Abstract
- Abstract We examined 64 normal Japanese chromosomes to determine the heterozygosities and allelic frequencies of 358 dinucleotide-repeat marker loci spanning the whole human genome. Comparisons of the data for each marker in the Japanese population sample with data for the same markers among Caucasian samples in the Genome Database (GDB) revealed a slightly lower average of heterozygosity in Japanese (71% vs 79%). Although the majority of the markers were as informative as in Caucasians, some in our sample were uninformative due to low heterozygosity; 38 loci revealed heterozygosities lower than 50% and 11 of these were less than 30%. Furthermore, allelic distributions at many of the marker loci were quite different in the two racial groups. Since such differences will influence statistical analyses between markers and disease loci, our data will be essential for linkage analyses, sib-ship pair analyses, and association studies involving the Japanese population. Therefore we have archived this database on a home page on the Internet (http://www.ims.u-tokyo.ac.jp/nakamura/Yamane.html). [ABSTRACT FROM AUTHOR]
