CHD7, an ATP-dependent chromodomain helicase DNA-binding protein, and SOX2, an SRY-related HMG box pioneer transcription factor, are known to contribute to vestibular and auditory system development, but their genetic interactions in the ear have not been explored. Here, we analyzed inner ear development and the transcriptional regulatory landscapes in mice with variable dosages of\n                    <jats:italic>Chd7<\/jats:italic>\n                    and\/or\n                    <jats:italic>Sox2<\/jats:italic>\n                    . We show that combined haploinsufficiency for\n                    <jats:italic>Chd7<\/jats:italic>\n                    and\n                    <jats:italic>Sox2<\/jats:italic>\n                    results in reduced otic cell proliferation, severe malformations of semicircular canals, and shortened cochleae with ectopic hair cells.

Data from genome-wide RNA-sequencing and CUT&amp;Tag studies in the otocyst show that CHD7 regulates\n                    <jats:italic>Sox2<\/jats:italic>\n                    expression and acts early in a gene regulatory network to control expression of key otic patterning genes, including\n                    <jats:italic>Pax2<\/jats:italic>\n                    and\n                    <jats:italic>Otx2<\/jats:italic>\n                    .
