Skipping of Exon 1 in the KCNQ1 gene causes Jervell and Lange-Nielsen syndrome.
The Jervell and Lange-Nielsen syndrome (JLNS) is a rare autosomal recessive form of the long QT syndrome linked with a profound hearing loss caused by mutations affecting both alleles of either the KCNQ1 or the KCNE1 gene. We carried out a mutant screening of the KCNQ1 and KCNE1 genes in a clinical diagnosed German family with JLNS. Family members were examined by single strand conformation pol...
متن کاملNovel frameshift mutation in the KCNQ1 gene responsible for Jervell and Lange-Nielsen syndrome
Objective(s): Jervell and Lange–Nielsen syndrome is an autosomal recessive disorder caused by mutations in KCNQ1 or KCNE1 genes. The disease is characterized by sensorineural hearing loss and long QT syndrome. Methods: Here we present a 3.5-year-old female patient, an offspring of consanguineous marriage, who had a history of recurrent syncope and congenital sensorineural deafness. The patient ...
متن کاملJervell and Lange-Nielsen syndrome with homozygous missense mutation of the KCNQ1 gene.
Jervell and Lange-Nielsen syndrome (JLNS) is an autosomal recessive cardioauditory ion channel disorder characterized by congenital bilateral sensorineural deafness and long QT interval. JLNS is a ventricular repolarization abnormality and is caused by mutations in the KCNQ1 or KCNE1 gene. It has a high mortality rate in childhood due to ventricular tachyarrhythmias, episodes of torsade de poin...

متن کاملTargeted disruption of the Kcnq1 gene produces a mouse model of Jervell and Lange-Nielsen Syndrome.
KCNQ1 encodes KCNQ1, which belongs to a family of voltage-dependent K(+) ion channel proteins. KCNQ1 associates with a regulatory subunit, KCNE1, to produce the cardiac repolarizing current, I(Ks). Loss-of-function mutations in the human KCNQ1 gene have been linked to Jervell and Lange-Nielsen Syndrome (JLNS), a disorder characterized by profound bilateral deafness and a cardiac phenotype. To g...
