Pregnancy-related diseases including preeclampsia, gestational diabetes mellitus, preeclampsia, macrosomia and fetal growth restriction can seriously affect maternal health and pregnancy outcome. Early prediction and timely intervention are important means to reduce the risk. Fetal cfDNA and prediction of pregnancy-related diseases have become a hot topicfor current research. This paper reviews the latest progress made in the field.Perlman syndrome is a rare autosomal recessive congenital overgrowth syndrome caused by pathogenic variants of the DIS3L2 gene at 2q37 region. Clinically this syndrome is characterized by polyhydramnios, macrosomia, distinctive facial appearance, and renal dysplasia. Prognosis of the disease is poor, and survivors usually have mental delay and a high risk of developing Wilms tumor. At present, the pathogenesis of this disease is still poorly understood. This article intends to provide a review for this disease.
To explore the influence of long non-coding (lnc) RNA Gm15645 on the podocyte injury in mice with diabetic nephropathy.

Male db/db mice (with Type 2 diabetes) with a genetic background of C57BLKs/J and db/m mice (healthy) born in littermates were randomly divided into three groups. db/db group was injected with lncRNAGm15645 shRNA lentivirus with a podocyte-specific marker NPHS2; db/db blank group was injected with saline, and db/db control group was injected withnon-sense lentivirus. The results of PAS staining, pathological changes of renal tissue, relative expression of GSK-3beta, and podocin expression were compared.

lncRNAGm15 645 was overexpressed and podocin was down-regulated in the lentivirus overexpressed group. Mesangial cell proliferation, mesangial matrix hyperplasia, thickened basement membrane, widely fused foot process, and podocyte injury were observed by PAS staining. The expression of Gm15645 in the db/db group was significantly lower than that of the db/db blank group and db/db control group (P< 0.05), while the expression of podocin was higher (P< 0.05). Gm15645 was co-stained with podocin in renal tissue, and the target gene was GSK-3beta.

lncRNAGm15645 may provide an early biomarker for the occurrence of podocyte injury in diabetic nephropathy. The mechanism may be related to the feedback regulation of GSK-3beta gene.

To investigate the clinical effect of expanded non-invasive prenatal testing (NIPT-plus) for serological screening of fetuses with high-risk for Down's syndrome.

To retrospectively study the screening results, prenatal diagnosis and pregnancy outcomes of 1561 midterm pregnant women underwent NIPT-plus in our center from September 2018 to December 2019 due to serological screening with high-risk for Down's syndrome(≥ 1/270).

45 pregnant women had a high-risk with a detection rate of 2.88% (45/1561) of 1561 pregnant women who performed NIPT-plus. 40 pregnant women underwent invasive prenatal diagnosis and 20 cases were confirmed with a positive predictive value of 50.0% (20/40). Statistical analysis showed that NIPT-plus has a high detection rate for trisomy 21, sex chromosomal aneuploidy, and MMS in the 0.1/90 group, but with a positive predictive value lower than the other two groups.

The detection rate and PPVs of NIPT-plus in different groups of Down's high-risk pregnant women was different. NIPT-plus can reduce the pressure of prenatal diagnosis and can be used as a screening method for Down's syndrome with high risk in pregnant women.

To study rare para-Bombay blood type Bm
and to investigate the molecular genetic basis of para-Bombay phenotype in a Chinese family.

ABO and H phenotype of the proband and her pedigree were determined with serological methods. The ABO genotype was analyzed by polymerase chain reaction-sequence specific primer(PCR-SSP). The full coding region of alpha-l,2 fucosyltransferase (FUT1) gene of the pedigree was analyzed by polymerase chain reaction and direct sequencing of the amplified fragments. The haplotype of the FUT1 gene were analyzed by cloning sequencing.

The rare para-Bombay blood type Bm
was identified in the proband, with ABO*B.01/ABO*O.01.01 genotype. Two variants of FUT1 gene, c.508dupT and c.787A>C, were found in the proband. The cloning sequencing revealed that the two variants were on different alleles, and the haplotype of FUT1 gene was h
/h
. Both of the two variants were predicted to cause inactivation of the enzyme, which is consistent with the result of serological techniques.

