1/3. Hypotriploidy 68,XX: a new case report and review of earlier cases.We report a prematurely born patient with a 68,XX karyotype. She presented with syndactyly of 2nd and 3rd toes, minor facial features, microcephaly, slender hands, bicuspid aortic valve, patent ductus arteriosus and hypotonia. Comparison with other reported cases is given.- - - - - - - - - - ranking = 1keywords = triploidy (Clic here for more details about this article) |
2/3. triploidy syndrome. A report on two live-born (69, XXY) and one still-born (69, XXX) infants.Two live-born cases, 69,XXY and one stillbirth, 69,XXX are reported. Further evidence is presented to delineate the triploidy syndrome. Common external and internal features which characterize the triploidy syndrome are low-set ears, hypertelorism, colobomata, syndactyly, simian creases, microphallus, undescended testes, scrotal aplasia, anomalous heart and hypoplasia of kidneys and adrenals. The triploidy syndrome encompasses features found in trisomies 13, 18 and 21. We suggest that the abnormal development of the triploidy infants is the result of the mentioned trisomies and their subsequent effect on the remaining genome.- - - - - - - - - - ranking = 1keywords = triploidy (Clic here for more details about this article) |
3/3. fluorescence in situ hybridisation on formalin fixed fetal tissue in the diagnosis of chromosomal syndromes.Two cases of stillborn children with multiple congenital anomalies are presented. No routine karyotyping was performed. After dysmorphologic evaluation a tentative diagnosis of trisomy 18 and triploidy, respectively, could be made. fluorescence in situ hybridisation with several chromosome specific probes on formalin fixed paraffin embedded tissue confirmed the suspected diagnosis in both cases. In view of the important consequences for the parents (relatively low recurrence risk, availability of prenatal diagnosis in subsequent pregnancies) fluorescence in situ hybridisation for the common chromosomal aneuploidies should be performed in selected cases of stillborn fetuses with multiple congenital malformations.- - - - - - - - - - ranking = 0.25keywords = triploidy (Clic here for more details about this article) |
