Triple A syndrome

Glucocorticoid deficiency with achalasia, Achalasia-Addisonianism-Alacrimia syndrome, Allgrove syndrome


Type of disease: Rare conditions

Triple A syndrome is an inherited condition characterized by three specific features: achalasia, Addison disease, and alacrima (a reduced or absent ability to secrete tears). Most people with triple A syndrome have all three of these features, although some have only two. Affected individuals may also have dysautonomia, developmental delay, intellectual disability, speech problems, a small head size, muscle weakness, movement problems, peripheral neuropathy, and optic atrophy. Many of the neurological symptoms of triple A syndrome worsen over time. Triple A syndrome is caused by mutations in the AAAS gene and is inherited in an autosomal recessive pattern.
