Trisomy 20p from maternal t(3;20) translocation.

Abstract
A case of trisomy 20p resulting from a maternal translocation t(3;20) is described. QM and BUdR banding techniques were used for its identification. A round face with oblique palpebral fissures, strabismus, cardiac and vertebral abnormalities, mild psychomotor retardation, together with poor coordination and speech impediment, are the most typical features of the proband.
