LD is an ultra\u2010rare, autosomal recessive, severe form of progressive myoclonus epilepsy affecting previously healthy children or adolescents. In both patients, the presence of developmental delay, intellectual disability, and behavioral abnormalities was consistent with a primary genetic disorder\u2014\n                      <jats:italic>TRIO<\/jats:italic>\n                      \u2010related neurodevelopmental disorder in one, and Phelan\u2010McDermid syndrome in the other. However, the onset of epilepsy with atypical features, coupled with progressive neurological decline in one patient and a positive family history of LD in the other, prompted the additional diagnosis of LD. These cases illustrate how overlapping clinical presentations can obscure the presence of concomitant genetic conditions, potentially delaying diagnosis and appropriate management. Our findings underscore the importance of considering dual diagnoses and show that phenotypical variability in ultra\u2010rare disorders such as LD may be influenced by concurrent genetic conditions.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Plain Language Summary<\/jats:title>\n                    <jats:p>This report describes two patients who have both Lafora disease, an ultra\u2010rare, progressive type of epilepsy, and other rare genetic disorders that affect development and behavior. In one case, the patient showed a progressive and unusual neurological deterioration, while the other had atypical epileptic seizures and a family history of Lafora disease. These cases highlight how different genetic conditions can share similar symptoms, making it difficult to identify all the issues a patient may have. Understanding these overlaps is important for proper diagnosis and treatment.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/epi4.70104","type":"journal-article","created":{"date-parts":[[2025,9,26]],"date-time":"2025-09-26T14:39:48Z","timestamp":1758897588000},"page":"1990-1996","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The challenge of ultra\u2010rarity: Dual diagnosis of Lafora disease and developmental encephalopathies linked to\n                    <i>TRIO<\/i>\n                    and\n                    <i>SHANK3<\/i>\n                    pathogenic variants"],"prefix":"10.1002","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6827-0099","authenticated-orcid":false,"given":"Lorenzo","family":"Muccioli","sequence":"first","affiliation":[{"name":"IRCCS Istituto delle Scienze Neurologiche di Bologna (Full Member of the ERN EpiCARE)  Bologna Italy"},{"name":"Department of Biomedical and Neuromotor Sciences University of Bologna  Bologna Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1109-7296","authenticated-orcid":false,"given":"Francesca","family":"Bisulli","sequence":"additional","affiliation":[{"name":"IRCCS Istituto delle Scienze Neurologiche di Bologna (Full Member of the ERN EpiCARE)  Bologna Italy"},{"name":"Department of Biomedical and Neuromotor Sciences University of Bologna  Bologna Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Raffaella","family":"Minardi","sequence":"additional","affiliation":[{"name":"IRCCS Istituto delle Scienze Neurologiche di Bologna (Full Member of the ERN EpiCARE)  Bologna Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria Lucia","family":"Valentino","sequence":"additional","affiliation":[{"name":"IRCCS Istituto delle Scienze Neurologiche di Bologna (Full Member of the ERN EpiCARE)  Bologna Italy"},{"name":"Department of Biomedical and Neuromotor Sciences University of Bologna  Bologna Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Micaela","family":"De Simone","sequence":"additional","affiliation":[{"name":"Center for Research on Epilepsy in Pediatric Age (CREP) and Child Neuropsychiatry Unit University Hospital of Verona (Full Member of the ERN EpiCARE)  Verona Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rodrigo Almeida","family":"Paroni","sequence":"additional","affiliation":[{"name":"Center for Research on Epilepsy in Pediatric Age (CREP) and Child Neuropsychiatry Unit University Hospital of Verona (Full Member of the ERN EpiCARE)  Verona Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Edward","family":"Cesnik","sequence":"additional","affiliation":[{"name":"Neurology Unit University Hospital of Ferrara  Ferrara Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elisa","family":"Fallica","sequence":"additional","affiliation":[{"name":"Neurology Unit University Hospital of Ferrara  Ferrara Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luigi","family":"Bonan","sequence":"additional","affiliation":[{"name":"Department of Biomedical and Neuromotor Sciences University of Bologna  Bologna Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4342-0772","authenticated-orcid":false,"given":"Eleonora","family":"Pizzi","sequence":"additional","affiliation":[{"name":"IRCCS Istituto delle Scienze Neurologiche di Bologna (Full Member of the ERN EpiCARE)  Bologna Italy"},{"name":"Department of Biomedical and Neuromotor Sciences University of Bologna  Bologna Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"DEFEAT\u2010LD Study Group","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gaetano","family":"Cantalupo","sequence":"additional","affiliation":[{"name":"Center for Research on Epilepsy in Pediatric Age (CREP) and Child Neuropsychiatry Unit University Hospital of Verona (Full Member of the ERN EpiCARE)  Verona Italy"},{"name":"Innovation Biomedicine Section, Department of Engineering for Innovation Medicine University of Verona  Verona Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7979-9895","authenticated-orcid":false,"given":"Laura","family":"Licchetta","sequence":"additional","affiliation":[{"name":"IRCCS Istituto delle Scienze Neurologiche di Bologna (Full Member of the ERN EpiCARE)  Bologna Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,9,26]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41582\u2010018\u20100057\u20100"},{"key":"e_1_2_11_3_1","unstructured":"https:\/\/www.orpha.net\/en\/disease\/detail\/501?name=lafora%20disease&mode=name;
