• Samii et al . and Scharwey and Samii described a patient who had superior oblique myokymia for 17 years.
• Myokymia is commonly used to describe an involuntary eyelid muscle contraction, typically involving the lower eyelid or less often the upper eyelid.
• Superior oblique myokymia is an uncommon neurological condition caused by vascular compression of the trochlear nerve resulting in repeated, brief, involuntary episodes of movement of the eye.
• In contrast, facial myokymia is a fine rippling of muscles on one side of the face and may reflect an underlying tumor in the brainstem ( typically a brainstem glioma ), loss of myelin in the brainstem ( associated with multiple sclerosis ) or in the recovery stage of Guillain Barr?syndrome, an inflammatory polyneuropathy that may affect the facial nerve.
• Other disorders that may be accompanied by chorea include abetalipoproteinemia, ataxia-telangiectasia, biotin-thiamine-responsive basal ganglia disease, Fahr disease, familial dyskinesia-facial myokymia ( Bird-Raskind syndrome ) due to an ADCY5 gene mutation, glutaric aciduria, Lesch-Nyhan syndrome, mitochondrial disorders, Wilson disease, hyperthyroidism, lupus erythematosus, pregnancy ( chorea gravidarum ), and side effects of certain anticonvulsants or psychotropic agents.
• The recommended name for this protein is potassium voltage-gated channel subfamily A member 1 but a number of alternatives have been used in the literature including HuK1 ( human K + channel I ), RBK1 ( rubidium potassium channel 1 ), MBK ( mouse brain K + channel ), voltage gated potassium channel HBK1, voltage gated potassium channel subunit K v 1.1, voltage-gated K + channel HuKI and AEMK ( associated with myokymia with periodic ataxia ).
