В большинстве случаев данная патология характеризуется развитием полиморфных фармакорезистентных эпилептических приступов в первый год жизни ребёнка, отставанием в психомоторном развитии или регрессом, потерей навыков. У некоторых пациентов приступы могут проявляться в первые дни жизни, тогда как у других они проявляются позже (в возрасте от 2 до 7 мес), на фоне выраженной или незначительной задержки развития. Типы приступов могут включать генерализованные, тонико-клонические приступы, инфантильные спазмы, абсансы и фокальные приступы. Другие признаки и симптомы энцефалопатии, обусловленной мутациями гена SCN8A, могут включать низкий мышечный тонус (гипотонию), высокий болевой порог, двигательные расстройства (такие как дистония и атаксия), умственную отсталость от лёгкой до тяжёлой степени, проблемы со сном и аутистические черты. У некоторых людей с энцефалопатией SCN8A сообщалось о различных других патологических изменениях в организме, включая нарушение слуха или зрения, сколиоз и трудности терморегуляции. Болезнь наследуется по аутосомно-доминантному типу.</p><p>На сегодняшний день заболевание в системе OMIM именуется как «Энцефалопатия развития и эпилептическая энцефалопатия 13-го типа». Прежде болезнь носила название «Ранняя младенческая (инфантильная) эпилептическая энцефалопатия, тип 13». Порядковый номер «13» указывает на то, что данная форма ранней эпилептической энцефалопатии вызвана гетерозиготной мутацией в гене SCN8A на длинном плече хромосомы 12 в хромосомной области 12q13.13.</p><p>В данной публикации представлено также клиническое описание пациента, страдающего ранней инфантильной эпилептической энцефалопатией, тип 13.</p><sec><title>Финансирование</title><p>Финансирование.

In most cases, this pathology is characterized by the development of polymorphic pharmacoresistant epileptic seizures over the first year of a child’s life, a lag in psychomotor development or regression, loss of skills. In some patients, seizures may appear during the first days of life, while in others they appear later (at the age of 2 to 7 months), against the background of a pronounced or slight developmental delay. Types of seizures may include generalized, tonic-clonic seizures, infantile spasms, absences and focal seizures. Other signs and symptoms of encephalopathy caused by mutations of the SCN8A gene may include low muscle tone (hypotension), high pain threshold, motor disorders (such as dystonia and ataxia), mild to severe mental retardation, sleep problems and autistic traits. In some people with SCN8A encephalopathy, various other pathological changes in the body have been reported, including hearing or vision impairment, scoliosis, and thermoregulation difficulties. The disease is inherited by an autosomal dominant type.</p><p>To date, the disease in the OMIM system is referred to as «Developmental encephalopathy and epileptic encephalopathy type 13». Previously, the disease was called «Early infantile (infantile) epileptic encephalopathy, type 13». The serial number «13» indicates this form of early epileptic encephalopathy to be caused by a heterozygous mutation in the gene on the long arm of chromosome 12 in chromosome region 12q13.13.</p><p>This report also presents a clinical description of a patient suffering from early infantile epileptic encephalopathy, type 13.</p><sec><title>Contribution</title><p>Contribution:Nikolenko D.S. — concept, text writing, text editing;Zholudova A.A. — concept, text writing, text editing;Globa O.V. — concept, text writing, text editing;Kuzenkova L.M. — concept, text editing;Savost’yanov K.V. — concept, text editing;Buksh A.A. — concept.All co-authors are responsible for the integrity of all parts of the manuscript and approval of its final version.</p></sec><sec><title>Conflict of interest</title><p>Conflict of interest.
