چکیده
We describe a stillborn female infant with severe intrauterine growth retardation and multiple congenital anomalies. She was found to have a deletion of 13q22----qter and trisomy of 18p11.2----pter, resulting from a maternal balanced translocation.

متن کاملPrenatal Diagnosis and Postnatal Followup of Partial Trisomy 13q and Partial Monosomy 10p: A Case Report and Review of the Literature
We report prenatal diagnosis and postnatal findings of a fetus with partial trisomy of 13q21.33-qter and partial monosomy of 10p15.3-pter. The mother is a known carrier of a balanced translocation, t(10;13)(p15.3;q21.33), ascertained by history of one miscarriage and two neonatal deaths. The fetal karyotyping on cultured amniocytes showed 46,XX,der(10)t(10;13)(p15.3;q21.33). Oligonucleotide arr...
متن کاملMolecular and cytogenetic characterisation of an unusual case of partial trisomy/partial monosomy 13 mosaicism: 46,XX,r(13)(p11q14)/46,XX,der(13)t(13;13)(q10;q14).
A female infant with multiple malformations and mental retardation was noted to have a rare de novo chromosome abnormality involving mosaicism with two cell lines, one with a ring chromosome 13, and the other with partial trisomy 13 owing to a complex rearrangement. Cytogenetic examination excluded the presence of a t(13q;13q) cell line and showed a cell line with a marker chromosome containing...
متن کاملMosaic and partial monosomy of chromosome 21 in a case with low platelets count
Background Monosomy is defined as the presence of only one chromosome instead of two in humans. Partial monosomy occurs when only a portion of the chromosome is present in a single copy, while the rest has two copies. It can occur in unbalanced translocations or deletions. Case report In this report, a 6 years old girl was presented who was referred to the Pediatric Dep, Shahid Sadoughi Ho...
متن کاملSevere mental retardation in six generations of a large South African family carrying a translocation t(6;10)(q27;q25.2).
Partial monosomy 10q25.2----qter, detected in a newborn baby with multiple congenital abnormalities, was found to be derived from a balanced maternal translocation t(6;10)(q27;q25.2). The pedigree of six generations of the family is presented. In an extensive cytogenetic study of this family, the chromosome complements of 57 subjects, potentially capable of carrying some form of this translocat...
