Phenotypic variability in a seven-generation Swedish family segregating autosomal dominant hearing impairment due to a novel EYA4 frameshift mutation.

Abstract excerpt

Linkage to an interval overlapping the DFNA10 locus on chromosome 6q22-23 was found through genome wide linkage analysis in a seven-generation Swedish family segregating postlingual, autosomal dominant nonsyndromic sensorineural hearing impairment. A novel heterozygous frame-shift mutation (c.579_580insTACC, p.(Asp194Tyrfs*52)) in EYA4 was identified that truncates the so-called variable region of the protein....
