[Jervell and Lange-Nielsen syndrome]
Abstract
Summary Jervell and Lange-Nielsen syndrome（JLNS） is an autosomal recessive hereditary disease characterized by congenital severe sensorineural hearing loss in both ears and severe arrhythmias with QT interval prolongation. Children with JLNS often exhibit sensorineural hearing loss and are easily misdiagnosed as non-syndromic hearing loss before attack of cardiac event. When a cochlear implant is performed, a fatal arrhythmia is likely to occur during the perioperative period, which seriously threatens the life of the child. It is currently found that the pathogenic genes of JLNS are mainly KCNQ1 and KCNE1. This article reviews the clinical manifestations, pathogenic genes, diagnosis and differential diagnosis, intervention measures of JLNS to further draw the attention to the disease, reduce misdiagnosis, improve the survival rate and quality of life of children with JLNS.
Keywords: Jervell and Lange-Nielsen syndrome; cochlear implantation; deafness; long QT syndrome.
