Stages with a signal
Clinical definition (Orphanet)
A rare autoinflammatory syndrome with immune deficiency characterized by recurrent infections (bacterial and viral) due to NCKAP1L mutations. Patients are present with recurrent respiratory tract infections and recurrent pneumonia mostly causing bronchiectasis, bacteremia, and meningitis. Patients also have systemic hyperinflammation which mostly presents with an atopic disease, , and lymphoproliferation. Cytokine overproduction, antibody abnormalities, elevated IgE levels and increased B cells are observed.
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.”
0/6 stages with a signal
Search queries returned nothing — this usually means a naming mismatch, not proof that nothing exists.
- Gene identifiedNot found
No GenCC disease–gene assertion in this build

Query returned nothing — not evidence of absence Source

No HPO disease–phenotype associations via Monarch for these Mondo IDs

Broken query — trial zero not trusted
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?
Not yet — the cause hasn't been pinned down in GenCC.
No strong gene–disease assertion joined for this Orphanet entity.
Phenotypes (Monarch / HPO)
None returned for this Mondo ID. That often means “not linked under this ID,” not “no clinical features.”
Animal models (Monarch / Alliance)
None returned for this Mondo ID. Empty here is not proof that no model organism work exists under another name or gene.

Therapies
Designations, candidates, and chemicals
FDA OOPD and EMA orphan designations, Open Targets clinical candidates, and CTD chemical associations via MyDisease.info. These never change the interventional-trial headline.
Orphan designation (FDA · EMA)
No designation matched this disease via UMLS or preferred name on the FDA OOPD mirror or EMA orphan register. Absence here is not proof that none exists under another wording.
Open Targets candidates
No drugs or clinical candidates returned for this Mondo ID on Open Targets.
CTD chemicals (MyDisease.info)
No CTD chemical associations returned for this Mondo ID.

interventional trials for this specific condition
No interventional trial testing a treatment matched this specific condition name on ClinicalTrials.gov (observational studies and pan-disease registries are listed separately when present).
Data as of 9 September 2026
No matched interventional trials. This is true for 77.2% of diseases in the trials denominator (5501 of 7126). Here are the researchers publishing on it.

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.

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 2026-07-26This 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.
"Familial hyperinflammatory lymphoproliferative immunodeficiency" OR "HEM1 deficiency syndrome" OR "NCKAP1L-associated hyperinflammatory disorder"
ClinicalTrials.gov query (quoted phrases + MeSH via query.cond, plus recall-expansion terms when used):
"Familial hyperinflammatory lymphoproliferative immunodeficiency" OR "HEM1 deficiency syndrome" OR "NCKAP1L-associated hyperinflammatory disorder" OR "immunodeficiency-associated lymphoproliferative disease"
Recall-expansion terms: immunodeficiency-associated lymphoproliferative disease
Study-type breakdown: 0 interventional · 0 observational · 0 expanded access. Only interventional studies enter the trial headline.
Query health: broken — strategies attempted: phrase, recall-expansion; with hits: none
Parent literature probe: neoplasm (MONDO:0005070) — 2267988 hits
Run this search on ClinicalTrials.gov
Confidence reasoning
- Preferred label is multi-word and distinctive
- No synonyms dropped by stoplist
- No label/synonym collisions with other diseases in this corpus
- Zero publications but parent term neoplasm has 2267988 — literature likely indexed under a broader name
