{"symbol":"SCN4B","synonyms":["ATFB17","NAVBETA4","LQT10"],"name":"sodium channel, voltage gated, type IV beta subunit","description":"The protein encoded by this gene is one of several sodium channel beta subunits. These subunits interact with voltage-gated alpha subunits to change sodium channel kinetics. The encoded transmembrane protein forms interchain disulfide bonds with SCN2A. Defects in this gene are a cause of long QT syndrome type 10 (LQT10). Three protein-coding and one non-coding transcript variant have been found for this gene.[provided by RefSeq, Mar 2009]","ncbiEntrezGeneId":6330,"ncbiEntrezGeneUrl":"http://www.ncbi.nlm.nih.gov/gene/6330","proteins":[{"symbol":"SCN4B_HUMAN","href":"/api/1.0/protein/SCN4B_HUMAN"}],"hgncRootFamilies":[{"name":"Immunoglobulin superfamily domain containing","href":"/api/1.0/gene_family/Immunoglobulin+superfamily+domain+containing"}]}
