Clinical definition (Orphanet)
IgG4-related dacryoadenitis and sialoadenitis (Mikulicz disease) is an IgG4-related sclerosing disease characterized by persistent, usually painless, bilateral enlargement of the lacrimal, parotid, and submandibular glands associated with elevated levels of serum immunoglobulin (Ig) G4 and with lymphocyte and IgG4-positive plasmacyte infiltration. It predominantly causes mouth and eye dryness but can also affect other organs such as the lungs, liver, and kidneys, and be accompanied by complications such as autoimmune pancreatitis (AIP), retroperitoneal fibrosis, and tubulointerstitial nephritis.
How rare: How common this is has not been clearly measured.

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?
Not yet — the cause hasn't been pinned down in GenCC.
No strong gene–disease assertion joined for this Orphanet entity.
Phenotypes (Monarch / HPO)
Not enriched in this build — Monarch phenotype joins were not run for this record.
Animal models (Monarch / Alliance)
Not enriched in this build.
Literature
Is anyone studying this?
801
801 papers have been published on this condition. That is a real research literature — still far smaller than common diseases (breast cancer: over 700,000 papers). Median papers in the last 10 years for a rare disease in this dataset (publications denominator n=5449) is 41.
801 papers since the earliest indexed year in this search — median last-10-year count for a rare disease in this dataset is 41 (publications denominator n=5449).

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 2026-07-26This 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.
"IgG4-related dacryoadenitis and sialadenitis" OR "Chronic dacryoadenitis and sialadenitis" OR "Mikulicz disease"
MeSH descriptor terms unioned into the query: Mikulicz' Disease
ClinicalTrials.gov query (quoted phrases + MeSH via query.cond, plus recall-expansion terms when used):
"IgG4-related dacryoadenitis and sialadenitis" OR "Chronic dacryoadenitis and sialadenitis" OR "Mikulicz disease" OR "Mikulicz' Disease"
Study-type breakdown: 0 interventional · 0 observational · 0 expanded access. Only interventional studies enter the trial headline.
Query health: ok — strategies attempted: phrase, mesh; with hits: phrase, mesh

Confidence reasoning
- Preferred label is multi-word and distinctive
- No synonyms dropped by stoplist
- No label/synonym collisions with other diseases in this corpus
