CALCIUM CHANNEL, VOLTAGE-DEPENDENT, GAMMA-1 SUBUNIT; CACNG1


Alternative titles; symbols

CALCIUM CHANNEL, L TYPE, GAMMA POLYPEPTIDE; CACNLG
CALCIUM CHANNEL, NEURONAL DIHYDROPYRIDINE-SENSITIVE, GAMMA SUBUNIT


HGNC Approved Gene Symbol: CACNG1

Cytogenetic location: 17q24.2     Genomic coordinates (GRCh38): 17:67,044,554-67,056,797 (from NCBI)


TEXT

Cloning and Expression

Powers et al. (1993) cloned human CACNG1, which they designated CACNLG, from a fetal skeletal muscle cDNA library. The deduced CACNLG protein contains 222 amino acids. RT-PCR analysis detected CACNLG transcripts in human and mouse skeletal muscle, but not in human brain or cardiac muscle or mouse brain, cardiac muscle, spleen, kidney, liver, or stomach.


Gene Structure

Powers et al. (1993) determined that the CACNLG gene has 4 exons spanning 12.5 kb.


Mapping

Powers et al. (1993) mapped the CACNLG gene to chromosome 17q23 in the same region as the CACNB1 gene (114207). They identified a polymorphic dinucleotide repeat within the CACNLG gene.

Iles et al. (1993) estimated that the CACNLG locus is about 19 cM distal to the SCN4A (603967) and GH1 (139250) loci, which in turn are about 32 cM telomeric of the HOX2B locus (142961), on chromosome 17. Iles et al. (1993) mapped the CACNLG gene to 17q24 by in situ hybridization. They also identified a polymorphic repetitive DNA sequence in the gene.


Molecular Genetics

Exclusion Studies

Iles et al. (1993) excluded the CACNLG gene as the site of the mutation in a considerable number of families with malignant hyperthermia susceptibility in which there was no linkage to chromosome 19.
