Exploring the effectiveness of endometrial receptivity array and immune profiling in patients with multiple implantation failure：A retrospective cohort study based on propensity score matching.

This study aimed to evaluate the effectiveness of the endometrial receptivity array (ERA), endometrial immune profiling, and a combination of both in improving the pregnancy outcomes for multiple implantation failure patients. According to patients' willingness, 1429 women who incurred at least two or more consecutive implantation failures in IVF/ICSI treatment opted for frozen embryo transfer and were divided into four groups: 'No test', 'Immune Profiling', 'ERA' and 'ERA+ Immune Profiling'. Women in three test groups underwent timed endometrial biopsy for ERA, immune profiling, a combination of both. We observed the overall incidence rates of the displaced window of implantation (WOI) and endometrial immune dysregulation were 75.14% and 79.29%, respectively. After 1:1 propensity score matching (PSM), our data revealed that the 'ERA' and 'ERA + Immune Profiling' groups demonstrated significantly higher rates of biochemical, clinical, ongoing pregnancy, and implantation compared to the 'No test' group (p < 0.01). The 'Immune Profiling' group showed a higher implantation rate compared to 'No test' group (p < 0.05). Furthermore, when comparing three test groups, the 'ERA + Immune Profiling' group exhibited notably higher rates of clinical and ongoing pregnancy compared to the 'Immune Profiling' group (p < 0.017). However, there was no association between endometrial immune profiling and ERA phases, and their results did not differ between embryo implantation and non-implantation in these patients. Our findings underline the increased implantation rates by use of ERA and endometrial immune profiling in patients with multiple implantation failure, either individually or corporately. Moreover, a combination of both could improve their pregnancy outcomes significantly.

Myelin Oligodendrocyte Glycoprotein Antibody-Associated Disease (MOGAD) Following Adenovirus Meningitis After First Delivery: Case Report and Literature Review.

Myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) is a group of central nervous system (CNS) demyelinating diseases caused by autoantibodies against myelin oligosaccharide protein (MOG), a myelin sheath component protein, and present with a variety of symptoms, including optic neuritis, myelitis, acute disseminated encephalomyelitis (ADEM), brainstem encephalitis, and corticobasal encephalitis. It is currently unknown at what point in life MOGAD can develop or how it can be triggered by autoimmune mechanisms. Here, we report a case of a mature woman who suffered from adenoviral meningitis one month after childbirth and developed MOGAD but was able to return to child rearing with high-dose methylprednisolone therapy. This case suggests that the risk of developing MOGAD early after childbirth may be increased. The case also suggested that adenoviral infection may be involved in the development of MOGAD.

Factors associated with enteral nutrition tolerance after trauma laparotomy of the small bowel and mesenteric injuries by blunt trauma.

BACKGROUND: In patients with blunt injury due to abdominal trauma, the common cause for laparotomy is damage to the small bowel and mesentery. Recently, postoperative early enteral nutrition (EEN) has been recommended for abdominal surgery. However, EEN in patients with blunt bowel and/or mesenteric injury (BBMI) has not been established. Therefore, this study aimed to identify the factors that affect early postoperative small bowel obstruction (EPSBO) and the date of tolerance to solid food and defecation (SF + D) after surgery in patients with BBMI. METHODS: We retrospectively reviewed patients who underwent laparotomy for BBMI at a single regional trauma center between January 2013 and July 2021. A total of 257 patients were included to analyze the factors associated with enteral nutrition tolerance in patients with EPSBO and the postoperative day of tolerance to SF + D. RESULTS: The incidence of EPSBO in patients with BBMI was affected by male sex, small bowel organ injury scale (OIS) score, mesentery OIS score, amount of crystalloid, blood transfusion, and postoperative drain removal date. The higher the mesentery OIS score, the higher was the EPSBO incidence, whereas the small bowel OIS did not increase the incidence of EPSBO. The amount of crystalloid infused within 24 h; the amount of packed red blood cells, fresh frozen plasma, and platelet concentrate transfused; the time of drain removal; Injury Severity Score; and extremity abbreviated injury scale (AIS) score were correlated with the day of tolerance to SF + D. Multivariate analysis between the EPSBO and non-EPSBO groups identified mesentery and small bowel OIS scores as the factors related to EPSBO. CONCLUSION: Mesenteric injury has a greater impact on EPSBO than small bowel injury. Further research is needed to determine whether the mesentery OIS score should be considered during EEN in patients with BBMI. The amount of crystalloid infused and transfused blood components within 24 h, time of drain removal, injury severity score, and extremity AIS score are related to the postoperative day on which patients can tolerate SF + D.

