    SOLAMEN综合征是一种罕见的,最近认识到的先天性综合征,其特征是涉及多个系统的进行性和肥大性疾病,包括节段性过度生长,脂肪瘤病,动静脉畸形(AVM)和表皮痣。根据文献,SOLAMEN综合征由杂合子PTEN突变引起。表型重叠使PTEN杂合突变相关疾病的临床鉴定变得复杂,使SOLAMEN的诊断更具挑战性。此外,SOLAMEN常表现为节段组织过度生长和血管畸形,增加误诊为kliple-trenaunay综合征或Parks-Weber综合征的可能性。这里,我们介绍了一个患有大头畸形的孩子,右胸有斑片状淋巴畸形,明显的皮下静脉曲张和毛细血管累及全身,左下肢过度生长,右侧下肢中部的表皮痣,右颅胸部入口处有一个大的AVM。根据典型的表型,患儿被诊断为SOLAMEN综合征.详细的临床,对SOLAMEN综合征进行影像学和遗传学诊断。下一代测序(NGS)数据显示,除了种系PTEN突变,还鉴定了PDGFRB变体。随后的超声心动图检查检测到潜在的心脏缺陷。我们建议考虑到AVM的进行性和心脏损害的潜在严重程度,常规超声心动图评估,建议对AVM进行影像学随访和适当的介入治疗.
    SOLAMEN syndrome is a rare, recently recognized congenital syndrome that is characterized by progressive and hypertrophic diseases involving multiple systems, including segmental overgrowth, lipomatosis, arteriovenous malformation (AVM) and epidermal nevus. According to literatures, SOLAMEN syndrome is caused by heterozygous PTEN mutation. Phenotypic overlap complicates the clinical identification of diseases associated with PTEN heterozygous mutations, making the diagnosis of SOLAMEN more challenging. In addition, SOLAMEN often presents with segmental tissue overgrowth and vascular malformations, increasing the possibility of misdiagnosis as klipple-trenaunay syndrome or Parks-Weber syndrome. Here, we present a case of a child presenting with macrocephaly, patchy lymphatic malformation on the right chest, marked subcutaneous varicosities and capillaries involving the whole body, overgrowth of the left lower limb, a liner epidermal nevus on the middle of the right lower limb, and a large AVM on the right cranial thoracic entrance. Based on the typical phenotypes, the child was diagnosed as SOLAMEN syndrome. detailed clinical, imaging and genetic diagnoses of SOLAMEN syndrome was rendered. Next-generation sequencing (NGS) data revealed that except for a germline PTEN mutation, a PDGFRB variant was also identified. A subsequent echocardiographic examination detected potential cardiac defects. We suggested that given the progressive nature of AVM and the potential severity of cardiac damage, regular echocardiographic evaluation, imaging follow-up and appropriate interventional therapy for AVM are recommended.

    尺杆手是一种罕见的上肢疾病,治疗取决于形态和功能损害的程度,与Dobyns的射线照相分类相关,木头,还有Bayne.本研究的目的是报告一例6岁男性患者,随访III型尺骨俱乐部手(总尺骨发育不良)。尽管最初很难操纵物体和执行日常任务,保守的物理治疗为日常生活提供力量增强和功能技能发展。我们得出的结论是,III型畸形患者可以通过康复得到适当的治疗,尽管他们需要门诊随访,直到达到骨骼成熟为止。因为动态畸形和新的功能限制可能导致需要矫正手术。
    Ulnar club hand is a rare condition of the upper limbs, for which treatment depends on the degree of morphological and functional impairment, correlating with the radiographic classification of Dobyns, Wood, and Bayne. The aim of the present study is to report a case of a 6-year-old male patient, followed up for type III ulnar club hand (total ulnar dysplasia). Despite the initial difficulty of manipulating objects and performing everyday tasks, conservative physical therapy treatment provided strength gain and development of functional skills for daily life. We conclude that patients with type III deformity can be properly managed with rehabilitation although they require outpatient follow-up until skeletal maturity is reached, as dynamic deformities and new functional limitations may lead to need for corrective surgeries.

