Abstract excerpt
Chromosome analysis of amniotic fluid cells from a 17-week-old fetus with a nuchal cystic hygroma showed a 45,X/47,XX,+21 karyotype. Analyses of cord blood lymphocytes, skin fibroblasts, amniotic membrane, and chorionic villi demonstrated both cell lines in various proportions. We studied the ori...
