Abstract
Rubinstein-Taybi syndrome (RTS) is an archetypical genetic syndrome that is characterised by intellectual disability, well-defined facial features, distal limb anomalies and atypical growth, among numerous other signs and symptoms. It is caused by variants in either of two genes (CREBBP, EP300) which encode for the proteins CBP and p300, which both have a function in transcription regulation and histone acetylation. As a group of international experts and national support groups dedicated to the syndrome, we realised that marked heterogeneity currently exists in clinical and molecular diagnostic approaches and care practices in various parts of the world. Here, we outline a series of recommendations that document the consensus of a group of international experts on clinical diagnostic criteria for types of RTS (RTS1: CREBBP; RTS2: EP300), molecular investigations, long-term management of various particular physical and behavioural issues and care planning. The recommendations as presented here will need to be evaluated for improvements to allow for continued optimisation of diagnostics and care.

Behavioral and neuropsychiatric challenges across the lifespan in individuals with Rubinstein-Taybi syndrome. Front Genet 2023; 14:1116919. [PMID: 37415602 PMCID: PMC10321757 DOI: 10.3389/fgene.2023.1116919] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2022] [Accepted: 06/06/2023] [Indexed: 07/08/2023] Open
Abstract
Introduction: Rubinstein-Taybi syndrome (RSTS) is a rare congenital disorder characterized by developmental and intellectual disability, broadening of thumbs and halluces, and characteristic facial features. Pathogenic variants in CREBBP lead to RSTS type 1 (RSTS1) and in EP300 lead to RSTS type 2 (RSTS2). Individuals with RSTS can demonstrate a variety of behavioral and neuropsychiatric challenges, including anxiety, hyperactivity/inattention, self-injury, repetitive behaviors, and aggression. Behavioral challenges are consistently reported as one of the primary factors impacting quality of life. Despite the high prevalence and morbidity of behavioral and neuropsychiatric features of RSTS, a paucity of data exists regarding its natural history. Methods: To better understand the neurocognitive and behavioral challenges faced by individuals with RSTS, 71 caregivers of individuals with RSTS, ranging in age from one to 61 years, completed four questionnaires measuring obsessive compulsive disorder (OCD)-like symptoms, anxiety, challenging behaviors, and adaptive behavior and living skills. Results: Results revealed a high prevalence of neuropsychiatric and behavioral challenges across ages. We found specific challenging behaviors were worse in school age individuals. Scaled adaptive behavior and living skill scores differed across ages with an increased gap between typically developing peers becoming more apparent at older ages. Between types, individuals with RSTS2 had better adaptive behavior and living skills and less stereotypic behaviors but higher social phobia than individuals with RSTS1. Further, female individuals with RSTS1 appear to have increased hyperactivity. However, both groups had impairments in adaptive functioning compared to typically developing peers. Discussion: Our findings support and expand previous reports of a high prevalence of neuropsychiatric and behavioral challenges in individuals with RSTS. However, we are the first to report differences between types of RSTS. Further, age-related differences were seen with higher challenging behaviors within school-age individuals, which may improve over time, and lower adaptive behavioral skills compared to normative scales. Anticipation of these potential differential challenges across age is vital for proactive management for individuals with RSTS. Our study underscores the importance of enacting neuropsychiatric and behavioral screening earlier in childhood so appropriate management can be implemented. However, further longitudinal studies in larger cohorts are needed to understand better how behavioral and neuropsychiatric characteristics of RSTS evolve over the lifespan and differentially affect subpopulation groups.

The developmental trajectories of the behavioral phenotype and neuropsychiatric functioning in Cornelia de Lange and Rubinstein Taybi syndromes: A longitudinal study. Am J Med Genet A 2023; 191:424-436. [PMID: 36373849 PMCID: PMC10099472 DOI: 10.1002/ajmg.a.63039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2022] [Revised: 10/14/2022] [Accepted: 10/21/2022] [Indexed: 11/16/2022]
Abstract
Several changes in the behavioral phenotype arise with the growth of children affected by Cornelia de Lange Syndrome (CdLS) and Rubinstein-Taybi Syndrome (RSTS). However, previous research relied on a cross-sectional study design turning into age-related comparisons of different syndromic cohorts to explore age-dependent changes. We aim to outline the variating pathways of the neuropsychiatric functioning across the lifespan in CdLS and RSTS, through the setting up of a longitudinal study design. The sample included 14 patients with CdLS and 15 with RSTS. The assessments were carried out in two different timepoints. Our findings highlight that the cognitive profile of CdLS is subjected to a worsening trend with decreasing Intellectual Quotient (IQ) scores from T0 to T1, whereas RSTS shows a stable IQ over time. Patients affected by RSTS show greater improvements compared to CdLS in communication, daily living skills, social abilities, and motor skills across the lifespan. Both syndromes report an upward trend in behavioral and emotional difficulties even if CdLS exhibit a significant and major deterioration compared to individuals with RSTS. Being aware of the early dysfunctional patterns which might pave the way for later neuropsychiatric impairments is the first step for planning preventive interventions.

