Additional clinical studies have shown that ADNP levels correlate with disease status (cognitive impairments, and schizophrenia) and tauopathy as illustrated above, e.g., ClinicalTrials.gov identifier: NCT01403519—Innovative Biomarkers in Alzheimer's Disease and Frontotemporal Dementia: Preventative and Personalized (24, 53). This evidence concerns the gene ADNP and tauopathy.