    背景:上交叉综合症是一种肌肉失衡和姿势功能障碍的模式,可引起不适和疼痛。这项研究的目的是比较普拉提练习的效果,纠正练习,和亚历山大对13-16岁少女上交叉综合征的技术:一项为期六周的干预研究。
    方法:本研究是准实验,其统计人口包括13至16岁的女学生。有目的地选择45名被诊断患有上交叉综合征的学生作为样本,并随机分配到三组:普拉提练习(N=15),纠正练习(N=15),和亚历山大的技术(N=15)。参与者每节进行60分钟的练习,每周三次,还有六个星期.这项研究的目的是比较普拉提练习的效果,纠正练习,和亚历山大对13-16岁少女上交叉综合征的技术:一项为期六周的干预研究。这项研究于2023-09-19在伊朗临床试验注册中心(IRCT)进行了回顾性注册,以符合该杂志的政策。指定的试验登记号是IRCT20230810059106N1。
    结果:依赖t检验的结果表明,前头角明显减小(p=0.0001),圆肩(p=0.001),和后凸畸形(p=0.0001)作为矫正练习的结果。前头角也显著减小(p=0.0001),圆肩(p=0.002),和后凸畸形(p=0.001)6周后练习亚历山大的技术。然而,在普拉提练习的情况下,前头角显著减小(p=0.110),圆肩(p=0.598),未观察到后凸畸形(p=0.371)。单向方差分析显示,前头角存在显着差异(p=0.012),圆肩(p=0.013),和后凸畸形(p=0.009)。
    结论:亚历山大的技术和矫正练习对前头角的影响,圆形肩部,和后凸畸形几乎相似,比普拉提练习更有效。
    BACKGROUND: Upper Cross Syndrome is a pattern of muscle imbalance and postural dysfunction that can cause discomfort and pain. This study\'s objective was to compare the effects of Pilates exercises, corrective exercises, and Alexander\'s technique on upper cross syndrome in adolescent girls aged 13-16 years: a six-week intervention study.
    METHODS: The present study was Quasi-experimental, and its statistical population consisted of 13 to 16-year-old female students. Forty-five students who were diagnosed with upper cross syndrome were purposefully selected as samples and randomly assigned to three groups: Pilates exercises (N = 15), corrective exercises (N = 15), and Alexander\'s technique (N = 15). The participants performed exercises for 60 min per session, three sessions per week, and six weeks. This study\'s objective was to compare the effects of Pilates exercises, corrective exercises, and Alexander\'s technique on upper cross syndrome in adolescent girls aged 13-16 years: a six-week intervention study. This study was retrospectively registered in the Iranian Registry of Clinical Trials (IRCT) on 2023-09-19 to comply with the journal\'s policies. The assigned trial registration number is IRCT20230810059106N1.
    RESULTS: The results of the dependent t-test showed significant decreases in forward head angle (p = 0.0001), rounded shoulder (p = 0.001), and kyphosis (p = 0.0001) as a result of corrective exercises. There were also significant decreases in forward head angle (p = 0.0001), rounded shoulder (p = 0.002), and kyphosis (p = 0.001) after six weeks of practising Alexander\'s technique. However, in the case of Pilates exercises, a significant decrease in forward head angle (p = 0.110), rounded shoulder (p = 0.598), and kyphosis (p = 0.371) was not observed. The one-way analysis of variance revealed a significant difference in the forward head angle (p = 0.012), rounded shoulders (p = 0.013), and kyphosis (p = 0.009).
    CONCLUSIONS: The effect of Alexander\'s technique and corrective exercises on forward head angle, rounded shoulder, and kyphosis abnormalities was almost similar and more effective than pilates exercises.

