Abstract
Among chromosomal analyses performed in 23 couples with a history of 2 or more spontaneous abortions, 5 women had mosaicism of the sex chromosomes, 46XX/47XXX but all the men had normal 46XY chromosomal complements. Of the fetuses of mothers with sex chromosome mosaicism, 75% were abnormal. Of these pregnancies, 50% ended in abortion and 1/3 of the infants exhibited a chromosomal or physical abnormality. The possible effect of sex chromosome mosaicism on outcome of pregnancy is emphasized.
