| Disease ID | Source | Name | Description |
| 108500 | OMIM | Episodic ataxia 2 (EA2) | An autosomal dominant disorder characterized by acetozolamide-responsive attacks of ataxia, migraine-like symptoms, interictal nystagmus, and cerebellar atrophy. The disease is caused by variants affecting the gene represented in this entry. |
| 141500 | OMIM | Migraine, familial hemiplegic, 1 (FHM1) | A subtype of migraine with aura associated with ictal hemiparesis and, in some families, cerebellar ataxia and atrophy. Migraine is a disabling symptom complex of periodic headaches, usually temporal and unilateral. Headaches are often accompanied by irritability, nausea, vomiting and photophobia, preceded by constriction of the cranial arteries. Migraine with aura is characterized by recurrent attacks of reversible neurological symptoms (aura) that precede or accompany the headache. Aura may include a combination of sensory disturbances, such as blurred vision, hallucinations, vertigo, numbness and difficulty in concentrating and speaking. The disease is caused by variants affecting the gene represented in this entry. |
| 183086 | OMIM | Spinocerebellar ataxia 6 (SCA6) | Spinocerebellar ataxia is a clinically and genetically heterogeneous group of cerebellar disorders. Patients show progressive incoordination of gait and often poor coordination of hands, speech and eye movements, due to degeneration of the cerebellum with variable involvement of the brainstem and spinal cord. SCA6 is an autosomal dominant cerebellar ataxia (ADCA), mainly caused by expansion of a CAG repeat in the coding region of CACNA1A. There seems to be a correlation between the repeat number and earlier onset of the disorder. The disease is caused by variants affecting the gene represented in this entry. |
| 617106 | OMIM | Developmental and epileptic encephalopathy 42 (DEE42) | A form of epileptic encephalopathy, a heterogeneous group of severe childhood onset epilepsies characterized by refractory seizures, neurodevelopmental impairment, and poor prognosis. Development is normal prior to seizure onset, after which cognitive and motor delays become apparent. DEE42 inheritance is autosomal dominant. The disease is caused by variants affecting the gene represented in this entry. |
