High prevalence of syndromic hearing loss in Mexican children undergoing cochlear implantation.

Objective: Studies evaluating genetic sensorineural hearing loss (SNHL) in Hispanic and Latino populations using genomic technologies are lacking. Recent data has shown that Hispanic and Latino children display lower genetic diagnostic rates despite similar prevalence rates of SNHL to their Asian and White counterparts, thus negatively affecting their clinical care. Our objective was to determine the genetic contribution to SNHL in a population of Mexican children undergoing evaluation for cochlear implantation.
