Abstract
Bryant-Li-Bhoj syndrome (BLBS), which became OMIM-classified in 2022 (OMIM: 619720, 619721), is caused by germline variants in the two genes that encode histone H3.3 (H3-3A/H3F3A and H3-3B/H3F3B) [1-4]. This syndrome is characterized by developmental delay/intellectual disability, craniofacial anomalies, hyper/hypotonia, and abnormal neuroimaging [1, 5]. BLBS was initially categorized as a progressive neurodegenerative syndrome caused by de novo heterozygous variants in either H3-3A or H3-3B [1-4]. Here, we analyze the data of the 58 previously published individuals along 38 unpublished, unrelated individuals. In this larger cohort of 96 people, we identify causative missense, synonymous, and stop-loss variants. We also expand upon the phenotypic characterization by elaborating on the neurodevelopmental component of BLBS. Notably, phenotypic heterogeneity was present even amongst individuals harboring the same variant. To explore the complex phenotypic variation in this expanded cohort, the relationships between syndromic phenotypes with three variables of interest were interrogated: sex, gene containing the causative variant, and variant location in the H3.3 protein. While specific genotype-phenotype correlations have not been conclusively delineated, the results presented here suggest that the location of the variants within the H3.3 protein and the affected gene (H3-3A or H3-3B) contribute more to the severity of distinct phenotypes than sex. Since these variables do not account for all BLBS phenotypic variability, these findings suggest that additional factors may play a role in modifying the phenotypes of affected individuals. Histones are poised at the interface of genetics and epigenetics, highlighting the potential role for gene-environment interactions and the importance of future research.

Abstract
INTRODUCTION Rapid genomic sequencing (rGS) in critically ill infants with suspected genetic disorders has high diagnostic and clinical utility. However, rGS has primarily been available at large referral centres with the resources and expertise to offer state-of-the-art genomic care. Critically ill infants from racial and ethnic minority and/or low-income populations disproportionately receive care in safety-net and/or community settings lacking access to state-of-the-art genomic care, contributing to unacceptable health equity gaps. VIrtual GenOme CenteR is a 'proof-of-concept' implementation science study of an innovative delivery model for genomic care in safety-net neonatal intensive care units (NICUs). METHODS AND ANALYSIS We developed a virtual genome centre at a referral centre to remotely support safety-net NICU sites predominantly serving racial and ethnic minority and/or low-income populations and have limited to no access to rGS. Neonatal providers at each site receive basic education about genomic medicine from the study team and identify eligible infants. The study team enrols eligible infants (goal n of 250) and their parents and follows families for 12 months. Enrolled infants receive rGS, the study team creates clinical interpretive reports to guide neonatal providers on interpreting results, and neonatal providers return results to families. Data is collected via (1) medical record abstraction, (2) surveys, interviews and focus groups with neonatal providers and (3) surveys and interviews with families. We aim to examine comprehensive implementation outcomes based on the Proctor Implementation Framework using a mixed methods approach. ETHICS AND DISSEMINATION This study is approved by the institutional review board of Boston Children's Hospital (IRB-P00040496) and participating sites. Participating families are required to provide electronic written informed consent and neonatal provider consent is implied through the completion of surveys. The results will be disseminated via peer-reviewed publications and data will be made accessible per National Institutes of Health (NIH) policies. TRIAL REGISTRATION NUMBER NCT05205356/clinicaltrials.gov.

Abstract
Pre-mRNA splicing is a highly coordinated process. While its dysregulation has been linked to neurological deficits, our understanding of the underlying molecular and cellular mechanisms remains limited. We implicated pathogenic variants in U2AF2 and PRPF19, encoding spliceosome subunits in neurodevelopmental disorders (NDDs), by identifying 46 unrelated individuals with 23 de novo U2AF2 missense variants (including 7 recurrent variants in 30 individuals) and 6 individuals with de novo PRPF19 variants. Eight U2AF2 variants dysregulated splicing of a model substrate. Neuritogenesis was reduced in human neurons differentiated from human pluripotent stem cells carrying two U2AF2 hyper-recurrent variants. Neural loss of function (LoF) of the Drosophila orthologs U2af50 and Prp19 led to lethality, abnormal mushroom body (MB) patterning, and social deficits, which were differentially rescued by wild-type and mutant U2AF2 or PRPF19. Transcriptome profiling revealed splicing substrates or effectors (including Rbfox1, a third splicing factor), which rescued MB defects in U2af50-deficient flies. Upon reanalysis of negative clinical exomes followed by data sharing, we further identified 6 patients with NDD who carried RBFOX1 missense variants which, by in vitro testing, showed LoF. Our study implicates 3 splicing factors as NDD-causative genes and establishes a genetic network with hierarchy underlying human brain development and function.

