[Distal trisomy 15q]

A patient with distal 15q trisomy resulting from malsegregation of a maternal t(13;15)(q33;q21.2) showed the following symptoms: micro-dolichocephaly, palpebral fissures slightly oriented downwards and outwards, a large nose, pronounced micrognathia, prominent authelices, ligamental abnormalities, osseous malformations evocative of diastrophic dwarfism, severe congenital heart defect, and profound encephalopathy. He died at five months of age. This observation is compared with two others from the literature.
