Clinical definition (Orphanet)

Pro-opiomelanocortin (POMC) deficiency is a form of monogenic obesity resulting in severe early-onset obesity, adrenal insufficiency, red hair and pale skin.

How rare: <1 / 1 000 000 — fewer than one in a million. In a city the size of Kolkata, that might mean on the order of fifteen people.

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 (POMC).

GenCC classification: Strong.

Phenotypes (Monarch / HPO)

Not enriched in this build — Monarch phenotype joins were not run for this record.

Clinical research

Is a treatment being tested?

5

interventional trials for this specific condition

5 interventional trials matched this specific condition name; none in our sample are currently recruiting.

Data as of 27 July 2026

5 interventional trials — more than 73% of diseases in the trials denominator have none at all (5114 of 7003; this disease is at the 87.9th percentile).

Recruiting interventional trials

From the matched ClinicalTrials.gov set

5 interventional trials matched after quoted-phrase search and title/condition post-filter.

No currently recruiting studies in the matched set. Open the same search on ClinicalTrials.gov.

Observational and natural-history studies

3 observational studies match this condition. These do not test a treatment and are not counted in the interventional-trial headline, but they are genuine research: natural-history work often defines the endpoints needed for a future rare-disease trial, and families may be able to enroll.

None of the matched observational studies is currently listed as recruiting.

Where to find support

We do not yet link condition-specific patient organisations. These umbrella groups 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.

"Obesity due to pro-opiomelanocortin deficiency" OR "POMC deficiency" OR "obesity, adrenal insufficiency, and red hair due to POMC deficiency"

MeSH descriptor terms unioned into the query: Proopiomelanocortin Deficiency

ClinicalTrials.gov query (quoted phrases + MeSH via query.cond, plus recall-expansion terms when used):

"Obesity due to pro-opiomelanocortin deficiency" OR "POMC deficiency" OR "obesity, adrenal insufficiency, and red hair due to POMC deficiency" OR "Proopiomelanocortin Deficiency" OR "POMC"

Recall-expansion terms: POMC

Interventional trials matched via: phrase, recall-expansion (mesh = registered under a MeSH descriptor no name phrase would catch; recall-expansion = gene / selected parent terms used only for trials).

Study-type breakdown: 5 interventional · 3 observational · 0 expanded access. Only interventional studies enter the trial headline.

Query health: ok — strategies attempted: phrase, mesh, recall-expansion; with hits: phrase, mesh, recall-expansion

Confidence reasoning

  • Preferred label is multi-word and distinctive
  • No synonyms dropped by stoplist
  • No label/synonym collisions with other diseases in this corpus
  • Publication count (354) is high for prevalence class "<1 / 1 000 000" — confidence capped at medium
