Prenatal morphology of partial monosomy 18q

Prenatal diagnosis, performed in a woman with reciprocal translocation (9:18), disclosed partial monosomy 18q in a fetus. Morphologic studies of this fetus revealed dysplastic face and ears, a high palate, hypomotility of joints, an accessory spleen and anomalous dermatoglyphics. Biochemical examination detected a decrease of most amino acids, which is typical for many chromosomal syndromes.
