    Notes: Abstract Since 1974 primary aldosteronism has been diagnosed in 71 patients in our outpatient clinic. Thirty-four patients had a unilateral aldosterone-producing adenoma, whereas bilateral adrenal hyperplasia was diagnosed in 37 patients. Although at the time of diagnosis the mean potassium values were lower and mean aldosterone levels were higher in patients with an adenoma, as compared to those with bilateral hyperplasia, these laboratory data did not allow us to differentiate between the two leading causes of primary aldosteronism in the individual patient due to pronounced overlap of laboratory values between the two groups. During the first few years, a successful differential diagnosis was made by adrenal phlebography and separate sampling of plasma aldosterone in both adrenal veins; later non-invasive imaging techniques such as computed tomography and radionuclide scanning were used. The best results were obtained in patients with adenoma who underwent adrenalectomy. Fifty-six percent of these patients were clinically and biochemically cured; 28% were improved and had normal blood pressure values during drug treatment. In contrast, patients with bilateral hyperplasia were treated pharmacologically, but only in half of the patients could normal blood pressure values be achieved. Two thirds of the male patients developed gynecomastia during spironolactone treatment. As expected, unilateral adrenalectomy was unsuccessful in the 7 patients with bilateral hyperplasia who underwent surgery. Our results confirm that surgical treatment of adrenal adenomas and drug treatment of bilateral hyperplasias are the appropriate therapy in primary aldosteronism. A differential diagnosis cannot be made on the basis of clinical and non-invasive laboratory data alone; imaging techniques have to be included in the diagnostic process. The long-term clinical outcome was more favorable in patients with an adrenal adenoma that can be removed surgically than in patients with idiopathic hyperplasia of both adrenal glands.

    Molecular analysis of yeast chromosome II between CMD1 and LYS2: The excision repair gene RAD16 located in this region belongs to a novel group of double-finger proteins (1992)

    Notes: We have analysed a region some 30 kb centromere distal form PHO5 on the right arm of yeast chromosome II and determined the nucleotide sequence of a 8.95 kb DNA segment from this region. By this analysis we were able to derive the precise location and the transcriptional orientation of CMD1, ALG1, SSN6 and LYS2. An open reading frame of 2370 bp was locatlized between SSN6 and LYS2, which has recently been identified (Schild et al., 1991) to be the RAD16 gene. The putative gene product, 790 amino acids in length, reveals several interesting freatures. It contains a nuclear target singnature and shares several blocks of similarity with the yeast recombinational repair protein RAD54 and the nuclear factor SNF2 (SW12), which is required for teh transcriptioal activation of a number of yeast genes. The similarity blocks in these three proteins are reminiscent of those found in the helicase superfamily. Furthrmore, RAD16 contains a novel ‘double-finger’ motif, which has been encountered in a variety of proteins from different organisms that are suggested to interact with DNA and are involved in diverse functions including site-specific recombination, DNA repair, and transcriptional regulation. The putative gene product of RAD16 then is the first example of a proteins in which the novel double-finger motif is found to be combined with a poteintial DNA helicase framework.

    II. Yeast sequencing reports. Analysis of a 70kb region on the right arm of yeast chromosome II (1994)

    Notes: In the framework of the EC programme for sequencing yeast chromosome II, we have determined the nucleotide sequence of a 70 kb region. Subsequent analysis revealed 35 open reading frames, 14 of which correspond to known yeast genes. From structural parameters and/or similarity searches with entries in the current data libraries, a preliminary functional assessment of several of the putative novel gene products can be made. The gene density in this region amounts to one gene in 1.98 kb. Coding regions occupy 75% of the total DNA sequence. Within the intergenic regions, potential regulatory elements can be predicted. The data obtained here may serve as a basis for a more detailed biochemical analysis of the novel genes. The complete nucleotide sequence of the 70 kb segment as depicted in Figure 1 has been deposited in the EMBL data library under Accession Number X78993.
