Abstract
Complex chromosome translocations are structural chromosomal rearrangements involving three or more chromosomes and more than two breakpoints. A complex chromosome rearrangement was detected in a phenotypically normal female patient that was referred to the hospital for genetic counseling due to reproductive failure. A cytogenetic evaluation was performed, according to standard method of chromosomal analysis, using G-banding technique. The patient's karyotype showed a balanced complex chromosome rearrangement (BCCR) involving chromosomes 1, 8, and 11 with three breakpoints 1p31, 8q13, and 11q23. The karyotype designed according to ISCN (2013), is 46,XX,t(1;8;11)(p31;q13;q23) (8qter→8q13::1p31→1qter;8pter→8q13::11q23→11qter;11pter→11q23::1p31→1pter). Additionally, the proband's mother and brother were tested, resulting in the same exact translocation. In this study, we describe all possible meiotic segregations regarding this translocation, as well as the clinical phenotypes which could arise, if unbalanced products of conception survive. This is a rare case of familial complex chromosome rearrangement, giving a view for its reproductive consequences.

Abstract
We report on a 2-year-old boy with intellectual disabilities, distinctive facies, hypotonia, cardiac, and renal malformations. During his infancy he had recurrent episodes of apnea, cyanosis, and bradycardia. Chromosomal analysis showed a de novo apparently balanced translocation 46,XY,t(9;15)(q31;q26)dn. The use of array-comparative genomic hybridization (CGH) however, revealed the presence of additional cryptic complex chromosomal rearrangements involving a approximately 5-5.8 Mb distal duplication on chromosome 9 (9q34.1 --> 9q34.3), and deletions on three separate regions of chromosome 15 adding to approximately 8.1-12.2 Mb (15q21.2 --> 15q21.3, 15q22.31 --> 15q23, 15q25.1 --> 15q25.2). During confirmation with fluorescence in situ hybridization (FISH) an inversion was unexpectedly revealed on chromosome 15 (15q21.1 --> 15q21.2). To our knowledge this is the first patient reported whose phenotype is due to partial trisomy 9q, and complex interstitial deletions of 15q, not involving the Prader-Willi/Angelman region and encompassing the critical region 15q21q25. We provide correlation between the clinical findings of our patient and the phenotype of the 9q34 duplication syndrome, the 15q21, and the 15q25 deletion syndromes.

Abstract
We report on a 17-year-old female with numerous developmental abnormalities associated with 46,XX,dup(9)(q33.3q34.1), where the duplication occurred de novo. The patient presented with dysmorphic features and notable psychomotor delays, manifestations similar to those described in other reported cases of duplication of 9q34-qter. Due to late presentation and diagnosis, our patient was not evaluated and characterized until adolescence, when particular attention was paid to the development of secondary sexual characteristics, secondary amenorrhea and obesity.

Abstract
We report a case of a boy with a partial deletion of the long arm of chromosome 10 and partial duplication of the long arm of chromosome 9 due to maternal balanced translocation. The karyotype was 46,XY,-10, +der(10)t(9;10)(q32;q26)mat. Our patient had imperforate anus and as this finding is usually not observed in association with trisomy 9q, it suggests that partial monosomy of the long arm of chromosome 10 might be associated with anogenital anomalies.

Abstract
We report a case of an unbalanced cryptic telomeric translocation 46,XY,der(17),t(9;17)(q34.3;p13.3) in a boy with dysmorphic features and developmental delay. The proband had intrauterine growth retardation, postnatal short stature, and mild microcephaly. Magnetic resonance imaging showed incomplete myelination, but no evidence of lissencephaly. Cytogenetic analysis of the proband's peripheral blood showed an abnormal 17p. Fluorescence in situ hybridisation (FISH) with a Miller-Dieker cosmid probe did not detect a deletion for that area. Further analysis with a 17p telomere specific probe identified an unbalanced telomeric translocation. The same probe was used to determine the presence of an apparent balanced translocation t(9;17)(q34.3;p13.3) in the mother of the proband. The balanced translocation was confirmed with two cosmids that map distally on 9q34.3. Two phenotypically normal half sibs, a maternal aunt, a maternal uncle, and the maternal grandmother were found to be balanced translocation carriers as well. A subtle translocation carriers as well. A subtle translocation is one mechanism that can produce an abnormal phenotype in a patient who had a normal karyotype at lower band resolution levels.

