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 GeneticsFeb 22, 2023The c.91G>A (p.V31I) 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 91, causing the valine (V) at amino acid position 31 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