Abstract
This exploratory cross-sectional study aimed to examine the family quality of life (FQoL) among 51 Brazilian families who have children with Rubinstein-Taybi syndrome, a rare genetic disorder. Data were collected using sociodemographic and clinical data forms, as well as the Beach Center FQoL Scale, a 5-point Likert scale ranging from "very dissatisfied" (1) to "very satisfied" (5). The average score of the overall FQoL was 3.93 ± 0.64. Families' scores were higher for family interaction (4.17 ± 0.76), parenting (4.13 ± 0.61), and disability-related support (4.08 ± 0.76) domains, and lower for the family's emotional well-being (3.31 ± 0.96) and physical/material well-being (3.76 ± 0.82) domains. Family income, attendance at religious services, presence of ocular abnormalities, and aggressive behavior explained 46.2% of the variance in the overall FQoL. In summary, FQoL seems to be anchored in aspects such as family interaction and the care of parents, and be negatively affected by emotional issues, physical, and material limitations. In this context, psychological assistance should be provided to both parents and siblings whenever indicated, for improving emotional well-being and increasing family resilience. Additionally, investments in social policies, services, and human and material resources are needed to improve the physical and material conditions of families, promote better health care, and therefore reduce the family burden.

Abstract
Environmental factors and life experiences impinge on brain circuits triggering adaptive changes. Epigenetic regulators contribute to this neuroadaptation by enhancing or suppressing specific gene programs. The paralogous transcriptional coactivators and lysine acetyltransferases CREB binding protein (CBP) and p300 are involved in brain plasticity and stimulus-dependent transcription, but their specific roles in neuroadaptation are not fully understood. Here we investigated the impact of eliminating either CBP or p300 in excitatory neurons of the adult forebrain of mice from both sexes using inducible and cell type-restricted knock-out strains. The elimination of CBP, but not p300, reduced the expression and chromatin acetylation of plasticity genes, dampened activity-driven transcription, and caused memory deficits. The defects became more prominent in elderly mice and in paradigms that involved enduring changes in transcription, such as kindling and environmental enrichment, in which CBP loss interfered with the establishment of activity-induced transcriptional and epigenetic changes in response to stimulus or experience. These findings further strengthen the link between CBP deficiency in excitatory neurons and etiopathology in the nervous system.SIGNIFICANCE STATEMENT How environmental conditions and life experiences impinge on mature brain circuits to elicit adaptive responses that favor the survival of the organism remains an outstanding question in neurosciences. Epigenetic regulators are thought to contribute to neuroadaptation by initiating or enhancing adaptive gene programs. In this article, we examined the role of CREB binding protein (CBP) and p300, two paralogous transcriptional coactivators and histone acetyltransferases involved in cognitive processes and intellectual disability, in neuroadaptation in adult hippocampal circuits. Our experiments demonstrate that CBP, but not its paralog p300, plays a highly specific role in the epigenetic regulation of neuronal plasticity gene programs in response to stimulus and provide unprecedented insight into the molecular mechanisms underlying neuroadaptation.

Abstract
Rubinstein-Taybi syndrome (RTS) is a rare genetic syndrome associated with growth delay, phenotypic facial characteristics, microcephaly, developmental delay, broad thumbs, and big toes. Most research on RTS has focused on the genotype and physical phenotype; however, several studies have described behavioral, cognitive, social, and emotional characteristics, elucidating the behavioral phenotype of RTS. The reporting of this review was informed by PRISMA guidelines. A systematic search of CINAHL, Medline, and PsychINFO was carried out in March 2021 to identify group studies describing behavioral, cognitive, emotional, psychiatric, and social characteristics in RTS. The studies were quality appraised. Characteristics reported include repetitive behavior, behaviors that challenge, intellectual disability, mental health difficulties, autism characteristics, and heightened sociability. Findings were largely consistent across studies, indicating that many characteristics are likely to form part of the behavioral phenotype of RTS. However, methodological limitations, such as a lack of appropriate comparison groups and inconsistency in measurement weaken these conclusions. There is a need for multi-disciplinary studies, combining genetic and psychological measurement expertise within single research studies. Recommendations are made for future research studies in RTS.

