Short summary

Hypothesized to cause familial hemiplagic migraine type 2 in a dominant manner, which causes migraine with associated motor weakness as well as aura. This variant was reported seen in only one family; not enough evidence has been reported to establish a statistically significant association with the disease.

Variant evidence
Computational 2

Polyphen 2 predicts damaging effect, other variants in this gene implicated in this disease

Functional -
Case/Control -
Familial 1

Seen in one family, genotype segregating with phenotype in four children tested (includes proband; estimated LOD: 0.9)

See Tonelli A et al. 2007 (17877748).

Clinical importance
