متن کاملDe 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...
متن کاملRecurrent omphalocele with partial trisomy 3q and partial monosomy 11q.
To the Editor: Omphalocele is not an uncommon malformation; however, it usually occurs sporadically with less than a 1% recurrence risk (Winter & Baraitser 1991 ). We present recurrence of omphalocele in siblings with partial trisomy 3q and partial monosomy 1 lq as the unbalanced product of a t (3; 1 1 ) (q21;q23)mat. This was the fourth pregnancy of an unrelated couple. The mother had one heal...
