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.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 11, 2022The c.451C>T (p.R151C) alteration is located in exon 5 (coding exon 5) of the CACNB3 gene. This alteration results from a C to T substitution at nucleotide position 451, causing the arginine (R) at amino acid position 151 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
