Research is still ongoing searching for an additional gene(s) involved. This genetic mutation is now included in rare epilepsy genetic panels, no doubt leading to more individuals being correctly diagnosed.Currently around one hundred different ATP1A3 mutations are reported to cause AHC: some of them are more frequent (D801N and E815K), some others are single-case mutations. #AHCAwareness #RareDisease, Official account of Alternating Hemiplegia of Childhood UK The clinical reference centres provide opportunities for a correct and early diagnosis as well as continuous follow-up treatment and family support. Alternating hemiplegia of childhood . [1] A groundbreaking discovery in 2012 highlighted that the ATP1A3 gene causes approximately 70-80% of cases. Common triggers include excitement, fatigue, temperature change, water, pain, constipation, fever or illness, sunlight …… Many attacks, however, appear without a specific trigger and are totally unpredictable.The live of families living with AHC is unpredictable. Additional episodic symptoms usually include intermittent abnormal eye movements, episodes of muscle stiffness or posturing (dystonia), and in a substantial percentage of cases, seizures. The multispecialty team should provide regular follow-up visits, including: They should also coordinate and support any other involved local service: rehabilitation, education, and schooling, social and home assistance, psychologic support,  emergency services for the treatment of prolonged dystonic/plegic attacks and seizures/episodes of status epilepticus …. Furthermore, the OBSERV-AHC Study is investigating the natural history of AHC, the efficacy of current therapies, as well as validating some new specific scales to use as indicators for future clinical trials.

Indeed, there is an expanding spectrum of ATP1A3 neurological diseases, with overlapping symptoms:  rapid-onset dystonia-parkinsonism (RDP, DYT12, OMIM #128235), CAPOS Syndrome (OMIM #601338) and more recently, early infantile epilepsy with encephalopathy (EIEE), recurrent encephalopathy with cerebellar ataxia (RECA), Fever-Induced Paroxysmal Weakness and Encephalopathy (FIPWE), and D-DEMØ. Alternating Hemiplegia is characterised by onset in infancy or childhood of episodes of weakness of one side of the body; later in the course of the disease, both sides may be affected at the same time. Since then, research studies into AHC genotype-phenotype correlations, cardiac disturbances, secondary genes for AHC, and testing candidate compounds for AHC treatment (using in-vitro and in-vivo models) have been initiated. [4, 5] There are about one hundred AHC-causing mutations discovered so far in the ATP1A3 gene, some more frequent than others. Connect with them and share experiences.
