Clinical definition (Orphanet)

A form of pseudohypoaldosteronism type 1 characterized by mild mineralocorticoid resistance that is restricted to the kidneys and that usually improves in early childhood. Typical presentation is in the period with weight loss, , vomiting and dehydration in association with hyponatremia, hyperkalemia and as well as elevated aldosterone and renin levels.

How rare: 1-9 / 100 000 — about one to nine people per hundred thousand.

Research stages

Trial readiness signals

Where this condition sits on an open-data research pipeline — not how close a treatment is, and not medical advice. Empty stages often mean “not in these databases under this Mondo ID,” not “impossible.”

Biology

Genes and phenotypes

Gene–disease validity from GenCC, plus phenotypes and animal models joined from Monarch Initiative via Mondo ID — not a clinical diagnosis aid.

Do we know what causes it?

Yes — we know a specific gene responsible (NR3C2).

GenCC classification: Definitive.

0

Interventional trials for the parent category, exclusive of NCT IDs already counted above. Eligibility for this subtype is not guaranteed.

Parent-category matching found a broader label but no interventional trials under it. How we count trials.

Other registries (secondary)

Broader net from EU CTIS, ISRCTN, and ICTRP when available — deduped against ClinicalTrials.gov IDs already counted above. Dual-model LLM relevance gates what we keep. These rows are not added to the interventional headline.

No secondary-registry studies passed dual-model relevance for this condition name (after dedupe).

Where to find support

Condition-specific patient organisations, when Orphanet lists them, are on the disease’s Orphanet page. We also link umbrella groups that support undiagnosed and ultra-rare families.

India — NPRD

Last verified 2026-07-26

This ORPHAcode is not on our curated NPRD list (direct or Mondo-parent match). That does not decide clinical eligibility; families in India should ask a notified Centre of Excellence about current coverage.

Hand-curated for this project. ORPHAcode mappings are best-effort and may be incomplete or imprecise for umbrella categories. Parent (Mondo) matches mean the policy lists a broader category — confirm eligibility with a Centre of Excellence. Financial entitlements summarised from public policy statements and may change. This is not official government guidance.

How we counted this

Europe PMC query (preferred label + any corrected label + Orphanet and Mondo exact synonyms, stoplisted; unioned with resolved MeSH labels when available). UMLS / OMIM / NCIT cross-references are stored on the overview but are not added to the query string.

("Renal pseudohypoaldosteronism type 1" OR "Autosomal dominant PHA1" OR "Autosomal dominant pseudohypoaldosteronism type 1" OR "Renal PHA1" OR "PHA1A" OR "pseudohypoaldosteronism type i, autosomal dominant") OR ("NR3C2" OR "NR3C2 syndrome" OR "NR3C2-related")
