Analysis of X-chromosome inactivation patterns in women has been used to assess the clonality of various tumors. In this report, we analyzed 27 liver tumors in women, including 18 samples obtained by the performance of ultrasonically guided thin-needle biopsies. By analysis of the heterogeneity of p

β¦ Synopsis
Using a human phosphoglycerate kinase (PGK) cDNA probe, we have identified a common Pst I restriction site polymorphism on the human X chromosome in all ethnic groups studied. The polymorphic Pst I site was absent in 40.4% of 94 X chromosomes of unrelated subjects. Heterozygous females can only be detected by the combined use of a Pst I digest and a Xba I + Pst I digest due to the presence of autosomal and X-linked bands of the same size in simple Pst I digests. Since 48% of females are heterozygotes for the Pst I polymorphism, this site can serve as a useful genetic marker on the long arm of X chromosome in man.
