Assignment of the human gene for the alpha 1 subunit of the cardiac DHP-sensitive Ca2+ channel (CCHL1A1) to chromosome 12p12-pter

Genomics. 1991 Jul;10(3):835-9. doi: 10.1016/0888-7543(91)90471-p.

Abstract

A human clone corresponding to the gene encoding the alpha 1 subunit of the cardiac dihydropyridine-sensitive calcium channel (CCHL1A1) has been isolated and partially sequenced. Oligonucleotides based on the human sequence were constructed and used in the polymerase chain reaction to amplify specifically this human gene in human-rodent somatic cell hybrids. Using somatic cell hybrids that contained defined regions of human chromosome 12, the human alpha 1 subunit of the cardiac dihydropyridine-sensitive calcium channel has been assigned to the short arm of chromosome 12 in the interval 12p12-pter.