A robust and lightweight deep attention multiple instance learning algorithm for predicting genetic alterations.

Self-attention mechanism-based algorithms are attractive in digital pathology due to their interpretability, but suffer from computation complexity. This paper presents a novel, lightweight Attention-based Multiple Instance Mutation Learning (AMIML) model to allow small-scale attention operations for predicting gene mutations. Compared to the standard self-attention model, AMIML reduces the number of model parameters by approximately 70%. Using data for 24 clinically relevant genes from four cancer cohorts in TCGA studies (UCEC, BRCA, GBM, and KIRC), we compare AMIML with a standard self-attention model, five other deep learning models, and four traditional machine learning models. The results show that AMIML has excellent robustness and outperforms all the baseline algorithms in the vast majority of the tested genes. Conversely, the performance of the reference deep learning and machine learning models vary across different genes, and produce suboptimal prediction for certain genes. Furthermore, with the flexible and interpretable attention-based pooling mechanism, AMIML can further zero in and detect predictive image patches.

How a winding-down oil refinery park impacts air quality nearby?

It is always difficult to compare, let alone estimate, the difference of air pollutant concentrations before and after closure of a major source because the pollutants cannot be traced or predicted after entering the ambient. Indeed, we are not aware of any studies specifically related to the air pollutants impacted by a winding-down source. In this work, we applied nine years (2010-2018) online measurement of air pollutants (including PM10, PM2.5, NO2, SO2, O3 and VOCs) to investigate (i) the temporal behavior of air pollutants before and after closure of an oil refinery park by using pair-wise statistics and correlations between wind speed and direction, and (ii) the source impacts on O3 concentrations using PMF coupled with multiple linear regression (MLR) analysis (PMF-MLR). Example applications are presented at two monitoring sites (A and B) close to the Kaohsiung Oil Refinery (KOR), located in the southern industrial city of Taiwan. The results show that the KOR shutdown changed air pollutant concentrations to a certain extent in these study areas. We also conclude that, instead of using propylene-equivalent and ozone formation potential (OFP) concentrations, it is better to estimate the formation of O3 based on PMF-MLR analysis as developed in this study. The PMF analysis has identified various VOCs sources at both sites including solvent usage, petrochemical industrial sources, industrial emissions, vehicle-related sources, vegetation emissions and aged air-masses. Also, the MLR model shows that both the background sources and petrochemical industrial sources may significantly change O3 concentrations.

Concurrent Ovarian and Tubal Ectopic Pregnancy After IVF-ET: Case Report and Literature Review.

Ovarian pregnancy (OP) coupled with tubal ectopic pregnancy is rare. We present a case of coexistent ovarian and tubal ectopic pregnancies in the same adnexa resulting from in vitro fertilization and embryo transfer (IVF-ET) for tubal occlusion. The patient presented with mild vaginal bleeding without abdominal pain. OP was diagnosed via sonographic findings of an ectopic gestational sac (GS) and yolk sac that seemed to be inside her left ovary. Laparoscopic exploration confirmed this diagnosis, and ipsilateral tubal ectopic pregnancy was suspected during surgery. The patient underwent left salpingectomy and resection of the ovarian lesion. A subsequent histopathological examination verified the diagnosis of coexistent ovarian and tubal ectopic pregnancy. Though the mechanism underlying concurrent OP and tubal ectopic pregnancy is still unclear, clinicians should be cautious of potential combined ectopic pregnancy when dealing with patients who have received more than one embryo transfer.

Cushing's Syndrome Due to a Functional Thymic Neuroendocrine Tumor in Multiple Endocrine Neoplasia Type 1 Syndrome.

Multiple endocrine neoplasia type 1 (MEN 1) syndrome is characterized by endocrinopathies and could be associated with thymic neuroendocrine tumors (NET). On rare occasions, they can be functional adrenocorticotropic hormone-secreting thymic carcinoid leading to Cushing's syndrome. In this report, we describe a case of adrenocorticotropic hormone (ACTH)-dependent Cushing's syndrome due to a thymic NET associated with MEN type 1 syndrome. We highlight its aggressive clinical course, the premise for a high index of suspicion for an ectopic ACTH secretion, and the need for early surgical resection combined with medical therapy and alternative treatments.

