NEXMIF mutations in intellectual disability and epilepsy: A report of 2 cases and literature review / 中南大学学报(医学版)

More than 100 genes located on the X chromosome have been found to be associated with X-linked intellectual disability (XLID) to date, and NEXMIF is a pathogenic gene for XLID. In addition to intellectual disability, patients with NEXMIF gene mutation can also have other neurological symptoms, such as epilepsy, abnormal behavior, and hypotonia, as well as abnormalities of other systems. Two children with intellectual disability and epilepsy caused by NEXMIF gene mutation were treated in the Department of Pediatrics, Xiangya Hospital, Central South University from March 8, 2017 to June 20, 2020. Patient 1, a 7 years and 8 months old girl, visited our department because of the delayed psychomotor development. Physical examination revealed strabismus (right eye), hyperactivity, and loss of concentration. Intelligence test showed a developmental quotient of 43.6. Electroencephalogram showed abnormal discharge, and cranial imaging appeared normal. Whole exome sequencing revealed a de novo heterozygous mutation, c.2189delC (p.S730Lfs*17) in the NEXMIF gene (NM_001008537). During the follow-up period, the patient developed epileptic seizures, mainly manifested as generalized and absent seizures. She took the medicine of levetiracetam and lamotrigine, and the seizures were under control. Patient 2, a 6-months old boy, visited our department due to developmental regression and seizures. He showed poor reactions to light and sound, and was not able to raise head without aid. Hypotonia was also noticed. The electroencephalogram showed intermittent hyperarrhythmia, and spasms were monitored. He was given topiramate and adrenocorticotrophic hormone (ACTH). Whole exome sequencing detected a de novo c.592C>T (Q198X) mutation in NEXMIF gene. During the follow-up period, the seizures were reduced with vigabatrin. He had no obvious progress in the psychomotor development, and presented strabismus. There were 91 cases reported abroad, 1 case reported in China, and 2 patients were included in this study. A total of 85 variants in NEXMIF gene were found, involving 83 variants reported in PubMed and HGMD, and the 2 new variants presented in our patients. The patients with variants in NEXMIF gene all had mild to severe intellectual disability. Behavioral abnormalities, epilepsy, hypotonia, and other neurological symptoms are frequently presented. The phenotype of male partially overlaps with that of female. Male patients often have more severe intellectual disability, impaired language, and autistic features, while female patients often have refractory epilepsy. Most of the variants reported so far were loss-of-function resulted in the reduced protein expression of NEXMIF. The degree of NEXMIF loss appears to correlate with the severity of the phenotype.

