Partial trisomy 6p and partial trisomy 22 resulting from 3:1 meiotic disjunction of maternal (6p;22q) translocation.
A male infant, partially trisomic for a small segment of chromosomes 6 and 22 resulting from a maternal translocation, is described. Comparison of the phenotypic features of the proband with those noted in partial 6p and partial 22 trisomies revealed some common features found in both chromosome anomalies but especially reinforced those features thought to be characteristic of 6p trisomy syndrome.
متن کاملPartial trisomy for 5q and monosomy for 12p in a liveborn child as a result of a complex five breakpoint chromosome rearrangement in a parent.
A balanced complex chromosome rearrangement (CCR) involving four chromosomes is very rare and may lead to different types of aneuploid germ cells. We report a liveborn child with multiple congenital anomalies and an apparently balanced translocation, t(11;12). High resolution chromosome analysis in the mother showed a CCR involving chromosomes 5, 11, 12, and 16. In situ hybridisation showed tha...
متن کاملComplex chromosomal rearrangement leading to partial trisomy 22.
We have examined a boy with a peculiar facial appearance and mental retardation. Cytogenetic studies showed 47,XY, monosomy 22, two marker chromosomes, M1 and M2. The karotype is interpreted as functionally partial trisomy 22. Chromosome analyses of both parents and three sibs were normal.
متن کاملFamilial complex chromosome rearrangement ascertained by in situ hybridisation.
A complex familial chromosome translocation has been ascertained by combining classical cytogenetics and CISS (chromosomal in situ suppression). Cytogenetic analysis of a chorionic villus sample with G banding showed a 47,XX,-2, +der(2)t(2;22),+der(22)t(2;22) karyotype. Analysis of peripheral blood lymphocytes from the parents by G banding and CISS showed a more complex translocation in the fat...
متن کاملFamilial translocation with partial trisomy of 13 and 22: evidence that specific regions of chromosomes 13 and 22 are responsible for the phenotype of each trisomy.
A newborn infant with clinical and pathological findings typical trisomy 13 and 22 syndromes had an extra chromosome which was a derivative chromosome from maternal balanced translocation affecting Nos. 13 and 22; 47,XY,+der(22),t(13:22)(q22:q12)Mat. The presence of extra specific euchromatic regions of No. 13(13q22 and/or 13q34) and No. 22 (22q11) seem to be responsible for the trisomy 13 and ...
