Dispite the lack the direct proof from the lost fetuses, the variants of ALPL and CDKN1C genes can explain the recurrence of fetal malformations for both couples.

To explore the genetic basis of a Chinese pedigree affected with progressive non-syndromic sensorineural hearing loss.

High-throughput DNA sequencing was carried out to analyze 415 genes associated with hereditary deafness in the proband. Sanger sequencing was carried out to verify the suspected variants among her family members.

The proband was found to carry a heterozygous c.842T>A (p.Ile281Asn) variant of the POU4F3 gene. The same variant was found among all other patients from the pedigree including the proband's mother, brother, aunt and maternal grandfather, but not among those with normal hearing. Based on the standards and guidelines of the American College of Medical Genetics and Genomics and the Association for Molecular Pathology, the c.842T>A(p.Ile281Asn) variant of the POU4F3 gene was predicted as likely pathogenic (PM2+PM5+PP1+PP3+PP4).

A Chinese pedigree affected by a rare type autosomal dominant deafness-15 (DFNA15) due to a novel c.842T>A (p.Ile281Asn) variant of the POU4F3 gene was identified. The result has facilitated genetic counseling and risk assessment for the pedigree.

A (p.Ile281Asn) variant of the POU4F3 gene was identified. The result has facilitated genetic counseling and risk assessment for the pedigree.

To explore the genetic basis of four children with congenital hyperinsulinemia (CHI).

The four children were subjected to high-throughput whole exome sequencing (WES). Candidate variants were validated by Sanger sequencing.

WES analysis has identified 4 variants in the ABCC8 gene and 1 variant in GLUD1, including a ABCC8 c.382G>A variant in case 1, compound heterozygous c.698T>C and c.4213G>A variants of the ABCC8 gene concomitant with a de novo 14.9 Mb microduplication of chromosome 15 in case 2, and ABCC8 c.331G>A variant in case 3, and de novo c.955T>C variant of the GLUD1 gene in case 4. Of these, c.698T>C of the ABCC8 gene and c.955T>C of the GLUD1 gene were unreported previously. Based on the American College of Medical Genetics and Genomics guidelines, the c.382G>A(p.Glu128Lys), c.698T>C(p.Met233Thr) and c.4213G>A(p.Asp1405Asn) variants of ABCC8 gene and c.955T>C(p.Tyr319His) variant of GLUD1 gene were predicted to be likely pathogenic(PM1+PM2+PP3+PP4, PM1+PM2+PM5+PP3+PP4, PM1+PM2+PP3+PP4 and PS1+PM1+PM2+PP3), and the c.331G>A (p.Gly111Arg) variant of ABCC8 gene was predicted to be uncertain significance(PM1+PM2+PP4).

The variants of the ABCC8 and GLUD1 genes probably underlay the pathogenesis of CHI in the four patients. Above results have facilitated clinical diagnosis and genetic counseling for the affected families.

To explore the genetic bases of 3 patients with periventricular nodular heterotopia and epileptic seizure.

The clinical data of three patients presenting with periventricular nodular ectopic with epileptic seizure were analyzed. Whole exome sequencing (WES) was performed on the patients, and Sanger sequencing was used to validate the suspected variants.

In three female patients, head MRI showed nodular gray matter ectopic in the bilateral ventricle. WES identified the heterozygous c.2720del T(p.Leu907Argfs*39) variant of FLNA gene in case 1 and her mother (case 2), and heterozygous c.1387_1390del GTGC(p.Val463Profs*34) of FLNA gene in case 3. According to the American College of Medical Genetics and Genomics standards and guidelines, the c.2720delT(p.Leu907Argfs*39) and c.1387_1390del GTGC (p.Val463Profs*34) variants of FLNA gene were predicted to be pathogenic (PVS1+PM2+PP1) and likely pathogenic(PVS1+PM2), respectively.

The c.2720delT(p.Leu907Argfs*39) and c.1387_1390del GTGC(p.Val463Profs*34) variants of FLNA gene may be the genetic cause of the three patients.

To analyze the pathogenic variants of the KIF1A gene and its corresponding protein structure in an autism spectrum disorder (ASD) family trio carrying harmful missense variants in the KIF1A gene.

The peripheral blood DNA of the patient and his parents was extracted and sequenced using whole exome sequencing (WES) technology and verified by Sanger sequencing. Bioinformatics software SIFT, PolyPhen-2, Mutation Taster, and CADD software were used to analyze the harmfulness and conservation of variants. The Human Brain Transcriptome (HBT) database was used to analyze the expression of the KIF1A gene in the brain. PredictProtein and SWISS-MODEL were further used to predict the secondary structure and tertiary structure of KIF1A wild-type protein and variant protein. PyMOL V2.4 was utilized to investigate the change of hydrogen bond connection after protein variant.

