Abstract
The chromosomal localizations of Scnn1b and Scnn1g, genes corresponding to the beta- and gamma-subunits, respectively, of an epithelial non-voltage-gated amiloride-sensitive sodium channel, were determined by analyses of two sets of multilocus crosses using probes generated by polymerase chain reaction and a mouse kidney cortical collecting tubule cell line (M1). Scnn1b and Scnn1g were determined to be closely linked on distal mouse chromosome 7, showing no recombination with Zp2, whereas the gene for the alpha-subunit, Scnn1a, was confirmed to map to distal mouse chromosome 6.
