YAC contig of the DFNB7/11 interval. Individual YAC clones are represented by lines, STS amplification by solid circles, and no STS amplification by open circles. The region spanning D9S936, D9S301, and D9S1806 appears to be deleted in YAC 857G6 based on marker order data from the PAC contig. The DFNB7 andDFNB11 intervals are shown. Brackets surround groups of STSs that could not be ordered based on YAC data alone.
