Several patients with X chromosome structural abnormalities have been more severely affected clinically than expected. Since bends at Xq13-21 have been associated with inactivation, the authors scored bends retrospectively in 62 patients with X chromosome aneuploidy and 21 cases with structural abnormalities of the X chromosome. They found that patients with 2 X inactivation sites where one X was structurally abnormal had significantly fewer cells with X bends than normal 46,XX. In addition, these patients also showed X bends on the normal X more often than would be expected if non-random X inactivation of the abnormal X chromosome was occurring. Five of the 6 patients with a short or long arm deletion or paracentric inversion of Xq were mentally retarded or had other congenital anomalies not usually associated with Turner syndrome. This suggests to them that these clinical findings may be related to interference with X inactivation patterns in cells with a structurally abnormal X chromosome.
