The parental origin of the single X chromosome in Turner syndrome: lack of correlation with parental age or clinical phenotype.

American journal of human genetics - 1 Apr 1991

Abstract excerpt

We have used X- and Y-linked RFLPs to determine the origin of the single X chromosome in 25 live-born individuals with Turner syndrome. We determined that 18 individuals retained a maternal X (Xm) and that seven retained the paternal X (Xp). No occult mosaicism was detected. We found no differences in either maternal or paternal ages for the two groups. The ratio of maternal X to paternal X is just over 2:1,...
