Abstract
Chromoanagenesis is a cellular mechanism that leads to complex chromosomal rearrangements (CCR) during a single catastrophic event. It may result in loss and/or gain of genetic material and may be responsible for various phenotypes. These rearrangements are usually sporadic. However, some familial cases have been reported. Here, we studied six families in whom an asymptomatic or paucisymptomatic parent transmitted a CCR to its offspring in an unbalanced manner. The rearrangements were characterized by karyotyping, fluorescent in situ hybridization, chromosomal microarray (CMA) and/or whole genome sequencing (WGS) in the carrier parents and offspring. We then hypothesized meiosis-pairing figures between normal and abnormal parental chromosomes that may have led to the formation of new unbalanced rearrangements through meiotic recombination. Our work indicates that chromoanagenesis might be associated with a normal phenotype and normal fertility, even in males, and that WGS may be the only way to identify these events when there is no imbalance. Subsequently, the CCR can be transmitted to the next generation in an unbalanced and unpredictable manner following meiotic recombination. Thereby, prenatal diagnosis using CMA should be proposed to these families to detect any pathogenic imbalances in the offspring.

Abstract
Background Individuals with various sized terminal duplications of chromosome 5p or terminal deletions of chromosome 18q have been described. These aberrations may cause congenital malformations and intellectual disability of varying severity. Methods Via an international collaborative effort, we obtained a cytogenetic diagnosis for a 5‐year‐old boy of Afro‐Caribbean ancestry who has global developmental delay, dysmorphology, hypotonia, feeding difficulties, bilateral club feet, and intellectual disability. Results Conventional G‐banded karyotyping showed additional chromatin of unknown origin on the long arm of chromosome 18. SNP microarray confirmed the loss of ~6.4 Mb from chromosome 18q: arr[hg19] 18q22.3‐q23(71,518,518‐77,943,115)x1. The source of the additional chromatin was determined from the microarray to be ~32 Mb from the short arm of chromosome 5 (arr[hg19] 5p13.3‐p15.33(51,045‐32,062,984)x3). The unbalanced translocation was verified by fluorescent in situ hybridization (FISH). Both parents are healthy and have normal karyotypes suggesting that this abnormality arose de novo in the proband, although gonadal mosaicism in a parent cannot be excluded. Conclusion The combination of clinical features in this individual is most likely due to the partial deletion of 18q and partial duplication of 5p, which to our knowledge has not been previously described.

Abstract
Duplication of the distal 1q and 4p segments are both characterized by the presence of intellectual disability/neurodevelopmental delay and dysmorphisms. Here, we describe a male with a complex chromosome rearrangement (CCR) presenting with overlapping clinical findings between these 2 syndromes. In order to better characterize this CCR, classical karyotyping, FISH, and chromosomal microarray analysis were performed on material from the patient and his parents, which revealed an unbalanced karyotype with duplications at 1q41q43 and 4p15.2p14 in the proband. The rearrangements, which were derived from a maternal balanced karyotype, included an insertion of a segment from the long to the short arm of chromosome 1, a balanced translocation involving chromosomes 14 and 18, and an insertion of a segment from the short arm of chromosome 4 into the derived chromosome 14. This study aimed to better define the clinical history and prognosis of a patient with this rare category of chromosomal aberration. Our results suggest that the frequency of CCR in the general population may be underestimated; when balanced, they may not have a phenotypic effect. Moreover, they emphasize the need for cytogenetic techniques complementary to chromosomal microarray for proper genetic counseling.

