Living with Neuronal ceroid lipofuscinosis 5

A type of NCL (CLN5) with poor coordination, seizures, muscle twitches, and vision loss, mostly in the Finnish population.

Understanding Neuronal ceroid lipofuscinosis 5

Neuronal ceroid lipofuscinosis 5 (CLN5-NCL) is a rare condition that affects the nervous system.

Affected people may have loss of muscle coordination (ataxia), seizures that don't respond to medicines, muscle twitches (myoclonus), vision loss, and decline in thinking and movement. It occurs mostly in the Finnish population. GARD lists onset in infancy.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Seizures
  • Muscle twitches (myoclonus)
  • Vision loss that gets worse
  • Limb tremor
  • Loss of ability to walk
  • Loss of brain tissue

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include brain and nervous system specialists, eye disease specialists, genetic specialists and seizure and epilepsy specialists.

  3. Consider genetic testing

    Changes in CLN5 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

    BDSRA Foundation and Epilepsy Foundation may keep lists of experts for this condition.

GenesCLN5

CLN5-NCL is caused by changes in the CLN5 gene. A child inherits a changed copy of the gene from each parent (autosomal recessive).
