Background: Pseudohypoaldosteronism type 1 (PHA1) is a rare disorder of neonatal salt loss unresponsive to mineralocorticoids, requiring salt supplementation. It results from resistance of kidney and/or other tissues to mineralocorticoids, arising from mutations in genes encoding mineralocorticoid receptor (MR: NR3C2; autosomal dominant), or epithelial sodium channel (ENaC) genes (SCNN1A/B/G; autosomal recessive). Milder clinical phenotype associates with ren...