Abstract
Silver-Russell syndrome (SRS) is a rare genetic condition primarily characterized by growth restriction and facial dysmorphisms. While hypomethylation of H19/IGF2:IG-DMR (imprinting control region 1 [IC1]) located at 11p15.5 and maternal uniparental disomy of chromosome 7 (upd[7]mat) are the most common genetic mechanisms responsible for SRS, the expanding body of literature describing alternative causative variants suggests SRS is a highly heterogeneous condition, also involving variation in the HMGA2-PLAG1-IGF2 pathway. We report a familial PLAG1 deletion in association with a complex chromosomal rearrangement. We describe two siblings with differing unbalanced chromosomal rearrangements inherited from a mother with a 5-breakpoint balanced complex rearrangement involving chromosomes 2, 8, and 21. The overlapping but diverse phenotypes in the siblings were characterized by shared SRS-like features, underlined by a PLAG1 whole gene deletion. Genetic analysis and interpretation was further complicated by a meiotic recombination event occurring in one of the siblings. This family adds to the limited literature available on PLAG1-related SRS. We have reviewed all currently known cases aiming to define the associated phenotype and guide future genetic testing strategies. The heterogeneity of SRS is further expanded by the involvement of complex cytogenomic abnormalities, imposing requirements for a comprehensive approach to testing and genetic counseling.

Abstract
Chromosomal microarray analyses (CMA) have greatly increased both the yield and diagnostic accuracy of postnatal analysis; it has been used as a first-tier cytogenetic test in patients with intellectual disability, autism spectrum disorder, and multiple congenital abnormalities. During the last 15 years, we performed CMA in approximately 8,000 patients with neurodevelopmental and/or congenital disorders, of which 13 (0.16%) genetically catastrophic complex chromosomal rearrangements were identified. These ultrarare rearrangements showed clustering of breakpoints, characteristic of chromoanagenesis events. Al1 13 complex events display underlying formation mechanisms, originating either by a synchronization of the shattering of clustered chromosome regions in which regional asynchrony of DNA replication may be one of the main causes of disruption. We provide an overview of the copy number profiling in these patients. Although several previous studies have suggested that chromoanagenesis is often a genetic disease source in postnatal diagnostic screening, due to either the challenge of clinical interpretation of these complex rearrangements or the limitation of microarray resolution relative to the small size and complexity of chromogenic induced chromosome abnormalities, bringing further attention and to study its occurrence in the clinical setting is extremely important.

Abstract
Structural aberrations involving more than two breakpoints on two or more chromosomes are known as complex chromosomal rearrangements (CCRs). They can reduce fertility through gametogenesis arrest developed due to disrupted chromosomal pairing in the pachytene stage. We present a familial case of two infertile brothers (with azoospermia and cryptozoospermia) and their mother, carriers of an exceptional type of CCR involving chromosomes 1 and 7 and three breakpoints. The aim was to identify whether meiotic disruption was caused by CCR and/or genomic mutations. Additionally, we performed a literature survey for male CCR carriers with reproductive failures. The characterization of the CCR chromosomes and potential genomic aberrations was performed using: G-banding using trypsin and Giemsa staining (GTG banding), fluorescent in situ hybridization (FISH) (including multicolor FISH (mFISH) and bacterial artificial chromosome (BAC)-FISH), and genome-wide array comparative genomic hybridization (aCGH). The CCR description was established as: der(1)(1qter->1q42.3::1p21->1q42.3::7p14.3->7pter), der(7)(1pter->1p2 1::7p14.3->7qter). aCGH revealed three rare genes variants: ASMT, GARNL3, and SESTD1, which were ruled out due to unlikely biological functions. The aCGH analysis of three breakpoint CCR regions did not reveal copy number variations (CNVs) with biologically plausible genes. Synaptonemal complex evaluation (brother-1; spermatocytes II/oligobiopsy; the silver staining technique) showed incomplete conjugation of the chromosomes. Associations between CCR and the sex chromosomes (by FISH) were not found. A meiotic segregation pattern (brother-2; ejaculated spermatozoa; FISH) revealed 29.21% genetically normal/balanced spermatozoa. The aCGH analysis could not detect smaller intergenic CNVs of few kb or smaller (indels of single exons or few nucleotides). Since chromosomal aberrations frequently do not affect the phenotype of the carrier, in contrast to the negative influence on spermatogenesis, there is an obvious need for genomic sequencing to investigate the point mutations that may be responsible for the differences between the azoospermic and cryptozoospermic phenotypes observed in a family. Progeny from the same parents provide a unique opportunity to discover a novel genomic background of male infertility.

