Title: A gene for autosomal dominant hearing loss on the short arm of chromosome 1

Hearing loss is the most common form of sensory impairment and many cases are attributable to genetic causes. The genetic defects underlying several syndromic forms of deafness have been identified, but little is known about the causes of non-syndromic hereditary deafness which accounts for the majority of inherited hearing loss. We report here a large Indonesian family with non-syndromal postlingual hearing loss starting in the high frequencies and showing autosomal dominant inheritance. To locate the gene responsible for the hearing loss in this family, we performed a genome search by genetic linkage analysis with microsatellite markers distributed over the whole genome. We have mapped the gene causing deafness in an extended Indonesian family to chromosome 1p with a multipoint lod score higher than 7. Two other smaller families, showing a similar hereditary hearing loss, were also tested for linkage with chromosome 1p. One family originating from the U.S. was linked to this new locus with a multipoint lod score exceeding 5. In another family from the Netherlands this locus was excluded. The flanking markers D1S255 and D1S211 define a region of 6 cM on chromosome 1p which is likely to contain the deafness gene present in the Indonesian and Americanmore » family.« less