Abstract
BACKGROUND AND AIM There is mounting evidence highlighting that Cornelia de Lange Syndrome (CdLS) and Rubinstein-Taybi Syndrome's (RSTS) behavioral phenotypes are not stable over individual developmental trajectories and that several psychiatric disorders might arise with age. Our study aims to examine the specific hallmarks of psychopathology and behavioral phenotypes in four different age ranges: infancy and toddlerhood, early childhood, middle childhood, and adolescence, in both genetic syndromes. METHOD The sample included 44 patients with CdLS (48% boys, age = 6.67 ± 4.36) and 31 with RSTS (48% boys, age = 6.89 ± 4.58) recruited through follow-ups. Cognitive, behavioral, and autism assessments were carried out with Griffith's scales or the Leiter-R, the Child Behavior Checklist, and the Child Autism Rating Scales 2. Multiple ANOVA 2 × 4 were run to outline behavioral phenotypic age-related syndromic markers and ANCOVA to value the weight of IQ and ASD-related traits on the psychopathological outcome. RESULTS Findings showed that anxiety is a crucial phenotypic hallmark, independent of IQ but associated with autistic traits, that increases from infancy to adolescence in both CdLS and RSTS. CONCLUSION AND IMPLICATIONS Being aware of the developmental challenges that growing children are called to face is essential for drawing up proper standards of assessment turning into target age-related interventions, ensuring these patients personalized healthcare and improvement in life quality.

Abstract
The existing knowledge about morbidity in adults with Rubinstein-Taybi syndrome (RTS) is limited and detailed data on their natural history and response to management are needed for optimal care in later life. We formed an international, multidisciplinary working group that developed an accessible questionnaire including key issues about adults with RTS and disseminated this to all known RTS support groups via social media. We report the observations from a cohort of 87 adult individuals of whom 43 had a molecularly confirmed diagnosis. The adult natural history of RTS is defined by prevalent behavioural/psychiatric problems (83%), gastrointestinal problems (73%) that are represented mainly by constipation; and sleep problems (62%) that manifest in a consistent pattern of sleep apnoea, difficulty staying asleep and an increased need for sleep. Furthermore, over than half of the RTS individuals (65%) had skin and adnexa-related problems. Half of the individuals receive multidisciplinary follow-up and required surgery at least once, and most frequently more than once, during adulthood. Our data confirm that adults with RTS enjoy both social and occupational possibilities, show a variegated experience of everyday life but experience a significant morbidity and ongoing medical issues which do not appear to be as coordinated and multidisciplinary managed as in paediatric patients. We highlight the need for optimal care in a multidisciplinary setting including the pivotal role of specialists for adult care.

Abstract
BACKGROUND Cornelia de Lange (CdLS), Fragile X (FXS) and Rubinstein-Taybi syndromes (RTS) evidence unique profiles of autistic characteristics. To delineate these profiles further, the development of early social cognitive abilities in children with CdLS, FXS and RTS was compared to that observed in typically developing (TD) and autistic (AUT) children. METHODS Children with CdLS (N = 22), FXS (N = 19) and RTS (N = 18), completed the Early Social Cognition Scale (ESCogS). Extant data from AUT (N = 19) and TD (N = 86) children were used for comparison. RESULTS Similar to AUT children, children with CdLS, FXS and RTS showed an overall delay in passing ESCogS tasks. Children with CdLS showed a similar degree of delay to AUT children and greater delay than children with FXS and RTS. The CdLS, FXS and RTS groups did not pass tasks in the same sequence observed in TD and AUT children. Children with CdLS (p = 0.04), FXS (p = 0.02) and RTS (p = 0.04) performed better on tasks requiring understanding simple intentions in others significantly more than tasks requiring joint attention skills. CONCLUSIONS An underlying mechanism other than general cognitive delay may be disrupting early social cognitive development in children with CdLS, FXS and RTS. Factors that may disrupt early social cognitive development within these syndromes are discussed.

