Genes affected

CACNG6 (HGNC:13625): (calcium voltage-gated channel auxiliary subunit gamma 6) 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 an integral membrane protein that is thought to stabilize the calcium channel in an inactive (closed) state. 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). Alternative splicing results in multiple transcript variants. Variants in this gene have been associated with aspirin-intolerant asthma. [provided by RefSeq, Dec 2010]

The c.728T>G (p.L243R) alteration is located in exon 4 (coding exon 4) of the CACNG6 gene. This alteration results from a T to G substitution at nucleotide position 728, causing the leucine (L) at amino acid position 243 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
