Role of Np in neurodegeneration is also suggested by demonstrating its involvement in tissue reorganization in Alzheimer’s disease (AD) [6], whereas its role in neurodevelopment and brain maturation is further argued by data analysis showing that the Np gene expression (NPTN) steadily increases from the prenatal period to adulthood when the expression is highest [7]. The gene discussed is NPTN; the disease is Alzheimer disease.
