Klinefelter's syndrome in nontwin brothers and maternal XX/XXX mosaicism.
A case of two nontwin brothers, 19 and 17 years old, who had both Klinefelter's syndrome with a chromosomal mosaicism 46 XY/47 XXY, is reported here. The analysis of their mother's karyotype revealed a 46 XX/47 XXX mosaicism. It is hypothesized that the presence of an extra X chromosome in all three subjects could depend on the transmission of two X chromosomes from the mother to the sons or, l...

A 3.3 year old girl with Prader-Willi syndrome (PWS) and mosaicism for two aneuploidies, 47,XXX and 47,XX,+15, is presented. The triplo-X cell line was found in white blood cells and fibroblasts, the trisomy 15 cell line in 50% of the fibroblasts.

Contrary to the expected XX/XY sex chromosome complements in hermaphroditism, a variety of karyotypes have been reported instead. Dewhurst et al. (1965) summarized from published reports the karyotypic findings in 27 patients with convincing evidence ofhermaphroditism, as follows: 46,XX (17); 46,XY (2); 46,XX/47,XXX (1); 46,XX/46,XX + Frag (1); 46,XX/46,XY (3); 46,XX/47,XXY/ 49,XXYYY (1); 46,XX...
متن کاملNoninvasive prenatal test for the pregnancy with Turner syndrome mosaicism 45, X/47, XXX: A case report
present as an abnormal maternal screening test result or abnormal ultrasonography finding, this condition is not typically associated with structural abnormalities or abnormal maternal serum screening profiles. Therefore, prenatal diagnosis of Turner syndrome is complicated, and most cases are diagnosed incidentally or postnatally. In 1997, Lo et al. [3] demonstrated that fetal cell-free DNA (c...