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
Chromosomal rearrangements have long been known to significantly impact fertility and miscarriage risk. Advancements in molecular diagnostics are challenging contemporary clinicians and patients in accurately characterizing the reproductive risk of a given abnormality. Initial attempts at preimplantation genetic diagnosis were limited by the inability to simultaneously evaluate aneuploidy and missed up to 70% of aneuploidy in chromosomes unrelated to the rearrangement. Contemporary platforms are more accurate and less susceptible to technical errors. These techniques also offer the ability to improve outcomes through diagnosis of uniparental disomy and may soon be able to consistently distinguish between normal and balanced translocation karyotypes. Although an accurate projection of the anticipated number of unbalanced embryos is not possible at present, confirmation of normal/balanced status results in high pregnancy rates (PRs) and diagnostic accuracy.

Abstract
Complex chromosome rearrangements (CCRs) are currently defined as structural genome variations that involve more than 2 chromosome breaks and result in exchanges of chromosomal segments. They are thought to be extremely rare, but their detection rate is rising because of improvements in molecular cytogenetic technology. Their population frequency is also underestimated, since many CCRs may not elicit a phenotypic effect. CCRs may be the result of fork stalling and template switching, microhomology-mediated break-induced repair, breakage-fusion-bridge cycles, or chromothripsis. Patients with chromosomal instability syndromes show elevated rates of CCRs due to impaired DNA double-strand break responses during meiosis. Therefore, the putative functions of the proteins encoded by ATM, BLM, WRN, ATR, MRE11, NBS1, and RAD51 in preventing CCRs are discussed. CCRs may exert a pathogenic effect by either (1) gene dosage-dependent mechanisms, e.g. haploinsufficiency, (2) mechanisms based on disruption of the genomic architecture, such that genes, parts of genes or regulatory elements are truncated, fused or relocated and thus their interactions disturbed - these mechanisms will predominantly affect gene expression - or (3) mixed mutation mechanisms in which a CCR on one chromosome is combined with a different type of mutation on the other chromosome. Such inferred mechanisms of pathogenicity need corroboration by mRNA sequencing. Also, future studies with in vitro models, such as inducible pluripotent stem cells from patients with CCRs, and transgenic model organisms should substantiate current inferences regarding putative pathogenic effects of CCRs. The ramifications of the growing body of information on CCRs for clinical and experimental genetics and future treatment modalities are briefly illustrated with 2 cases, one of which suggests KDM4C (JMJD2C) as a novel candidate gene for mental retardation.

Abstract
Small insertions and deletions (indels) and large structural variations (SVs) are major contributors to human genetic diversity and disease. However, mutation rates and characteristics of de novo indels and SVs in the general population have remained largely unexplored. We report 332 validated de novo structural changes identified in whole genomes of 250 families, including complex indels, retrotransposon insertions, and interchromosomal events. These data indicate a mutation rate of 2.94 indels (1-20 bp) and 0.16 SVs (>20 bp) per generation. De novo structural changes affect on average 4.1 kbp of genomic sequence and 29 coding bases per generation, which is 91 and 52 times more nucleotides than de novo substitutions, respectively. This contrasts with the equal genomic footprint of inherited SVs and substitutions. An excess of structural changes originated on paternal haplotypes. Additionally, we observed a nonuniform distribution of de novo SVs across offspring. These results reveal the importance of different mutational mechanisms to changes in human genome structure across generations.