Abstract
Neurodevelopmental disorders (NDDs) result from highly penetrant variation in hundreds of different genes, some of which have not yet been identified. Using the MatchMaker Exchange, we assembled a cohort of 27 individuals with rare, protein-altering variation in the transcriptional coregulator ZMYM3, located on the X chromosome. Most (n = 24) individuals were males, 17 of which have a maternally inherited variant; six individuals (4 male, 2 female) harbor de novo variants. Overlapping features included developmental delay, intellectual disability, behavioral abnormalities, and a specific facial gestalt in a subset of males. Variants in almost all individuals (n = 26) are missense, including six that recurrently affect two residues. Four unrelated probands were identified with inherited variation affecting Arg441, a site at which variation has been previously seen in NDD-affected siblings, and two individuals have de novo variation resulting in p.Arg1294Cys (c.3880C>T). All variants affect evolutionarily conserved sites, and most are predicted to damage protein structure or function. ZMYM3 is relatively intolerant to variation in the general population, is widely expressed across human tissues, and encodes a component of the KDM1A-RCOR1 chromatin-modifying complex. ChIP-seq experiments on one variant, p.Arg1274Trp, indicate dramatically reduced genomic occupancy, supporting a hypomorphic effect. While we are unable to perform statistical evaluations to definitively support a causative role for variation in ZMYM3, the totality of the evidence, including 27 affected individuals, recurrent variation at two codons, overlapping phenotypic features, protein-modeling data, evolutionary constraint, and experimentally confirmed functional effects strongly support ZMYM3 as an NDD-associated gene.

Abstract
BACKGROUND Expert recommendations propose the WHO Disability Assessment Schedule (WHODAS) 2.0 as a core outcome measure in surgical studies, yet data on its long-term measurement properties remain limited. These were evaluated in a secondary analysis of the Measurement of Exercise Tolerance before Surgery (METS) prospective cohort. METHODS Participants were adults (40 years of age or older) who underwent inpatient non-cardiac surgery. The 12-item WHODAS and EQ-5DTM-3L questionnaires were administered preoperatively (in person) and 1 year postoperatively (by telephone). Responsiveness was characterized using standardized response means (SRMs) and correlation coefficients between change scores. Construct validity was evaluated using correlation coefficients between 1-year scores and comparisons of WHODAS scores across clinically relevant subgroups. RESULTS The analysis included 546 patients. There was moderate correlation between changes in WHODAS and various EQ-5DTM subscales. The strongest correlation was between changes in WHODAS and changes in the functional domains of the EQ-5D-3L-for example, mobility (Spearman's rho 0.40, 95 per cent confidence interval [c.i.] 0.32 to 0.48) and usual activities (rho 0.45, 95 per cent c.i. 0.30 to 0.52). When compared across quartiles of EQ-5D index change, median WHODAS scores followed expected patterns of change. In subgroups with expected functional status changes, the WHODAS SRMs ranged from 'small' to 'large' in the expected directions of change. At 1 year, the WHODAS demonstrated convergence with the EQ-5D-3L functional domains, and good discrimination between patients with expected differences in functional status. CONCLUSION The WHODAS questionnaire has construct validity and responsiveness as a measure of functional status at 1 year after major surgery.

