It aligns with characteristics demonstrating supporting pathogenicity (PS1) as CACNA1A is associated with autosomal dominant Developmental and epileptic encephalopathy (OMIM: 617106), Episodic ataxia (OMIM: 108500), Migraine, familial hemiplegic with progressive cerebellar ataxia (OMIM: 141500), Spinocerebellar ataxia (OMIM: 183086) and Lennox–Gastaut syndrome (OMIM: 615369); (PS2) as the mother has one of the variants and the father has the other variant; its low frequency in control databases (PS4), and moderate evidence of pathogenicity (PM4) based on the conservation of the nucleotide. The gene discussed is CACNA1A; the disease is Familial paroxysmal ataxia.
