Long-term follow-up and novel genotype-phenotype analysis of monozygotic twins with ATP1A3 mutation in Alternating Hemiplegia of Childhood-2
2020
Alternating Hemiplegia of Childhood (AHC) is a rare disorder characterized by frequent, transient attacks of hemiplegia involving either side of the body or both in association to several other disturbances including dystonic spells, abnormal ocular movements, autonomic manifestations, epileptic seizures and cognitive impairment. The clinical manifestations usually start before the age of 18 months. Two forms of the disorder known as AHC-1 (MIM#104290) and AHC-2 (MIM#614820) depends on mutations in ATP1A2 and ATP1A3 genes respectively, with over 75% of AHC caused by a mutation in the ATP1A3 gene. Herewith, we report serial clinical follow-up data of monozygotic (MZ) twin sisters, who presen…

Additional file 1: S1. AHC diagnostic and laboratory test. Routine laboratory examination, plasma amino acids, urine organic acids, blood lactate, pyruvate, urea, ammonia, thyroid functions, arterial blood gases (ABG), EEG, Video-EEG, MRI and MRI angiography are effective to exclude metabolic disorders and vascular diseases having the same pattern of features such as homocystinuria, organic acidurias (glutaric aciduria), urea cycle disorders (ornithine transcarbamylase deficiency, carbamoyl phosphate synthetase I deficiency, and citrullinemia) and Moyamoya disease. Diagnostic check-up may also include analysis of pterins, 5-methyltetrahydrofolate (5-MTHF) and monoamine metabolites in the ce…
Alternating Hemiplegia of Childhood: neurological comorbidities and intrafamilial variability.
2022
Abstract Background Alternating of Childhood (AHC) is an uncommon and complex disorder characterized by age of onset before 18 months with recurrent hemiplegia of one or either sides of the body or quadriplegia. The disorder is mainly caused by mutations in ATP1A3 gene, and to a lesser extent in ATP1A2 gene. In AHC neurological co-morbidities are various and frequently reported including developmental delay, epilepsy, tonic or dystonic spells, nystagmus,autonomic manifestations with intrafamilial variability. Case presentation Clinical and genetic findings of a couple of twins (Family 1: Case 1 and Case 2) and a couple of siblings (Family 2: Case 3 and Case 4) coming from two different Ital…
