The skeletal muscle dihydropyridine receptor consists of five subunits and fulfils an essential role in excitation-contraction coupling. A genomic clone for the human gamma subunit was used to map the gene (CACNLG) to chromosome band 17q24 by in situ hybridization. Contained within the gene is a 416-bp polymorphic repetitive DNA element that is potentially useful as a genetic marker.
