| Inherited white matter disorders v1.138 | EIF2AK2 | Arina Puzriakova edited their review of gene: EIF2AK2: Added comment: A further 5 families reported (PMID: 33236446) harbouring 3 different variants in this gene (including the first homozygous case). Clinical presentation was prominent in all cases for dystonia with onset in infancy or childhood, with subsequent generalisation. 3 unrelated individuals additionally developed mild ID, spasticity, and brain MRI alterations (including white matter abnormalities); while 6 individuals from the remaining 2 families had only isolated dystonia.; Changed publications to: 32197074, 33236446 | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Arina Puzriakova gene: EIF2AK2 was added gene: EIF2AK2 was added to Inherited white matter disorders. Sources: Literature Mode of inheritance for gene: EIF2AK2 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted Publications for gene: EIF2AK2 were set to 32197074 Phenotypes for gene: EIF2AK2 were set to Leukoencephalopathy, developmental delay, and episodic neurologic regression syndrome, 618877 Review for gene: EIF2AK2 was set to GREEN Added comment: Association with Developmental Delay, Leukoencephalopathy, and Neurologic Decompensation reported in both OMIM and G2P (probable). PMID: 32197074 (2020) - Distinct de novo missense variants were identified in eight unrelated individuals who all share a notable phenotypic overlap of developmental delay, cognitive impairment, white matter alterations, dysarthria or lack of speech, and neurologic regression with febrile illness. Other variable features included hypotonia (7/8), hypertonia (7/8), ataxia (6/8), dystonia (5/8), tremor (3/8) and seizures (4/8). Functional data confirm reduced kinase activity compared to the wildtype protein product, and authors predict a dominant-negative effect. Sources: Literature |
