Familial partial 14 trisomy.

Sonographic Findings in Partial Type of Trisomy 18

Partial trisomy 7p associated with familial 7p;22q translocation.

A newly described partial trisomy of the short arm of chromosome number 7 is reported in a familial translocation between 7 and 22. The unbalanced translocation was found in one family member, the propositus, and the balanced form in 5 other members. The possibility of this translocation being a rare telomeric attachment previously undescribed in humans is discussed. Prominent clinical features...

Partial trisomy 7 (q32----qter) syndrome in two children.

Two unrelated children are described with a partial trisomy 7 (q32----qter). Their phenotypes are compared with other reported cases with both this trisomy and others of the 7q arm. Several apparently useful pathognomonic features are distinguished. The phenotypic variability between trisomic persons within and between families is discussed. It is suggested that the disparate monosomies always ...

Molecular cytogenetic characterisation of the first familial case of partial 9p duplication (p22p24).

We report on a father and daughter with a partial 9p duplication, dup(9)(p22p24). Their phenotype, albeit mild, is characteristic of partial trisomy 9p. Fluorescence in situ hybridisation (FISH) was used to characterise further and confirm the G banding finding. This is the first reported instance of trisomy 9p occurring in two successive generations. The duplicated segment in these two patient...

Partial trisomy 16 as a result of familial 16;20 translocation.

Although trisomy 16 is well recognised in spontaneous abortuses, it is infrequent in livebirths and there is little information about the clinical effects. We report two sibs with partial trisomy 16q resulting in infant death. Both children were severely growth retarded with small elfin faces, prominent foreheads, low set ears, abnormal external genitalia, and intractable diarrhoea.
