Summaries for Migraine, Familial Hemiplegic, 3

NIH Rare Diseases : 53 Familial hemiplegic migraine (FHM) is a form of migraine headache that runs in families. Migraines usually cause intense, throbbing pain in one area of the head, often accompanied by nausea, vomiting, and extreme sensitivity to light and sound. These recurrent headaches typically begin in childhood or adolescence and may last from a few hours to a few days. People with familial hemiplegic migraine experience an aura that comes before the headache. The most common symptoms associated with an aura are temporary visual changes such as blind spots (scotomas), flashing lights, zig-zagging lines, and double vision. In people with familial hemiplegic migraine, auras are also characterized by temporary numbness or weakness, often affecting one side of the body (hemiparesis). An aura typically develops gradually over a few minutes and lasts about an hour. Researchers have identified three forms of familial hemiplegic migraine known as FHM1, FHM2, and FHM3. Each of the three types is caused by mutations in a different gene. Treatment varies depending on signs and symptoms and may include use of anti migraine or anti seizure medications.

MalaCards based summary : Migraine, Familial Hemiplegic, 3, also known as familial hemiplegic migraine type 3, is related to familial hemiplegic migraine and migraine, familial hemiplegic, 2, and has symptoms including hemiparesis, hemiplegia and photophobia. An important gene associated with Migraine, Familial Hemiplegic, 3 is SCN1A (Sodium Voltage-Gated Channel Alpha Subunit 1). Related phenotypes are photophobia and blindness

UniProtKB/Swiss-Prot : 75 Migraine, familial hemiplegic, 3: A subtype of migraine associated with transient blindness in some families. Migraine is a disabling symptom complex of periodic headaches, usually temporal and unilateral. Headaches are often accompanied by irritability, nausea, vomiting and photophobia, preceded by constriction of the cranial arteries. The two major subtypes are common migraine (migraine without aura) and classic migraine (migraine with aura). Classic migraine is characterized by recurrent attacks of reversible neurological symptoms (aura) that precede or accompany the headache. Aura may include a combination of sensory disturbances, such as blurred vision, hallucinations, vertigo, numbness and difficulty in concentrating and speaking.
