In Figure 3D showing the relationship of p-tau to t-tau concentrations, the different diagnoses influenced the regression in one or another direction - the elevated p-tau in the Alzheimer's disease patients with high t-tau pulled the right end of the line up, while the low p-tau in the ADC and infection patients with elevated t-tau pulled it in the opposite direction. The gene discussed is MAPT; the disease is early-onset autosomal dominant Alzheimer disease.
