Monosomy 22 mosaicism.
The proband, a VA year old female child, was the first issue of a healthy couple (Fig. 1). The second issue which is a male child, is absolutely normal. The age of the mother and father was 30 and 35 years, respectively. The marriage was a non-consanguineous one. A detailed pedigree analysis revealed no chromosomal or genetic abnormality in the family. There was no previous history of miscarria...
متن کاملPrenatal detection of monosomy 18p and trisomy 18q mosaicism with unexpected fetal phenotype.
A mosaic karyotype 46,XX,del(18)(p11)/46,XX,-18,+?i(18q) was found in cultured amniotic cells. Fetal blood sampling confirmed the presence of both cell lines. The pregnancy was terminated and the two cell lines were demonstrated in varying proportions in the fetal tissues. The few abnormal features seen in the fetus may represent a mild expression of the 18p-- phenotype inhibiting the effects o...
متن کاملPartial 10q trisomy with partial 12q monosomy.
A case of partial trisomy 10q with partial monosomy 12q is reported. The chromosomal abnormalities resulted from a paternal balanced, reciprocal translocation involving chromosomes 10 and 12, which, to the best of our knowledge, has not been previously described.
متن کاملThe development of monosomy 19 mouse embryos.
In general, autosomal monosomy is lethal much earlier in mammalian development than autosomal trisomy. In an attempt to understand why monosomy is so deleterious, we have begun to characterize the development of mouse embryos monosomic for chromosome 19. A dramatic loss of monosomy 19 embryos was found to occur between days 3 and 4 of development. This loss occurred both in vivo and in vitro an...
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...
