Intellectual disability - microarray and sequencing v3.1749 ADAR Arina Puzriakova Phenotypes for gene: ADAR were changed from Dyschromatosis symmetrica hereditaria, 127400Aicardi-Goutieres syndrome 6, 615010; DYSCHROMATOSIS SYMMETRICA HEREDITARIA 1 to Aicardi-Goutieres syndrome 6, OMIM:615010; Dyschromatosis symmetrica hereditaria, OMIM:127400
Intellectual disability - microarray and sequencing v3.1748 ADAR Arina Puzriakova reviewed gene: ADAR: Rating: ; Mode of pathogenicity: None; Publications: 16225627, 16817193, 19017046; Phenotypes: Aicardi-Goutieres syndrome 6, OMIM:615010, Dyschromatosis symmetrica hereditaria, OMIM:127400; Mode of inheritance: BOTH monoallelic and biallelic, autosomal or pseudoautosomal
Intellectual disability - microarray and sequencing v3.1746 ADAR Tracy Lester reviewed gene: ADAR: Rating: GREEN; Mode of pathogenicity: None; Publications: ; Phenotypes: Intellectual disability, developmental delay, delayed speech and language, learning disability; Mode of inheritance: BIALLELIC, autosomal or pseudoautosomal
Intellectual disability - microarray and sequencing v3.1511 ADARB1 Arina Puzriakova Tag for-review was removed from gene: ADARB1.
Intellectual disability - microarray and sequencing v3.1510 ADARB1 Sarah Leigh commented on gene: ADARB1: The rating of this gene has been updated following NHS Genomic Medicine Service approval.
Intellectual disability - microarray and sequencing v3.1509 ADARB1 Arina Puzriakova Source Expert Review Green was added to ADARB1.
Rating Changed from Amber List (moderate evidence) to Green List (high evidence)
Intellectual disability - microarray and sequencing v3.276 ADARB1 Arina Puzriakova Publications for gene: ADARB1 were set to 32220291
Intellectual disability - microarray and sequencing v3.275 ADARB1 Arina Puzriakova Phenotypes for gene: ADARB1 were changed from Intellectual disability; microcephaly; seizures to Neurodevelopmental disorder with hypotonia, microcephaly, and seizures, 618862
Intellectual disability - microarray and sequencing v3.274 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
Intellectual disability - microarray and sequencing v3.170 ADARB1 Arina Puzriakova changed review comment from: Variants reported in four unrelated individuals with severe/profound intellectual disability, microcephaly, and seizures. 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.; to: 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.

This gene has also been added to the Genetic Epilepsy and Severe Microcephaly panels with a suggested Green classification at the next major review.
