Myoclonic Jerking
  • Also typical are short, sharp muscle contractions called myoclonic jerks. Initial signs of this disorder include delayed psychomotor development with progressive deterioration, other motor disorders, or seizures.[brainfoundation.org.au]
Slurred Speech
  • At last follow-up at 11 years, he was wheelchair bound but could walk with support, had severe visual impairment and slow and slurred speech. He was totally dependent for all his daily activities.[pediatricneurosciences.com]
Learning Difficulties
  • Presenting symptoms were visual failure 40 (85%), developmental delay/learning difficulties 28 (60%), behavioural problems 17 (36%), seizures 10 (21%), memory loss 8 (17%), extrapyramidal signs 6 (13%) and gait disturbance/ataxia 5 (11%).[adc.bmj.com]


  • A diagnostic workup is initiated based on patient presentation, however, aside from tests of gene sequencing, and electron and light microscopy, several other ophthalmic imaging modalities can be useful in confirming the diagnosis with characteristic[eyewiki.aao.org]
Generalized Epileptiform Discharges
  • Electroencephalogram (EEG) showed bilateral synchronous generalized epileptiform discharges. Electroretinogram (ERG) was absent and visual evoked potential (VEP) was normal.[pediatricneurosciences.com]
Ventricular Hypertrophy
  • A progressive cardiac involvement with repolarization disturbances, ventricular hypertrophy, and sinus-node dysfunction, ultimately leading to severe bradycardia and/or other conduction abnormalities, starts in the mid-teens.[dovepress.com]

  • Although there currently is no treatment for this condition, making the correct diagnosis is important for appropriate low-vision management, educational planning, and genetic counseling.[ncbi.nlm.nih.gov]

  • There is no effective treatment for CLN3. A major impediment to the testing of potential therapeutic interventions is the lack of well-defined outcome measures.[clinicaltrials.gov]
