CHD7 gene, located at chromosome 8 (8q12) and starting at 61.59 Mb from the p-arm telomere, has
a genomic size of 188 kb and consists of 38 exons. It encodes for the chromodomain helicase DNA
binding protein, a member of the chromodomain family. In human neural crest cells, CHD7 forms a protein
complex with PBAF (polybromo- and BRG1-associated factor-containing complex) that regulates
chromatin structure, gene expression and embryonic development
