Nrxn1 Gene is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
NRXN1 (Neurexin-1) is a gene encoding a cell adhesion molecule essential for synaptic formation, function, and maintenance. It is one of the largest genes in the human genome. [1]

NRXN1 encodes neurexin-1, a presynaptic cell adhesion molecule that mediates synaptic contact between neurons and is essential for synapse formation and function.
Neurexin-1 has two major isoforms:
NRXN1 is expressed throughout the brain:
NRXN1 is a major ASD risk gene:
NRXN1 variants associated with schizophrenia:
NRXN1 involvement in AD:
NRXN1 in PD:
NRXN1 mutations cause epilepsy:
No direct therapeutic targeting yet, but approaches include:
The study of Nrxn1 Gene has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