Abstract
A complex chromosome rearrangement (CCR) involving chromosomes 7, 8, and 13 was detected in a phenotypically normal woman ascertained through her mentally retarded son with abnormal phenotype. He had a karyotype with 47 chromosomes including an extra der(13). In initial banding studies the CCR in the mother was interpreted as a three-way translocation. Fluorescence in situ hybridization with whole chromosome libraries and a telomere-specific probe was used to better characterize the rearrangement. Combined data allowed us to reinterpret the CCR as a translocation and an insertion. A review of 35 familial CCRs involving at least three chromosomes led to the following observations: 1) familial CCRs tend to have fewer chromosomes involved and fewer break-points than do de novo CCRs; 2) familial transmission is mainly observed through female carriers although the origin of de novo cases is paternal; 3) an apparent excess of balanced female carriers among the offspring of index carriers was noted; and 4) meiotic segregation resulting in malformed liveborn infants is most frequently due to adjacent-1 segregation, followed by 4:2 segregation; no adjacent-2 segregation was observed.

Abstract
Cytogenetic study of a 3-year-old girl with developmental delay and some minor abnormalities revealed a complex chromosome rearrangement (CCR) involving seven chromosomes with eight breakpoints, leading to monosomy of segment 5q15-q22. According to breakpoint distribution, CCRs may be classified as those with primary intrachromosomal abnormalities (including inversions, insertions, duplications, etc.) and those without them. Only the latter group of CCRs was used in this analysis. Comparison of theoretical and observed breakpoint distributions in 33 cases demonstrated that recurrent involvement of some chromosome(s) ("re-entry") occurs more frequently than expected. One possible explanation for this observation suggests that the initial event leads to an unstable provisional rearrangement, and subsequent breaks are necessary to stabilize the karyotype.

Abstract
We have studied an infant with multiple anomalies and a 46,XY,12p+ karyotype. Parental chromosomes were normal, and it was not possible to determine the identity of the extra material on chromosome 12 cytogenetically. Chromosome painting with probes from a chromosome 9 library identified this material as coming from chromosome 9, and cytogenetics established the duplication as 9q34-->qter. Comparison of this patient with others reported with partial dup(9q) documented excellent concordance of minor anomalies, most notably dolichocephaly, "deep-set" eyes, short horizontal palpebral fissures, beaked nose, micrognathia, arachnodactyly, and developmental delay. Identification of cytogenetically indeterminate abnormalities by molecular cytogenetics is very important, as it permits prognosis to be offered for families of newborn infants with unbalanced karyotypes.

Abstract
Structural abnormalities involving heterochromatic regions of the human genome are difficult to characterize because these segments are G-band negative by GTG technique, a routinely used procedure in clinical cytogenetic laboratories. Chromosome abnormalities of such cases have gone undetected or were incorrectly characterized because these regions are so-called heteromorphisms or variants. Consequently, much anxiety has been aroused by the confusion between a chromosome abnormality and a normal heteromorphic variant. We report the first documented case with a so-called highly unusual h region of chromosome 9 which is not a variation but a structural rearrangement involving a paracentric inversion and a duplication. The major clinical features were psychomotor retardation, microcephaly, narrow palpebral fissures, renal and genital anomalies, vertebral anomalies, protruding tongue, and learning and behavioral problems. A concise review of variable duplicated segments of 9q is also provided.

A girl with partial trisomy 9q is reported. She was characterized by dolichomorphism, abnormalities of the digits, a cardiac defect and craniofacial dysmorphism. A high-resolution analysis revealed the karyotype to be: 46,XX,-3,+ der(3)t(3;9)(q29;q13) de novo. A phenotype-karyotype correlation study in 22 cases of partial trisomies 9q supported the delineation of a trisomy 9q3 syndrome. The smallest region of overlap was confined to 9q32.
