ABSTRACT

OBJECTIVE@#To carry out genetic testing and prenatal diagnosis for a woman featuring moderate intellectual disability (ID).@*METHODS@#The patient had presented at the First Affiliated Hospital of Zhengzhou University on April 28, 2021. With informed consent, peripheral blood and amniotic fluid samples were collected for the extraction of genomic DNA. Pathogenic copy number variations (CNVs) were detected with CNV-seq, and single gene variants were detected by whole exome sequencing (WES) and Sanger sequencing. Candidate variant was verified by Sanger sequencing, and CNV-seq and multiplex ligation-dependent probe amplification (MLPA) were used to detect fetal CNVs.@*RESULTS@#The 23-year-old woman had moderate ID, sideway walking, and unstable holding. Ultrasonography at 18+3 weeks' gestation had revealed no fetal abnormality. No pathogenic CNV was detected in the woman by CNV-Seq, while WES revealed that she has harbored a heterozygous c.1675C>T (p.Arg559*) variant of the DLG4 gene, which was verified by Sanger sequencing. Based on guidelines from the American College of Medical Genetics and Genomics, the variant was predicted to be likely pathogenic (PVS1+PM2_supporting). Sanger sequencing has confirmed that the fetus has inherited this variant, and CNV-Seq also revealed that that fetus has harbored a 0.1 Mb heterozygous deletion at Xp21.1, which has encompassed the DMD gene, and the result was verified by MLPA.@*CONCLUSION@#The heterozygous c.1675C>T variant of the DLG4 gene probably underlay the mental retardation in this woman, and her fetus was found to harbor the same variant in addition with deletion of the DMD gene, which may predispose to ID type 62.

ABSTRACT

The emerging of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) caused COVID-19 pandemic. The first case of COVID-19 was reported at early December in 2019 in Wuhan City, China. To examine specific antibodies against SARS-CoV-2 in biological samples before December 2019 would give clues when the epidemic of SARS-CoV-2 might start to circulate in populations. We obtained all 88,517 plasmas from 76,844 blood donors in Wuhan between 1 September and 31 December 2019. We first evaluated the pan-immunoglobin (pan-Ig) against SARS-CoV-2 in 43,850 samples from 32,484 blood donors with suitable sample quality and enough volume. Two hundred and sixty-four samples from 213 donors were pan-Ig reactive, then further tested IgG and IgM, and validated by neutralizing antibodies against SARS-CoV-2. Two hundred and thirteen samples (from 175 donors) were only pan-Ig reactive, 8 (from 4 donors) were pan-Ig and IgG reactive, and 43 (from 34 donors) were pan-Ig and IgM reactive. Microneutralization assay showed all negative results. In addition, 213 screened reactive donors were analyzed and did not show obviously temporal or regional tendency, but the distribution of age showed a difference compared with all tested donors. Then we reviewed SARS-CoV-2 antibody results from these donors who donated several times from September 2019 to June 2020, partly tested in a previous published study, no one was found a significant increase in S/CO of antibodies against SARS-CoV-2. Our findings showed no SARS-CoV-2-specific antibodies existing among blood donors in Wuhan, China before 2020, indicating no evidence of transmission of COVID-19 before December 2019 in Wuhan, China.

ABSTRACT

OBJECTIVE@#To assess the value of re-sampling for patients who had failed non-invasive prenatal testing (NIPT) due to low cell-free fetal DNA (cffDNA) fraction.@*METHODS@#Clinical data of 20 387 patients undergoing NIPT test was reviewed. The patients were re-sampled when initial blood test did not yield a result due to cffDNA fraction. The results were analyzed, and the outcome of pregnancy was followed up.@*RESULTS@#Among all samples, 17 (0.08%) had failed to yield a result due to low cffDNA fraction, all of which accepted re-sampling. A result was attained in 16 cases, with a success rate of 94.12%. Only one sample had failed the re-test.@*CONCLUSION@#For patients who had failed the initial NIPT due to low cffDNA fraction, re-sampling should be considered with gestational week and ultrasound results taken into consideration.

ABSTRACT

OBJECTIVE@#To carry out genetic testing and prenatal diagnosis for 29 Chinese pedigrees affected with tuberous sclerosis complex (TSC) and assess efficacy of combined next generation sequencing (NGS) and multiple ligation-dependent probe amplification (MLPA) for the diagnosis.@*METHODS@#NGS and MLPA were used in conjunct to detect variants of TSC1 and TSC2 genes among the probands of the pedigrees. Paternity test was carried out to exclude maternal DNA contamination. Prenatal diagnosis was provided to 14 couples based on the discoveries in the probands.@*RESULTS@#Twenty-seven variants were identified in the TSC1 and TSC2 genes among the 29 pedigrees, which yielded a detection rate of 93.1%. Respectively, 5 (18.5%) and 22 (81.5%) variants were identified in the TSC1 and TSC2 genes. Twelve variants were unreported previously. Prenatal diagnosis showed that five fetuses were affected with TSC, whilst the remaining nine were unaffected.@*CONCLUSION@#Above finding has expanded the spectrum of TSC1 and TSC2 gene variants. Combined NGS and MLPA has enabled diagnosis of TSC with efficiency and accuracy.

