SCN2B - sodium voltage-gated channel beta subunit 2 Gene

Homo sapiens

Also known as ATFB14

Gene ID: 6327 | Gene type: protein coding

About SCN2B

Cytogenetic location: 11q23.3 Genomic coordinates (GRCh38): 11:118,162,806-118,176,639 (from NCBI)

This gene has 4 transcripts (splice variants), 190 orthologues, 6 paralogues and is associated with 3 phenotypes. Biased expression in brain (RPKM 17.5), heart (RPKM 5.3) and 5 other tissues.

Summary

The protein encoded by this gene is the beta 2 subunit of the type II voltage-gated Sodium Channel. The encoded protein is involved in cell-cell adhesion and cell migration. Defects in this gene can be a cause of Brugada Syndrome, atrial fibrillation, or sudden infant death syndrome. [provided by RefSeq, Jul 2015]
