Abstract
We present a complex chromosomal anomaly identified using cytogenetic and molecular methods. The child was diagnosed during the neonatal period with a multiple congenital anomalies syndrome characterized by: flattened occipital region; slight turricephaly; tall and broad forehead; hypertelorism; deep-set eyes; down slanting and short palpebral fissures; epicanthic folds; prominent nose with wide root and bulbous tip; microstomia; micro-retrognathia, large, short philtrum with prominent reliefs; low set, prominent ears; and congenital heart disease. The GTG banding karyotype showed a 46,XY,der(10)(10pter→10q26.2::4q26→4qter) chromosomal formula and his mother presented an apparently balanced reciprocal translocation: 46,XX,t(4;10)(q26;q26.2). The chromosomal anomalies of the child were confirmed by MLPA, and supplementary investigation discovered a quadruplication of the 4q35.2 region. The mother has a triplication of the same chromosomal fragment (4q35.2). Using array-CGH, we described the anomalies completely. Thus, the boy has a 71,057 kb triplication of the 4q26-q35.2 region, a 562 kb microdeletion in the 10q26.3 region, and a 795 kb quadruplication of the 4q35.2 region, while the mother presents a 795 kb triplication of the 4q35.2 region. Analyzing these data, we consider that the boy's phenotype is influenced only by the 4q partial trisomy. We compare our case with similar cases, and we review the literature data.

Prenatal diagnosis and molecular cytogenetic characterization of a small supernumerary marker chromosome (sSMC) inherited from her mosaic sSMC(15) mother and a literature review.

Abstract
OBJECTIVE We characterized a maternally inherited small supernumerary marker chromosome (sSMC) derived from chromosome 15 according to prenatal detection and made a review on the prenatal sSMC(15) cases with mosaic maternal inheritance. CASE REPORT A 29-year-old woman underwent amniocentesis at 19 weeks of gestation due to the high risk of Down syndrome in maternal serum screening. No abnormalities were observed in prenatal ultrasound findings. G-banding analysis revealed a karyotype of 47,XX,+mar. Subsequently, we recalled the couple back for chromosomal analysis. The father's karyotype was normal while the mother's karyotype was 47,XX,+mar[15]/46,XX[35]. Molecular genetic analysis was utilized to identify the marker chromosome. The chromosomal microarray analysis (CMA) results of the mother showed there existed microduplications in the locus of 14q32.33, 15q21.1, 19p12 and Xq26.2, respectively. Then Fluorescence in situ hybridization (FISH) using specific probes for chromosomes 13/21, 14/22, and 15 was applied on the mother and the fetus. And the marker chromosomes for the mother and the fetus were all finally identified as inv dup(15) (D15Z1++, SNRPN-, PML-), which illustrated that the fetus inherited the sSMC(15) from her mother. Finally, a healthy female infant was delivered with no phenotypic abnormalities at 39 weeks. CONCLUSION The combined utilization of the molecular genetic technologies, such as FISH and CMA, plays a critical role in the identification of the origins and genetic constitutions of sSMC, which would make a significant contribution to genetic counseling and prenatal diagnosis.

Molecular characterization of small supernumerary marker chromosomes derived from chromosome 14/22 detected in adult women with fertility problems: Three case reports and literature review.

Abstract
RATIONALE Small supernumerary marker chromosomes (sSMC) are structurally abnormal chromosomes, which can be detected in patients with developmental retardation, infertile problems, and prenatal fetus. We report 3 adult female with fertility problems carrying sSMC(14/22) and aim to explore the correlation between sSMC(14/22) and fertility problems in women. PATIENT CONCERNS Three Chinese female patients were referred for infertility consultation in our hospital. DIAGNOSES The karyotype of these 3 patients were 47, XX, +mar. The chromosome microarray analysis (CMA) detected various chromosomal duplications and deletions in the 3 cases: a 0.49Mb gain of 5q32 for case 1; a 0.54Mb gain of 14q32.33 and a 1.83Mb gain of 16p11.2 for case 2; a 0.37Mb loss of 13q21.2q21.31 and a 0.12Mb gain of Xp11.2 for case 3. Fluorescence in situ hybridization (FISH) using the specific probes for chromosomes 13/21, 14/22, and 15 was applied to identify the origination of these sSMC, which were all finally identified as sSMC(14/22). INTERVENTIONS Case 1 underwent the artificial reproductive technology to get her offspring and finally delivered a healthy male infant at 39 weeks. Case 2 did not plan to choose in vitro fertilization (IVF) to get offspring. Case 3 refused to do assisted reproductive technology. OUTCOMES The genotype-phenotype correlation of sSMC(14/22) remain unclear. However, the existence of sSMC(14/22) might negatively affect the fertility ability in sSMC female carriers. LESSONS The combined application of traditional banding technique and molecular cytogenetic techniques can better identify more details of sSMC. For sSMC carriers with fertility problems, they could get their offsprings through assisted reproductive technologies after comprehensive fertility assessment.
