Trisomy 12 mosaicism was found in a 36-year-old woman with minor abnormalities, neuromuscular abnormalities, and moderate mental retardation. Trisomy 12 was present in 13% of the lymphocytes but not in skin fibroblasts. Previous reports of dup (12p) and dup(12q) are reviewed. To our knowledge this is the first report of a 'complete' trisomy 12 in a liveborn individual.
