DCX is a gene/protein encoding a key neuronal protein involved in synaptic function, signal transduction, and cellular homeostasis. Dysfunction of DCX is associated with neurodegenerative diseases including Alzheimer's disease, Parkinson's disease, and related disorders.
DCX encodes doublecortin, a microtubule-associated protein expressed in migrating neurons during cortical development. DCX promotes microtubule polymerization and stabilization, essential for neuronal migration and axonal guidance. It is a marker for neuronal progenitors and immature neurons.
Expressed in neuronal progenitor cells and migrating neurons during development.
| Disease | Variants | Inheritance | Mechanism |
|---|---|---|---|
| Lissencephaly | Missense, nonsense | X-linked dominant | Impaired neuronal migration |
| Subcortical Band Heterotopia | Various | X-linked dominant | Abnormal neuronal positioning |
