Genes affected

CACNB3 (HGNC:1403): (calcium voltage-gated channel auxiliary subunit beta 3) This gene encodes a regulatory beta subunit of the voltage-dependent calcium channel. Beta subunits are composed of five domains, which contribute to the regulation of surface expression and gating of calcium channels and may also play a role in the regulation of transcription factors and calcium transport.
