Childhood onset dystonia, chorea or related movement disorder
Gene: ACER3
The rating of this gene has been updated to green and the mode of inheritance set to BIALLELIC, autosomal or pseudoautosomal following NHS Genomic Medicine Service approval.Created: 30 Jan 2023, 6:27 p.m. | Last Modified: 30 Jan 2023, 6:28 p.m.

Comment on list classification: There is enough evidence to rate this gene Green on this panel at the next GMS review - now at least 5 unrelated families reported with homozygous variants (PMIDs: 26792856; 32816236; 34281620). Phenotypes that are consistent amongst all affected individuals comprise of developmental regression (motor and cognitive), dystonia, spasticity, and leukodystrophy.Created: 25 Mar 2022, 12:18 p.m. | Last Modified: 25 Mar 2022, 12:18 p.m.

Additional publication (Dehvani et al., 2021; PMID: 34281620) detailing three further unrelated cases, each with novel homozygous variants in the ACER3 gene. All individuals displayed features of progressive leukoencephalopathy, developmental delay, hypotonia, appendicular spasticity, and dystonia. Early development is apparently normal followed by symptoms of stagnation and neurologic regression (onset within first year of life).Created: 25 Mar 2022, 12:11 p.m. | Last Modified: 25 Mar 2022, 12:11 p.m.

Comment on list classification: New gene added by Zornitza Stark (Australian Genomics). This gene is associated with a relevant phenotype in OMIM but not in Gene2Phenotype. Currently, there is not enough evidence to support a gene-disease association. This gene has been given an Amber rating.Created: 13 May 2021, 12:16 p.m. | Last Modified: 13 May 2021, 12:16 p.m.