Abstract
Chromatin is essentially an array of nucleosomes, each of which consists of the DNA double-stranded fiber wrapped around a histone octamer. This organization supports cellular processes such as DNA replication, DNA transcription, and DNA repair in all eukaryotes. Human histone H4 is encoded by fourteen canonical histone H4 genes, all differing at the nucleotide level but encoding an invariant protein. Here, we present a cohort of 29 subjects with de novo missense variants in six H4 genes (H4C3, H4C4, H4C5, H4C6, H4C9, and H4C11) identified by whole-exome sequencing and matchmaking. All individuals present with neurodevelopmental features of intellectual disability and motor and/or gross developmental delay, while non-neurological features are more variable. Ten amino acids are affected, six recurrently, and are all located within the H4 core or C-terminal tail. These variants cluster to specific regions of the core H4 globular domain, where protein-protein interactions occur with either other histone subunits or histone chaperones. Functional consequences of the identified variants were evaluated in zebrafish embryos, which displayed abnormal general development, defective head organs, and reduced body axis length, providing compelling evidence for the causality of the reported disorder(s). While multiple developmental syndromes have been linked to chromatin-associated factors, missense-bearing histone variants (e.g., H3 oncohistones) are only recently emerging as a major cause of pathogenicity. Our findings establish a broader involvement of H4 variants in developmental syndromes.

Abstract
Loss-of-function variants in PHD Finger Protein 8 (PHF8) cause Siderius X-linked intellectual disability (ID) syndrome, hereafter called PHF8-XLID. PHF8 is a histone demethylase that is important for epigenetic regulation of gene expression. PHF8-XLID is an under-characterized disorder with only five previous reports describing different PHF8 predicted loss-of-function variants in eight individuals. Features of PHF8-XLID include ID and craniofacial dysmorphology. In this report we present 16 additional individuals with PHF8-XLID from 11 different families of diverse ancestry. We also present five individuals from four different families who have ID and a variant of unknown significance in PHF8 with no other explanatory variant in another gene. All affected individuals exhibited developmental delay and all but two had borderline to severe ID. Of the two who did not have ID, one had dyscalculia and the other had mild learning difficulties. Craniofacial findings such as hypertelorism, microcephaly, elongated face, ptosis, and mild facial asymmetry were found in some affected individuals. Orofacial clefting was seen in three individuals from our cohort, suggesting that this feature is less common than previously reported. Autism spectrum disorder and attention deficit hyperactivity disorder, which were not previously emphasized in PHF8-XLID, were frequently observed in affected individuals. This series expands the clinical phenotype of this rare ID syndrome caused by loss of PHF8 function.

Abstract
Abstract
Introduction
Those wishing to pursue a career in surgery will be aware of stereotypes that exist within each specialty, including how long it takes to attain a certificate of completion of training (CCT). These perceptions are often historic, and whilst may be based on elements of truth, are rarely backed by robust data. Oral & maxillofacial surgery (OMFS) for example is plagued by the stigma of necessitating a second degree which gives the assumption the age of being appointed a consultant is somewhat above average. We aim to dispel (or prove, depending on one’s predisposition) such myths by analysing the age of surgeons when appointed to the General Medical Council’s specialist list.
Method
Information on the age of entry onto the surgical specialist lists between 1997 and 2018 was obtained from the General Medical Council (GMC). Data was suitably statistically analysed.
Results
19,135 surgeons joined surgical specialist lists during the study period. General and trauma and orthopaedic surgery accounted for 60% of all surgeons (n = 11,444). The age on joining surgical specialist lists ranged from 27–83 years, with a mean of 41.4 years. Neurosurgeons most frequently joined the specialist list in the youngest age bracket. OMF surgeons, along with their cardiothoracic and vascular colleagues, are joint eldest by 1.3 years.
Conclusions
Since the creation of the specialist list, training has seen several upheavals. This data shows that despite each specialty’s specific requirements and individuals’ varying paths, there is little difference in the age when the consultant destination is reached.

