Variability of familial hemiplegic migraine with novel A1A2 Na+/K+-ATPase variants.
نویسندگان
چکیده
A1A2 Na+/K+-ATPase mutations cause familial hemiplegic migraine type 2 (FHM2). The authors identified three putative A1A2 mutations (D718N, R763H, P979L) and three that await validation (P796R, E902K, X1021R). Ten to 20% of FHM cases may be FHM2. A1A2 mutations have a penetrance of about 87%. D718N causes frequent, long-lasting HM, and P979L may cause recurrent coma. D718N and P979L may predispose to seizures and mental retardation. A1A2 does not play a major role in sporadic HM; only one variant, R383H, occurred in 1 of 24 cases.

Rare missense variants in ATP1A2 in families with clustering of common forms of migraine.
Migraine is a recurrent neurovascular disease. Its two most common forms-migraine without aura (MO) and migraine with aura (MA)-both show familial clustering and a complex pattern of inheritance. Familial hemiplegic migraine (FHM) is a rare monogenic subform caused by mutations in the calcium channel gene CACNA1A or the Na(+)/K(+)-ATPase gene ATP1A2. An involvement of FHM genes in the pathogene...

The neurological disorder familial hemiplegic migraine type II (FHM2) is caused by mutations in the α2-isoform of the Na(+),K(+)-ATPase. We have studied the partial reaction steps of the Na(+),K(+)-pump cycle in nine FHM2 mutants retaining overall activity at a level still compatible with cell growth. Although it is believed that the pathophysiology of FHM2 results from reduced extracellular K(...
متن کاملMigraine genetics: Part II.
Migraine clusters in families and is considered to be a strongly heritable disorder. Hemiplegic migraine is a rare subtype of migraine with aura that may occur as a familial or a sporadic condition. Three genes have been identified studying families with familial hemiplegic migraine (FHM). The first FHM gene that was identified is CACNA1A. A second gene, FHM2, has been mapped to chromosome 1 q ...
متن کاملThe structure of the Na+,K+-ATPase and mapping of isoform differences and disease-related mutations.
The Na+,K+-ATPase transforms the energy of ATP to the maintenance of steep electrochemical gradients for sodium and potassium across the plasma membrane. This activity is tissue specific, in particular due to variations in the expressions of the alpha subunit isoforms one through four. Several mutations in alpha2 and 3 have been identified that link the specific function of the Na+,K+-ATPase to...

Familial hemiplegic migraine type 2 (FHM2) is an autosomal dominant form of migraine with aura that is caused by mutations of the α2-subunit of the Na,K-ATPase, an isoform almost exclusively expressed in astrocytes in the adult brain. We generated the first FHM2 knock-in mouse model carrying the human W887R mutation in the Atp1a2 orthologous gene. Homozygous Atp1a2(R887/R887) mutants died just ...