Abstract
Chromothripsis represents an extreme class of complex chromosome rearrangements (CCRs) with major effects on chromosomal architecture. Although recent studies have associated chromothripsis with congenital abnormalities, the incidence and pathogenic effects of this phenomenon require further investigation. Here, we analyzed the genomes of three families in which chromothripsis rearrangements were transmitted from a mother to her child. The chromothripsis in the mothers resulted in completely balanced rearrangements involving 8-23 breakpoint junctions across three to five chromosomes. Two mothers did not show any phenotypic abnormalities, although 3-13 protein-coding genes were affected by breakpoints. Unbalanced but stable transmission of a subset of the derivative chromosomes caused apparently de novo complex copy-number changes in two children. This resulted in gene-dosage changes, which are probably responsible for the severe congenital phenotypes of these two children. In contrast, the third child, who has a severe congenital disease, harbored all three chromothripsis chromosomes from his healthy mother, but one of the chromosomes acquired de novo rearrangements leading to copy-number changes. These results show that the human genome can tolerate extreme reshuffling of chromosomal architecture, including breakage of multiple protein-coding genes, without noticeable phenotypic effects. The presence of chromothripsis in healthy individuals affects reproduction and is expected to substantially increase the risk of miscarriages, abortions, and severe congenital disease.

Abstract
We report an exceptional complex chromosomal rearrangement (CCR) found in three individuals in a family that involves 4 chromosomes with 5 breakpoints. The CCR was ascertained in a phenotypically abnormal newborn with additional chromosomal material on the short arm of chromosome 4. Maternal karyotyping indicated that the mother carried an apparently balanced CCR involving chromosomes 4, 6, 11, and 18. Maternal transmission of the derivative chromosome 4 resulted in partial trisomy for chromosomes 6q and 18q and a partial monosomy of chromosome 4p in the proband. Further family studies found that the maternal grandmother carried the same apparently balanced CCR as the proband's mother, which was confirmed using the whole chromosome painting (WCP) FISH. High resolution whole genome microarray analysis of DNA from the proband's mother found no evidence for copy number imbalance in the vicinity of the CCR translocation breakpoints, or elsewhere in the genome, providing evidence that the mother's and grandmother's CCRs were balanced at a molecular level. This structural rearrangement can be categorized as an exceptional CCR due to its complexity and is a rare example of an exceptional CCR being transmitted in balanced and/or unbalanced form across three generations.

Abstract
Complex chromosomal rearrangements (CCRs) are balanced or unbalanced structural rearrangements involving three or more cytogenetic breakpoints on two or more chromosomal pairs. The phenotypic anomalies in such cases are attributed to gene disruption, superimposed cryptic imbalances in the genome, and/or position effects. We report a 14-year-old girl who presented with multiple congenital anomalies and developmental delay. Chromosome and FISH analysis indicated a highly complex chromosomal rearrangement involving three chromosomes (3, 7 and 12), seven breakpoints as a result of one inversion, two insertions, and two translocations forming three derivative chromosomes. Additionally, chromosomal microarray study (CMA) revealed two submicroscopic deletions at 3p12.3 (467 kb) and 12q13.12 (442 kb). We postulate that microdeletion within the ROBO1 gene at 3p12.3 may have played a role in the patient’s developmental delay, since it has potential activity-dependent role in neurons. Additionally, factors other than genomic deletions such as loss of function or position effects may also contribute to the abnormal phenotype in our patient.

Abstract
Complex chromosome rearrangements (CCRs) are structurally balanced or unbalanced aberrations involving more than two breakpoints on two or more chromosomes. CCRs can be a potential reason for genomic imbalance in gametes, which leads to a drastic reduction in fertility. In this study, the meiotic segregation pattern, aneuploidy of seven chromosomes uninvolved in the CCR and chromatin integrity were analysed in the ejaculated spermatozoa of a 46,XY,t(6;10;11)(q25.1;q24.3;q23.1)mat carrier with asthenozoospermia and a lack of conception. The frequency of genetically unbalanced spermatozoa was 78.8% with a prevalence of 4:2 segregants of 38.2%, while the prevalence of the adjacent 3:3 mode was 35.3%. Analysis of the aneuploidy of chromosomes 13, 15, 18, 21, 22, X and Y revealed an approximately fivefold increased level in comparison with that of the control group, indicating the presence of an interchromosomal effect. Sperm chromatin integrity status was evaluated using chromomycin A3 and aniline blue staining (deprotamination), acridine orange test and TUNEL assay (sperm DNA fragmentation). No differences were found when comparisons were made with a control group. We suggest that the accumulation of genetically unbalanced spermatozoa, significantly increased sperm aneuploidy level and decreased sperm motility (20%, progressive) were not responsible for the observed lack of reproductive success in the analysed infertile t(6;10;11) carrier. Interestingly, in the case described herein, a high level of sperm chromosomal imbalance appears not to be linked to sperm chromatin integrity status.