    硒磷酸合成酶(SEPHS)在硒代谢中起着至关重要的作用。两个哺乳动物SEPHS旁系同源物,SEPHS1和SEPHS2与SEPHS具有高度的序列同一性和结构同源性。这里,我们报告了来自八个家庭的九个人发育迟缓,生长和喂养问题,低张力,和畸形特征,所有在SEPHS1中具有杂合错义变体。这些个体中有8个在SEPHS1的371位氨基酸处具有复发性变体(p。Arg371Trp,p.Arg371Gln,和p.Arg371Gly);已知这些变体中的七个是从头的。使用结构建模和生化测定来理解这些变体对SEPHS1功能的影响。我们发现残基Trp352的变体导致SEPHS1的C末端区域的局部结构变化,从而降低了酶的整体热稳定性。相比之下,暴露于溶剂的Arg371残基的变体不影响酶的稳定性和折叠,但可以调节SEPSH1与细胞因子的直接蛋白质-蛋白质相互作用,促进细胞增殖和发育.在神经元SH-SY5Y细胞中,我们评估了SEPHS1变异体对细胞增殖和ROS产生的影响,并研究了编码应激相关硒蛋白的基因的mRNA表达水平.我们的发现提供了证据,表明鉴定的SEPHS1变体通过调节ROS稳态来增强细胞增殖。我们的研究支持SEPHS1在人类发育中起关键作用的假设,并为进一步研究SEPHS1采用的分子机制提供了基础。此外,我们的数据提示,SEPHS1变异与神经发育障碍相关.
    Selenophosphate synthetase (SEPHS) plays an essential role in selenium metabolism. Two mammalian SEPHS paralogues, SEPHS1 and SEPHS2, share high sequence identity and structural homology with SEPHS. Here, we report nine individuals from eight families with developmental delay, growth and feeding problems, hypotonia, and dysmorphic features, all with heterozygous missense variants in SEPHS1. Eight of these individuals had a recurrent variant at amino acid position 371 of SEPHS1 (p.Arg371Trp, p.Arg371Gln, and p.Arg371Gly); seven of these variants were known to be de novo. Structural modeling and biochemical assays were used to understand the effect of these variants on SEPHS1 function. We found that a variant at residue Trp352 results in local structural changes of the C-terminal region of SEPHS1 that decrease the overall thermal stability of the enzyme. In contrast, variants of a solvent-exposed residue Arg371 do not impact enzyme stability and folding but could modulate direct protein-protein interactions of SEPSH1 with cellular factors in promoting cell proliferation and development. In neuronal SH-SY5Y cells, we assessed the impact of SEPHS1 variants on cell proliferation and ROS production and investigated the mRNA expression levels of genes encoding stress-related selenoproteins. Our findings provided evidence that the identified SEPHS1 variants enhance cell proliferation by modulating ROS homeostasis. Our study supports the hypothesis that SEPHS1 plays a critical role during human development and provides a basis for further investigation into the molecular mechanisms employed by SEPHS1. Furthermore, our data suggest that variants in SEPHS1 are associated with a neurodevelopmental disorder.

    人类的过度生长和智力障碍障碍以长度/身高和/或头围≥平均值以上2个标准偏差以及智力障碍和行为合并症为代表,包括自闭症和焦虑。Tatton-Brown-Rahman综合征是一种由DNA甲基转移酶3A(DNMT3A)基因的杂合错义突变引起的过度生长和智力障碍。已经在Tatton-Brown-Rahman综合征患者中鉴定了许多DNMT3A突变,并且可能与临床表现的不同表型严重程度有关。两个这样的突变是导致严重和轻度表型的R882H和P904L突变。分别。具有旁系同源突变的小鼠(Dnmt3aP900L/和Dnmt3aR878H/)在其长骨中表现出过度生长(例如,股骨,肱骨),但其骨骼过度生长的机制尚不清楚。这项研究的目的是表征Tatton-Brown-Rahman综合征小鼠模型中的骨骼表型,并确定参与骨骼过度生长表型的潜在细胞机制。我们报道,具有Dnmt3aP900L/+或Dnmt3aR878H/+突变的成熟小鼠表现出胫骨过度生长,皮质骨变薄,和削弱骨的力学性能。与对照动物相比,Dnmt3aR878H/+突变体还含有较大的骨髓脂肪细胞,而Dnmt3aP900L/+突变体没有显示脂肪细胞表型。为了了解调节这些表型的潜在细胞机制,生长板软骨细胞,成骨细胞,使用定量静态组织形态计量学和动态组织形态计量学在幼年突变小鼠中评估破骨细胞。突变幼鼠的胫骨生长板显得较厚,但未观察到股骨中骨干的成骨细胞活性或破骨细胞数量的变化。这些研究揭示了小鼠中与Tatton-Brown-Rahman综合征相关的新骨骼表型,并提供了扩展对患有这种疾病的患者的临床评估以包括骨密度和质量测试的基本原理。这些发现也可能为表现出过度生长和智力障碍表型的其他小鼠模型的骨骼表征提供信息。
