Abstract
Partial trisomies are chromosome abnormalities resulting in a broad range of malformations depending on the size and location of the chromosomal rearrangement. Whereas diagnosis of these syndromes is usually made in early childhood, few descriptions exist about the clinical picture in adulthood. We report on a patient diagnosed at the age of 43 years with a 47,XY,+der(22)t(8;22)(q24.13;q11.21) karyotype and predominant clinical features of trisomy 8q. To our knowledge, this is the oldest patient described with a partial trisomy 8. The patient presented with moderate intellectual disability, a past history of epilepsy and facial anomalies. In addition, a large cell non-Hodgkin lymphoma was diagnosed in adulthood. Detailed breakpoint mapping by single nucleotide polymorphism (SNP) arrays showed that the derivative chromosome contains a full-length copy of the C-MYC oncogene. Given that trisomy 8q is the most frequent secondary chromosomal abnormality in hematological diseases, the possibility of a genetic predisposition for these disorders in patients with 8q duplication is raised.

Abstract
A derivative chromosome 8 was observed in a newborn boy who presented with low birth weight, multiple congenital anomalies, and dysmorphic face. The der(8) was further characterized at age 18 months by a high resolution G-banding analysis, spectral karyotyping, and fluorescence in situ hybridization (FISH) with multiple DNA probes. The karyotype was described as 46,XY,der(8)(qter-->q24.13::p21.3-->p23.3::p23.3-->qter), representing an inverted duplication of region 8p21.3-->p23.3 and a duplication of region 8q24.13-->qter, which attaches to the duplicated short arm segment at 8p21.3. Different from previously reported patients with an inverted duplication (8p), no deletion was detected in the distal region of 8p in this case. This young child had manifested a broad nasal bridge, micrognathia, cleft lip, hydrocephalus, partial agenesis of the corpus callosum, Dandy-Walker malformation, congenital heart defects, dysplastic kidneys, hydronephrosis, marked hypotonia, and significant psychomotor retardation. These features are compared with those commonly seen in cases with an inverted duplication of 8p and cases with a partial trisomy of 8q.

Abstract
We describe perinatal findings in a female fetus with partial trisomy 8q(8q24.1-->8qter) and partial monosomy 15q(15q26.1-->15qter) resulting from a paternal t(8;15) reciprocal translocation. Prenatal sonographic examination showed intra-uterine growth retardation, bilateral ventriculomegaly, cardiomegaly with arrhythmia, anhydramnios, and absent kidney and urinary bladder images. The pregnancy was terminated at 28 weeks of gestation. At birth, the infant manifested typical dysmorphic features of partial trisomy 8q. Necropsy further revealed hydrocephalus, congenital diaphragmatic hernia, ventricular septal defect, a horseshoe kidney with renal hypoplasia, and kyphoscoliosis. Our case shows that the coexistence of partial trisomy 8q24.1-->8qter and partial monosomy 15q26.1-->15qter are more detrimental than either defect alone and can result in a complex of major malformations. Prenatal ultrasound examination and cytogenetic assessment should be offered in subsequent pregnancies.

Abstract
We report on a folate sensitive fragile site at Xq27-28 in a girl with a multiple congenital anomalies and mental retardation syndrome, who also carries a duplication of the long arm of chromosome 8. The fragile site was shown by FISH to be distal to both FRAXA and FRAXE. DNA hybridisation with probe OxF14 showed the amplification of the CGG repeats of locus FRAXF in the patient and in her clinically normal mother.

Abstract
Trisomy 8 mosaicism is a relatively common autosomal chromosomal disorder characterized by features such as mental retardation, characteristic facies, skeletal abnormalities and congenital heart disease. The case of a 4-year-old boy is described with particular reference to the oro-facial manifestations, which included cleft palate, pronounced anterior open bite, complete reserved unilateral buccal cross-bite, slightly increased width of alveolar processes, and gingival enlargement.

