    • Seventy-five index cases with early onset of severe hypertension, many with suppressed renin and/or aldosterone levels, were screened for mutation by single-stranded conformational polymorphism (SSCP) analysis of all coding regions of MR (3). Identified variants were subjected to DNA sequence analysis (3). All clinical studies were approved by the Yale Human Investigation Committee.

    • Lod scores were calculated with the LINKAGE program (20), specifying early onset of severe hypertension as an autosomal dominant trait with complete penetrance, a phenocopy rate of 0.001, and a mutant allele frequency of 0.0001.

    • L810 were indistinguishable, and multiple independent preparations of both plasmids yielded indistinguishable results in heterodimer experiments.

    • L810 models were generated from the PR crystal structure (13) with the Turbo Frodo molecular graphics program (http://afmb.cnrs-mrs.fr/ TURBO_FRODO). Residues abutting the ligand were altered to match the MR sequence (G773A, M810S, Y941F, and M960L). In addition, the E774G substitution was incorporated to reflect the rotational freedom C774 confers on helix 3 in MR. The geometry was regularized with Turbo Frodo. Coordinates for aldosterone (23) were superimposed upon progesterone. Parameters for aldosterone were generated with HIC-Up (24). The 21-hydroxyl group was rotated to form a favorable interaction with the N770 side chain (14).

    • 3H]aldosterone and competitor steroid at 0°C in a total volume of 200 μl, and then incubated with 100 μl of a 50% slurry of hydroxyapatite in binding buffer. Samples were centrifuged, washed twice in binding buffer, and then resuspended in ethanol and prepared for scintillation counting. The value for 100% binding was determined by subtracting the number of counts per minute bound in the presence of 500-fold excess of unlabeled aldosterone from the counts bound in the absence of competitor. Nonspecific binding was determined with a 500-fold excess of unlabeled aldosterone. No specific binding was seen in mock-transfected cells.