Objective:To investigate the mechanisms of microRNA (miR)-103a-3p/chitinase-3-like protein 1 (CHI3L1) in the proliferation and vascular mimicry of ovarian cancer cells and its effect on transforming growth factor-β (TGF-β) pathway.Methods:The relationship between the expression level of miR-103a-3p and the overall survival rate of ovarian cancer patients was analyzed by bioinformatics. The human ovarian adenocarcinoma SKOV3 cells were divided into 4 groups: control group, miR-103a-3p mimic group, miR-103a-3p mimic+ CHI3L1 group and CHI3L1 group. Quantitative polymerase chain reaction (qPCR) and Western blotting were used to detect the expression levels of miR-103a-3p, CHI3L1 mRNA and CHI3L1 protein respectively. The expression level of YKL-40 in cell culture fluid was detected by enzyme-linked immunosorbent assay. The cell viability, proliferation ability and angiogenesis ability of the 4 groups were detected by CCK-8 method, clone formation experiment and angiogenesis experiment. The dual luciferase report verified that miR-130a-3p targeted CHI3L1.Results:The overall survival rate of ovarian cancer patients with high expression of miR-103a-3p was higher than that of patients with low expression of miR-103a-3p ( χ2=6.187, P=0.048). The differences in miR-103a-3p and CHI3L1 mRNA levels among the control group, miR-103a-3p mimic group, miR-103a-3p mimic+ CHI3L1 group and CHI3L1 group were statistically significant ( F=198.254, P<0.001; F=60.214, P<0.001), miR-103a-3p mimic group and miR-103a-3p mimic+ CHI3L1 group had higher miR-103a-3p levels than the control group (all P<0.001), CHI3L1 group had higher CHI3L1 mRNA level than the control group ( P<0.001). The expression levels of CHI3L1 protein in the 4 groups were 2.25±0.23, 1.19±0.12, 2.29±0.28 and 4.31±0.37, and the difference was statistically significant ( F=18.675, P<0.001). The expression levels of YKL-40 in the cell culture fluids of the 4 groups were (1.84±0.20) ng/ml, (0.95±0.08) ng/ml, (2.64±0.25) ng/ml, (6.27±0.79) ng/ml, and the difference was statistically significant ( F=35.297, P<0.001). The YKL-40 level of the CHI3L1 group was significantly higher than that of the control group ( P<0.001), the miR-103a-3p mimic group was lower than the control group ( P<0.001), and the miR-103a-3p mimic+ CHI3L1 group was higher than the miR-103a-3p mimic group ( P<0.001). The cell viabilities of the 4 groups were 100%±2.54%, 76.23%±2.13%, 104.89%±3.56% and 137.42%±2.80%, and the difference was statistically significant ( F=23.584, P<0.001). The cell viability of the miR-103a-3p mimic group was significantly lower than that of the control group ( P<0.001), the CHI3L1 group was higher than the control group ( P<0.001), and the miR-103a-3p mimic+ CHI3L1 group was higher than the miR-103a-3p mimic group ( P<0.001). The number of clones formed in the 4 groups were 76.85±4.67, 21.56±2.85, 72.06±5.07 and 169.63±9.21, and the difference was statistically significant ( F=31.541, P<0.001). The proliferation capacity of the miR-103a-3p mimic group was significantly lower than that of the control group ( P<0.001), the CHI3L1 group was higher than the control group ( P<0.001), and the miR-103a-3p mimic+ CHI3L1 group was significantly higher than the miR-103a-3p mimic group ( P<0.001). The differences in the relative tube lengths and the tube bramches of the 4 groups were both statistically significant ( F=24.254, P<0.001; F=27.564, P<0.001). The differences in TGF-β and Smad levels of the 4 groups were both statistically significant ( F=30.254, P<0.001; F=34.187, P<0.001). The results of dual luciferase experiments showed that compared with the NC group, the luciferase activity in cells co-transfected of miR-103a-3p and CHI3L1-wt was significantly reduced. The difference of luciferase activity between the cells transfected with NC and co-transfected with miR-103a-3p and CHI3L1-mut was not significant. Conclusion:MiR-103a-3p can directly inhibit the expression of CHI3L1 and inhibit the proliferation and angiogenesis of ovarian cancer SKOV3 cells to inhibit ovarian lymphatic metastasis and distant metastasis, which may be related to the TGF-β pathway.

Clinical analysis of 71 cases of anti-N-methyl-D-aspartate receptor encephalitis in children / 中华儿科杂志

