TRIOBP and hearing loss disorder: In a Polish family with non-syndromic hearing loss, the proband was a 12-year-old patient with hearing loss, and genetic sequencing revealed compound heterozygous mutations in the TRIOBP gene as the cause of their deafness.[12]The study has found that the mutation is not a common cause of deafness, but for the post deaf people, the gene should also be thoroughly analyzed.
