An unusual combination of trisomy 21 and partial trisomy 5q.

Sonographic Findings in Partial Type of Trisomy 18

A case of partial 5q trisomy associated with partial 7q monosomy.

A 1-year-old girl with partial 5q trisomy and partial 7q monosomy had ocular abnormalities that included bilateral blepharoptosis and Leber's congenital amaurosis. A single bright-flash electroretinogram (dark-adapted, white stimulation) disclosed subnormal bilateral responses. Her maculas showed a reddish spot surrounded by a broad, greyish retinal zone. Cytogenetic studies disclosed deletion ...

Simultaneous partial monosomy 10p and trisomy 5q in a case of hypoparathyroidism.

We report a case of monosomy for the distal region of the short arm of chromosome 10 (p13----ter) associated with trisomy for the terminal region of the long arm of chromosome 5 (q35.2----ter) that had originated from adjacent 1 segregation of a maternal reciprocal balanced translocation (5;10)(q35.2;p13). We review the clinical findings of previously reported cases of both partial monosomy for...

Partial trisomy for 5q and monosomy for 12p in a liveborn child as a result of a complex five breakpoint chromosome rearrangement in a parent.

A balanced complex chromosome rearrangement (CCR) involving four chromosomes is very rare and may lead to different types of aneuploid germ cells. We report a liveborn child with multiple congenital anomalies and an apparently balanced translocation, t(11;12). High resolution chromosome analysis in the mother showed a CCR involving chromosomes 5, 11, 12, and 16. In situ hybridisation showed tha...

Partial trisomy for short and long arm of chromosome no. 5: Two cases of two possible syndromes.

We report 2 patients from different families with malformation-retardation syndromes caused by a partial trisomy of the long and of the short arm of chromosome 5, respectively (case 1: 46,XX,der(3),t(3;5)(p27;p13)mat; case 2: 46,XY,der(22),t(5;22)(q33;q13)pat). Several members of these families were balanced translocation carriers. Our cases are compared with those cited in the literature. The ...
