Abstract:
We report on a boy, born on term, presenting with a weight loss and a persistent failure to thrive after 10 days despite a normal behavior under bottle-feeding. The clinical examination was normal and biological assessment revealed hyponatremia with hyponatriuria, normal kaliemia and elevated aldosterone values, leading to type I pseudohypoaldosteronism diagnosis. Treatment with salt supplementation allowed growth improvement. The diagnosis was confirmed by the identification of a mutation in the mineralocorticoid receptor. This change was also found in several family members.
