RELN is a gene/protein encoding a key neuronal protein involved in synaptic function, signal transduction, and cellular homeostasis. Dysfunction of RELN is associated with neurodegenerative diseases including Alzheimer's disease, Parkinson's disease, and related disorders.
RELN encodes reelin, a large extracellular matrix protein secreted by Cajal-Retzius cells during brain development. Reelin plays critical roles in neuronal migration, positioning, and synaptic plasticity. It binds to lipoprotein receptors (VLDLR and ApoER2) to activate downstream signaling pathways that regulate cytoskeletal dynamics.
Expressed in Cajal-Retzius cells during development and in certain neurons in the adult brain.
| Disease | Variants | Inheritance | Mechanism |
|---|---|---|---|
| Lissencephaly | Missense, truncating | Autosomal recessive | Impaired neuronal migration |
| Schizophrenia | Risk variants | Susceptibility | Altered synaptic function |
| Autism | Risk variants | Susceptibility | Impaired neural development |