Abstract
Next-generation mate-pair sequencing (MPS) has revealed that many constitutional complex chromosomal rearrangements (CCRs) are associated with local shattering of chromosomal regions (chromothripsis). Although MPS promises to identify the molecular basis of the abnormal phenotypes associated with many CCRs, none of the reported mate-pair sequenced complex rearrangements have been simultaneously studied with state-of-the art molecular cytogenetic techniques. Here, we studied chromothripsis-associated CCR involving chromosomes 2, 5 and 7, associated with global developmental and psychomotor delay and severe speech disorder. We identified three truncated genes: CDH12, DGKB and FOXP2, confirming the role of FOXP2 in severe speech disorder, and suggestive roles of CDH12 and/or DGKB for the global developmental and psychomotor delay. Our study confirmes the power of MPS for detecting breakpoints and truncated genes at near nucleotide resolution in chromothripsis. However, only by combining MPS data with conventional G-banding and extensive fluorescence in situ hybridizations could we delineate the precise structure of the derivative chromosomes.

Abstract
Constitutional complex chromosomal rearrangements (CCRs) are considered rare cytogenetic events. Most apparently balanced CCRs are de novo and are usually found in patients with abnormal phenotypes. High-resolution techniques are unveiling genomic imbalances in a great percentage of these cases. In this paper, we report a patient with growth and developmental delay, dysmorphic features, nervous system anomalies (pachygyria, hypoplasia of the corpus callosum and cerebellum), a marked reduction in the ossification of the cranial vault, skull base sclerosis, and cardiopathy who presents a CCR with 9 breakpoints involving 4 chromosomes (3, 6, 8 and 14) and a 0.6-Mb deletion in 14q24.1. Although the only genomic imbalance revealed by the array technique was a deletion, the clinical phenotype of the patient most likely cannot be attributed exclusively to haploinsufficiency. Other events must also be considered, including the disruption of critical genes and position effects. A combination of several different investigative approaches (G-banding, FISH with different probes and SNP array techniques) was required to describe this CCR in full, suggesting that CCRs may be more frequent than initially thought. Additionally, we propose that a chain chromosome breakage mechanism may have occurred as a single rearrangement event resulting in this CCR. This study demonstrates the importance of applying different cytogenetic and molecular techniques to detect subtle rearrangements and to delineate the rearrangements at a more accurate level, providing a better understanding of the mechanisms involved in CCR formation and a better correlation with phenotype.

Abstract
Genomic rearrangements may give rise to congenital disease and contribute to cancer development. Recent evidence has shown that very complex genomic rearrangements in cancer cells can result from a single catastrophic event of massive DNA breakage and repair, termed chromothripsis. This results in heavily rearranged chromosomes comprising frequent sequence losses. A very similar process of chromosome shattering is found for complex chromosome rearrangements in the germline of patients with congenital disorders. Here, we review the literature on chromothripsis in cancer and congenital disease. We describe differences and similarities for chromothripsis rearrangements in somatic tissue and the germ line and we discuss the cellular origin and molecular mechanisms of chromothripsis.

Abstract
BACKGROUNDS While XXY aneuploidy is the most common disorder of sex chromosomes in men, complex chromosomal rearrangements (CCRs) are rare in humans. CASE DESCRIPTION Here we describe clinical and cytogenetic findings in a male referred to our cytogenetic laboratory by an infertility clinic. The patient's age was 35 at the time of referral. Total azoospermia was confirmed on semen analysis. RESULTS The karyotype of peripheral blood showed 47,XXY,t(1;3;5)(p22;q29;q22). The mother had the same CCRs. DISCUSSION To our best of our knowledge this is the first case of 47,XXY with CCRs. We think it is important to report such a unique chromosomal occurrence.

