Role of DFNB1 mutations in hereditary hearing loss among assortative mating hearing impaired families from South India

摘要

BackgroundDFNB1, the first locus to have been associated with deafness, has two major genes GJB2 & GJB6, whose mutations have played vital role in hearing impairment across many ethnicities in the world. In our present study we have focused on the role of these mutations in assortative mating hearing impaired families from south India.
