Assignment of the human heart tetrodotoxin-resistant voltage-gated Na+ channel alpha-subunit gene (SCN5A) to band 3p21.
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 microdissection-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.
