GENE INFORMATION

Gene name

 NALCN (HGNC Symbol)

Synonyms

 bA430M15.1, CanIon, VGCNL1

Description

 Sodium leak channel, non selective (HGNC Symbol)

Entrez gene summary

 NALCN forms a voltage-independent, nonselective, noninactivating cation channel permeable to Na+, K+, and Ca(2+). It is responsible for the neuronal background sodium leak conductance (Lu et al., 2007 [PubMed 17448995]).[supplied by OMIM, Mar 2008]
