Abstract

Adrenoleukodystrophy (ALD) and adrenomyeloneuropathy (AMN) are allelic X-chromosomal disorders of peroxisomal lipid metabolism due to mutations of the ABCD1-gene, leading, respectively, to leukoencephalopathy or myeloneuropathy in male patients. We report a family with two symptomatic carriers in subsequent generations who both suffer from symptoms of an AMN. In both patients, molecular genetic testing revealed a heterozygous c.1552C>T-transition (p.Arg518Trp) in exon 6 of ABCD1. Our observations underline the importance of identifying such symptomatic ALD carriers.