Abstract
Partial trisomy 8qter-->q23 or q24.1 has been reported in 15 literature cases. We add two further case reports here. Patient 1 inherited the derivative (2) of a balanced maternal reciprocal translocation t(2;8)(qter;q2300) after 2:2 disjunction and adjacent-1 segregation, and is trisomic for the segment 8qter-->q2300. Patient 2 inherited a recombinant (8) of a balanced maternal inverted insertion inv ins(8)(q1300;q2300q24.2) and is trisomic for the segment 8q24.2-->q2300. The phenotype of both patients is described and compared to the spectrum of symptoms established from the 15 literature cases. This spectrum contains all features observed with a frequency of > = 50%. Patient 1 had 35% of the features of this spectrum; Patient 2 had 47%. The intrauterine survival probability of unbalanced offspring is assumed to be the same in both cases, as nearly the same segments are trisomic. The pedigrees indicate that the inversion carrier may have a reduced production probability of unbalanced gametes and therefore a reduced risk compared to the translocation carrier.

Abstract
Molecular cytogenetic techniques were used to delineate a subtle chromosome rearrangement in an infant with growth and psychomotor retardation, abnormal scalp hair pattern, narrow palpebral fissures, broad nasal bridge, bulbous nose, small nostrils, thin lips in a cupid's bow configuration, bilateral simian creases, and unilateral cryptorchidism. Analysis using GTG-banded chromosomes at about 400 band level showed no obvious abnormality. Prometaphase analysis at about 600 band level showed an extra band at 14q32 on GTG-banding. The father had the same extra band suggesting a reciprocal translocation but the second chromosome involved in the translocation could not be identified. High resolution replication banding on the father's lymphocytes showed a balanced reciprocal translocation 46,XY,rcp(8;14)(q24.1;q32.1). The translocation was confirmed by in situ hybridization with an immunoglobulin heavy chain probe which maps to 14q32.3. The infant therefore had duplication of 8q24.1----qter and deficiency of 14q32.1----qter. His phenotype resembled that of patients with partial duplications of the distal long arm of chromosome 8.

Abstract
Tetralogy of Fallot, the most common cyanotic heart defect, has not been closely associated with a specific chromosome defect. The San Luis Valley Recombinant Chromosome 8 [SLV Rec(8)] syndrome is strongly associated with congenital heart disease, particularly tetralogy of Fallot. This article reviews SLV Rec(8) syndrome and other chromosome 8 aberrations to suggest locations for cardiogenic genes. SLV Rec(8) [rec(8),dup q,inv(8)(p23q22)] syndrome has been found in Hispanic families in the southwestern United States. Congenital heart disease is found in 93.3% of SLV Rec(8) individuals (n = 45), with tetralogy of Fallot constituting 40.5% of all lesions and conotruncal defects, 55.6%. These frequencies exceed the incidence of tetralogy of Fallot (10%) and conotruncal defects (20%) among all children with heart defects (P less than 0.003 for both). Review of patients with deletion 8p (n = 13) showed heart defects in 84.6% with 27.3% being conotruncal defects. Among duplication 8q patients (n = 20), 45% had heart defects with conotruncal defects constituting 44%. Neither group differed significantly from expected in its incidence of conotruncal defects. Among patients with mosaic trisomy 8 (n = 47), 12 had heart abnormalities including one conotruncal defect. Among 3 patients with other rec(8) chromosomes, one had a ventricular septal defect. The cause of heart defects in SLV Rec(8) cannot be assigned to either the deletion of 8p or the duplication of 8q. The lack of an association between other chromosome 8 abnormalities and tetralogy of Fallot suggests that genes at the SLV Rec(8) breakpoints or an interaction between genes on both arms of chromosome 8 are important.

Abstract
On routine chromosome analysis a moderately retarded 18-year-old man was found to have an unusual short arm on one chromosome 14. With GTL-banding this chromosome showed an enlarged short arm with no evident secondary constriction. Negative CBG-banding of the short arm suggested the possibility of a translocation involving euchromatin. Interpretation of the abnormality as an unbalanced translocation relied on chromosome analysis using GTL-, CBG-, and Ag-NOR-banding of the proband's phenotypically normal mother, who was found to be carrying a balanced translocation involving chromosomes 8 and 14. In situ hybridization of sequences known to map to the short arm of chromosome 14 confirmed the interpretation and established that the breakpoint was within p11. The patient, whose karyotype is 46,XY, -14, +der(14)t(8;14)(q24.1;p11), is trisomic for the terminal end of the long arm of chromosome 8. The patient's clinical features are described and compared with those reported in patients trisomic for this region. This study demonstrates the importance of using a number of different banding techniques in conjunction with in situ hybridization for the investigation of morphologically unusual acrocentric short arm variants seen at routine diagnosis.
