The prevalence of epilepsy with 17p13.1\u20132 microdeletion is low, with only one case reported for late\u2010onset spasms. Late\u2010onset spasms is one of the rare epilepsy syndromes and one of the developmental epileptic encephalopathies requiring urgent treatment. We experienced two cases of 17p13.1\u20102 microdeletion syndrome, one of which presented with epileptic spasms in cluster at 18 months of age. EEG showed symmetrical hypsarrhythmia during interictal periods and a paroxysmal fast wave superimposed on widespread slow waves during seizures, leading to the diagnosis of late\u2010onset spasms. Another case had no epilepsy. Comparing the extent of deletion in the two cases with that of previous reports, the involvement of the <jats:italic>USP6<\/jats:italic> gene was suspected. However, the accumulation of additional case reports is needed to confirm the genetic involvement in late\u2010onset spasms.<\/jats:p>","DOI":"10.1684\/epd.2022.1416","type":"journal-article","created":{"date-parts":[[2022,6,1]],"date-time":"2022-06-01T15:07:56Z","timestamp":1654096076000},"page":"567-571","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Possible
