Intellectual disability-alacrima-achalasia syndrome is a rare, genetic intellectual disability syndrome characterized by delayed motor and cognitive development, absence or severe delay in speech development, intellectual disability, and alacrima. Achalasia/dysphagia and mild autonomic dysfunction (i.e. anisocoria) have also been reported in some patients. The phenotype is similar to the one observed in autosomal recessive Triple A syndrome but differs by the presence of intellectual disability in all affected individuals.

A rare genetic disease characterised by abnormalities in renal ion transport, ectodermal gland homeostasis, and epidermal integrity, resulting in generalised hypohidrosis, heat intolerance, salt-losing nephropathy, electrolyte imbalance, lacrimal gland dysfunction, ichthyosis, and xerostomia. Development of nephrolithiasis and severe enamel wear have also been described. Laboratory findings include hypermagnesaemia, hypokalaemia, hypercalcaemia, and hypocalciuria.
