After the parents told the story of their daughter and the long diagnostic odyssey, the clinicians reviewed the complex symptomatology that has been reported to accompany pathogenic variants in CACNA1A. Termed CACNA1A-related disorders, (CRD), these include three different autosomal dominantly inherited neurological conditions: Familial Hemiplegic Migraine, type 1 (FHM1), Episodic Ataxia, type 2 (EA-2), and Spino-Cerebellar Ataxia, type 6 (SCA6)[5, 6]. The gene discussed is CACNA1A; the disease is Familial paroxysmal ataxia.
