Zornitza Stark gene: RHOBTB2 was added gene: RHOBTB2 was added to Alternating Hemiplegia and Hemiplegic Migraine. Sources: Literature Mode of inheritance for gene: RHOBTB2 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted Publications for gene: RHOBTB2 were set to 33504645 Phenotypes for gene: RHOBTB2 were set to Developmental and epileptic encephalopathy 64 618004; Alternating hemiplegia Review for gene: RHOBTB2 was set to GREEN Added comment: Eleven affected patients were identified. All had heterozygous missense variants involving exon 9 of RHOBTB2, confirmed as de novo in 9 cases. All had a complex motor phenotype, including at least 2 different kinds of movement disorder, e.g., ataxia and dystonia. Many patients demonstrated several features fulfilling the criteria for AHC: 10 patients had a movement disorder including paroxysmal elements, and 8 experienced hemiplegic episodes. In contrast to classic AHC, commonly caused by mutations in ATP1A3, these events were reported later only in RHOBTB2 mutation-positive patients from 20 months of age. All had ID, and many had seizures, so this represents an expansion of the phenotype rather than a distinct disorder. Sources: Literature |