Co-registration Analysis of Fluorodopa and Fluorodeoxyglucose Positron Emission Tomography for Differentiating Multiple System Atrophy Parkinsonism Type From Parkinson's Disease.

It is difficult to differentiate between Parkinson's disease and multiple system atrophy parkinsonian subtype (MSA-P) because of the overlap of their signs and symptoms. Enormous efforts have been made to develop positron emission tomography (PET) imaging to differentiate these diseases. This study aimed to investigate the co-registration analysis of 18F-fluorodopa and 18F-flurodeoxyglucose PET images to visualize the difference between Parkinson's disease and MSA-P. We enrolled 29 Parkinson's disease patients, 28 MSA-P patients, and 10 healthy controls, who underwent both 18F-fluorodopa and 18F-flurodeoxyglucose PET scans. Patients with Parkinson's disease and MSA-P exhibited reduced bilateral striatal 18F-fluorodopa uptake (p < 0.05, vs. healthy controls). Both regional specific uptake ratio analysis and statistical parametric mapping analysis of 18F-flurodeoxyglucose PET revealed hypometabolism in the bilateral putamen of MSA-P patients and hypermetabolism in the bilateral putamen of Parkinson's disease patients. There was a significant positive correlation between 18F-flurodeoxyglucose uptake and 18F-fluorodopa uptake in the contralateral posterior putamen of MSA-P patients (rs = 0.558, p = 0.002). Both 18F-flurodeoxyglucose and 18F-fluorodopa PET images showed that the striatum was rabbit-shaped in the healthy control group segmentation analysis. A defective rabbit-shaped striatum was observed in the 18F-fluorodopa PET image of patients with Parkinson's disease and MSA-P. In the segmentation analysis of 18F-flurodeoxyglucose PET image, an intact rabbit-shaped striatum was observed in Parkinson's disease patients, whereas a defective rabbit-shaped striatum was observed in MSA-P patients. These findings suggest that there were significant differences in the co-registration analysis of 18F-flurodeoxyglucose and 18F-fluorodopa PET images, which could be used in the individual analysis to differentiate Parkinson's disease from MSA-P.

[Comparison study on sensitivity of five ophthalmic antibiotics to common drug-resistant Staphylococci on ocular surface].

Objective: To investigate the in vitro antibacterial sensitivity of levofloxacin, tobramycin, cefazolin sodium, clindamycin and fusidic acid to 67 strains of Staphylococci in ocular surface infection. The purpose of this study is to provide reference for clinical selection of drugs. Methods: Experimental study. Sixth-seven strains of drug-resistant Staphylococci isolated from the Department of Microbiology, Henan Provincial Ophthalmic Hospital during January 2018 and May 2019 were collected. There were 67 strains of Staphylococci including 28 strains of drug-resistant Staphylococcus epidermidi, 17 strains of drug-resistant Staphylococcus aureus, 15 strains of drug-resistant Staphylococcus intermedius and a few other kinds of drug-resistant Staphylococci. The minimum inhibitory concentrations (minimum inhibitory concentration, MIC) of levofloxacin, tobramycin, cefazolin sodium, clindamycin and fusidic acid in 67 strains of drug-resistant Staphylococci were determined by microliquid-based method. The sensitivity was determined according to the American CLSI-M100 standard. The statistical analysis of the data was carried out by using two-dimensional test and Fisher accurate test. Results: Fourteen strains of fusidic acid were sensitive to 17 strains of MRS-Meca-resistant Staphylococcus epidermidis, the difference between fusidic and levofloxacin is statistically significant; 14 strains of cefazolin sodium and 11 strains of fusidic acid were sensitive to 14 strains of ß-Lac enzyme-producing Staphylococcus aureus, and there were significant differences between the two drugs and levofloxacin; 6 strains of cefazolin sodium and 5 strains of fusidic acid were sensitive to 10 strains of MRS-Meca-resistant Staphylococcus intermedius, as compared to levofloxacin, there were significant differences between cefazolin sodium and levofloxacin (P=0.011,0.033). Cefazolin sodium was sensitive to 5 strains of MRS-Meca-positive other drug-resistant Staphylococci, which was significantly different from levofloxacin (P=0.048); 54 and 48 strains of cefazolin sodium and fusidic acid were sensitive to 67 strains of drug-resistant Staphylococci, and the sensitive rates were 80.1% and 71.6%, respectively, which were significantly higher than those of levofloxacin, tobramycin and clindamycin. There were significant statistical differences between drug sensitivity (χ²=18.377,9.940；P=0.000,0.003). Conclusions: The sensitivity of cefazolin sodium and fusidic acid to 67 strains of drug-resistant Staphylococci is better than that of levofloxacin, tobramycin and clindamycin, these findings may provide guidance for the clinical treatment of drug-resistant Staphylococci in ocular infection.

