Inherited white matter disorders v1.129 ACOX1 Ivone Leong changed review comment from: Comment on mode of inheritance: PMID: 32169171. 3 unrelated patients with the same de novo variant (N237S) with a progressive disease. Age of onset is between 3-12 years old (cf to AR patients 0-3 years old), disease course is progressive (AR patients, early onset and severe) white matter demyelination is progressive, sensorineural hearing loss and ataxia. Authors found that the variant increased levels of ACOX1 protein and function which increased levels of ROS in glia of Drosphila and mouse Schwann cells leading to glial degeneration. The authors suggested that the variant caused a GOF effect. Therefore, MOI should be changed from Biallelic to Both monoallelic and biallelic (but biallelic mutations cuase a more severe disease form).; to: Comment on mode of inheritance: PMID: 32169171. 3 unrelated patients with the same de novo variant (N237S) with a progressive disease.

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.
