Genes affected
CACNA1G (HGNC:1394): (calcium voltage-gated channel subunit alpha1 G) Voltage-sensitive calcium channels mediate the entry of calcium ions into excitable cells, and are also involved in a variety of calcium-dependent processes, including muscle contraction, hormone or neurotransmitter release, gene expression, cell motility, cell division, and cell death. This gene encodes a T-type, low-voltage activated calcium channel. The T-type channels generate currents that are both transient, owing to fast inactivation, and tiny, owing to small conductance. T-type channels are thought to be involved in pacemaker activity, low-threshold calcium spikes, neuronal oscillations and resonance, and rebound burst firing. Many alternatively spliced transcript variants encoding different isoforms have been described for this gene. [provided by RefSeq, Sep 2011]
CACNA1G-AS1 (HGNC:27377): (CACNA1G antisense RNA 1)

Collection Method: clinical testing

The c.86G>A (p.G29E) alteration is located in exon 1 (coding exon 1) of the CACNA1G gene. This alteration results from a G to A substitution at nucleotide position 86, causing the glycine (G) at amino acid position 29 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
