ATP1A2 is also associated with other autosomal dominant entities such as alternating hemiplegia of childhood 1 (AHC1, OMIM 104290), developmental and epileptic encephalopathy 98 (DEE98, OMIM 619605), and fetal akinesia, respiratory insufficiency, microcephaly, polymicrogyria, and dysmorphic facies (FARIMPD, OMIM 619602). This evidence concerns the gene ATP1A2 and alternating hemiplegia of childhood.
