Gene Overview
Function
NALCN encodes a voltage-independent, non-selective cation channel that conducts a persistent sodium leak current. This channel is essential for maintaining neuronal excitability and resting membrane potential.
Key Functions
Resting Membrane Potential: Provides the persistent sodium leak current that sets the resting membrane potential in [neurons](/entities/neurons)
Neuronal Excitability: Regulates intrinsic neuronal excitability and firing patterns
Calcium Homeostasis: By maintaining sodium gradient, indirectly affects calcium signaling
Motor Neuron Function: Critical for normal motor neuron activity
Disease Associations
Congenital Contracture Syndrome (CCS)
Recessive mutations in NALCN cause CCS, characterized by:
Multiple joint contractures
Developmental delay
Dysmorphic features
Infantile Neuroaxonal Dystrophy (INAD)
NALCN mutations have been identified in INAD, a neurodegenerative disorder characterized by:
Progressive motor and cognitive decline
Axonal spheroids in the nervous system
Early-onset symptoms
Amyotrophic Lateral Sclerosis (ALS)
NALCN dysfunction may contribute to ALS pathogenesis through:
Altered motor neuron excitability
Dysregulated sodium homeostasis
Possible interactions with excitotoxicity mechanisms
