triple A syndrome
Definition An autosomal recessive condition (OMIM:231550) characterised by glucocorticoid deficiency, achalasia of the gastric cardia, defective tear formation–alacrima and often changes of autonomic dysfunction. Over time, many patients develop neurologic disease–e.g., polyneuropathy with sensory, motor, and autonomic components, long-tract degeneration, parkinsonism, and mild dementia
Molecular pathology Defects of AAAS, which encodes a regulatory protein that is thought to be involved in normal development of the peripheral and central nervous systems.
