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