Abstract
Complex genomic rearrangements (CGRs) consisting of two or more breakpoint junctions have been observed in genomic disorders. Recently, a chromosome catastrophe phenomenon termed chromothripsis, in which numerous genomic rearrangements are apparently acquired in one single catastrophic event, was described in multiple cancers. Here, we show that constitutionally acquired CGRs share similarities with cancer chromothripsis. In the 17 CGR cases investigated, we observed localization and multiple copy number changes including deletions, duplications, and/or triplications, as well as extensive translocations and inversions. Genomic rearrangements involved varied in size and complexities; in one case, array comparative genomic hybridization revealed 18 copy number changes. Breakpoint sequencing identified characteristic features, including small templated insertions at breakpoints and microhomology at breakpoint junctions, which have been attributed to replicative processes. The resemblance between CGR and chromothripsis suggests similar mechanistic underpinnings. Such chromosome catastrophic events appear to reflect basic DNA metabolism operative throughout an organism's life cycle.

Abstract
Complex chromosome rearrangements are constitutional structural rearrangements involving three or more chromosomes or having more than two breakpoints. These are rarely seen in the general population but their frequency should be much higher due to balanced states with no phenotypic presentation. These abnormalities preferentially occur de novo during spermatogenesis and are transmitted in families through oogenesis.Here, we report a de novo complex chromosome rearrangement that interests eight chromosomes in eighteen-year-old boy with an abnormal phenotype consisting in moderate developmental delay, cleft palate, and facial dysmorphisms.Standard G-banding revealed four apparently balanced translocations [corrected] involving the chromosomes 1;13, 3;19, 9;15 and 14;18 that appeared to be reciprocal. Array-based comparative genomic hybridization analysis showed no imbalances at all the breakpoints observed except for an interstitial microdeletion on chromosome 15. This deletion is 1.6 Mb in size and is located at chromosome band 15q14, distal to the Prader-Willi/Angelman region. Comparing the features of our patient with published reports of patients with 15q14 deletion this finding corresponds to the smallest genomic region of overlap. The deleted segment at 15q14 was investigated for gene content.

Abstract
Complex chromosomal rearrangements (CCRs) are uncommon and mainly occur de novo. We report here on a familial CCR involving chromosomes 2, 6, and 18. The propositus is a boy first referred because of growth delays, hypotonia, and facial anomalies, suggestive of deletion 18q syndrome. However, a cytogenetic family study disclosed a balanced CCR in three generations, which was detailed by FISH using BAC clones, and consisted of eight breakpoints with five insertional translocations (ITs). The propositus had a cryptic 18q deletion and a 6p duplication. Paternal transmission of this CCR was observed through three generations without meiotic recombination. Our investigation allowed us to provide porosities counseling and management of prenatal diagnosis for propositus cousin who carries this particular CCR.

Abstract
A balanced complex chromosome rearrangement (CCR) involving three chromosomes is rare and may lead to different types of aneuploid germ cells. We report here a 14-year follow-up of a boy with a karyotype defined as 46,XY,der(18)t(6;13;18)(q21;q21.32;q22.3).ish der(18)(13qter+,18qter-) characterized by multiple congenital abnormalities, including distinctive minor facial anomalies, short neck, abnormalities of the extremities, anogenital abnormalities, flexion contractures, especially at extremities, and severe mental and growth retardation. Chromosome analysis in the mother showed a CCR involving chromosomes 6, 13, and 18. This CCR was the result of a three-break rearrangement, and the derivative chromosome 13 consisted of parts of chromosomes 18 and 13. The karyotype of the child was not balanced, and resulted in partial trisomy for 13q and partial monosomy for 18q detected prenatally by conventional and molecular cytogenetics. Although such a karyotype and its phenotype have not previously been reported, we have compared the clinical and cytogenetic data from our patient with previously described cases of partial trisomy 13q and monosomy 18q despite different break points. We are presenting a new CCR in a woman with normal phenotype with a history of four early abortions and a long follow-up of her malformed newborn with partial 13q trisomy and 18q monosomy.

