, paramyotonia congenita [MIM*168300]
a nonprogressive myotonia induced by exposure of muscles to cold; there are episodes of intermittent flaccid paralysis, but no atrophy or hypertrophy of muscles; autosomal dominant inheritance caused by mutation in the sodium channel gene (SCN4A) on chromosome 17q. This is a disorder allelic to hyperkalemic periodic paralysis. There is a variant autosomal dominant form [MIM*168350] in which cold is not a provoking factor.