Abstract
ZusammenfassungDer La Trobe Communication Questionnaire (LCQ) ist ein Verfahren, um Veränderungen des Gesprächsverhaltens nach Schädelhirntrauma zu erheben. Die vorliegende Version des LCQ ist im deutschsprachigen Raum derzeit der einzige psychometrisch untersuchte Fragebogen, mit dem kognitive Kommunikationsstörungen bei SHT sowohl aus der Perspektive von Betroffenen als auch Bezugspersonen bewertet werden können. Ziel der direkten Replikationsstudie war es zu prüfen, ob die deutsche Adaptation des LCQ zu vergleichbaren Ergebnissen in der Selbst- und Fremdeinschätzung führt wie die australische Originalversion. In dieser Pilotstudie wurde an einer Stichprobe von 160 Probanden (= 80 Dyaden) überprüft, ob sich bei neurologisch gesunden Probanden in Bezug auf die Selbst- und Fremdeinschätzung ähnliche Resultate zeigen wie in der Originalversion: Die Selbstauskunft sollte im Vergleich zur Fremdauskunft kritischer ausfallen, was sich in einem höheren Punktwert im LCQ widerspiegeln sollte. Zudem sollten keine signifikanten Mittelwertsunterschiede für die Selbst- bzw. Fremdbeurteilung zwischen der Originalversion und der deutschsprachigen Version vorliegen. In der vorliegenden Studie konnten die wichtigsten Ergebnisse der Originalstudie repliziert werden, was die Validität des LCQ untermauert.

Abstract
Endurance is one of the fastest growing equestrian disciplines worldwide. Races are long distance competitions (40-160 km), organised into loops, over variable terrain usually within one day. Horse and rider combinations in endurance races have to complete the course in good condition whilst also aiming to win. Horse welfare is paramount within the sport and horses are required to ‘pass’ a veterinary check prior to racing, after each loop of the course and at the end of the race. Despite the health, fitness and welfare of both athletes within the horse-rider dyad being essential to achieve success, few equivalent measures assessing the wellbeing of the endurance rider are implemented. This review considers evidence from ultra-endurance sports and rider performance in other equestrian disciplines, to consider physiological and psychological strategies the endurance rider could use to enhance their competition performance. Successful endurance riding requires an effective partnership to be established between horse and rider. Within this partnership, adequate rider health and fitness are key to optimal decision-making to manage the horse effectively during training and competition, but just as importantly riders should manage themselves as an athlete. Targeted management for superior rider performance can underpin more effective decision-making promoting ethical equitation practices and optimising competition performance. Therefore, the responsible and competitive endurance rider needs to consider how they prepare themselves adequately for participation in the sport. This should include engaging in appropriate physiological training for fitness and musculoskeletal strength and conditioning. Alongside planning nutritional strategies to support rider performance in training and within the pre-, peri- and post-competition periods to promote superior physical and cognitive performance, and prevent injury. By applying an evidence informed approach to self-management, the endurance athlete will support the horse and rider partnership to achieve to their optimal capacity, whilst maximising both parties physical and psychological wellbeing.

Abstract
PURPOSE In this study we investigate the disease etiology in 12 patients with de novo variants in FAR1 all resulting in an amino acid change at position 480 (p.Arg480Cys/His/Leu). METHODS Following next-generation sequencing and clinical phenotyping, functional characterization was performed in patients' fibroblasts using FAR1 enzyme analysis, FAR1 immunoblotting/immunofluorescence, and lipidomics. RESULTS All patients had spastic paraparesis and bilateral congenital/juvenile cataracts, in most combined with speech and gross motor developmental delay and truncal hypotonia. FAR1 deficiency caused by biallelic variants results in defective ether lipid synthesis and plasmalogen deficiency. In contrast, patients' fibroblasts with the de novo FAR1 variants showed elevated plasmalogen levels. Further functional studies in fibroblasts showed that these variants cause a disruption of the plasmalogen-dependent feedback regulation of FAR1 protein levels leading to uncontrolled ether lipid production. CONCLUSION Heterozygous de novo variants affecting the Arg480 residue of FAR1 lead to an autosomal dominant disorder with a different disease mechanism than that of recessive FAR1 deficiency and a diametrically opposed biochemical phenotype. Our findings show that for patients with spastic paraparesis and bilateral cataracts, FAR1 should be considered as a candidate gene and added to gene panels for hereditary spastic paraplegia, cerebral palsy, and juvenile cataracts.