Abstract
Background Rubinstein–Taybi syndrome (RSTS) is a rare congenital malformation syndrome with clinical characteristics such as hypertrichosis, high arched eyebrows, large beaked nose, and broad thumbs and halluces. RSTS patients showed intellectual disability and health problems such as short stature, ophthalmologic abnormalities, congenital heart defects, genitourinary defects, and variable types of tumors. Although mutations in CREBBP and EP300 genes are associated with RSTS features, genetic causation is still unknown in 30% of patients. Methods We present clinical and molecular genetic characteristics of 25 unrelated Korean patients clinically diagnosed with RSTS. Sanger sequencing analysis and multiplex ligation‐dependent probe amplification for CREBBP in 25 patients and exome sequencing of CREBBP‐negative cases were performed in nine patients successively. Results Causative variants were identified in 20 (80%) patients: 16 (64%) in CREBBP and 4 (16%) in EP300. All the identified variants predict protein truncation (11 frameshift, 2 nonsense, 1 splicing‐site, and 6 large intragenic deletions); there are no repeatedly identified sequence variants. Four of the CREBBP and all four EP300 variants are novel. Intellectual disability was noted in 24/25 patients (96%); no difference was found between CREBBP and EP300 groups. One patient with a CREBBP variant (4%) had malignant tumor. Conclusions To date, this is the largest cohort of patients with RSTS including EP300‐related patients in Korea. Future large‐scale studies to find genetic mutation of molecularly unsolved patients and long‐term prospective studies are required to validate our results.

Abstract
Rubinstein-Taybi syndrome (RTS) is a rare genetic disorder. Family-centered care (FCC) is a healthcare delivery approach that aims to create an equal partnership between caregivers and providers. FCC has been shown to improve parental wellbeing, their knowledge of the condition and care, and improve their feelings of self-efficacy and personal control. The purpose of this study was to explore the healthcare experiences of family caregivers of children and adults with RTS to understand the issues they encounter when working with medical professionals and to examine their perspectives on how to improve FCC. Primary family caregivers of individuals with RTS took an online mixed-method survey that contained three primary components: a demographic survey, the Measures of Processes of Care-20 (MPOC-20) [a measure of the FCC an individual feels they receive], and a qualitative assessment of negative and positive interactions with medical professionals and priority areas for improvement. Qualitative data were analyzed using thematic analysis. Quantitative data were analyzed with descriptive statistics. An analysis of variance test was used to determine whether values statistically differed between different-age groups of individuals with RTS being cared for. Sixty-three caregivers completed the survey. The average score of the Providing General Information subscale of the MPOC-20 was 3.18, lower than that seen in other studies. The average scores of the other subscales of the MPOC-20 ranged from 4.60 to 5.02, comparable to other studies of caregivers of children with other medical conditions. All aspects of FCC were ranked as important by caregivers. There were no differences in MPOC-20 values between those caring for the individuals with RTS in different-age groups reviewed. In the qualitative responses, parents noted that experiences with medical professionals would be improved if healthcare providers actively provided FCC, collaborated with parents and other providers, respected caregivers' time and breadth of knowledge and lived experience, gave a more balanced description of the condition, showed greater respect toward their loved ones and included them in the conversation, and made an effort to learn about RTS. The changes that parents would like to see in their child's care were not specific to one discipline and could be implemented by all healthcare specialists. While caregivers report that they receive moderate levels of FCC, they indicated that areas of FCC could be improved.

Abstract
The Rubinstein-Taybi syndrome (RSTS) is a rare congenital developmental disorder characterized by a typical facial dysmorphism, distal limb abnormalities, intellectual disability, and many additional phenotypical features. It occurs at between 1/100,000 and 1/125,000 births. Two genes are currently known to cause RSTS, CREBBP and EP300, mutated in around 55% and 8% of clinically diagnosed cases, respectively. To date, 500 pathogenic variants have been reported for the CREBBP gene and 118 for EP300. These two genes encode paralogs acting as lysine acetyltransferase involved in transcriptional regulation and chromatin remodeling with a key role in neuronal plasticity and cognition. Because of the clinical heterogeneity of this syndrome ranging from the typical clinical diagnosis to features overlapping with other Mendelian disorders of the epigenetic machinery, phenotype/genotype correlations remain difficult to establish. In this context, the deciphering of the patho-physiological process underlying these diseases and the definition of a specific episignature will likely improve the diagnostic efficiency but also open novel therapeutic perspectives. This review summarizes the current clinical and molecular knowledge and highlights the epigenetic regulation of RSTS as a model of chromatinopathy.