ABSTRACT

OBJECTIVE@#To assess the value of non-invasive prenatal testing based on cfDNA barcode-enabled single-molecule test (cfBEST) for the prenatal diagnosis of oculocutaneous albinism type I in a family.@*METHODS@#Prenatal genetic diagnosis was carried out by using the cfBEST-based method as well as invasive prenatal diagnosis through amniocentesis. The outcome of the pregnancy was followed up.@*RESULTS@#Non-invasive prenatal testing based on cfBEST showed a fetal DNA concentration of 6.6%, with the proportion of c.929_930insC (p.Arg311Lysfs*7) and c.1037-7T>A mutations being 45.7% and 0%, respectively. The posterior frequency of the negative results was 1, suggesting that the fetus carried neither of the two mutations. The result was consistent with that of invasive prenatal diagnosis, and the follow-up found that the fetus was normal.@*CONCLUSION@#Non-invasive prenatal testing based on cfBEST can be used to detect maternal and fetal genotypes in maternal cell-free DNA, which is clinically feasible.

ABSTRACT

Objective@#As cancer stem cells (CSCs) are considered as the origin of tumor development, recurrence, and drug resistance, we aimed to explore the mechanism related to modulating stemness in CSCs, thus facilitating to search for new therapeutic strategy for ovarian cancer. @*Methods@#In this study, ovarian cancer stem cells (OCSCs) induced from cell line 3AO and A2780 were enriched in serum-free medium (SFM). The effect of SURF4 on CSC-like properties was evaluated by sphere-forming assays, re-differentiation assays, quantitative real-time polymerase chain reaction, flow cytometry, Western blotting, cell viability assays and in vivo xenograft experiments. The downstream molecule participating in SURF4 maintaining stemness was screened by RNA-sequencing and identified by the experiments of gene function. @*Results@#SURF4 was upregulated expressed in OCSCs. Knockdown of SURF4 reduced the expression of the related stem markers (SOX2 and c-MYC), inhibited self-renewal ability, and improved the sensitivity to chemotherapeutic drugs (paclitaxel and cisplatin) in OCSCs.SURF4 knockdown also inhibited tumorigenesis in nonobese diabetic/severe combined immunodeficiency mice. BIRC3 expression was controlled by SURF4, and BIRC3 showed the similar effect as SURF4 did, and BIRC3 overexpression partially recovered stem-like properties abolished by SURF4 knockdown. @*Conclusion@#Our findings suggest that SURF4 possesses the ability to maintain stemness of OCSCs via BIRC3, and may serve as a potential target in stem cell-targeted therapy for ovarian cancer.

ABSTRACT

OBJECTIVE@#To determine the spectrum of pathological genetic variants among 405 Chinese pedigrees affected with oculocutaneous albinism (OCA).@*METHODS@#A total of 405 OCA patients were collected. High-throughput sequencing (The panel included TYR, OCA2, TYRP1 and SLC45A2 genes), Sanger sequencing and multiplex ligation-dependent probe amplification (MLPA) were used to analyze the genetic variants and patterns of each subtype.@*RESULTS@#The overall detection rate of genetic variants was 79.9% (647/810), and the variants included missense variants (57.3%, 371/647), frameshift variants (22.9%, 148/647), nonsense variants (13.9%, 90/647), splicing variants (5.6%, 36/647), and microdeletions (0.3%, 2/647). Thirty-six novel variants were detected. Of the 405 patients, 306 have carried 2 variant alleles (75.6%, 306/405), 35 carried 1 variant alleles (8.6%, 35/405), while no variant was detected in 64 patients. Among the 306 genetically diagnosed OCA patients, OCA1 was the most common form (74.5%, 228/306), compared with OCA2 (15.0%, 46/306), OCA3 (0.7%, 2/306) and OCA4 (9.8%, 30/306), respectively. One patient was found to harbor homozygous c.1262-4_c.1262-3insTAGA variant of the TYRP1 gene. Another patient was found to carry compound heterozygous variants of c.1214C>A (p.T405N) and c.1338delinsCG(p.V447Gfs*19) of the TYRP1 gene.@*CONCLUSION@#High-throughput sequencing in combination with Sanger sequencing and MLPA can effectively detect genetic variants associated with OCA. Above finding has expanded variant spectrum of OCA, which can facilitate genetic and prenatal diagnosis of this disease in China.