Clinical study on ixazomib in the treatment of multiple myeloma. / ä¼Šæ²™ä½ç±³æ²»ç–—å¤šå‘æ€§éª¨é«“ç˜¤çš„ä¸´åºŠç ”ç©¶.

OBJECTIVES: To evaluate the efficacy and safety of ixazomib in the treatment of multiple myeloma. METHODS: A total of 43 patients with multiple myeloma were given ixazomib-based chemotherapy, including 16 patients with relapsed/refractory multiple myeloma (RRMM group), 27 patients newly diagnosed multiple myeloma with serious adverse events initially treated with bortezomib (conversion treatment group). Single ixazomib or ixazomib-based 2- or 3-medicine regimens combined with dexamethasone and lenalidomide or thalidomide or cyclophosphamide were performed, and then the response and safety were assessed. RESULTS: The overall response rate (ORR) was 56.25%, and the rate of very good partial response (VGPR) was 18.75% in the RRMM group. Most effective patients were those with long-term recurrence. The ORR was 88.89% in the conversion treatment group, which was further improved compared with the ORR of 81.48% before the conversion, among which 59.26% had a further remission. The main adverse events included thrombocytopenia, leucopenia, diarrhea, asthenia, rash, joint pain, etc. CONCLUSIONS: Lxazomib is effective in treating the patients with later recurrence and the patients with serious adverse events initially treated with bortezomib. Lxazomib may not be effective in patients with recent relapse after bortezomib treatment. The adverse events are controllable.

Validity and Reliability of the Turkish Version of the Questionnaire for the Assessment of Dysphagia in Multiple Sclerosis.

INTRODUCTION: The aim of this study was to investigate the validity and reliability of the Turkish version of the Questionnaire for the Assessment of DYsphagia in MUltiple Sclerosis (DYMUS) that has been developed for evaluating dysphagia in patients with multiple sclerosis. METHODS: This methodological study was conducted in the neurology clinic and outpatient department of a training hospital between March 15 and September 15, 2015. The study included 117 patients aged 18 years and over who had a definite diagnosis of multiple sclerosis, could communicate in Turkish, and volunteered to be included. Data were collected using a descriptive information form, the DYMUS, and the Eating Assessment Tool (EAT-10). The scale was translated and back translated to determine the language validity, and a specialist was consulted to make sure the content was valid. We used the EAT-10 and Kurtzke's Expanded Disability Status Scale (EDSS) concurrently to test the criterion-related validity. The test-retest procedure was used at 1-week intervals for 37 patients in this study. Descriptive statistics, factor analysis, Kappa analysis, reliability analysis, and correlation analysis were used to analyze the data. RESULTS: Factor analysis revealed that the scale was bifactorial, and this was consistent with its original form. There were positive and statistically significant relationships between the DYMUS and EAT-10 (r=0.90, p<0.001) and the mean EDSS scores (r=0.49, p<0.001). The internal consistency of the total scale was high (Cronbach's alpha coefficient= 0.91). The Cronbach's alpha coefficients pertaining to dysphagia for solids and liquids were determined to be 0.88 and 0.83, respectively. The total scale and subscales demonstrated a high test-retest reliability (r=0.79-0.95, p<0.001). CONCLUSION: In this study, the Turkish version of the DYMUS was found to be a valid and reliable tool for evaluating dysphagia in patients with multiple sclerosis.

Prognostic significance of the red blood cell distribution width that maintain at high level following completion of first line therapy in mutiple myeloma patients.

