Genes affected

CACNB1 (HGNC:1401): (calcium voltage-gated channel auxiliary subunit beta 1) The protein encoded by this gene belongs to the calcium channel beta subunit family. It plays an important role in the calcium channel by modulating G protein inhibition, increasing peak calcium current, controlling the alpha-1 subunit membrane targeting and shifting the voltage dependence of activation and inactivation. Alternative splicing occurs at this locus and three transcript variants encoding three distinct isoforms have been identified. [provided by RefSeq, Jul 2008]

The c.1195G>A (p.E399K) alteration is located in exon 13 (coding exon 13) of the CACNB1 gene. This alteration results from a G to A substitution at nucleotide position 1195, causing the glutamic acid (E) at amino acid position 399 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
