Abstract excerpt
The highly polymorphic human DXS16 locus on Xp22 contains a BglII restriction fragment length polymorphism with 33% heterozygosity. We report that methylation of the HpaII site, 3.1 kb away from this restriction fragment length polymorphism, correlates with X-inactivation. The BglII polymorphism distinguishes between the maternal and paternal alleles, and HpaII digestion identifies their methylation status. The...
