Hypohidrosis-Electrolyte Imbalance-Lacrimal Gland Dysfunction-Ichthyosis-Xerostomia Syndrome

A rare genetic disease characterized by abnormalities in renal ion transport, ectodermal gland homeostasis, and epidermal integrity, resulting in generalized 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 hypermagnesemia, hypokalemia, hypercalcemia, and hypocalciuria.