Objective@#To investigate the clinical features, treatment strategies and long term outcomes of children with anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis.@*Methods@#The data of clinical features, auxiliary examinations, treatments and prognosis in children with anti-NMDAR encephalitis in Xiangya Hospital of Central South University from March 2014 to October 2017 were collected and retrospectively analyzed. A total of 71 patients were enrolled, including 33 males and 38 females. The youngest age of onset was 4 months old, and the age of onset was (9±4) years. The first-line immunotherapy treatment for anti-NMDAR encephalitis was short course corticosteroid (high-dose impulse therapy and oral maintenance therapy for 1 month in acute period) and (or) immunoglobulin. The clinical evaluation was performed 2 weeks after first-line immunotherapy treatment. The second-line immunotherapy treatment, including rituximab and (or) cyclophosphamide, would be started if the symptoms did not improve significantly and the modified Rankin scale (mRS) score ≥3. All patients were followed up and evaluated for prognosis. T-test, Mann-Whitney U, Chi square test and Fisher′s exact probability method were used for comparison between good outcome group and poor outcome group, first-line immunotherapy group and first-line immunotherapy combined with second-line immunotherapy group.@*Results@#The more common clinical manifestations were psychiatric symptoms (n=61, 86%), dyskinesia (n=55, 77%) and convulsions (n=51, 72%). Two cases (3%) had tumors. Electroencephalogram (EEG), cerebro-spinal fluid (CSF) and brain magnetic resonance imaging (MRI) studies were abnormal in 83% (59/71), 39% (27/69) and 38% (27/71) patients, respectively. For the treatment regimens, all the 71 patients underwent first-line immunotherapy, resulting in improvement within 14 days in 40 cases (56%), and 1 case (1%) died. The rest 30 cases (42%) received second-line immunotherapy. The patients were followed up for 5.0-41.8 months, with a median of 19.3 months. At the last follow-up, 49 cases (69%) recovered completely, 15 cases (21%) had mild disability, 6 cases (8%) had severe disability, 1 case (1%) died and 3 cases (4%) had relapse. There were significant differences between the groups with good prognosis and poor prognosis on admission to pediatric intensive care unit (PICU) and consciousness disorder (10/64 vs. 5/7, 39/64 vs. 7/7, P=0.047, 0.004). There were significant differences between first-line immunotherapy group and the first-line combined second-line immunotherapy group on admission to PICU, consciousness disorder, sleep disorder and first mRS score (12% (5/41) vs. 33% (10/30), 44% (18/41) vs. 93% (28/30), 56% (23/41) vs. 90% (27/30), 3 (1-5) vs. 4 (3-5), respectively; χ2=4.645, 18.555, 9.560, Z=5.184, P=0.031, <0.01, 0.002, <0.01, respectively).@*Conclusions@#Anti-NMDAR encephalitis can occur in all ages of children. The most common clinical manifestations are psychotic symptoms, dyskinesia and convulsions. Paraneoplastic cases are less common in children. Immunotherapy is effective. The second-line immunotherapy should be given after the failure of first-line therapy (mRS score≥3).

This patient presented with fever,seizure and bulging fontanelle when he was 6-month-old.According to the investigations,white blood cell (WBC),erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) increased significantly,and Streptococcus Pneumonia grew in both blood and cerebrospinal fluid (CSF).He responded to standard antibiotic treatment poorly even it lasted long enough.At the same time,the inflammation seemed to be over-activated,the WBC level was still elevated,high fever continued.Thus they thought of primary immunodeficiency and sent blood sample for gene panel testing (Sanger sequencing) but got negative result.At last,they added steroid together with anti-tuberculosis drug therapy,his temperature as well as the intracranial pressure became better ever since.At the age of 1 year and 1 month,he got another Streptococcus Pneumonia meningitis,while he was still on anti-tuberculosis drug therapy and tapering off steroid.At this time,he presented with coarse hair,hypohidrosis and delayed eruption of teeth,which strongly indicated Anhidrotic Ectodermal Dysplasia with Immunodeficiency (EDA-ID).NEMO is the most common gene responsible for EDA-ID and locates on X chromosome.It has a pseudogene named IKBKGP which locates downstream of NEMO.IKBKGP and NEMO share 3-10 exons with the homology of 99.8％,which makes it difficult to find out most real mutations within NEMO with Sanger sequencing.Then they performed PCR with the primer starting upstream of the shared exons.Finally,they found out the pathogenic mutation [c.505G ＞ C(p.A169P)] of NEMO,which has been reported.This finding led us to make the right diagnosis as well as the proper treatment and the prognosis for this patient.

Clinical features and genetic analysis of intellectual disability in children with epilepsy of unknown causes / 中华实用儿科临床杂志

Objective To explore the clinical features,genetic causes and prognosis of intellectual disability with epilepsy(ID-E)in children.Methods The data of unknown causes of ID-E children(n=40)who were identified in Department of Pediatrics,Xiangya Hospital of Central South University from March 2015 to March 2016 were respectively analyzed,and follow-up studies were performed to investigate the epilepsy control and intellectual deve-lopment.Results Forty unexplained ID-E included 25(62.5％)male,and 34(85.0％)cases were severe intellectual disability patients.The onset age of epilepsy was 0.16 to 8.00 years old,median age was 1.5 years old.Twenty cases(50.0％)had slow electroencephalogram background,and 22 cases(55.0％)had focal spikes.Ten cases(25.0％)had abnormal cranial images,with brain dysplasia or atrophy.Follow-up lasted from 0.58 to 1.58 years,and 19 cases(47.5％)had seizure control.Twenty-five cases(62.5％)had used at least 2 anti-epilepsy drugs during follow-up,and 19 cases(47.5％)had drug refractory epilepsy.Improvement of mental or motor development in epilepsy controlled group and the uncontrolled group were 12 cases(63.2％)and 2 cases(9.5％).There were separately 8 cases(8/40 cases,20.0％)and 3 cases(3/16 cases,18.8％)diagnosed respectively by whole genome-wide analysis of copy number variants(CNVs)and gene-panel whose CNVs test findings were negative.Conclusions ID-E patients of unknown causes have the following clinical features:they were mostly found in male patients with severe intellectual disability,and drug refractory epilepsy patients have rather high percentage;well controlling of epilepsy is useful for improvement of mental and motor development.Genetic analysis is significant for control and prognosis of ID-E patients,and genome-wide CNVs have high positive rates which can be used as first-tier test to detect genetic etiology of ID-E of unknown cause.