Abstract
BACKGROUND Complex chromosomal rearrangements (CCR) are rare cytogenetic findings that are difficult to karyotype by conventional cytogenetic analysis partially because of the relative low resolution of this technique. High resolution genotyping is necessary in order to identify cryptic imbalances, for instance near the multiple breakpoints, to explain the abnormal phenotype in these patients. We applied several molecular techniques to elucidate the complexity of the CCRs of two adult patients with abnormal phenotypes. RESULTS Multicolour fluorescence in situ hybridization (M-FISH) showed that in patient 1 the chromosomes 1, 10, 15 and 18 were involved in the rearrangement whereas for patient 2 the chromosomes 5, 9, 11 and 13 were involved. A 250 k Nsp1 SNP-array analysis uncovered a deletion in chromosome region 10p13 for patient 1, harbouring 17 genes, while patient 2 showed no pathogenic gains or losses. Additional FISH analysis with locus specific BAC-probes was performed, leading to the identification of cryptic interstitial structural rearrangements in both patients. CONCLUSION Application of M-FISH and SNP-array analysis to apparently balanced CCRs is useful to delineate the complex chromosomal rearrangement in detail. However, it does not always identify cryptic imbalances as an explanation for the abnormal phenotype in patients with a CCR.

Abstract
Copy number variation (CNV) is a major source of genetic variation among humans. In addition to existing as benign polymorphisms, CNVs can also convey clinical phenotypes, including genomic disorders, sporadic diseases and complex human traits. CNV results from genomic rearrangements that can represent simple deletion or duplication of a genomic segment, or be more complex. Complex chromosomal rearrangements (CCRs) have been known for some time but their mechanisms have remained elusive. Recent technology advances and high-resolution human genome analyses have revealed that complex genomic rearrangements can account for a large fraction of non-recurrent rearrangements at a given locus. Various mechanisms, most of which are DNA-replication-based, for example fork stalling and template switching (FoSTeS) and microhomology-mediated break-induced replication (MMBIR), have been proposed for generating such complex genomic rearrangements and are probably responsible for CCR.

INTERVENTION(S) Balanced or normal embryos were diagnosed by PGD and transferred. MAIN OUTCOME MEASURE(S) Diagnosis rate of FISH, pregnancy outcome, and karyotype of amniocentesis. RESULT(S) Blastomeres were biopsied from 56 embryos in four PGD cycles, and 54 embryos (96.4%) were successfully diagnosed by FISH. Among them, four embryos were diagnosed as transferable in two cycles of patient B and one cycle of patient C. After three cycles of embryo transfer, a pregnancy was achieved in the second PGD cycle of patient B, and the karyotype of amniocentesis was 46,XY,t(2;18)(q14.1;q21). A healthy baby was delivered at 40 weeks of gestation by cesarean section. CONCLUSION(S) This is the first report for a live birth after PGD in the CCR carriers associated with translocation and deletion, 46,X,del(X)(p22.3),t(2;18)(q14.1;q21)[48]/45,X,t(2;18)(q14.1;q21)[12]. Preimplantation genetic diagnosis for CCRs needs more consideration and advanced techniques for full karyotyping.