Abstract
SWI/SNF-related intellectual disability disorders (SSRIDDs) are rare neurodevelopmental disorders characterized by developmental disability, coarse facial features, and fifth digit/nail hypoplasia that are caused by pathogenic variants in genes that encode for members of the SWI/SNF (or BAF) family of chromatin remodeling complexes. We have identified 12 individuals with rare variants (10 loss-of-function, 2 missense) in the BICRA (BRD4 interacting chromatin remodeling complex-associated protein) gene, also known as GLTSCR1, which encodes a subunit of the non-canonical BAF (ncBAF) complex. These individuals exhibited neurodevelopmental phenotypes that include developmental delay, intellectual disability, autism spectrum disorder, and behavioral abnormalities as well as dysmorphic features. Notably, the majority of individuals lack the fifth digit/nail hypoplasia phenotype, a hallmark of most SSRIDDs. To confirm the role of BICRA in the development of these phenotypes, we performed functional characterization of the zebrafish and Drosophila orthologs of BICRA. In zebrafish, a mutation of bicra that mimics one of the loss-of-function variants leads to craniofacial defects possibly akin to the dysmorphic facial features seen in individuals harboring putatively pathogenic BICRA variants. We further show that Bicra physically binds to other non-canonical ncBAF complex members, including the BRD9/7 ortholog, CG7154, and is the defining member of the ncBAF complex in flies. Like other SWI/SNF complex members, loss of Bicra function in flies acts as a dominant enhancer of position effect variegation but in a more context-specific manner. We conclude that haploinsufficiency of BICRA leads to a unique SSRIDD in humans whose phenotypes overlap with those previously reported.

Abstract
Training in UK surgery has changed dramatically since 1995, from a relative lack of structure to time-limited and highly documented programmes. Training in oral and maxillofacial surgery (OMFS) has shared these changes and included some significant changes of its own. Minutes from the OMFS Specialty Advisory Committee (SAC) were reviewed over the last 25 years to record the number and location of newly approved posts. The General Medicine Council's (GMC) OMFS specialist list in 2019 was combined with the records of OMFS specialists' dental qualifications held by the General Dental Council (GDC) and augmented from a database of OMFS trainees and consultants in the UK. Data on demographics, location, and nature of the first medical or dental degree were noted for analysis. A total of 691 OMFS specialists and trainees were identified from GMC, OMFS SAC and consultant databases. Of these, 12 consultants held only dental qualification/registration. First degree data could not be obtained for 12 specialists (all male). A further 20 OMFS specialists, whose training was outside the UK, were also excluded from further analysis. In 1995 there were 95 national training posts, by 2013 there were 150. Over the last quarter of a century, there has been an increase in medicine first trainees, an increase in female trainees and specialists, and a relative decrease in OMFS trainees from the Indian subcontinent. The varied origins of the OMFS workforce has contributed to greater diversity and inclusion within the specialty. In the UK, OMFS appears to have produced the correct number of specialists whilst maintaining a high standard of training. The next change in OMFS training programmes is to deliver The Postgraduate Medical Education and Training Board's (PMETB) recommendations. As we move to achieve this it is imperative that as new doors open, we do not close others.

Abstract
Understanding workforce pressures within surgery is an inexact science. This paper assembles evidence regarding oral and maxillofacial surgery (OMFS) consultant appointments in the UK and plans for prospective data collection in the future. Information about the number of OMFS specialists joining the UK specialist list was obtained from the General Medical Council and compared to a database of substantive OMFS consultant posts. OMFS consultants were asked to contribute information about their training programmes and consultant appointments (date, interview experience, and sub-specialty interest). This information was collated on Excel© and analysed using WinStat©. Data on OMFS consultant posts advertised in 'NHS Jobs' and the British Medical Journal were collected. The mean (SD) number of specialists joining the specialist list per year is 24.1 (5.2) with a median of 24 and a range of 15 - 36. The number of trainees completing training and numbers joining the OMFS specialist list are in balance at present. The median delay between OMFS specialist listing and appointment as a consultant was 72 days and mean of 169 with the 25th centile of five days, standard deviation of 239 days and maximum of 5.2 years. Of those returning data, 135 (47%) candidates were the sole interviewee and 83 (29%) had one other candidate at their successful interview. The mean application ratio for each post was 1.9 and the median number of candidates was one, mean 1.6 and maximum candidates seven. About half of the posts were filled by trainees from their regional training rotation. Prospective data collection on advertised posts, interviews held, expected retirements/new posts, combined with a route for trainees approaching CCT to highlight their availability may streamline recruitment and allow a more rapid recognition of recruitment problems.

