Stages with a signal
Clinical definition (Orphanet)
A rare multiple anomalies/ syndrome characterized by severe global , osteogenesis imperfecta, presence of wormian bones, , ocular abnormalities (blue sclerae, optic atrophy, retinal detachment), and facial features (including frontal bossing, low anterior hairline, medial flare of the eyebrows, long eyelashes, hypertelorism, depressed nasal bridge, and low-set, large ears). There have been no further descriptions in the literature since 1994.
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.”
1/6 stages with a signal
Search queries returned nothing — this usually means a naming mismatch, not proof that nothing exists.

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.

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.

Clinical research
Is a treatment being tested?
0
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). 60 trials are registered for osteogenesis imperfecta, the broader category — shown separately because they may or may not enrol this specific subtype.
Data as of 11 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.

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 2026-07-26Likely covered — the policy lists Osteogenesis imperfecta as a category (Group 2), and this condition is a form of it. Confirm eligibility with a Centre of Excellence.
Group 2 — long-term / lifelong lower-cost interventions
NPRD envisages State Government support for dietary formulae, hormones, and other lower-cost interventions. This is a different route from the central CoE ₹50 lakh pathway; ask your state health department and a CoE which channel applies.
Central CoE funding may also apply depending on current rules — confirm with a notified Centre of Excellence. Do not assume the ₹50 lakh ceiling covers Group 2 by default. Verify

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.
"Osteogenesis imperfecta-retinopathy-seizures-intellectual disability syndrome" OR "Al Gazali-Nair syndrome"
ClinicalTrials.gov query (quoted phrases + MeSH via query.cond, plus recall-expansion terms when used):
"Osteogenesis imperfecta-retinopathy-seizures-intellectual disability syndrome" OR "Al Gazali-Nair syndrome"
Study-type breakdown: 0 interventional · 0 observational · 0 expanded access. Only interventional studies enter the trial headline.
Parent-category trials query:
"osteogenesis imperfecta"
Query health: broken — strategies attempted: phrase; with hits: none
Parent literature probe: retinal disorder (MONDO:0005283) — 1881 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 retinal disorder has 1881 — literature likely indexed under a broader name
