Choose from 1 of 6 CLCN1 antibodies which have been validated in experiments with 8 images featured in our data gallery. One lineage also has coexistent R894X A313T and A320V mutations. As mentioned earlier mutations in CLCN1 cause both dominant and recessive MC.
Mutation of the human skeletal muscle sodium channel. A common phenotype of dominant mutations is a dominant negative effect of mutant subunits in mutant-WT heterodimers causing a large shift of the steady-state open probability voltage-dependence towards more posi-. The CLCN1 gene provides instructions for making a type of protein called a chloride channel.
No CLCN1 mutations were identified in two families. A gene on chromosome 7q34 that encodes a voltage-gated chloride channel that regulates the electric excitability of skeletal muscle membranes. Establishment of this gene variant database LSDB was supported by the Leiden University Medical Center LUMC Leiden Nederland.
Our data support the presence of genetic heterogeneity and additional modifying factors in myotonia congenita. The protein encoded by this gene ClC-1 is comprised of symmetric homodimers Figure 983 that produce two ion-conducting pores. Plays an important role in membrane repolarization in skeletal muscle cells after muscle contraction.
CLCN1 Chloride Voltage-Gated Channel 1 is a Protein Coding gene. THD is characterized by skeletal muscle stiffness delayed relaxation due to membrane hyperexcitability. CLCN1 mutations are spread throughout the sequence of the gene Pusch and are predicted to produce functional changes in the chloride channel protein CIC-1 with faulty assembly of subunits impaired ion channel formation and channel dysfunction Fig.
