Pedigree drawing of family 4153. Black symbols represent individuals with hearing impairment. Clear symbols represent unaffected individuals. The sex of some of the family members was changed to protect the anonymity of the family. Allele sizes in kilobases are indicated beside the upper column of microsatellite markers. Alleles are numbered according to the CEPH Genotype database V10.0 (5). Haplotypes are shown below each individual for whom genotypes are available. For individuals in generation V, maternal haplotypes are displayed on the left-hand side and paternal haplotypes on the right-hand side. Arrows and shaded areas indicate the region of homozygosity.
