C) at 29 years of age in relation to prenatal (umbilical cord) blood lead concentrations. Data points from samples with cord blood lead level concentrations < 10 μg/dL (n = 26) were not used to identify genes whose expression was significantly associated with blood lead levels > 10 μg/dL (n = 10) and are plotted for reference only.
