The chromosomal location of SCN5A, the gene encoding the principal voltage-gated Na+
channel expressed in human heart, has been determined by three independent
methodologies: somatic cell hybrid mapping, chromosomal micro-dissection-polymerase
chain reaction, and fluorescence in situ hybridization. The SCN5A gene was assigned to the
short arm of chromosome 3 (band 3p21) by all three approaches. These data are further
evidence that striated muscle Na+ channel genes are dispersed in the genome.
Abstract
The chromosomal location of SCN5A, the gene encoding the principal voltage-gated Na+ channel expressed in human heart, has been determined by three independent methodologies: somatic cell hybrid mapping, chromosomal micro-dissection-polymerase chain reaction, and fluorescence in situ hybridization. The SCN5A gene was assigned to the short arm of chromosome 3 (band 3p21) by all three approaches. These data are further evidence that striated muscle Na+ channel genes are dispersed in the genome.
