OMIM : ⁵⁷ Autosomal dominant pseudohypoaldosteronism type I is characterized by salt wasting resulting from renal unresponsiveness to mineralocorticoids. Patients may present with neonatal renal salt wasting with hyperkalaemic acidosis despite high aldosterone levels. These patients improve with age and usually become asymptomatic without treatment. Some adult patients with the disorder may have elevated aldosterone levels, but no history of clinical disease. This observation suggests that only those infants whose salt homeostasis is stressed by intercurrent illness and volume depletion develop clinically recognized PHA I (summary by Geller et al., 1998). Autosomal recessive pseudohypoaldosteronism type I (PHA1B; 264350), caused by mutation in any one of 3 genes encoding the epithelial sodium channel (ENaC), is a similar but more severe systemic disorder with persistence into adulthood.

MalaCards based summary : Pseudohypoaldosteronism, Type I, Autosomal Dominant, also known as autosomal dominant pseudohypoaldosteronism type 1, is related to pseudohypoaldosteronism, type i, autosomal recessive and pseudohypoaldosteronism, and has symptoms including diarrhea and vomiting. An important gene associated with Pseudohypoaldosteronism, Type I, Autosomal Dominant is NR3C2 (Nuclear Receptor Subfamily 3 Group C Member 2), and among its related pathways/superpathways are Transport of glucose and other sugars, bile salts and organic acids, metal ions and amine compounds and Neuropathic Pain-Signaling in Dorsal Horn Neurons. Affiliated tissues include kidney, and related phenotypes are hyperactive renin-angiotensin system and increased circulating renin level

UniProtKB/Swiss-Prot : ⁷⁵ Pseudohypoaldosteronism 1, autosomal dominant: A salt wasting disease resulting from target organ unresponsiveness to mineralocorticoids. PHA1A is a mild form characterized by target organ defects confined to kidney. Patients may present with neonatal renal salt wasting with hyperkalaemic acidosis despite high aldosterone levels. These patients improve with age and usually become asymptomatic without treatment.

NIH Rare Diseases : ⁵³ Autosomal dominant pseudohypoaldosteronism type 1 is a disorder of electrolyte metabolism characterized by excess loss of salt in the urine, failure to thrive and dehydration. Patients typically present in the newborn period, improve with age, and usually become asymptomatic without treatment. Some adult patients with the disorder may have elevated aldosterone levels, but no history of clinical disease. Autosomal dominant pseudohypoaldosteronism type 1 (PHA1A) exhibits autosomal dominant inheritance with variable expression. It is caused by by mutations in the mineralocorticoid receptor gene (NR3C2).  

Disease Ontology : ¹² A pseudohypoaldosteronism characterized by Salt wasting resulting from renal unresponsiveness to mineralocorticoids that has material basis in heterozygous mutation in the NR3C2 gene on chromosome 4q31.
