Abstract
We present a prenatal predictive diagnosis of Prader-Willi syndrome ar ising as a result of maternal heterodisomy for chromosome 15. The diag nosis arose following chorionic villus sampling which showed a mosaic trisomy 15 karyotype with a chromosomally normal follow-up amniocentes is. Molecular studies on DNA extracted from cultured amniocytes showed no evidence of a paternal allele at two widely separated loci and thi s was taken as evidence of maternal disomy predictive of Prader-Willi syndrome in the fetus.
