Al. George et al., ASSIGNMENT OF THE HUMAN HEART TETRODOTOXIN-RESISTANT VOLTAGE-GATED NA-SUBUNIT GENE (SCN5A) TO BAND 3P21( CHANNEL ALPHA), Cytogenetics and cell genetics, 68(1-2), 1995, pp. 67-70
The chromosomal location of SCN5A, the gene encoding the principal vol
tage-gated Na+ channel expressed in human heart, has been determined b
y three independent methodologies: somatic cell hybrid mapping, chromo
somal microdissection-polymerase chain reaction, and fluorescence in s
itu hybridization. The SCN5A gene was assigned to the short arm of chr
omosome 3 (band 3p21) by all three approaches. These data are further
evidence that striated muscle Na+ channel genes are dispersed in the g
enome.
