title: A paracentric inversion of 7q illustrating a possible interchromosomal effect.
abstract: A family is described in which the proband has a rearranged X chromosome involving monosomy Xp and trisomy Xq, while the mother has a paracentric inversion of chromosome 7. It is suggested that the phenomenon of interchromosomal effect may link these observations. A brief review of the published and computer catalogued data on paracentric inversion in man is included.
