Genomic testing can aid in treatment of childhood hearing loss

Advances in understanding the diverse genetic causes of childhood-onset hearing loss suggest that genomic testing could help with treatment planning, including appropriate therapy timing.

Advances in understanding the diverse genetic causes of childhood-onset hearing loss suggest that genomic testing could help with treatment planning, including appropriate therapy timing.Even if a child with hearing loss did not receive a diagnosis from genetic testing a few years ago, very rapid recent progress in genomics makes re-testing worthwhile, according to scientists in this field.Hearing loss, usually stemming from sensory problems in the inner ear, affects about 1 in 400 newborns in the United States.About half of these children have a genetic cause for their hearing loss.

More than 120 genes and thousands of different genetic variants can lead to childhood hearing loss.Virtually all children with genetic hearing loss have a mutation or mutations in only one gene.
