Popis: Channelopathies are a heterogeneous group of genetic diseases in which a defective ion channel is responsible for the symptoms. They manifest as diseases of the heart, brain or skeletal muscle. Hereditary skeletal-muscle channelopathies are characterised by myotonia, periodic paralysis or a combination of both and can be categorised as chloride, sodium and calcium channelopathies. When there is myotonia, the skeletal-muscle membrane is overexcited. In cases of periodic paralysis, the skeletal-muscle membrane is inactive. It is difficult to classify hereditary muscle channelopathies on the basis of clinical criteria only. A more reliable diagnosis is made using DNA analysis. Scientific research should focus on genotype-phenotype relationships.
