| Severe microcephaly v2.19 | 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 | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Severe microcephaly v2.11 | ADARB1 |
Arina Puzriakova changed review comment from: Variants reported in four unrelated individuals with severe/profound intellectual disability, microcephaly, and seizures. Affected individuals were microcephalic at birth or developed postnatal microcephaly ranging from -3.6 to -4.0 SD. 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. Sources: Literature; 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 Intellectual Disability panels with a suggested Green classification at the next major review. |
