Two Cases of Partial Trisomy 4p and Partial Trisomy 14q

Two 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...

A third case of de novo partial trisomy 4p.

Interestingly, the previously reported patient with a different but overlapping deletion of chromosome 12 long arm (q13.3-q21.1) and the subject of this report have only a few features in common (table). The deletion in each includes the portion 12q13.3 to q21. 1. It is unclear whether the small difference in the portion of 12q deleted accounts for the fact that they do not resemble each other ...

Sonographic Findings in Partial Type of Trisomy 18

De novo case of a partial trisomy 4p and a partial monosomy 8p.

The extent of clinical expression in cases of segmental aneuploidy often varies depending on the size of the chromosomal region involved. Here we present clinical and cytogenetic findings in a 5-month old boy with a duplication of a chromosomal segment 4p16.1-->4pter and a deletion of a chromosomal segment 8p23.1-->8pter. His karyotype was determined by applying classical GTG banding and FISH m...
