The pregnancy was terminated and fetal autopsy revealed minor facial abnormalities (long philtrum, up-slanting palpebral fissures and a broad nasal bridge).

The chromosomes were also examined with high-resolution banding with particular emphasis on those chromosomes (#1, 10, 20, and 22) that have(More)
