Genomic nucleic acid was extracted, and a complete coding sequence of the human genome (whole-exome sequencing) was sequenced. Moreover, Sanger sequencing of variants of interest was performed to validate the exome-discovered variants.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We identified a heterozygous pathogenic missense mutation (c.1498C&amp;gt;T; p.Arg500Trp) in the <jats:italic>SCN1A<\/jats:italic> gene in the patient using the whole-exome sequencing approach. The onset of PD features in our patient occurred at the age of 30 years. Biochemical investigations were carried out to rule out any secondary cause of the disease, including Wilson's disease or another metabolic disorder. MRI of the brain and spinal images were unremarkable. Moreover, a dramatic response to carbidopa\u2013levodopa treatment was also observed in the patient.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Our results suggest that the pathogenic variant in <jats:italic>SCN1A<\/jats:italic> may lead to PD features without epilepsy.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fgene.2024.1496683","type":"journal-article","created":{"date-parts":[[2024,11,6]],"date-time":"2024-11-06T06:12:29Z","timestamp":1730873549000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["De novo SCN1A missense variant in a patient with Parkinson\u2019s disease"],"prefix":"10.3389","volume":"15","author":[{"given":"Majed","family":"Alluqmani","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abdulfatah M.","family":"Alayoubi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jamil A.","family":"Hashmi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sulman","family":"Basit","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2024,11,6]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"2175","DOI":"10.1002\/mds.22589","article-title":"Neuropsychiatric symptoms in Parkinson\u2019s disease","volume":"24","author":"Aarsland","year":"2009","journal-title":"Mov.
