and 17q24.3–q25.3) and one significant (20q13.12–q13.32) linkage regions. In fact, the regions on chromosomes 5 and 20 expand two of the regions reported in our 2008 review. The region on chromosome 17 reported by Han et al.37 verified one of the regions detected in only one sample before 2008, which makes it a newly nominated linkage peak (Table 1).34 Please refer to Li34 and Table 1 for detailed information on the 14 nominated linkage regions. Figure 1 also shows updated linkage results after incorporating the findings reported after 2008 by Han et al.37
