Criteria Specification Approval History
Criteria Specifications for this VCEP
Evidence submitted by expert panel
Rett and Angelman-like Disorders VCEP
The allele frequency of the c.-5del variant in SLC9A6 (NM_006359.2) is 0.02% in European (non-Finnish) sub population in gnomAD v2, which is high enough to meet the BS1 criteria based on thresholds defined by the ClinGen Rett/Angelman-like Expert Panel for Rett/AS-like conditions (BS1). Splice prediction analysis, using multiple computational tools does not suggest an impact to splicing (BP4). The c.-5del variant is observed in the hemizygous state in at least 2 unaffected individuals (internal database - GeneDx) (BS2). In sumarry, the c.-5del variant in SLC9A6 is classified as benign based on the ACMG/AMP criteria (BS1, BP4, BS2).