Abstract
INTRODUCTION OMFS Specialty Training in the UK is usually 5 years and 'starts' at Specialty Training Year 3 (ST3). In 2007 a pilot of 'run-through' training started with Core Training (CT) posts linked to specialty training (ST1 posts). ST1 posts are usually 12 months but may be up to 24 months. METHOD UK OMFS consultants joining the OMFS specialist list between 2002 and 2019 were contacted regarding their training. If their training was extended beyond the expected date of completion, they were asked to give a primary and secondary reason from a simplified list. Results were analysed with Winstat©. RESULTS A total of 382 consultants were contacted, 325 responding (86%) and of these 290 were appointed at ST3 and their mean extension of training time was 0.63 years. For those 35 who were appointed to ST1, their training was on average 0.77 years longer than planned. Undertaking a Fellowship (33%) was the commonest reason for extension, followed by administrative delay (24%), unsuccessful attempts at the FRCS exam (12%) and training reasons (10%). Female trainees (n=37) spent on average 1.28 years longer than planned in training compared to male trainees (288 - 0.67 years). Gender differences were also present in the main reasons for extension with 12% of female respondents giving family reasons as the main cause, whereas only 2% of males gave this reason. Problems with training was the main cause for extension for 19% of females compared to 8% of males. CONCLUSIONS Understanding factors which extend training and the length of these extensions could have the twin benefits of openness for new trainees and directing support to existing trainees. Differential attainment and Equality Diversity & Inclusion (EDI) are domains whose monitoring is required by the General Medical Council and undertaken by training authorities. The small numbers of trainees in OMFS programmes may not always allow training variance to be recognised.

Abstract
BACKGROUND Previous research has shown poor hospital experiences and dire outcomes for people with intellectual disability. The main objective of this study was to prospectively track episodes for adults with intellectual disability (ID) in Australian hospitals, with a focus on indications of the quality of care provided. METHODS A prospective audit of hospital records over 35 months yielded quantitative data about patient characteristics, frequency and length of hospital episodes, diagnostic assessments and outcomes, post-emergency department (ED) destinations and post-discharge recommendations. Fifty participants were recruited largely by identification on hospital ED entry. An audit of patients' hospital records was conducted towards the end of hospital episodes, using a tool developed for the study. RESULTS Participants were mostly men (70%), aged 42.9 years on average, living mostly with family (46%) or in supported accommodation (44%). Of 157 recorded episodes, 96% started in ED, 85% required urgent or semi-urgent care and 62% were in the first 3 months of study participation. Average time in ED exceeded the 4-h national benchmark, met in 40% of episodes. One or more diagnostic assessments were conducted in 91% episodes and others in short stay units. Almost half (49%) resulted in a ward stay. With an extreme data point removed, <1-35 days were spent in wards. The most frequent diagnosis in 75% of episodes was for digestive problems, followed by nervous system problems then injuries. Median length of bed stays reflected data available for Australian refined diagnosis-related groups. High hospital re-presentations were found: for 67% of episodes in total, 26% (n = 12) of which were within 72 h and 59% (n = 23) within 30 days. CONCLUSIONS Adults with ID presented frequently to ED and often had lengthy stays. We found no indication of poor care practices in terms of hospital staff willingness to keep patients in ED and conduct of diagnostic assessments. Frequent re-presentations, however, indicated failed hospital care at some level.

