Ring 17 chromosome detected by amniocentesis.
A fetus with a 46,XX,r(17) karyotype identified initially by amniocentesis and confirmed by banding studies is described. No significant phenotypic abnormalities were identified despite isolation of the ring chromosome from multiple fetal tissues. This paucity of abnormal features of gross development is consistent with findings in 3 previously reported patients with ring 17 chromosomes.
