Chromosomal localization of the human genes for {alpha}{sub 1A}, {alpha}{sub 1B}, and {alpha}{sub 1E} voltage-dependent Ca{sup 2+} channel subunits
- CRBM-CNRS, Montpellier (France); and others
The {alpha}{sub 1} subunit genes encoding voltage-dependent Ca{sup 2+} channels are members of a gene family. We have used human brain cDNA probes to localize the neuronal isoform genes CACNL1A4 ({alpha}{sub 1A}), CACNL1A5 ({alpha}{sub 1B}), and CACNL1A6 ({alpha}{sub 1E}) to 19p13, 9q34, and 1q25-q31, respectively, using fluorescene in situ hybridization on human chromosomes. These genes are particularly interesting gene candidates in the pathogenesis of neuronal disorders. Although genetic disorders have been linked to loci 9q34 and 19p13, no genetic disease related to Ca{sup 2+} signaling defects has yet been linked to these loci. 22 refs., 2 figs., 1 tab.
