PG - 115-7 AB - The retinoblastoma (Rb) gene probe p123 M1.8 and p68 Rs2.0 were used to study the frequencies of the Bam HI and Rsa I restriction fragment length polymorphisms (RFLPs) in the RB gene among the population of Han nationality in Guangdong province. The result showed that the heterozygote rate of the Rsa I locus was only 55.0%, remarkably different from reports in the literature. Linkage study of the Bam HI and the Rsa I RFLPs demonstrated that 10.5% of the Rsa I polymorphic loci were heterozygous for the Bam HI RFLP. Thus the combined use of the two RFLPs can give information for about 65.5% of the population. FAU - Wei, J AU - Wei J AD - Sun Yat-sen University of Medical Sciences, Guangzhou.