Abstract
BACKGROUND Rubinstein-Taybi syndrome (RSTS; OMIM 180849) is a rare autosomal dominant developmental disorder with an estimated prevalence of one case per 125,000 live births. RSTS is characterized by typical face, broad thumbs and halluces, short stature, and intellectual disability. Facial dysmorphy is characteristic with microcephaly, low frontal hairline, arched eyebrows, long eyelashes, convex profile of nose, narrow palate, and micrognathia. RSTS is mainly due to mutations or microdeletions of the CREBBP gene (about 60%) and more rarely of the EP300 gene (8%). OBJECTIVE Clinical description and identification of mutations of patients with Rubinstein Taybi syndrome. METHODS PCR and direct sequencing of CREBBP gene. RESULTS We report here, the clinical and molecular data of a series of six Moroccan patients with a phenotype of RSTS. The molecular study of the major gene CREBBP (by Sanger Sequencing followed by CGH array, if sequence normal) revealed point mutations in five patients. For the sixth patient, CGH array revealed a microdeletion carrying the CREBBP gene. Through this work, we emphasize the importance of clinical expertise in the diagnosis, management and genetic counseling in Rubinstein Taybi syndrome.

Abstract
We directly assessed the broader aspects of sociability (social enjoyment, social motivation, social interaction skills and social discomfort) in individuals with Cornelia de Lange (CdLS), fragile X (FXS) and Rubinstein-Taybi syndromes (RTS), and their association with autism characteristics and chronological age in these groups. Individuals with FXS (p < 0.01) and RTS (p < 0.01) showed poorer quality of eye contact compared to individuals with CdLS. Individuals with FXS showed less person and more object attention than individuals with CdLS (p < 0.01). Associations between sociability and autism characteristics and chronological age differed between groups, which may indicate divergence in the development and aetiology of different components of sociability across these groups. Findings indicate that individuals with CdLS, FXS and RTS show unique profiles of sociability.

Abstract
Rubinstein-Taybi syndrome (RSTS, OMIM*180849) is a rare autosomal dominant disorder, characterized by distinctive facial features, short stature, broad and often angulated thumbs and halluces, with occasional congenital anomalies. Characteristic facial dysmorphic features include downslanting palpebral fissures, low hanging columella. RSTS is caused by pathogenic variants in two ubiquitously expressed and highly homologous genes, CREBBP (OMIM*600140) and EP300 (OMIM*600140). Clinical features were well reported especially in Caucasian ethnicity. We would like to report the clinical phenotype of RSTS in our Chinese population and highlight four novel mutations in CREBBP gene.

Abstract
The journey to receiving a diagnosis for rare genetic disease can be long and emotionally impactful. This study describes parental experiences of receiving their child's diagnosis of Rubinstein-Taybi syndrome (RTS), a rare genetic condition characterized by growth and developmental delay together with dysmorphic features. Parents from the RTS Australia support group participated in qualitative, semi-structured phone interviews, which were transcribed verbatim and thematically analyzed. Questions focused on psychosocial challenges and benefits pre and post-diagnosis. Ten mothers and three fathers participated, with the mean age of diagnosis being 8 months. Parents reported positive psychological effects from a slight delay in diagnosis, and negative effects from an extended diagnostic delay, suggesting the ideal time for a parent to receive a diagnosis lies in the post attachment stage, prior to the development of significant parental concerns. This stage would vary depending on condition severity. Parents desired a diagnosis to reduce uncertainty; however, uncertainty remained post diagnosis, and shifted its focus from broadly encompassing etiology and prognosis, to specifically focusing on concerns regarding severity within the spectrum. Perceived benefits of a diagnosis mainly centered on the provision of a label. Parents articulated that a label increased social acceptance, enhanced coping, promoted communication, and improved access to medical, financial, and support services. This study provides insights into the experience of families prior to and following receipt of a diagnosis. It also highlights the possibility of an optimal time window to receive a diagnosis; in which bonding is maximized and parental distress is minimized.

