Evidence for two active X chromosomes in a human XXY triploid.

D D Weaver, S M Gartler.   

Abstract

A human XXY chromatin negative triploid culture has been found to have both the A and B isozymes of glucose-6-phosphate dehydrogenase, as well as an intermediately migrating AB (hybrid) band. This finding indicates that the cells in this culture each possess 2 active X chromosomes. Possible mechanisms producing the abnormalities seen in this disorder are presented and discussed.
