Abstract
Objective High-throughput sequencing based on copy number variation (CNV-seq) is
commonly used to detect chromosomal abnormalities including aneuploidy. This
study provides evidence for the prevalence of chromosomal abnormalities in
target populations. Methods A total of 160 samples, including 83 high-risk pregnancies, 37 spontaneous
abortions, and 40 suspected genetic disorders, were analyzed by CNV-seq.
Relationships between the incidence of these chromosomal abnormalities and
risk factors (e.g. advanced maternal age, abnormal pregnancy history, and
family history of congenital disease) were further analyzed by subgroup. Results A total of 37 (44.6%) high-risk pregnancies, 25 (67.6%) spontaneous
abortions, and 22 (55%) suspected genetic disorders had chromosomal
abnormalities including aneuploidy and CNVs. There was an increased risk
association between the prevalence of aneuploidy and pathogenic-relevant CNV
in the fetus or abortive tissue and advanced maternal age. Moreover, a
family history of congenital disease was also positively correlated with
fetal chromosomal abnormalities in high-risk pregnancies. Conclusion A relatively high prevalence of chromosomal abnormalities was detected in
high-risk pregnancies, spontaneous abortions, and suspected genetic
disorders, indicating the importance of CNV detection in such
populations.

Abstract
Prenatal diagnosis focuses on the detection of anatomic and physiologic problems with a foetus before birth. Karyotyping is currently considered the gold standard for prenatal diagnosis of chromosomal abnormalities, but this method can be time consuming. This study evaluated the diagnostic accuracy of the BACs-on-BeadsTM (BoBs™) assay for the rapid diagnosis of aneuploidies and microdeletions. A total of 625 samples from pregnant women in Fujian province, in southeastern China-including three chorionic villus biopsies, 523 amniotic fluid samples, and 99 umbilical-cord centesis samples-were assessed for chromosomal abnormalities by karyotyping and by the BoBs™ assay. A diagnosis was successfully achieved by karyotyping for 98.8% (618/625) and by the BoBs™ assay for 100% (625/625) of the samples. Both assays were concordant for trisomy 21 (2.72%, 17/625), trisomy 18 (1.12%, 7/625), trisomy 13 (0.48%, 3/625), and sex chromosome aneuploidies (0.8%, 5/625). Unlike karyotyping, the BoBs™ assay detected 22q11.2 microdeletion (0.64%, 4/625), 22q11.2 microduplication (0.16%, 1/625), Smith-Magenis syndrome microdeletion (0.16%, 1/625), and Miller-Dieker syndrome microdeletion (0.16%, 1/625). Thus, the BoBs™ assay is a reliable and rapid test for detecting common aneuploidies and microdeletions for prenatal diagnosis, and could be used instead of karyotyping for detection of common aneuploidies as well as to provide additional information regarding microdeletions.

Abstract
Epidemiological studies have evaluated the association between maternal methylenetetrahydrofolate reductase (MTHFR) C677T, A1298C and methionine synthase reductase (MTRR) A66G polymorphisms and risk of neural tube defects (NTDs) in offspring. However, the results from the published studies on the association between these three polymorphisms and NTD risk are conflicting. To derive a clearer picture of association between these three maternal polymorphisms and risk of NTD, we performed meta-analysis. A comprehensive search was conducted to identify all case-control studies of maternal MTHFR and MTRR polymorphisms and NTD risk. We used odds ratios (ORs) with 95% confidence intervals (CIs) to assess the strength of the association. Overall, we found that maternal MTHFR C677T polymorphism (OR(TvsC) =1.20; 95% CI = 1.13-1.28) and MTRR A66G polymorphism (OR(GvsA) = 1.21; 95% CI = 0.98-1.49) were risk factors for producing offspring with NTD but maternal MTHFR A1298C polymorphism (OR(CvsA) = 0.91; 95% CI = 0.78-1.07) was not associated with NTD risk. However, in stratified analysis by geographical regions, we found that the maternal C677T polymorphism was significantly associated with the risk of NTD in Asian (OR(TvsC) = 1.43; 95% CI: 1.05-1.94), European (OR(TvsC) = 1.13; 95% CI: 1.04-1.24) and American (OR(TvsC) = 1.26; 95% CI: 1.13-1.41) populations. In conclusion, present meta-analysis supports that the maternal MTHFR C677T and MTRR A66G are polymorphisms contributory to risk for NTD.