Abstract
The nuclear factor I (NFI) family of transcription factors play an important role in normal development of multiple organs. Three NFI family members are highly expressed in the brain, and deletions or sequence variants in two of these, NFIA and NFIX, have been associated with intellectual disability (ID) and brain malformations. NFIB, however, has not previously been implicated in human disease. Here, we present a cohort of 18 individuals with mild ID and behavioral issues who are haploinsufficient for NFIB. Ten individuals harbored overlapping microdeletions of the chromosomal 9p23-p22.2 region, ranging in size from 225 kb to 4.3 Mb. Five additional subjects had point sequence variations creating a premature termination codon, and three subjects harbored single-nucleotide variations resulting in an inactive protein as determined using an in vitro reporter assay. All individuals presented with additional variable neurodevelopmental phenotypes, including muscular hypotonia, motor and speech delay, attention deficit disorder, autism spectrum disorder, and behavioral abnormalities. While structural brain anomalies, including dysgenesis of corpus callosum, were variable, individuals most frequently presented with macrocephaly. To determine whether macrocephaly could be a functional consequence of NFIB disruption, we analyzed a cortex-specific Nfib conditional knockout mouse model, which is postnatally viable. Utilizing magnetic resonance imaging and histology, we demonstrate that Nfib conditional knockout mice have enlargement of the cerebral cortex but preservation of overall brain structure and interhemispheric connectivity. Based on our findings, we propose that haploinsufficiency of NFIB causes ID with macrocephaly.

Abstract
SummaryFibrin formation and fibrinolysis were estimated in 89 breast cancer patients by measurement in plasma of Fibrin Fragment Bβ 15-42 and Fibrinopeptide A (FPA), serum Fibrin(ogen) Degradation Products (FDPs) and plasminogen activator by Fibrin Plate Lysis Assay. Results were compared with (a) 26 patients with benign breast diseases; and (b) 45 healthy factory workers. FPA, FDP and Bβ 15-42 Levels were elevated in both breast cancer patients and benign disease patients, but there were no significant differences between these two groups. Cancer stage, patient age and smoking habits did not affect these results, but Oestrogen Receptor (ER) positive patients had higher Bβ 15-42 values than ER negative patients (p = 0.017). These results show that fibrin formation is enhanced preoperatively in patients with either benign or malignant breast disease. The fibrinolytic response to activated coagulation may be relatively deficient in breast cancer. The roles of malignancy, stress and other factors in the causation of these abnormalities require further assessment.

Abstract
Highly conserved TREX-mediated mRNA export is emerging as a key pathway in neuronal development and differentiation. TREX subunit variants cause neurodevelopmental disorders (NDDs) by interfering with mRNA export from the cell nucleus to the cytoplasm. Previously we implicated four missense variants in the X-linked THOC2 gene in intellectual disability (ID). We now report an additional six affected individuals from five unrelated families with two de novo and three maternally inherited pathogenic or likely pathogenic variants in THOC2 extending the genotypic and phenotypic spectrum. These comprise three rare missense THOC2 variants that affect evolutionarily conserved amino acid residues and reduce protein stability and two with canonical splice-site THOC2 variants that result in C-terminally truncated THOC2 proteins. We present detailed clinical assessment and functional studies on a de novo variant in a female with an epileptic encephalopathy and discuss an additional four families with rare variants in THOC2 with supportive evidence for pathogenicity. Severe neurocognitive features, including movement and seizure disorders, were observed in this cohort. Taken together our data show that even subtle alterations to the canonical molecular pathways such as mRNA export, otherwise essential for cellular life, can be compatible with life, but lead to NDDs in humans.

