Characterization of a small supernumerary ring X chromosome by fluorescence in situ hybridization.

American journal of medical genetics - 1 Dec 1993

Abstract excerpt

We report on a male with mild learning disabilities who has a supernumerary marker chromosome. The marker chromosome was defined by fluorescence in situ hybridization as a ring X chromosome with breakpoints in the juxacentromeric region. Replication studies suggest that the ring X is late-replicating. However XIST, a gene in the X inactivation centre interval which is expressed exclusively from the inactive X...