To investigate the prognostic value of the red blood cell distribution width(RDW) recovery from low levels at diagnosis after completion of first line therapy in mutiple myeloma (MM)patients,we enrolled 78 consecutive patients with MM and followed up from 2005 to 2016 in our hospital. The RDW was measured following completion of first-line therapy.The log-rank test, univariate analysis, and Cox regression analysis were used to evaluate the relationship between RDW and survival. We found that patients with an RDW ≥ 15.5% at diagnosis, as well as at completion of first-line therapy, had significantly lower progression-free survival (PFS) and overall survival(OS) rates than those with an RDW < 15.5%(P < 0.05).Patients with RDW that maintained more than 15.5% upon completion of therapy showed a shorter OS (P < 0.05) and PFS (P < 0.05) compared with patients with an RDW that decreased to a lower level.The multivariate analysis showed that RDW ≥ 15.5% after the completion of first-line therapy were an independent prognostic marker of poorer OS (P = 0.044) and PFS (P = 0.034). Therefore,we demonstrated that RDW at diagnosis, as well as at completion of first-line therapy is an independent predictor for mutiple myeloma patients.RDW maintained at high level, irrespective of whether RDW decreased to the cutoff value predicted an unfavorable prognosis in patients with MM.

A Facile Strategy for Self-Healing Polyurethanes Containing Multiple Metal-Ligand Bonds.

A metal-ligand crosslinked internal self-healing polyurethane is developed using low-cost and commercially available compounds. The mechanical, photoluminescent, and self-healing properties can be governed by incorporating multiple metal-ligand crosslinks with weak and strong coordination bonds and varying the metal ion. In-situ attenuated total reflectance Fourier transform infrared spectroscopy reveals that the metal-ligand bond is cleaved during the damage process while metal ion is still coordinated with the ligand by stronger metal-pyridyl interaction. The multiple metal-ligand coordination facilitates the crosslinks to be fully reformed during the repairing process, leading to the superior self-healing property.

Modulating fluorescence anisotropy of dye-labeled DNA without involving mass amplification.

Fluorescence anisotropy, known as a simple, homogeneous and cost-effective analytical technology, is an invaluable technique for studying the micro-environmental changes of the dye associated with the molecular interactions. An in-depth understanding of the variables affecting the fluorescence anisotropy signal can facilitate better experimental designs to effectively improve the analytical performance. This work is a follow-up effort in evaluating the factors that can significantly influence fluorescence anisotropy. We systematically studied fluorescence anisotropy of dsDNA with the changing length based on dye-DNA interactions, with the fluorophores in the end-labeling, the middle-site-labeling, and multiple number of labeling manners. The fluorescence anisotropy value and the base-pair response dynamic range could be expanded by labeling the fluorophores in the middle of dsDNA and increasing the number of labels on dsDNA. The C overhang configuration in the end-labeling manner could enhance the fluorescence anisotropy signal but not expand the base-pair response range. Results from all the labeling fluorophores reinforced the leveling-off effect, i.e., the fluorescence anisotropy signal does not response to the increased length of the DNA duplex when the length is larger than a critical number of base pairs. These findings provide perspectives about choosing appropriate fluorescent dyes and labeling sites for simple and universal fluorescence anisotropy designs in various applications.

A new approach for deciphering between single and multiple accumulation events using intra-tooth isotopic variations: Application to the Middle Pleistocene bone bed of Schöningen 13 II-4.

It is often difficult to differentiate between archaeological bonebeds formed by one event such as a mass kill of a single herd, and those formed by multiple events that occurred over a longer period of time. The application of high temporal resolution studies such as intra-tooth isotopic profiles on archaeological mammal cohorts offers new possibilities for exploring this issue, allowing investigators to decipher between single and multiple accumulation events. We examined (18)O and (13)C isotopic variations from the enamel carbonate of 23 horse third molars from the Middle Pleistocene archaeological site of Schöningen. We employed a new approach to investigate processes of fossil accumulation that uses both bulk and intra-tooth isotopic variations and takes into account animal behavior, age at death and dental development to test the degree of isotopic affinity of animals from the same fossil assemblage. Oxygen and carbon isotope bulk values indicate that the horses from Schöningen 13 II-4 experienced relatively similar climatic and dietary regimes. Inter-individual differences of the bulk values of the horses sampled in the current study present nevertheless inter-individual variability similar to individuals from multi-layered localities. In addition, the intra-tooth isotopic variation of specimens of the same age at death seems to indicate that the studied cohort corresponds to a mix of individuals that recorded both similar and different isotopic histories. Finally, the conditions recorded in the isotopic signal shortly before death (i.e., for teeth not fully mineralized) varied between sampled individuals, suggesting possible differences in the seasonality of death. Considering those results, we discuss the possibility that the horses from Schöningen 13 II-4 correspond to an accumulation of different death events.