The biological characteristics of holoclone from ovarian cancer cell SKOV3 and its ability to form vasculogenic mimicry / 肿瘤

Objective: To observe the biological characteristics of holoclone cells which were sperated by single cell clone from hunman epithelial ovarian cancer SKOV3 cells and its ability to from vasculogenic mimicry (VM): formation. Methods: SKOV3 cells were cultured and separated into three different single cell clones by limited dilution method. The tumor formation test by in nude mice in vivo and soft agar colony formation test were used to compare the biological characteristics of the three kinds of single cell clones. Three-dimensional cell culture model was established to observe the ability of VM formation in three separated cell clones. The expression levels of CD1 33, matrix metalloproteinases-2 (MMP-2): and MMP-9 in holoclone cells, meroclone cells, paraclone cells and parental cells were detected by Western blotting. Results: Single cell clones were cultured for 10-14 days, and the average proportions of the three cell clones were (17.4±0.8): % (holoclone), (30.1 ±0.4): % (meroclone), and (52.5±1.1): % (paraclone), respectively. After three different cell clones were subcutaneously inoculated in female nude mice, the rate of tumor formation of holoclone was 80%, but those of meroclone and paraclone were both 0. The average cell clone formation rates of three cell clones were (16.7 ± 3.8): %, (6.5±1.5): % and (1.2±0.7): %, respectively (P < 0.05). Under the condition of three-dimensional cell cultivation, holoclone cells could form VM, whereas meroclone and paraclone cells couldn't. The expression levels of CD133, MMP-2 and MMP-9 proteins in holoclone group were significantly higher than those of the maternal SKOV3 cells group, and also higher than those of the meroclone and paraclone groups (P < 0.05). Conclusion: Three kinds of single cell clones have heterogeneousness in morphology and biological characteristics, and holoclone cells have the characteristics of tumor stem-like cells, which can form VM. Holoclone may be a SKOV3 cell subset with the higher ability of recurrence.

A survey on the iodine nutrition status and thyroid function in rural population of Jilin province / 中华内分泌代谢杂志

One hundred children aged 8-10 years and 100 adults aged 18-45 from their families in three townships Baoshan,Mingcheng,and Yantongshan of Panshi city,Jilin province were selected in April 2009. In addition,50 pregnant or lactating women,and their 50 infants aged 0-2 years were selected.The median level of iodine in salt at household was 30.2 mg/kg and that of drinking water was 2.8 μg/L.The median levels of urine iodine in school age chidren ( 196.5 μg/L),during pregnancy( 198.5 μag/L),lactation( 224.9 μg/L),and in infants (209.0 μg/L) all were optimal according to World Health Organization criteria.Only the median urine iodine in adults ( 269.0 μg/L) was more than adequate.The prevalence of goiter evaluated by B-ultrasound was 1.8％ in 8-10year-old children.The incidences of various thyroid dysfunctions were low in these residents,such as subclinical hyperthyroidism ( 2.1％ ),subclinical hypothyroidism ( 1.5％ ),and hyperthyroidism ( 1.2％ ). Subclinical hypothyroidism occurred mostly in adults (2.7％),pregnant women ( 1.7％ ),and lactating women ( 1.8％ ) ; and subclinical hyperthyroidism occurred mostly in 8-10 years old school chidren (4.5％) and lactating women (3.6％).These results show that the current iodized salt content has no harmful effect on thyroid function of rural residents in Jilin province.
