They performed a literature review of current\u00a0<i><em>STXBP1<\/em><\/i>\u00a0research and compared the observed features in the newly-identified 45 individuals with 102 other individuals with\u00a0<i><em>STXBP1<\/em><\/i>\u00a0mutations who were previously published in other research articles.<\/p>\n<p><span style=\"font-weight: 400;\">Ranging from 6 months to 56 years in age, researchers compared diagnoses (see below) and features observed in the 147 individuals with\u00a0<i><em>STXBP1\u00a0<\/em><\/i>mutations. All 147 individuals were reported as having some degree of intellectual disability (ID), with approximately 88.4% categorized as severe or profound ID. The majority of individuals (approximately 95%) were found to have an epilepsy-related diagnosis, with onset early in life, which likely prompted genetic testing in the first place. Over 60% of those diagnosed with a form of epilepsy have a history of abnormal EEGs. Autism was observed in approximately 1 in 5 individuals and impaired or delayed motor functioning were frequently reported.<\/span><\/p>\n<table style=\"width: 100%; border: 1px solid black;\">\n<tbody>\n<tr>\n<td style=\"color: white; background-color: #f36046; text-align: center; padding: 5px; border: 1px solid #d9d9d9;\" colspan=\"2\"><strong>STXBP1-Associated Diagnoses Seen in 147 Individuals<\/strong><\/td>\n<\/tr>\n<tr>\n<td style=\"background-color: #ffbcb0; text-align: center; padding: 5px; border: 1px solid #d9d9d9;\"><strong>Diagnosis<\/strong><\/td>\n<td style=\"background-color: #ffbcb0; text-align: center; padding: 5px; border: 1px solid #d9d9d9;\"><strong>Percentage of Individuals with Diagnosis (%)<\/strong><\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 5px; border: 1px solid #d9d9d9;\"><strong>Early-onset epileptic encephalopathy (EOEE)<\/strong><\/td>\n<td style=\"text-align: center; padding: 5px; border: 1px solid #d9d9d9;\">53<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 5px; border: 1px solid #d9d9d9;\"><strong>Ohtahara Syndrome<\/strong><\/td>\n<td style=\"text-align: center; padding: 5px; border: 1px solid #d9d9d9;\">21<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 5px; border: 1px solid #d9d9d9;\"><strong>West Syndrome<\/strong><\/td>\n<td style=\"text-align: center; padding: 5px; border: 1px solid #d9d9d9;\">10<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 5px; border: 1px solid #d9d9d9;\"><strong>Intellectual Disability (ID) without epilepsy<\/strong><\/td>\n<td style=\"text-align: center; padding: 5px; border: 1px solid #d9d9d9;\">7<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 5px; border: 1px solid #d9d9d9;\"><strong>Intellectual Disability (ID) with epilepsy<\/strong><\/td>\n<td style=\"text-align: center; padding: 5px; border: 1px solid #d9d9d9;\">6<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 5px; border: 1px solid #d9d9d9;\"><strong>Dravet Syndrome<\/strong><\/td>\n<td style=\"text-align: center; padding: 5px; border: 1px solid #d9d9d9;\">2<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 5px; border: 1px solid #d9d9d9;\"><strong>Early myoclonic encephalopathy (EME)<\/strong><\/td>\n<td style=\"text-align: center; padding: 5px; border: 1px solid #d9d9d9;\">1<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>STXBP1 Encephalopathy Original research article by Stamberger et al.
