TEXT

▼ Clinical Features

Bonsch et al. (2001) studied a 4-generation German family in which members had severe progressive nonsyndromic hearing loss. Onset was during the first decade of life and first involved the higher frequencies; in the following decades, the middle and lower frequencies became affected.


▼ Mapping

Bonsch et al. (2001) performed a genome scan with polymorphic microsatellite markers in a German family segregating nonsyndromic hearing loss and mapped the disorder, designated DFNA18, to a 10-cM region on 3q22 with a maximum 2-point lod score of 3.78 at theta = 0.0 for marker D3S1541. The DFNA18 locus was excluded from neighboring deafness loci DFNB15 (601869) and USH3 (276902), but the critical region overlapped with the locus for dystrophia myotonica-2/proximal myotonic myopathy (DM2; 602668) locus, in which hearing impairment has been described as part of the phenotype in some patients. Neurologic examination of the affected individuals of the DFNA18 pedigree gave completely negative results.


▼ Molecular Genetics

Exclusion Studies

Bonsch et al. (2003) excluded ZNF9 (116955), the gene mutant in DM2 (602668), as the disease gene in DFNA18.