ABSTRACT

We report a case of non-invasive prenatal diagnosis of fetal ectodermal dysplasia caused by EDA gene mutations. The pregnant woman underwent prenatal diagnosis at 11 gestational weeks because of a childbearing history of ectodermal dysplasia. Cell-free DNA barcode-enabled single-molecule test (cfBEST) was used to detect the ectodermal dysplasia gene mutation, and chorionic villus sampling was also performed. The cfBEST results showed that the genotype of maternal EDA gene c.340C> T(p.Gln114*) was heterozygous, while the genotype of fetal EDA was normal wild-type (C/C), which were consistent with the results of villus sampling, suggesting that cfBEST can be used for non-invasive prenatal diagnosis of ectodermal dysplasia caused by EDA gene mutation.

ABSTRACT

Objective@#To evaluate the application value and significance of low-depth whole-genome sequencing for copy number variations (CNV-Seq) in the genetic diagnosis and prenatal diagnosis of X-linked ichthyosis (XLI) due to STS gene deletion.@*Methods@#Clinical data were collected from 3 616 subjects who received CNV-Seq, and single-gene test results were collected from 7 patients or pedigrees with ichthyosis in The First Affiliated Hospital of Zhengzhou University in 2018. The 3 616 samples included 2 891 prenatal samples from pregnant women (most were amniotic fluid samples, some fetal villus samples, very few umbilical blood samples) and 725 peripheral blood samples from other subjects. Genomic DNA was extracted from amniocytes or peripheral blood, and then subjected to CNV-Seq. Quantitative PCR (qPCR) and single nucleotide polymorphism (SNP) -comparative genomic hybridization (CGH) array were performed to verify the detected CNVs. Pathogenicity of the CNVs was analyzed according to the database of genomic variants (DGV) , database of genomic variation and phenotype in humans using ensembl resources (DECIPHER) , clinical genome resource (ClinGen) and online Mendelian inheritance in man (OMIM) .@*Results@#Of the 3 616 subjects receiving CNV-Seq, Xp22.31 deletion was identified in prenatal samples from 6 pregnant women, including 5 male and 1 female fetuses. The deleted fragment of Xp22.31 covered the XLI region containing the major gene STS. The parental CNV-Seq showed that the Xp22.31 deletion was spontaneous mutation in 2 of the 6 fetuses, and inherited from the parents in the other 4 fetuses. qPCR confirmed that the female fetus was a carrier of a complete heterozygous deletion of the STS gene, and there was a complete deletion of the STS gene in the other 5 male fetuses. SNP-CGH array also confirmed that the female fetus was heterozygous Xp22.31 deletion carrier, which was consistent with the CNV-Seq results. Ichthyosis gene panel sequencing in the 7 patients with ichthyosis showed 1 with harlequin ichthyosis, 2 with ichthyosis vulgaris, 3 with XLI, and no causative mutation in 1. CNV-Seq confirmed that Xp22.31 deletion existed in the above 2 patients with XLI due to STS gene deletion. Moreover, Xp22.31 duplication was found in 16 out of 3 616 subjects receiving CNV-Seq, but they were all individuals or fetuses with normal phenotype.@*Conclusions@#CNV-Seq is a stable and reliable method for screening whole-genome CNVs, and can be applied to genetic diagnosis and prenatal diagnosis of XLI due to STS gene deletion. The deletion of Xp22.31 fragment containing the STS gene can cause XLI, and the duplication of the same region is highly likely to be the polymorphic variation.

ABSTRACT

Objective To evaluate the adjunct role of nerve stimulator in ultrasound- guided axillary bra-chial plexus block. Methods 50 patients undergoing lower elbow surgery in our hospital were selected from Sep-tember 2016 to November 2017. They were randomly divided into two groups with 25 cases each,which are guid-ance of ultrasound combined with nerve stimulator group(group US)and ultrasound alone group(group U). 32 mL of 0.4% ropivocaine were administered in both groups. The onset time and duration of sensory blockade in mus-culocutaneous,radial,median and ulnar nerve were recorded. The extent of sensory block of each in nervated re-gion and the anesthetic effect of surgical field(rated as excellent,good and failure)were both assessed. The anes-thetic complications were also observed and recorded. Results There were no significant differences in the onset time and duration of sensory blockade in both groups(P > 0.05). The anesthetic effects of surgical field were 92%in group US and 84% in group U(P > 0.05). No major anesthetic complications occurred in two groups. Conclu-sion Ideal anesthetic effects are achieved in both groups,and the successful rate of anesthesia in group US is not significantly increased. The role of nerve stimulator as an adjunct to ultrasound - guided axillary brachial plexus block may be very limited.
