Enzyme-linked immunosorbent assays comparing GRN plasma levels between GRN mutation carriers and controls. Measurement of GRN plasma levels for a known GRN mutation (left) and the novel GRN mutation (right), Ile256IlefsX27, observed in our study compared with Alzheimer's disease cases and non-demented older controls. GRN, progranulin; mut, mutant; wt, wild-type.
