Of 47 cases with information on phenotypic outcome, 42 cases (89\u00b74 percent) were reported to be associated with a grossly normal male phenotype. Three cases (6\u00b74 percent) were diagnosed as having mixed gonadal dysgenesis with internal asymmetrical gonads. Two other cases were questionably abnormal. In 40 cases with successful cytogenetic confirmatory studies, the overall rate of cytogenetic confirmation of 45,X\/46,XY from tissues derived from fetus\/liveborn\/placenta was 70\u00b7O per cent. This review shows a major difference in the phenotypic outcome between postnatal diagnosis and prenatal diagnosis. Due to the ascertainment bias, almost all known patients with postnatal diagnosis of 45,X\/46,XY mosaicism are phenotypically abnormal. Therefore, caution must be used in translating information derived from postnatal diagnosis to prenatal diagnosis. This review calls for collection of more data on 45,X\/46,XY mosaicism diagnosed prenatally, more long\u2010term follow\u2010up of liveborn infants, and pathological studies of all abortuses. Emphasis is placed also on the importance of genetic counselling, ultrasound examination, and cytogenetic confirmation.<\/jats:p>","DOI":"10.1002\/pd.1970090106","type":"journal-article","created":{"date-parts":[[2007,3,3]],"date-time":"2007-03-03T20:58:42Z","timestamp":1172955522000},"page":"31-48","source":"Crossref","is-referenced-by-count":71,"title":["Prenatal diagnosis of 45,X\/46,XY mosaicism\u2014A review and update"],"prefix":"10.1002","volume":"9","author":[{"given":"Lillian Y.
