Title
A nonmosaic 45,X karyotype in a mother with Turner's syndrome and in her daughter
Author
Abstract
Objective: To describe a woman with a nonmosaic (45,X) form of Turner's syndrome who gave birth to a girl with 45,X Turner syndrome. Design: Patient report. Setting: Outpatient clinic of a university hospital. Patient(s): A woman with typical phenotypic features of Turner syndrome and a 45,X karyotype and her daughter with the same karyotype. Intervention(s): None. Main Outcome Measure(s): Routine karyotype analysis on 200 white blood cells on two different occasions, on skin fibroblasts (1,000 mitoses) and on ovarian fibroblasts. Translocation of X-chromosome material was investigated by a complete X paint and fluorescent in situ hybridization analysis. Result(s): The patient had a spontaneous puberty and became pregnant on three occasions. Her first daughter has a normal karyotype, the second pregnancy ended in spontaneous abortion, and after the third pregnancy, a girl was born with a 45,X karyotype. Karyotype analysis of a large number of mitoses in three different cell types failed to demonstrate any mosaicism. Translocation of X-chromosome material was ruled out by fluorescent in situ hybridization analysis with an X paint. Conclusion(s): This is a rare case of pregnancy in a nonmosaic Turner syndrome patient and, to our knowledge, is the only one that resulted in a live-born baby with the same karyotype. Cryptic mosaicism could not be found despite thorough investigations. Some hypotheses are presented that may explain this unique event. (C) 2004 by American Society for Reproductive Medicine.
