No current therapies are available for the progressive neurological dysfunction, and the treatments for other aspects of triple A syndrome including the adrenal failure are aimed at symptom relief rather than prevention or cure ( 1, 3).Īdrenal hypofunction does not occur in the immediate postnatal period but at a variable time after this, suggesting progressive adrenal destruction or degeneration ( 4).

The features of the disorder tend to be progressive, and the full clinical picture may develop over many years. The spectrum of clinical manifestations is unique and encompasses a range of phenotypic abnormalities that can be highly heterogeneous even within affected families ( 2). Triple A syndrome is an autosomal recessive disorder characterized by adrenal failure, achalasia of the cardia, alacrima (absence of tears), and a variety of progressive central, peripheral, and autonomic neurological defects ( 1). Taken together, this work offers a plausible mechanism for the progressive clinical features of triple A syndrome. Apoptosis of neuronal cells induced by hydrogen peroxide was significantly reduced by transfection of AAAS or by FTH1 or maximally by both genes together. In addition to its well known iron storage role, FTH1 has been shown to protect the nucleus from oxidative damage. Therefore, FTH1 nuclear translocation is enhanced when ALADIN is coexpressed in these cells. Cells transfected with FTH1 and visualized by confocal microscopy had very little nuclear FTH1, but when cotransfected with AAAS, FTH1 is readily visible in the nuclei. Immunoblotting showed that fibroblasts from triple A patients (with known AAAS mutations) lack nuclear FTH1, suggesting that the nuclear translocation of FTH1 is defective. This interaction was confirmed by both co-immunoprecipitation and fluorescence lifetime imaging microscopy-fluorescence resonance energy transfer studies. Nonidentical cDNA fragments were identified from both a HeLa S-3 cell and human cerebellar cDNA library that encoded the full-length ferritin heavy chain protein (FTH1). Our aim was to elucidate the functional role of ALADIN by determining its interacting protein partners using the bacterial two-hybrid (B2-H) technique.

The majority of cases are associated with mutations in the AAAS gene, which encodes a novel, 60-kDa WD-repeat nuclear pore protein, alacrima-achalasia-adrenal insufficiency neurological disorder (ALADIN) of unknown function. Triple A syndrome is a rare autosomal recessive disorder characterized by ACTH-resistant adrenal failure, alacrima, achalasia, and progressive neurological manifestations.
