چکیده
adrenals. Autoradiography of skin fibroblast culture demonstrated that the cell line with 48 chromosome included a distinctly late-labelled X chromosome and an extra D chromosome labelling as expected for No. 13. The labelling in the 47 chromosome cell line also confirmed the extra D to be No. 13. No euploid cells were found. Chromosome analysis of peripheral blood from each parent was normal.

Robertsonian translocations (RBT) are associated with an increased risk of aneuploidy. Single RBT carriers are the most common balanced rearrangement among the carrier couples with the history of spontaneous abortion. However, double Robertsonian translocations (DRBT), in which two balanced RBT occur simultaneously, are an extremely rare condition. A 9-year-old mentally normal girl with mu...
متن کاملReproductive possibilities for balanced translocation (14) carriers in families with partial trisomy of proximal 14q.
Two cases of 14q proximal partial trisomy in sisters from the same family are reported. Clinical features included craniofacial dysmorphism, skin depigmentation, slight anomalies of the limbs, muscular hypertonia, and physical and mental retardation. The third sister had an abnormal phenotype, different from that of her sibs, and proved to be a carrier of a balanced translocation (2;14)(q36;q21...
متن کاملTwo Cases of Partial Trisomy 4p and Partial Trisomy 14q
We present clinical and cytogenetic data on 2 cases of partial trisomy 4p and partial trisomy 14q. Both patients had an extra der(14)t(4;14)(p15.31;q12) chromosome due to a 3:1 segregation from a balanced translocation carrier mother. Array analyses indicated that their chromosomal breakpoints were similar, but there was no relationship between the 2 families. Both patients showed prominent gro...

We are reporting a case of 47 chromosome complement with an extra rearranged chromosome 22pter→22qll:: llq23 → llqter in a child with multiple malformations whose mother has a balanced reciprocal translocation t(1l,22) with a history of two previous abortions. We emphasize the importance of family study in such cases.

A case of trisomy 14q mosaicism is described and compared with three other similar reported cases. The clinical picture is characterised by severe developmental retardation, failure to thrive, and somatic abnormalities including skeletal asymmetry, high arched or cleft palate, and low set dysplastic ears. The present chromosome imbalance probably resulted from dissociation of a balanced 14q15q ...
