Familial cramps and muscle pain
R. P. Lazaro, R. D. Rollinson and G. M. Fenichel
A family with a disorder characterized by muscle cramps that cause painful
posturing of the hands and feet was studied. Three generations are affected
and the trait is transmitted by autosomal dominant inheritance. The
disorder begins in childhood and does not seem to be progressive. A primary
abnormality in the motor neuron is suspected on the basis of
electrophysiological studies.
