RESUMEN

We report three patients presenting symptoms of tetany at eleven months, five years and seven years. They had hypocalcemia hypomagnesemia, hyperphosphatemia and elevated phosphate tubular reabsorption. PTH serum levels were decreased and cAMP urinary excretion was very low. Clinical and biological findings suggest hypoparathyroidism, but due to peculiar phenotype of one patient differential diagnosis is established.
