FranceDiagnosis and screening
In France, an average of 19 months passes from the first symptom to diagnosis of CLN2 disease
A study published in a journal and reviewed by independent scientists. Even so, a single study is not conclusive; it needs to be replicated.
In France, 51 children diagnosed with CLN2 disease in 2017-2023 were studied. The children were usually diagnosed at around 5 years of age. On average, 19 months passed from the first symptom to diagnosis. Most of the children had epileptic seizures. During follow-up, a quarter of the children died.
What does it mean for patients and families?
Early diagnosis allows treatment to start early and the family to receive genetic counseling. The authors recommend earlier referral to specialist centers.
