Trisomy 13 ascertained in a survey of spontaneous abortions.
In a series of 2922 karyotyped spontaneous abortions, 62 were found to be trisomic for chromosome 13, 46 having a simple trisomy and 16 a translocation trisomy. The epidemiology of this series of trisomy 13 conceptuses is presented and compared to that of trisomy 13 ascertained from other populations. In most compared parameters the trisomy 13 spontaneous abortions are very similar. However, th...
متن کاملSurvival in trisomy 13 and trisomy 18 cases ascertained from population based registers.
Although long term survivors are well documented, infants with the autosomal trisomies 18 (Edwards syndrome) or 13 (Patau syndrome) usually die in the first few days or weeks of life. Accurate estimates of life expectancy are few, particularly in the case of trisomy 13. There have been six population surveys of survival in trisomy 18, comprising 430 unselected cases. In contrast there have been...
متن کاملBalanced Chromosomal Rearrangement in Recurrent Spontaneous Abortions: A Case Report
One of the major causes of spontaneous abortion before the fourth month of pregnancy is chromosomal abnormalities. We report an unusual case of a familial balanced chromosomal translocation in a consanguineous couple who experienced 4 spontaneous abortions. Chromosomal studies were performed on the basis of G-banding technique at high resolution and revealed 46, XX, t (16 6) (p12 q26) and 46, X...
متن کاملParental origin of triploidy and D and G trisomy in spontaneous abortions.
A cytogenetic study of 15 triploid spontaneous abortuses, 12 trisomic abortuses, and their parents was carried out using the Q-banding technique. Polymorphic regions in abortus chromosomes were compared to corresponding regions of parental chromosomes to determine the origin of the extra chromosomes. Using marker chromosomes it was found that 7 triploids and only one trisomy were informative. T...
