De novo SCN1A géndeletio terápiarezisztens Dravet-szindrómában

Abstract: A Dravet-szindróma vagy régebbi nevén súlyos csecsemőkori myoclonusos epilepszia igen ritka formája az epilepsziának. Az autoszomális domináns öröklésmenetet mutató kórkép leggyakoribb oka a feszültségfüggő nátriumcsatorna alfa-1 alegységet kódoló SCN1A gén mutációja. Az esetek többségének hátterében de novo pontmutáció áll, azonban néhány betegben a gén kópiaszám-változása fi gyelhető meg. Az SCN1A gén által kódolt fehérje a neuronalis ingerü-let kiváltásában és vezetésében játszik szerepet. A génmutációk töb… Show more

“…The frequency of MLPA-detected anomalies were 9,09% in our cohort which is similar to that published in the study of Marini et al (2009) [32,33]. Based on literature data, the average frequency of MLPA-detected deletions and duplications is approximately 10-12% among SCN1A-mutation negative patients; therefore we recommend this method as a second-tier of screening [34]. Our patients with confirmed gross deletions of SCN1A do not show any phenotypic difference compared to those with point mutations: febrile and/or afebrile seizures and intellectual disability remain the characteristic features in both groups.…”
