title: A novel autosomal dominant non-syndromic deafness locus (DFNA48) maps to 12q13-q14 in a large Italian family.
abstract: Non-syndromic hearing loss is the most common sensory disorder in humans; 15%-20% of cases are transmitted as a dominant trait (NSDA) with 40 loci having been mapped and 16 genes having been identified. Here, we report the mapping of a novel NSDA locus, DFNA48, to chromosome 12q13-q14 in a large multigenerational Italian family. A maximum lod score of 3.31 was obtained with marker D12S83, whereas markers D12S347 and D12S1703 defined a region of approximately 18 cM. Positional candidate genes are being screened for deafness-causing mutations.
