Clinical definition (Orphanet)

A rare neuronal ceroid lipofuscinosis characterized by juvenile or protracted juvenile-onset vision loss due to retinal degeneration/retinopathy (which in several patients may precede the onset of neurological symptoms by some years), , cognitive impairment with a precipitous decline to dementia, motor decline with cerebellar, pyramidal and extrapyramidal features. Associated systemic features may include cardiac abnormalities (including conduction abnormalities, ventricular hypertrophy, atrial flutter/fibrillation and symptomatic bradycardia) and autophagic vacuolar . in juvenile-onset (also known as the classic form of the disease) patients, develop typically within 2-4 years of the onset of visual deterioration. In protracted form, characterized by combined focal and generalized syndrome and neurologic deterioration, and other neurological manifestations appear significantly later compared to classic form and symptoms are milder. This is the most common form of ceroid lipofuscinosis and is widespread across Western countries.

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 (CLN3).

GenCC classification: Definitive.

Phenotypes (Monarch / HPO)

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

Clinical research

Is a treatment being tested?

4

interventional trials for this specific condition

4 interventional trials matched this specific condition name; 1 currently recruiting in our sample.

Data as of 27 July 2026

4 interventional trials — more than 73% of diseases in the trials denominator have none at all (5114 of 7003; this disease is at the 86.7th percentile).

low confidence · 86.7th percentile (trials denominator)

Recruiting interventional trials

From the matched ClinicalTrials.gov set

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

Observational and natural-history studies

4 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

Likely covered — the policy lists Neuronal ceroid lipofuscinosis as a category (Group 3), and this condition is a form of it. Confirm eligibility with a Centre of Excellence.

Group 3 — high-cost / lifelong therapy with careful selection

Up to ₹50 lakh per patient

Financial support at notified Centres of Excellence is the figure commonly cited in recent MoHFW/PIB statements. Many Group 3 patients also use the MoHFW voluntary-contribution / crowdfunding portal.

Eligibility and patient selection rules change. Verify with a CoE; the crowdfunding portal is a separate mechanism from CoE funding. Verify
