Genes affected

CACNG1 (HGNC:1405): (calcium voltage-gated channel auxiliary subunit gamma 1) Voltage-dependent calcium channels are composed of five subunits. The protein encoded by this gene represents one of these subunits, gamma, and is one of two known gamma subunit proteins. This particular gamma subunit is part of skeletal muscle 1,4-dihydropyridine-sensitive calcium channels and is an integral membrane protein that plays a role in excitation-contraction coupling. This gene is part of a functionally diverse eight-member protein subfamily of the PMP-22/EMP/MP20 family and is located in a cluster with two family members that function as transmembrane AMPA receptor regulatory proteins (TARPs).

Jul 21, 2021

The c.29G>A (p.R10H) alteration is located in exon 1 (coding exon 1) of the CACNG1 gene. This alteration results from a G to A substitution at nucleotide position 29, causing the arginine (R) at amino acid position 10 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
