Voltage-dependent L-type calcium channel subunit beta-2 is a protein that in humans is encoded by the CACNB2 gene.[1][2][3]

Clinical significance[edit]

Mutation in the CACNB2 gene are associated with Brugada syndrome, autism, attention deficit-hyperactivity disorder (ADHD), bipolar disorder, major depressive disorder, and schizophrenia.[4]
