My sister says she has basilar artery migraine. are family members more likely to get the same thing?

Could be.: This type of migraine falls under the list of 'migraine variants'. As such, it may not act like a 'typical migraine'. Patients with migraine variants can have symptoms other than headache. And yes, they can run in families. Talk to your sister and see what problems she was having that made her go to her docor. If you have had similar problems, talk to your doctor about them.
