Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Lafora Disease Patients

Documented genetic diagnosis of Lafora disease; clinical diagnosis of Lafora disease and a sibling with a known mutation in EPM2A or EPM2B; clinical diagnosis of Lafora disease and a previously undescribed mutation in EPM2A or EPM2B; asymptomatic siblings if mutation positive prior to enrollment.

No interventions assigned to this group

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Documented genetic diagnosis of Lafora disease based on mutations in both alleles of either the EPM2A or the EPM2B gene and a sibling with a known mutation in EPM2A or EPM2B.
2. Able and willing to comply with the study protocol, including travel to Study Center, procedures, measurements and visits, including:

1. Adequately supportive psychosocial circumstances, in the opinion of the Investigator
2. Caregiver/trial partner committed to facilitate patient's involvement in the study who is reliable, competent, at least 18 years of age.
3. Adequate visual and auditory acuity for neuropsychological testing

Exclusion Criteria

1. Any known genetic abnormality, including chromosomal aberrations that confound the clinical phenotype
2. Subjects with:

1. complete absence of speech OR
2. inability to perform any activities of daily living OR
3. who are completely bedridden.
3. Current participation in an interventional or therapeutic study
4. Receiving an investigational drug within 90 days of the Baseline Visit
5. Prior or current treatment with gene or stem cell therapy
6. Any other diseases which may significantly interfere with the assessment of Lafora disease.
7. Have any other conditions, which, in the opinion of the Investigator or Sponsor would make the subject unsuitable for inclusion, or could interfere with the subject participating in or completing the study.