Two new alleles of FUT1 gene (h
and h
), which were associated with para-Bombay phenotype, were identified in the Chinese pedigree.

To analyze the correlation of methylation status of dachshund homolog 1 (DACH1) gene in tumor tissues with clinicopathological characteristics and prognosis of patients of esophageal cancer.

Tumor tissue, paracancerous tissue and normal esophageal mucosal specimens of 104 patients with esophageal cancer were collected. Methylation-specific PCR was used to determine the methylation status of the DACH1 gene. Univariate analysis and multivariate Logistic regression model were used to analyze the correlation between DACH1 methylation status and clinical pathological characteristics of the patients. Kaplan-Meier survival curve was used to analyze the relationship between DACH1 methylation status and prognostic survival of patients.

The methylation rate of the DACH1 gene in esophageal cancer tumor tissue was 30.77% (32/104), which was higher than those in adjacent tissues (1.92%) and normal esophageal mucosa (0%) (P< 0.05). The methylation status of the DACH1gene in tumor tissues of patients did not correlerentiation, TNM stage, and lymph node metastasis of patients are independent risk factors for the methylation status of the DACH1 gene. Patients with esophageal cancer but unmethylated DACH1 gene have a longer prognostic survival.
To apply combined non-invasive prenatal testing (NIPT), chromosomal karyotyping and chromosomal microarray for the screening and prenatal diagnosis of a fetus with supernumerary small marker chromosome (sSMC).

Standard NIFTY and full gene NIFTY kits were applied to detect free DNA (cfDNA) isolated from peripheral blood sample of a pregnancy woman. Amniocentesis was carried out for the woman for an abnormal NIPT result. G-banded karyotyping and single nucleotide polymorphism array (SNP array) were used to determine the karyotype and copy number variants in the fetus. The result was validated with a fluorescence in situ hybridization (FISH) assay.

Both the standard NIFTY and full gene NIFTY indicated abnormal dup(chr12707 334-33 308 759), for which the T score value of copy number anomaly in full gene NIFTY is 6.823, which is higher than the standard NIFTY's T-score value of 3.9535. The two NIFTY results were both above the normal threshold ± 3. Conventional G-banding analysis of amniocytes showed that the fetus has a karyotype of 47,XY,+mar. SNP-array delineated duplication of 12p (arr [hg19]12p13.33p11.1 (173 786_34 385 641)× 4, which was verified by FISH. Lirametostat cell line Based on the above results, the fetus was diagnosed as a novel case of Pallister-Killian syndrome.

To investigate the genetic etiology, clinical diagnosis and treatment of a child with pancytopenia, failure to thrive and pulmonary infection.

Peripheral blood samples of the child and her parents were collected. Genomic DNA was extracted. Genetic variants associated with hematological diseases were detected by high-throughput sequencing.

Three variants of TCN2 gene were found, one of which located in exon 5 upstream(c.581-8A>T), the parents has carried this variant; one in exon 6 (c.924_927del), the variant was originated from the mother; one in exon 7 (c.973C>T), the variant has ocurred de novo. The variants pathogenic analysis combined with clinical manifestation, pancytopenia, the increase in methylmalonic acid level and increased homocysteine, the child was diagnosed with transcobalaminIIdeficiency. The patient presented with respiratory infection, which was confirmed to be pneumocystosis by lung radioscopy and pathogenic high-throughput sequencing of broncho-alveolar lavage fluid. The patient presented with acute respiratory distress syndrome during the treatment with intramuscular injection of vitamin B
, and improved after anti-infection with compound sulfamethoxazole and symptomatic support treatment.

We reported a case of Chinese child with TCNII deficiency due to novel gene variant, and analyzed the pathogenicity of the three variants. The treatment of TCNII deficiency with cobalamin should be individualized.
