title: Paracentric inversion of chromosome 14 plus rare 9p variant in a couple with habitual spontaneous abortion.
abstract: A couple presenting with habitual spontaneous abortion both showed a chromosome rearrangement. The male had an apparently balanced paracentric inversion of chromosome 14 - 46,XY,inv(14) (q11q32). The female had a karyotype with a rare large short arm variant of chromosome 9 - 46,XX,var(9) (p11p21). Testing of a living normal child showed that he had inherited both rearrangements. Family testing showed the chromosome 9 variant in three generations, with all carriers being of normal phenotype and intelligence. This study confirms that the presence of more than one chromosomal rearrangement can be compatible with normal development. This is useful for genetic counselling. Nevertheless when such cases arise, each must be individually assessed.
