| Abstract: | Objective: To characterize phenotypes of a novel CACNA1A mutation causing familial hemiplegic migraine type 1. Background: Familial hemiplegic migraine is a rare monogenic form of migraine associated with attacks of fully reversible unilateral motor weakness. We now report a novel CACNA1A gene mutation associated with fully reversible bilateral motor weakness (diplegia). Methods: The proband underwent genotyping which identified a novel CACNA1A missense mutation (c.622 [isoform 1] G > A [p.Gly208Arg]). To characterize phenotypes associated with this novel mutation, the proband and 8 of her similarly affected family members underwent a semi‐structured interview. Results: All 9 subjects who were interviewed met ICHD‐3 phenotypic diagnostic criteria for FHM, including reporting attacks with reversible unilateral motor weakness. Additionally, 7 of 9 subjects reported attacks including reversible motor weakness affecting both sides of the body simultaneously. Conclusions: We describe a novel CACNA1A mutation associated with migraine attacks including reversible diplegia. [ABSTRACT FROM AUTHOR] |