Abstract
Although recurrent infections in Rubinstein-Taybi syndrome (RSTS) are common, and probably multifactorial, immunological abnormalities have not been extensively described with only isolated cases or small case series of immune deficiency and dysregulation having been reported. The objective of this study was to investigate primary immunodeficiency (PID) and immune dysregulation in an international cohort of patients with RSTS. All published cases of RSTS were identified. The corresponding authors and researchers involved in the diagnosis of inborn errors of immunity or genetic syndromes were contacted to obtain up-to-date clinical and immunological information. Ninety-seven RSTS patients were identified. For 45 patients, we retrieved data from the published reports while for 52 patients, a clinical update was provided. Recurrent or severe infections, autoimmune/autoinflammatory complications, and lymphoproliferation were observed in 72.1%, 12.3%, and 8.2% of patients. Syndromic immunodeficiency was diagnosed in 46.4% of individuals. Despite the broad heterogeneity of immunodeficiency disorders, antibody defects were observed in 11.3% of subjects. In particular, these patients presented hypogammaglobulinemia associated with low B cell counts and reduction of switched memory B cell numbers. Immunoglobulin replacement therapy, antibiotic prophylaxis, and immunosuppressive treatment were employed in 16.4%, 8.2%, and 9.8% of patients, respectively. Manifestations of immune dysfunctions, affecting mostly B cells, are more common than previously recognized in patients with RSTS. Full immunological assessment is warranted in these patients, who may require detailed investigation and specific supportive treatment. Graphical Abstract.

Abstract
Unique socio-behavioural phenotypes are reported for individuals with different neurodevelopmental disorders. Here, the effects of adult familiarity and nature of interaction on social anxiety and social motivation were investigated in individuals with fragile X (FXS; n = 20), Cornelia de Lange (CdLS; n = 20) and Rubinstein-Taybi (RTS; n = 20) syndromes, compared to individuals with Down syndrome (DS; n = 20). The Social Anxiety and Motivation Rating Scale was employed whilst participants completed four social tasks, each administered separately by a familiar adult, and also by an unfamiliar adult. Compared to participants with DS, those with FXS and RTS exhibited high levels of social anxiety but similar levels of social motivation. Participants with CdLS showed heightened social anxiety and reduced social motivation only during interactions with an unfamiliar adult when active participation was voluntary.

Am J Med Genet A 2018; 176:597-608. [PMID: 29359884 PMCID: PMC5838508 DOI: 10.1002/ajmg.a.38603] [Citation(s) in RCA: 32] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2017] [Revised: 12/11/2017] [Accepted: 12/20/2017] [Indexed: 11/10/2022]
Abstract
Rubinstein–Taybi syndrome (RSTS) is a multiple congenital anomalies syndrome associated with mutations in CREBBP (70%) and EP300 (5–10%). Previous reports have suggested an increased incidence of specific benign and possibly also malignant tumors. We identified all known individuals diagnosed with RSTS in the Netherlands until 2015 (n = 87) and studied the incidence and character of neoplastic tumors in relation to their CREBBP/EP300 alterations. The population–based Dutch RSTS data are compared to similar data of the Dutch general population and to an overview of case reports and series of all RSTS individuals with tumors reported in the literature to date. Using the Nationwide Network and Registry of Histopathology and Cytopathology in the Netherlands (PALGA Foundation), 35 benign and malignant tumors were observed in 26/87 individuals. Meningiomas and pilomatricomas were the most frequent benign tumors and their incidence was significantly elevated in comparison to the general Dutch population. Five malignant tumors were observed in four persons with RSTS (medulloblastoma; diffuse large‐cell B‐cell lymphoma; breast cancer; non‐small cell lung carcinoma; colon carcinoma). No clear genotype–phenotype correlation became evident. The Dutch population‐based data and reported case studies underscore the increased incidence of meningiomas and pilomatricomas in individuals with RSTS. There is no supporting evidence for an increased risk for malignant tumors in individuals with RSTS, however, due to the small numbers this risk may not be fully dismissed.

Abstract
Anxiety disorders are heightened in specific genetic syndromes in comparison to intellectual disability of heterogeneous aetiology. In this study, we described and contrasted anxiety symptomatology in fragile X (FXS), Cornelia de Lange (CdLS) and Rubinstein-Taybi syndromes (RTS), and compared the symptomatology to normative data for typically-developing children and children diagnosed with an anxiety disorder. Scores did not differ between children diagnosed with an anxiety disorder and (a) participants with FXS on social phobia, panic/agoraphobia, physical injury fears, and obsessive-compulsive subscales (b) participants with CdLS on separation anxiety, generalized anxiety, panic/agoraphobia, physical injury fears and obsessive-compulsive subscales, and (c) participants with RTS on panic/agoraphobia and obsessive-compulsive subscales. The results highlight divergent profiles of anxiety symptomatology between these groups.