Abstract
OBJECTIVE To describe a de novo complex chromosome rearrangement(CCR) detected prenatally and studied afterbirth. METHODS Conventional cytogenetics and fluorescent in situ hybridization (FISH) were performed on amniotic fluid and peripheral blood. High-resolution comparative genomic hybridization (HR-CGH) analysis was made postnatally. RESULTS Prenatal/postnatal cytogenetic, FISH and HR-CGH analyses revealed an apparently balanced de novo CCR ascertained as 46,XY,t(2; 3;9)(q21;p24;q22),der(5)inv(5)(?p11q13)t(5; 11)(?p13;q25),ins(5; 3)(?p13;?p23p24). At 9 months,the child has neither congenital anomalies nor evidence of delayed psychomotor development. CONCLUSIONS Our report describes a rare CCR detected prenatally and shows the usefulness of FISH and CGH in complementing conventional cytogenetics.

Abstract
Complex chromosomal rearrangements (CCRs) are rare events in human pathology and are usually considered to induce severe reproductive impairment by disturbing the meiotic process and producing unbalanced gametes responsible for high reproductive risk. One-third of all CCRs are familial and tend to implicate fewer breakpoints and fewer chromosomes than de novo cases. CCRs are rarely transmitted through spermatogenesis and are primarily ascertained by male infertility. We report a familial balanced CCR, with seven breakpoints involving three chromosomes, which was detected prenatally in a female fetus conceived after intracytoplasmic sperm injection (ICSI) in a couple initially thought to be a carrier of a paternal reciprocal translocation involving two chromosomal breakpoints. Fluorescent in-situ hybridization (FISH) was used to elucidate the complexity of this CCR. The karyotype of the female CCR carrier was balanced and determined as 46,XX.ish t(1;4)(q42;q32)(WCP1+, D1Z5+, WCP4+, D1S3738-, D4S2930+; WCP4+, D4Z1+, WCP1+, D4S2930-, D1S3738+), ins(1;11)(q41;q23q24)(WCP1+,WCP11+, D11S2071-, MLL+; WCP11+, D11S2071+, WCP1-, MLL-), ins(4;11)(q23;q14q23)(WCP4+,WCP11+; WCP11+,WCP4-). The same balanced CCR was confirmed in her oligozoospermic father. We report, to our knowledge, the first case of ICSI performed in an infertile male with CCR, resulting in a balanced CCR carrier female with a normal clinical follow-up at 4 years of age. This particular case stresses the point of the relevance and feasibility of ICSI procedure in cases of balanced CCRs.

Abstract
Complex chromosomal rearrangements, defined as exchanges between three or more chromosomes, are very rare aberrations in human chromosomal pathology. We present a case of a complex, apparently balanced maternal chromosome rearrangement involving five different chromosomes (1, 4, 10, 12 and 20) and six breakpoints ascertained through a deletion of the short arm of chromosome 4 [del(4)(p14p15)] detected in a mother's affected 2-year old daughter.

Abstract
Complex chromosomal rearrangement (CCR) is a structural abnormality of chromosomes that rarely appears in individuals with normal phenotypes. A CCR involving chromosomes 9, 13, and 22 was ascertained in a phenotypically normal woman through a neonate with multiple congenital malformations and partial trisomies of 13 and 22. We diagnosed the CCR using high-resolution chromosome analysis and three-color fluorescence in situ hybridization (three-color FISH) analysis, and ascertained a balanced CCR without cryptic imbalances using array comparative genomic hybridization (array CGH) and FISH. In the present work, we report on the case together with a literature review.

Abstract
Complex chromosome rearrangements (CCR) are rare structural chromosome aberrations that can be found in patients with phenotypic abnormalities or in phenotypically normal patients presenting, however, recurrent miscarriages or infertility. Conventional karyotype generally allows their identification. However, molecular cytogenetic methods can reveal subtle rearrangements. We report, here, the identification of an unbalanced maternally inherited CCR in a boy with multiple congenital malformations and delayed development. High-resolution karyotype completed by molecular cytogenetic prompted us to precise the rearrangements. The healthy mother was found to carry a balanced de novo CCR that implicates four chromosomes (8, 10, 11 and 16), six breakpoints, three translocations and an insertion. The malsegregation of this CCR had led, in her son, to partial 10p12.3 to 10p14 deletion, a chromosomal region associated with the DiGeorge like phenotype.
