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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 25, 2023The c.110G>A (p.R37Q) alteration is located in exon 2 (coding exon 2) of the CACNB3 gene. This alteration results from a G to A substitution at nucleotide position 110, causing the arginine (R) at amino acid position 37 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
