We present a prenatal diagnosis of a de novo homologous Robertsonian translocation involving both chromosomes 15. Amniocentesis was performed on a 36-year-old woman at 16.5 weeks of gestation. Chromosome analysis documented a 45,XX,der(15;15) (q10;q10) chromosome pattern. No evidence of a deletion w

✦ Synopsis
A case of X-autosome translocation was diagnosed prenatally [46,X,t(X;9)(p21.3∼ 22.1;q22]. We describe the use of fluorescence in situ hybridization (FISH) to estimate the integrity of the Duchenne muscular dystrophy (DMD) gene. X-inactivation studies were used as well to assess the probability of phenotypic abnormalities associated with functional partial disomy X and monosomy 9.

We report a case of a newborn female with minor dysmorphic features and hypoplastic left heart. Chromosome studies showed that she was the carrier of an unbalanced translocation between the X-chromosome and chromosome 16, resulting in monosomy for Xp and trisomy for 16q. Only a handful of partial tr

We evaluated demographic factors and factors specific to the current pregnancy, and their relationship to the decision to continue or terminate a pregnancy after prenatal diagnosis of Down syndrome.
