Clinical definition (Orphanet)

A rare, genetic, non-syndromic developmental defect of the eye disorder, with high clinical and genetic heterogeneity, most frequently characterized by bilateral, symmetrical, non- cataracts which present at birth or in early-childhood. Additional ocular manifestations (e.g. anterior segment dysgenesis, colobomas, nystagmus, microcornea, microphthalmia, myopia) may be associated, however other organs/systems are usually not affected.

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?

Probably — there is moderate evidence for BFSP2, CRYBB3, EPHA2.

GenCC classification: Moderate.

Phenotypes (Monarch / HPO)

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

interventional trials for this specific condition

8 interventional trials matched this specific condition name; 3 currently recruiting in our sample. 1,236 trials are registered for cataract, the broader category — shown separately because they may or may not enrol this specific subtype.

Data as of 27 July 2026

8 interventional trials — more than 73% of diseases in the trials denominator have none at all (5114 of 7003; this disease is at the 90.6th percentile).

From the matched ClinicalTrials.gov set

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

Broader category: cataract

1,236

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

Worth raising with a clinician. How we count trials.

Recruiting under the broader category

Observational and natural-history studies

2 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.

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.

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

"Early onset non-syndromic cataract" OR "BFSP2" OR "CRYBB3" OR "EPHA2"

Recall-expansion terms: BFSP2, CRYBB3, EPHA2

Interventional trials matched via: 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: 8 interventional · 2 observational · 0 expanded access. Only interventional studies enter the trial headline.

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 cataract has 197446 — literature likely indexed under a broader name