    Overgrowth and intellectual disability disorders in humans are typified by length/height and/or head circumference ≥ 2 standard deviations above the mean as well as intellectual disability and behavioral comorbidities, including autism and anxiety. Tatton-Brown-Rahman Syndrome is one type of overgrowth and intellectual disability disorder caused by heterozygous missense mutations in the DNA methyltransferase 3A (DNMT3A) gene. Numerous DNMT3A mutations have been identified in Tatton-Brown-Rahman Syndrome patients and may be associated with varying phenotype severities of clinical presentation. Two such mutations are the R882H and P904L mutations which result in severe and mild phenotypes, respectively. Mice with paralogous mutations (Dnmt3aP900L/+ and Dnmt3aR878H/+) exhibit overgrowth in their long bones (e.g., femur, humerus), but the mechanisms responsible for their skeletal overgrowth remain unknown. The goal of this study is to characterize skeletal phenotypes in mouse models of Tatton-Brown-Rahman Syndrome and identify potential cellular mechanisms involved in the skeletal overgrowth phenotype. We report that mature mice with the Dnmt3aP900L/+ or Dnmt3aR878H/+ mutation exhibit tibial overgrowth, cortical bone thinning, and weakened bone mechanical properties. Dnmt3aR878H/+ mutants also contain larger bone marrow adipocytes while Dnmt3aP900L/+ mutants show no adipocyte phenotype compared to control animals. To understand the potential cellular mechanisms regulating these phenotypes, growth plate chondrocytes, osteoblasts, and osteoclasts were assessed in juvenile mutant mice using quantitative static histomorphometry and dynamic histomorphometry. Tibial growth plates appeared thicker in mutant juvenile mice, but no changes were observed in osteoblast activity or osteoclast number in the femoral mid-diaphysis. These studies reveal new skeletal phenotypes associated with Tatton-Brown-Rahman Syndrome in mice and provide a rationale to extend clinical assessments of patients with this condition to include bone density and quality testing. These findings may be also informative for skeletal characterization of other mouse models presenting with overgrowth and intellectual disability phenotypes.

    FRY样转录共激活因子(FRYL)属于从酵母到人类在进化上保守的Furry蛋白家族。FRYL在哺乳动物中的功能在很大程度上是未知的,FRYL中的变体以前没有与孟德尔疾病相关。这里,我们报告了14个在FRYL中具有杂合变体的个体,这些个体存在发育迟缓,智力残疾,变形特征,和其他多个系统的先天性异常。在除了一个个体之外的所有个体中从头确认变体。人类遗传数据表明FRYL不能耐受功能丧失(LoF)。我们发现苍蝇FRYL直系同源物,毛茸茸的(油炸),在多个组织中表达,包括中枢神经系统,它存在于神经元中,但不存在于神经胶质中。纯合fryLoF突变在各个发育阶段都是致命的,突变克隆中鱼苗的丢失会导致翅膀和复眼的缺陷。接下来,我们使用fry门金等位基因对在受影响的个体中发现的五个错义变体中的四个进行了建模。一种变体表现为严重的LoF变体,而另外两个则表现为部分LoF变体。一种变体不会在苍蝇中引起任何可观察到的缺陷,相应的人类变异没有被证实是从头的,这表明这是一个意义不确定的变体。总之,我们的研究结果支持fry是果蝇正常发育所必需的,FRYL中的LoF变异体因单倍体功能不全而导致具有发育和神经系统症状的显性疾病.
