RESUMEN
OBJECTIVE@#To analyze the clinical phenotype and genetic variant in a child with Raynaud-Claes syndrome (RCS).@*METHODS@#A child who was diagnosed with RCS at the Children's Hospital Affiliated to Zhengzhou University for delayed language and motor development in August 2022 was selected as the study subject. Clinical data of the child were collected, and potential genetic variant was detected by next-generation sequencing and Sanger sequencing. The pathogenicity of the candidate variant was analyzed.@*RESULTS@#The child, a 4-year-and-4-month-old male, has manifested global developmental delay, speech disorders, special facial features and behavioral abnormalities. Genetic testing revealed that he has harbored a hemizygous c.1174C>T (p.Gln392Ter) variant of the CLCN4 gene, which was not detected in either of his parents. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the variant was rated as pathogenic (PVS1+PS2+PM2_Supporting).@*CONCLUSION@#The c.1174C>T (p.Gln392Ter) variant of the CLCN4 gene probably underlay the PCS in this child. Above finding has expanded the mutational spectrum of the CLCN4 gene and enabled genetic counseling and prenatal diagnosis for his family.

The clinical phenotypes and genotypes of a child with autism spectrum disorder (ASD) concomitant with MYT1L gene mutation were analyzed retrospectively, who was admitted to the Department of Rehabilitation Medicine of Henan Children′s Hospital in April 2019.Whole genome sequencing and copy number variations detection were performed on the child and relevant articles about MYT1L mutation were subjected to a literature review.It was found that this child had a missense mutation of MYT1L gene (c.2186T>G, p.Met729Arg) in 15 exon and was in a state of chimera, with about 10% of the mutation rate.This mutation was not identified in the parents and brother of this patient.A total of 18 reports of MYT1L-related genetic abnormalities were retrieved, including 53 patients in total (including this case), including 22 patients with point mutations and 30 patients containing MYT1L gene region with 2p25.3 chromosomal microdeletions.The incidence of autism was 45.0% (18/40 cases), that of overweight/obesity was 70.2% (33/47 cases) and that of dysnoesia/hypoevolutism was 96.2%(51/53 cases). However, chimeras had relatively mild symptoms.It indicates that the mutation of MYT1L is an important risk factor of ASD, but chimeras have mild symptoms.The children with ASD who are obese or overweight should be alerted to the possible presence of MYT1L mutation, and genetic testing can be performed to confirm the diagnosis and the possibility of chimerism.The spectrum of genetic mutations in ASD was expanded in this study.

Ovarian cancer is one of the most common gynecological malignancies leading to female deaths, and its early diagnosis and prevention are very complicated. Therefore, biomarkers for this disease prediction and prognosis are urgently needed for early diagnosis and individualized treatment. miRNAs are short-chain, highly conserved non-coding RNA molecules that mainly degrade or inhibit target genes at the post-transcriptional level to regulate cell growth, proliferation, differentiation, metabolism, and apoptosis. Existing studies have confirmed that miRNAs can be used as potential biomarkers for clinical diagnosis and treatment of cancer. Moreover, tumor-related miRNAs play an important role in the occurrence, invasion and metastasis of ovarian cancer by regulating the expression of multiple oncogenes and tumor suppressor genes. In this paper, the roles of miRNAs as biomarkers for early prevention or detection of ovarian cancer, prognostic diagnosis and treatment targets were reviewed, and the future clinical application of miRNA in patients with ovarian cancer was proposed.
RESUMEN
OBJECTIVE: To analyze the clinical and molecular genetic characteristics of 2 cases of fructose-1,6-bisphosphatase deficiency in the same family to provide evidence for the precise treatment,genetic counseling and prenatal diagnosis.METHODS: Clinical data were collected from 2 patients with hypoglycemia encephalopathy,and molecular genetic analysis was performed using targeted capture next-generation sequencing. RESULTS: The 2 patients were siblings,the male proband was 7 years old,mainly manifested with convulsions after hunger or ingestion of a large amount of fructose,accompanied by ketoacidosis;clinical diagnosis was hypoglycemia encephalopathy,and fructose metabolism abnormalities was suspected. The younger brother was 4 years old,mainly showing hunger and sweating in the morning,stomach ache after eating fruit,and convulsion episode once after hunger. Next-generation sequencing results showed that the siblings had c.333+1_2 delinsTC and c.490 G>A compound heterozygous mutations in the FBP1 gene,and their parents were carriers with normal phenotype.The c.333+1_2 delins TCis a novel mutation,c.490 G>A is a reported pathogenic mutation,and the two patients were diagnosed with fructose-1,6-bisphosphatase deficiency genetically. CONCLUSION: For children with unexplained hypoglycemia,convulsions and metabolic acidosis,the fructose-1,6-bisphosphatase deficiency should be considered. Early genetic analysis is helpful to clarify the cause,make precise treatment and improve prognosis.

BACKGROUND: The poor retention and survival of donor cells implanted into the myocardium limit the efficacy of cell therapy for myocardial infarction. Embedding cells in natural or synthetic biomaterials is a strategy to address this issue. OBJECTIVE: To explore the effects of bone marrow mesenchymal stem cells (BMSCs) encapsulated in hyaluronic acid (HA) hydrogel on cardiac function after myocardial infarction. METHODS:BMSCs from male Sprague-Dawley rats were isolated and cultured,and then HA-encapsulated BMSCs were cultured in vitro in the three-dimensional manner. A model of myocardial infarction was made by cutting the anterior descending artery of female Sprague-Dawley rats. After 1 week, the model rats were screened by ultrasonic testing and then eligible ones were randomly divided into four groups: PBS group (n=8), HA group (n=8), BMSCs group (n=29), and HA-encapsulated BMSCs group (n=29). At 1 week after modeling, the model rats underwent the secondary thoracotomy and the implants were injected into the marginal zone and infarcted region in corresponding groups. The survival rate and apoptosis of implanted cells were examined at post-injection day 1, week 1 and week 2 by RT-PCR and TUNEL respectively. At post-injection week 4, changes of cardiac microstructure and function were evaluated by histological examination and echocardiography. RESULTS AND CONCLUSION: Compared with the BMSCs group, HA hydrogel significantly enhanced the survival rate and reduced the apoptotic rate of BMSCs at post-injection day 1 and week 2 (both P < 0.05). At post-injection week 4, the HA+BMSCs combined treatment yielded the best recovery of cardiac function (P < 0.05). To conclude, HA hydrogel can act as a vehicle for BMSCs delivery and improve the beneficial effects of implanted BMSCs in early myocardial repair(within 2 weeks after infarction)via enhancing cell retention and survival.
