Is Basilar migraine inherited ?
Are basilar migraines inherited? In most cases, basilar migraines are not inherited. However, the susceptibility to basilar migraines may rarely be caused by a change (mutation) in the ATP1A2 gene or CACNA1A gene. In these cases, they are inherited in an autosomal dominant manner. This means that to be affected, a person only needs a mutation in one copy of the responsible gene in each cell. In some cases, an affected person inherits the mutation from an affected parent. Other cases may result from new (de novo) mutations in the gene. These cases occur in people with no history of the disorder in their family. A person with one of these mutations has a 50% chance with each pregnancy of passing along the altered gene to his or her child.