    FRY-like transcription coactivator (FRYL) belongs to a Furry protein family that is evolutionarily conserved from yeast to humans. The functions of FRYL in mammals are largely unknown, and variants in FRYL have not previously been associated with a Mendelian disease. Here, we report fourteen individuals with heterozygous variants in FRYL who present with developmental delay, intellectual disability, dysmorphic features, and other congenital anomalies in multiple systems. The variants are confirmed de novo in all individuals except one. Human genetic data suggest that FRYL is intolerant to loss of function (LoF). We find that the fly FRYL ortholog, furry (fry), is expressed in multiple tissues, including the central nervous system where it is present in neurons but not in glia. Homozygous fry LoF mutation is lethal at various developmental stages, and loss of fry in mutant clones causes defects in wings and compound eyes. We next modeled four out of the five missense variants found in affected individuals using fry knockin alleles. One variant behaves as a severe LoF variant, whereas two others behave as partial LoF variants. One variant does not cause any observable defect in flies, and the corresponding human variant is not confirmed to be de novo, suggesting that this is a variant of uncertain significance. In summary, our findings support that fry is required for proper development in flies and that the LoF variants in FRYL cause a dominant disorder with developmental and neurological symptoms due to haploinsufficiency.

    DHCR7和SC5D是胆固醇生物合成的关键酶,它们的基因突变与发育障碍有关,以颅面畸形为特征。我们最近报道了Dhcr7或Sc5d的缺失导致成骨细胞分化失败。然而,目前尚不清楚DHCR7或SC5D功能丧失在多大程度上影响颅面骨骼形成.这里,使用显微计算机断层扫描(μCT),我们发现Dhcr7-/-和Sc5d-/-小鼠的骨表型以特定位置的方式不同。例如,在Sc5d-/-小鼠中,尽管颅面骨骼整体受到影响,一些骨段,比如前颌骨的前部,额骨的前后长度,和下颌骨的主体,与WT对照相比没有显著差异。相比之下,在Dhcr7-/-小鼠中,虽然颅面骨骼没有受到太大影响,额骨的宽度和体积更大,上颌骨和腭骨发育不良,与WT对照相比。有趣的是,Dhcr7-/-小鼠的下颌骨主要在髁突区域受到影响,不是尸体。因此,这些结果帮助我们了解Dhcr7-/-和Sc5d-/-小鼠中哪些骨骼以及它们受到胆固醇代谢异常的影响。
    DHCR7 and SC5D are enzymes crucial for cholesterol biosynthesis, and mutations in their genes are associated with developmental disorders, which are characterized by craniofacial deformities. We have recently reported that a loss of either Dhcr7 or Sc5d results in a failure in osteoblast differentiation. However, it remains unclear to what extent a loss of function in either DHCR7 or SC5D affects craniofacial skeletal formation. Here, using micro computed tomography (μCT), we found that the bone phenotype differs in Dhcr7-/- and Sc5d-/- mice in a location-specific fashion. For instance, in Sc5d-/- mice, although craniofacial bones were overall affected, some bone segments, such as the anterior part of the premaxilla, the anterior-posterior length of the frontal bone, and the main body of the mandible, did not present significant differences compared to WT controls. By contrast, in Dhcr7-/- mice, while craniofacial bones were not much affected, the frontal bone was larger in width and volume, and the maxilla and palatine bone were hypoplastic, compared to WT controls. Interestingly the mandible in Dhcr7-/- mice was mainly affected at the condylar region, not the body. Thus, these results help us understand which bones and how greatly they are affected by cholesterol metabolism aberrations in Dhcr7-/- and Sc5d-/- mice.

