Prenatal diagnosis of tetraploidy: a case report.

American journal of medical genetics - 1 Feb 1993

Coe S J, Kapur R, Luthardt F, Rabinovitch P, Kramer D

Abstract excerpt

We report on the second trimester prenatal diagnosis of an apparently nonmosaic tetraploid fetus, 92,XXYY. Indications for cytogenetic studies of the fetus included abnormal ultrasound findings and abnormal maternal serum levels of alpha-fetoprotein (AFP)/estriol. Chromosome analysis of amniocytes documented tetraploidy, a finding confirmed by flow cytometry of several fetal tissues. Autopsy findings in the fetus...
