A novel DNA sequence variation in the first genetically confirmed allgrove syndrome in iran.

Allgrove syndrome or triple-A syndrome is an autosomal recessive disorder characterized by adrenal insufficiency, achalasia and alacrima. Affected patients may also present with a constellation of central and peripheral nervous system manifestations. The gene for Allgrove syndrome (ALADIN) is located on chromosome 12q13. Here we report a 23-year-old man with alacrimia, achalasia, optic atrophy and progressive amyotrophic lateral sclerosis-like presentations. Sequencing of ALADIN gene showed a novel 6-bp sequence variant that the patient was homozygous and his father was heterozygous for the defect. A probable mechanism of action of this newly diagnosed missense mutation would be to cause abnormal splicing of the ALADIN gene.
