Precarious acrocentric short arm in prenatal diagnosis: no chromosome 14 polymorphism, but trisomy 17p

Precarious acrocentric short arm in prenatal diagnosis: no chromosome 14 po lymorphism, but trisomy 17p: we report on a girl with multiple congenital a bnormalities and a prenatally diagnosed 46,XX.14p+ de novo karyotype. Fluor escence in situ hybridization (FISH) demonstrated that the extra material o n the short arm of chromosome 14 was not just a polymorphism, but that it o riginated from chromosome 17. The phenotypic findings of this patient with pure trisomy 17p are compared with those of ten previously published cases.
