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.

The c.517G>A (p.V173M) alteration is located in exon 7 (coding exon 7) of the CACNB3 gene. This alteration results from a G to A substitution at nucleotide position 517, causing the valine (V) at amino acid position 173 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
