Mutations of the skeletal muscle voltage-gated sodium channel (NaV1.4) are an established cause of several clinically distinct forms of periodic paralysis and myotonia. Focal paresis has sometimes already been described. We report a case with atypical clinical manifestation comprising paramyotonia and cold-induced persistent and focal paralysis.

Leaky Channels make weak muscles

Leaky channels make weak muscles: Mutations in the skeletal muscle voltage-gated calcium channel (CaV 1.1) have been associated with hypokalemic periodic paralysis, but how these mutations cause the symptoms of the disorder has always been unclear. In this article the authors describe how they used mice with the CaV 1.1 mutation  to investigate how the mutation causes the features of HypoKPP.

Did Elizabeth Barrett Browning have Hypokalemic Periodic Paralysis?

Penn State researcher counts the ways poetess Browning may have had rare disease
By Tom Avril; Philadephia Inquirer Staff Writer

Scholars have proposed a number of explanations for the muscle weakness and other ailments that plagued the Victorian poet Elizabeth Barrett Browning. But none of these after-the-fact diagnoses - from anxiety to tuberculosis - seemed to fit the symptoms perfectly. Now Pennsylvania State University researcher Anne Buchanan thinks she has cracked the case, as the result of an intensely personal connection.
