    Description / Table of Contents: Summary Adrenoleukodystrophy (ALD) is an X-linked peroxisomal disease affecting 1 in 20000 males either as cerebral ALD in childhood or as adrenomyeloneuropathy (AMN) in adulthood. Recently, the ALD gene has been identified by positional cloning. We report three males patients with AMN and a fourth patient with juvenile ALD. Biochemical studies showed elevated plasma concentration of saturated very-long-chain fatty acids. Genomic DNA of the patients was analysed for possible sequence variations in the ALD gene by PCR amplification and single strand conformation polymorphism analysis. Three missense mutations (Ser515Phe, Glu267Lys and Arg401Trp) and a 9-bp deletion were detected predicting, respectively, the replacement and absence of amino acids in the deduced amino acid sequence of the ALD protein. In the patients’ families, detection of the respective mutations allows the identification of carriers of ALD/AMN. Mutational screening in ALD families is of practical importance in improving genetic counseling.
    Notes: Zusammenfassung Die Adrenoleukodystrophie (ALD) ist eine X-chromosomal erbliche peroxisomale Stoffwechselerkrankung, deren häufigste Manifestationsform die kindliche ALD gefolgt von der adulten Adrenomyeloneuropathie (AMN) ist. Es werden 3 Patienten mit einer AMN und ein Patient mit einer juvenilen Verlaufsform einer ALD vorgestellt. Die Konzentrationen der überlangkettiger Fettsäuren im Plasma waren bei diesen Patienten pathologisch erhöht. Das ALDP-Gen wurde bei diesen Patienten mittels PCR amplifiziert und mit Hilfe der Einzelstrang-Konformations-Polymorphismus-(SSCP-)Analyse auf Mutationen hin untersucht. Dabei fanden sich drei Missense-Mutationen (Ser515Phe, Glu267Lys, Arg401Trp) und eine Deletion von 9 Nukleotiden. Diese Mutationsanalyse ermöglicht eindeutige Aussagen bezüglich der Anlageträgerschaft für ALD in den jeweils betroffenen Familien und ist daher für eine adäquate humangenetische Beratung von Bedeutung.

    Notes: Summary Three families segregating for X-linked ichthyosis (XLI) were analysed using the full-length STS cDNA probe and an anonymous polymorphic DNA sequence closely linked to the STS gene. In patients from two of the families, submicroscopic chromosomal deletions could be detected using both the STS and the GMGX9 (DXS237 locus) probes. Patients in the third family showed the same hybridization pattern as healthy males following molecular hybridization with either of the probes. The results of DNA analysis (indirect geno-type diagnosis) agree well with those based on the arylsulfatase C/β-gal determination and prove the reliability of the biochemical test. Both methods are discussed for carrier detection, prenatal diagnosis, and genetic conselling.