    Cri-du-chat综合征是一种罕见的遗传性疾病,由于5号染色体短臂的缺失(5p-)。其发病率从1/15000到1/50000活产。这是一个来自非近亲婚姻的一天大的男性新生儿,第一次怀孕没有并发症,出生体重为2295g。临床检查显示:颅面畸形伴远大和小头畸形,低张力,吸力差和马蹄内翻足在右边标记得更多,其余的检查并不引人注目。住院期间,观察到模仿猫喵喵叫的高调单色叫声。经荧光原位杂交证实临床诊断,显示5号染色体短臂的缺失(5p15.2)。基本的畸形检查没有任何其他异常。新生儿的高音调单色哭声与颅面畸形的关联应表明需要进行细胞遗传学研究,特别是在定点杂交中的荧光。
    Cri-du-chat syndrome is a rare genetic disorder, due to a deletion of the short arm of chromosome 5 (5p-). Its incidence is ranging from 1/15000 to 1/50000 live births. This was a one-day-old male newborn from a non-consanguineous marriage, the first pregnancy uncomplicated and carried to term with a birth weight of 2295g. Clinical examination revealed: craniofacial dysmorphism with hypertelorism and microcephaly, hypotonia, poor suction and clubfoot more marked on the right, the rest of the examination was unremarkable. During hospitalization, a high-pitched monochromatic cry mimicking a cat\'s meow was observed. The clinical diagnosis was confirmed by fluorescence in situ hybridization, showing a deletion of the short arm of chromosome 5 (5p15.2). The basic malformative work-up came back without any other abnormalities. The association of a high-pitched monochromatic cry with craniofacial dysmorphism in a newborn should indicate the need for cytogenetic study, in particular fluorescence in siti hybridization.

    背景:半面巨大儿(HFM,OMIM164210)是一种复杂且高度异质性的疾病。ForkheadBOXI3(FOXI3)是HFM的易感基因,Foxi3功能丧失的小鼠确实表现出与颅面畸形相似的表型。然而,FOXI3缺乏引起HFM的具体发病机制至今仍不清楚。
    方法:在本研究中,我们首先构建了Foxi3缺乏症(Foxi3-/-)小鼠模型来验证Foxi3-/-小鼠的颅面表型,然后使用RNAseq数据进行基因差异表达分析来筛选候选致病基因,并采用实时定量PCR进行基因表达验证分析。
    结果:通过观察Foxi3-/-小鼠的表型,我们发现存在颅面畸形。综合生物信息学分析结果提示,Foxi3缺乏引起的颅面畸形可能与PI3K-Akt信号通路有关。实时定量PCR结果显示,FOxi3-/-小鼠体内PI3K-Akt信号通路相关基因Akt2的表达明显升高。
    结论:FOxi3缺乏引起的颅面畸形可能与Akt2和PI3K-Akt信号通路的表达有关。本研究为了解FOXI3的功能及FOXI3功能障碍引起的相关颅面部畸形的发病机制和治疗奠定了基础。
    BACKGROUND: Hemifacial macrosomia (HFM, OMIM 164210) is a complex and highly heterogeneous disease. FORKHEAD BOX I3 (FOXI3) is a susceptibility gene for HFM, and mice with loss of function of Foxi3 did exhibit a phenotype similar to craniofacial dysmorphism. However, the specific pathogenesis of HFM caused by FOXI3 deficiency remains unclear till now.
    METHODS: In this study, we first constructed a Foxi3 deficiency (Foxi3-/- ) mouse model to verify the craniofacial phenotype of Foxi3-/- mice, and then used RNAseq data for gene differential expression analysis to screen candidate pathogenic genes, and conducted gene expression verification analysis using quantitative real-time PCR.
    RESULTS: By observing the phenotype of Foxi3-/- mice, we found that craniofacial dysmorphism was present. The results of comprehensive bioinformatics analysis suggested that the craniofacial dysmorphism caused by Foxi3 deficiency may be involved in the PI3K-Akt signaling pathway. Quantitative real-time PCR results showed that the expression of PI3K-Akt signaling pathway-related gene Akt2 was significantly increased in Foxi3-/- mice.
    CONCLUSIONS: The craniofacial dysmorphism caused by the deficiency of Foxi3 may be related to the expression of Akt2 and PI3K-Akt signaling pathway. This study laid a foundation for understanding the function of FOXI3 and the pathogenesis and treatment of related craniofacial dysmorphism caused by FOXI3 dysfunction.
