Description

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 2.0, this variant is classified as Likely benign. At least the following criteria are met: The allele frequency of this variant in at least one population in gnomAD is between 0.008% and 0.03% (BS1). The variant is observed in at least 1 individual with no features of Rett Syndrome (BS2_Supporting). Synonymous or intronic variant outside donor and acceptor splice regions where splicing prediction algorithms do not support significant splicing alteration (spliceAI score <=0.1) (BP4, BP7).
