Clinical, electrophysiological, and mo-lecular genetic features were investigated in two patients from a family a with domi-nantly inherited myotonic disease, char-acterised by painful cramps, stiVness without weakness, fluctuation of symp-toms, and cold sensitivity. A reduction in amplitude of the compound muscle action potential was demonstrated on cooling and administration of potassium, alth-ough no clinical exacerbation was seen. A heterozygote mutation Val1589Met was identified in the á-subunit of the skeletal muscle sodium channel gene in both patients, consistent with the diagnosis of potassium-aggravated myotonia. The phenotype in this family is much milder than that previously described in another family with a mutation at this si...
