The current BAFopathy episignature is trained on positive cases with pathogenic variants in ARID1B, ARID1A, SMARCB1, SMARCA2, and SMARCA4. Since BAF complex–associated ARID2 positive references are not represented, it was not possible to confidently rule in/out a BAFopathy episignature. Here, SMARCA2 is linked to BAFopathy.
