BACKGROUND: Acrodermatitis enteropathica (AE) is an autosomal recessively inherited disease caused by a decreased intestinal zinc resorption and characterized by severe dermatitis (preferably hands, feet, mouth, genital region), chronic diarrhoea, retardation of growth and development, alopecia and increased proneness to infections. In 2002 it was shown that mutations in the zinc transporter gene SLC39A4 is the cause of AE. CASE REPORT: Here we report 4 patients with typical clinical signs since early childhood. Under regular substitution with zinc all patients are more or less free of symptoms. The first patient revealed compound-heterozygous missense/nonsense mutations (P200L/ W401X), the three other patients were homozygous for a mutation in intron 1 (c.192 + 19G > A) of the SLC39A4 gene. CONCLUSION: The diagnosis of hereditary acrodermatitis enteropathica can now easily be confirmed by mutation analysis of the SLC39A4 gene.
