Gene Summary:
- DBD Genes Classification
- NALCN is a High Confidence candidate gene classified as Tier AR. AR genes have autosomal recessive inheritance.
- Gene Function
- Voltage-gated ion channel responsible for the resting Na(+) permeability that controls neuronal excitability (PubMed:17448995, PubMed:31409833). NALCN channel functions as a multi-protein complex, which consists at least of NALCN, NALF1, UNC79 and UNC80 (PubMed:32494638, PubMed:33203861). NALCN is the voltage-sensing, pore- forming subunit of the NALCN channel complex (PubMed:17448995). NALCN channel complex is constitutively active and conducts monovalent cations but is blocked by physiological... (Source: Uniprot)
