Neonatal deafness gene screening can not only detect children with congenital deafness caused by GJB2 gene but also warn of large vestibular aqueduct syndrome caused by SLC26A4 gene and drug-induced deafness caused by MT-RNR1 gene, aiming to effectively prevent the occurrence of delayed deafness and drug-induced deafness. Here, NR4A2 is linked to deafness.