Abstract
Controlled burns are commonly used to suppress woody plant regrowth and to remove accumulated unpalatable pasture from rangelands and occasionally to alter pasture composition in native pastures in central Queensland, Australia. Outcomes can be somewhat unpredictable and short-term, and reliable evidence is needed to confirm the likely long-term efficacy of such fires. We imposed a regime of repeated spring burns on native Aristida/Bothriochloa pastures growing in two contrasting eucalypt woodlands of central Queensland to determine the effects on pasture composition, ground cover, landscape stability and woody plant recruitment, all in the absence of grazing. The sites selected were a silver-leaved ironbark (Eucalyptus melanophloia F.Muell.) woodland and a poplar box (E. populnea F.Muell.) woodland.
Weather conditions precluded spring burns in 3 years out of 7 at the silver-leaved ironbark site and in 2 years out of 8 at the poplar box site. The burn intensity was variable, and frequent fires produced a marked change in abundance of only a few pasture species. Depending on the site, fires significantly increased the frequency of Enneapogon spp., Bothriochloa bladhii (Retz.) S.T.Blake and Dichanthium sericeum (R.Br.) A.Camus and reduced the frequency of some minor components such as Cymbopogon spp., Panicum effusum R.Br., Cenchrus ciliaris L. and, ephemerally, that of some forbs. Contrary to expectation, only Aristida calycina R.Br. declined in abundance among the many Aristida species present, and the abundance of Heteropogon contortus (L.) P.Beauv. ex Roem. & Schult. barely increased under regular spring fires. The total germinable seeds of herbaceous species in the soil each spring was significantly reduced by burning in the previous spring.
Repeated spring fires rarely reinforced any initial change induced by burning, and slightly lowered average ground cover as well as various indices of landscape stability and ecosystem functionality. Changes produced were not always consistent across the two communities. Though prescribed burning is often important for maintaining grazing productivity and landscape values, very regular use is not recommended.

Abstract
Degradation of proteins by the ubiquitin-proteasome system (UPS) is an essential biological process in the development of eukaryotic organisms. Dysregulation of this mechanism leads to numerous human neurodegenerative or neurodevelopmental disorders. Through a multi-center collaboration, we identified six de novo genomic deletions and four de novo point mutations involving PSMD12, encoding the non-ATPase subunit PSMD12 (aka RPN5) of the 19S regulator of 26S proteasome complex, in unrelated individuals with intellectual disability, congenital malformations, ophthalmologic anomalies, feeding difficulties, deafness, and subtle dysmorphic facial features. We observed reduced PSMD12 levels and an accumulation of ubiquitinated proteins without any impairment of proteasome catalytic activity. Our PSMD12 loss-of-function zebrafish CRISPR/Cas9 model exhibited microcephaly, decreased convolution of the renal tubules, and abnormal craniofacial morphology. Our data support the biological importance of PSMD12 as a scaffolding subunit in proteasome function during development and neurogenesis in particular; they enable the definition of a neurodevelopmental disorder due to PSMD12 variants, expanding the phenotypic spectrum of UPS-dependent disorders.

Abstract
CONTEXT Heterozygous mutations in the aggrecan gene (ACAN) cause autosomal dominant short stature with accelerated skeletal maturation. OBJECTIVE We sought to characterize the phenotypic spectrum and response to growth-promoting therapies. PATIENTS AND METHODS One hundred three individuals (57 females, 46 males) from 20 families with autosomal dominant short stature and heterozygous ACAN mutations were identified and confirmed using whole-exome sequencing, targeted next-generation sequencing, and/or Sanger sequencing. Clinical information was collected from the medical records. RESULTS Identified ACAN variants showed perfect cosegregation with phenotype. Adult individuals had mildly disproportionate short stature [median height, -2.8 standard deviation score (SDS); range, -5.9 to -0.9] and a history of early growth cessation. The condition was frequently associated with early-onset osteoarthritis (12 families) and intervertebral disc disease (9 families). No apparent genotype-phenotype correlation was found between the type of ACAN mutation and the presence of joint complaints. Childhood height was less affected (median height, -2.0 SDS; range, -4.2 to -0.6). Most children with ACAN mutations had advanced bone age (bone age - chronologic age; median, +1.3 years; range, +0.0 to +3.7 years). Nineteen individuals had received growth hormone therapy with some evidence of increased growth velocity. CONCLUSIONS Heterozygous ACAN mutations result in a phenotypic spectrum ranging from mild and proportionate short stature to a mild skeletal dysplasia with disproportionate short stature and brachydactyly. Many affected individuals developed early-onset osteoarthritis and degenerative disc disease, suggesting dysfunction of the articular cartilage and intervertebral disc cartilage. Additional studies are needed to determine the optimal treatment strategy for these patients.
