A prenatally detected case of a rare mosaic tetrasomy 12p/trisomy 12p is reported, presenting as the well‐known accessory isochromosome 12p and a supernumerary single 12p marker in 17/24 and 6/24 clones of cultured amniotic fluid cells, respectively. The chromosomal nature of both marker chromosomes was investigated in cultured amniotic fluid cells by fluorescent in situ hybridization with various probes: the 12‐centromeric probes pa12H8 and D12Z3, a whole chromosome 12 paint, and the chromosome 12p‐specific paint M28. DNA analysis revealed a maternal origin of the extra 12p material. After counselling, the parents requested termination of pregnancy. Inspection and autopsy of the fetus revealed many of the dysmorphisms and internal structural abnormalities of the Pallister–Killian syndrome. Copyright
