Benign, criteria provided, single submitter | curation | Centre for Population Genomics, CPG | Mar 22, 2024 | This variant has been collected from RettBASE and curated to current modified ACMG/AMP criteria. Based on the classification scheme defined by the ClinGen Rett/Angelman-like Expert Panel for Rett/AS-like Disorders Specifications to the ACMG/AMP Variant Interpretation Guidelines VCEP 3.0, this variant is classified as benign. At least the following criteria are met: The allele frequency of this variant in at least one population in gnomAD is higher than the 0.03% threshold defined by the ClinGen Rett/Angelman-like Expert Panel for Rett/AS-like Disorders VCEP 3.0 (BA1). - |
Benign, reviewed by expert panel | curation | ClinGen Rett and Angelman-like Disorders Variant Curation Expert Panel | May 10, 2022 | The allele frequency of the p.Ala201Val (NM_004992) variant in MECP2 is 1.045% in East Asian sub population in gnomAD, which is high enough to be classified as Benign based on thresholds defined by the ClinGen Rett/Angelman-like Expert Panel for Rett/AS-like conditions (BA1). In summary, the p.Ala201Val variant in MECP2 is classified as Benign based on the ACMG/AMP criteria (BA1). - |