The WES sequencing revealed a missense variant c.664A>C (p.Asn222His) in the child's KIF1A gene, and this variant was a de novo variant. The harmfulness prediction results suggest that this variant is harmful. By analyzing expression level of KIF1A gene in the brain. It is found that KIF1A gene widely expressed in various brain regions during embryonic development. By analyzing the variant protein structure, the missense variant of KIF1A will cause many changes in the secondary structure of protein, such as alpha-helix, beta-strand, and protein binding domain. The connection of hydrogen bond and spatial structure will also change, thereby changing the original biological function.

The KIF1A gene may be a risk gene for ASD.

The KIF1A gene may be a risk gene for ASD.Genomic disorders caused by pathogenic copy number variation (pCNV) have proven to underlie a significant proportion of birth defects. With technological advance, improvement of bioinformatics analysis procedure, and accumulation of clinical data, non-invasive prenatal screening of pCNV (NIPS-pCNV) by high-throughput sequencing of maternal plasma cell-free DNA has been put to use in clinical settings. Specialized standards for clinical application of NIPS-pCNV are required. Based on the discussion, 10 pCNV-associated diseases with well-defined conditions and 5 common chromosomal aneuploidy syndromes are recommended as the target of screening in this consensus. Meanwhile, a standardized procedure for NIPS-pCNV is also provided, which may facilitate propagation of this technique in clinical settings.

Renal mesenchymal tumors are described as neoplasms with vascular, fibrous and adipose tissues. The renal lipoma is extremely rare renal mesenchymal tumor, typically originating from renal capsule and it is usually presented as well circumscribed homogenous fat containing mass. Angiomyolipoma (AML) is the most common benign mesenchymal renal tumor which is composed mature epithelioid cell. The renal AML usually presented as exophytic, non-infiltrative and fat contain tumor. The well differentiated renal retroperitoneal liposarcoma and lipoma seems to misdiagnosed by exophytic renal angiomyolipoma but the renal AML usually arise from renal parenchyma with characteristic images.

A 37-year-old woman came to our clinic with rapid growth renal mass and pain. The spiral abdominopelvic computed tomography scan (CT-scan) showed well circumscribed hypoheterodense fat containing mass near to middle pole of right kidney with minimal fat stranding without neovascularity and cortical defect. The Patient underwent off d to pre-operative diagnosis.

Fibromodulin (FMOD) is a secretory protein which is considered a major component of extracellular matrix. Its dysregulation in different types of cancer implies it as a promising target for cancer therapy. Within the scope of its rather wide expression in different tumors, we studied expression of FMOD and effect of anti-FMOD antibody in bladder cancer cells in order to identify new target for diagnostic and therapeutic interventions. We report here for the first time the expression of FMOD in bladder cancer cell lines in comparison to the normal cell line and tissues.

A peptide-based produced anti-FMOD murine monoclonal antibody (mAb) (clone 2C2-A1) was applied for evaluation of FMOD expression in bladder cancer and normal tissues by immunohistochemistry (IHC) staining. Furthermore, the expression of FMOD was examined in human bladder cell lines, 5637 and EJ138, as well as a non-cancerous human cell line, human fetal foreskin fibroblast (HFFF), by immunocytochemistry (ICC) and flow cytometry. The apoptosof FMOD in bladder cancer. This significant surface expression of FMOD in bladder cancer with no expression in normal bladder tissues and the capacity of inducing apoptosis through directed targeting of FMOD with specific monoclonal antibody might candidates FMOD as a diagnostic marker as well as a potential immunotargeting with monoclonal antibody.Materials and Methods The expression of NPM1 was analyzed by PCR and Western blot. NPM1 silencing bladder cancer cells (T24/DDP Lv-NPM1, PUMC-91/DDP Lv-NPM1) and overexpressing bladder cancer cells (T24/DDP Lv5-NPM1, PUMC-91/DDP Lv5-NPM1) were established by lentivirus and limited dilution method. KU-55933 concentration The efficiency of gene interference was detected by fluorescence microscopy and Western blot. The migration ability and invasion ability of tumor in vitro were analyzed by wound healing assay and transwell cell invasion test, and the tumorigenic ability in vivo was judged by nude mouse tumorigenicity assay. Results Compared with the corresponding negative control group, both NPM1 silencing cell lines T24/DDP Lv-NPM1 and PUMC-91/DDP Lv-NPM1 showed strong migration ability and high invasive ability. At the same time, there was no significant difference in migration ability and the invasive cells proportion between NPM1 overexpressing cell line and related negative control group. NPM1 silencing bladder cancer cells had obvious tumorigenicity in vivo.
