Studies have shown that DNAm profiles at subsets of CpGs overlap between individuals with BAFopathies carrying variants in SMARCA2 that cause NCBRS, and in ARID1B, SMARCB1, and SMARCA4 that lead to Coffin-Siris syndromes type 1, 3, and 4, respectively. This evidence concerns the gene SMARCB1 and BAFopathy.
