Additional Information:

Description: (OMIM) Autosomal recessive pseudohypoaldosteronism type I is characterized by renal salt wasting and high concentrations of sodium in sweat, stool, and saliva. The disorder involves multiple organ systems and is especially threatening in the neonatal period. Laboratory evaluation shows ...
Clinical Description OMIM Cheek and Perry (1958) first described pseudohypoaldosteronism in infancy due to a renal tubular defect; other reports soon followed by Donnell et al. (1959) and Raine and Roy (1962).

Pseudohypoaldosteronism is characterized by salt wasting in ...

Molecular genetics OMIM In 5 families with PHA type I, Chang et al. (1996) identified homozygous mutations in either the SCNN1A gene (600228.0001-600228.0002) or the SCNN1B gene (600760.0003). These mutations cosegregated with the disease, and introduced frameshift, premature termination, or missense ...