Multiple Sclerosis Outcome Assessments Consortium: Genesis and initial project plan.

The need for improved clinical outcome measures in multiple sclerosis trials has been recognized for two decades, but only recently has the Food and Drug Administration (FDA) created a pathway for qualification of new clinician-reported outcome (ClinRO) assessments. Additionally, drug development in multiple sclerosis (MS) has been extraordinarily active, with numerous disease-modifying drugs now on the market. This shifting therapeutic landscape, along with the unmet need for drugs to treat the progressive forms of MS and the changing expectations of clinicians, patients, and payers, have led to the call for more sensitive and meaningful disability progression measures. In response to these drivers, the Multiple Sclerosis Outcome Assessments Consortium (MSOAC) was launched. A public-private partnership, MSOAC aims to accelerate the development of new therapies for MS by generating new tools for measuring outcomes in clinical trials. At the first annual MSOAC/FDA meeting, a regulatory path was outlined for qualifying a new tool for assessing efficacy in registration trials of MS. The European Medicines Agency (EMA) and FDA will provide parallel consultation and review. The consensus approach with engagement by all of the stakeholders, prominently including patients with MS, should also increase acceptance of the measure by clinicians and patients.

Status of proteasome inhibitors in the treatment of multiple myeloma / 白血病·淋巴瘤

Multiple myeloma (MM) is a hematological malignancy caused by the clonal expansion ofbone marrow plasmacytes.It accounts for 10 ％ of all hematological malignancies.The proteasome,an intracellular enzyme complex that degrades ubiquitin-tagged proteins to regulate protein levels within the cell,plays an important role in maintaining cellular homeostasis.Proteasome inhibitors proved to be significantly effective in the clinical treatment of MM.In recent years,the application of the proteasome inhibitor has led to increased survival rates in MM patients.Bortezomib is the first proteasome inhibitor that has been approved by the US Food and Drug Administration due to its ability to reversibly inhibit the 26 s proteasome functions.Despite the fact that Bortezomib improves medical treatment,many patients experience difficulty responding to this drug and some patients who do respond eventually relapse.These results have led researchers to investigate new proteasome inhibitors with mechanisms different from those of Bortezomib.Some drugs that bind to the active site of the proteasome and irreversibly inhibit the complex have recently been developed and are currently being tested in advanced clinical trials.Here,we will elaborate on the proteasome inhibitors targeting MM and focus on newly discovered inhibitors that may overcome the resistance to Bortezomib.

Vital signs were monitored dur-hag treatment process. Results The vital signs of all patients` was stable, the levels of BUN,Scr and serum potassium decreased significantly after CVVH. The plasma concentrations of TNF-α,IL-1 and IL-8 gradually decreased. Conclusions CWH can improve the blood biochemical markers,remove inflammatory cytokines in plasma,stsblize the vital signs during treatment,which is suitable for patients with MODS.

A novel RET proto-oncogene mutation in a pedigree of multiple endocrine neoplasia type 2A / 中华内分泌代谢杂志

Objective To observe the clinical manifestation and the mode of RET proto-oncogene mutation in a pedigree of mutiple endocrine neoplasia type 2A (MEN2A). Methods Genomic DNA was extracted from the peripheral blood lymphocytes in 18 family members including 3 patients, then PCR was performed to amplify seven exons of the RET proto-oncogene, i. e. exon 8,10,11,13-16. The PCR products were directly sequenced to identify the RET mutation and then sequenced after subcloning to identify their heterozygosity. Results The male proband suffered from pheochromocytoma and medullary thyroid carcinoma since the age of 30; while his sibling sister was ill with pheochromocytoma, and his brother with medullary thyroid carcinoma. A novel heterozygous mutation, 1893-1895delCGA, was detected in exon 11 of the RET proto-oncogene in the 3 patients and the other 2 family members. Conclusion A novel heterozygous mutation of RET proto-oncogene, 1893-1895delCGA, seems to be the disease-causing mutation in the studied MEN2A family.
