Early onset or syndromic epilepsy v2.601 ADAR Arina Puzriakova Phenotypes for gene: ADAR were changed from Aicardi-Goutieres syndrome 6 615010 to Aicardi-Goutieres syndrome 6, OMIM:615010
Early onset or syndromic epilepsy v2.491 ADARB1 Sarah Leigh Tag for-review was removed from gene: ADARB1.
Early onset or syndromic epilepsy v2.491 ADARB1 Sarah Leigh commented on gene: ADARB1: The rating of this gene has been updated following NHS Genomic Medicine Service approval.
Early onset or syndromic epilepsy v2.490 ADARB1 Sarah Leigh Source Expert Review Green was added to ADARB1.
Rating Changed from Amber List (moderate evidence) to Green List (high evidence)
Early onset or syndromic epilepsy v2.147 ADARB1 Arina Puzriakova Publications for gene: ADARB1 were set to 32220291
Early onset or syndromic epilepsy v2.146 ADARB1 Arina Puzriakova edited their review of gene: ADARB1: Added comment: PMID: 32719099 (2020) - Three additional patients from two consanguineous families with novel biallelic variants in the ADARB1 gene. All affected individuals presented global DD, severe-profound ID, intractable early infantile-onset seizures, severe microcephaly, axial hypotonia and progressive appendicular spasticity. In vitro RNA editing assays showed that both variants resulted in severe impairment or loss of ADAR2 enzymatic activity.; Changed publications: 32220291, 32719099
Early onset or syndromic epilepsy v2.122 ADARB1 Arina Puzriakova changed review comment from: Variants reported in four unrelated individuals with severe/profound intellectual disability, microcephaly, and seizures, which were intractable in three of the individuals. Functional studies demonstrate variants result in reduction of ADARB1 product activity or changes in splicing (PMID: 32220291). Homozygous knockout mice presented with seizures and early death, supporting the role of ADARB1 in brain function (PMID: 10894545)

Gene is associated with phenotype in OMIM and G2P.

PMID: 32220291 - Bi-allelic variants reported in four unrelated individuals with severe/profound intellectual disability, microcephaly, and seizures. Functional studies demonstrate variants result in reduction in ADARB1 product activity or changes in splicing.
PMID: 10894545 - Homozygous knockout mice presented with siezures and early death, supporting the role of ADARB1 in brain function