Abstract
Syndromic monogenic obesity typically follows Mendelian patterns of inheritance and involves the co-presentation of other characteristics, such as mental retardation, dysmorphic features and organ-specific abnormalities. Previous reviews on obesity have reported 20 to 30 syndromes but no systematic review has yet been conducted on syndromic obesity. We searched seven databases using terms such as 'obesity', 'syndrome' and 'gene' to conduct a systematic review of literature on syndromic obesity. Our literature search identified 13,719 references. After abstract and full-text review, 119 relevant papers were eligible, and 42 papers were identified through additional searches. Our analysis of these 161 papers found that 79 obesity syndromes have been reported in literature. Of the 79 syndromes, 19 have been fully genetically elucidated, 11 have been partially elucidated, 27 have been mapped to a chromosomal region and for the remaining 22, neither the gene(s) nor the chromosomal location(s) have yet been identified. Interestingly, 54.4% of the syndromes have not been assigned a name, whereas 13.9% have more than one name. We report on organizational inconsistencies (e.g. naming discrepancies and syndrome classification) and provide suggestions for improvements. Overall, this review illustrates the need for increased clinical and genetic research on syndromes with obesity.

Abstract
The Social Security Administration (SSA) Compassionate Allowances List (CAL) was created in 2008, generating a mechanism within SSA for identifying diseases and other medical conditions that by definition meet social security's standards for disability benefits. Currently, over 200 conditions are included in this expedited review program, though few of them are neurodevelopmental in nature. Exploration of a novel method for inclusion of additional conditions on CAL was undertaken using one condition as an exemplar. Peer-reviewed literature available in academic databases was reviewed and used as empirical evidence to demonstrate whether Rubinstein-Taybi syndrome (RTS) invariably met the three disability criteria set forth by SSA. After in-depth exploration of the empirical literature, RTS was found to meet SSA's definition, suggesting this condition should receive consideration as an addition to the Compassionate Allowances Initiative.

Abstract
ObjectifDécrire un tableau d’autisme associé au syndrome de Rubinstein–Taybi à travers le cas d’un enfant suivi à la consultation du service de pédopsychiatrie, hôpital Razi.MéthodologieIl s’agit d’un garçon de 6 ans, qui a été adressé par son médecin généticien en mai 2014 pour prise en charge d’une irritabilité et troubles de comportement. L’enfant avait des antécédents de persistance de canal artériel opéré à l’âge de 8 mois. Le développement était marqué par un retard des acquisitions psychomotrices. L’inquiétude de la mère a commencé vers l’âge de 18 mois où elle avait constaté des anomalies phénotypiques chez son fils avec apparition des stéréotypies gestuelles, angoisse inexpliquée, troubles des interactions sociales et troubles de la communication non verbale devenus manifestes à l’âge de 4 ans. Il a été adressé en neuropédiatrie pour explorations (EEG de veille/sommeil, IRM cérébrale : normaux) puis a été adressé à la consultation de génétique ou le diagnostic de syndrome de de Rubinstein–Taybi a été suspecté puis confirmé. L’examen a trouvé un enfant avec un retard staturo-pondéral important (–4 à–3 DS), des dysmorphies qui seront comparées aux données de la littérature. Le contact était très difficile, voire absent, il était très agité et refusait tout contact. L’interrogatoire de la mère et l’utilisation de la CARS nous ont permis de poser le diagnostic de trouble de spectre de l’autisme. L’indication de le mettre sous neuroleptiques était discutable vus ses antécédents cardiaques. L’évolution était marquée par une amélioration des interactions sociales, des troubles de la communication non verbale et des troubles de comportement associé.ConclusionNous discuterons les caractéristiques sémiologiques autistiques de cet enfant en comparaison aux données de la littérature de même que les facteurs génétiques et développementaux et environnementaux dans leurs rôles étiopathogéniques.

Abstract
Rubinstein-Taybi syndrome (RSTS) is a rare, congenital, plurimalformative, and neurodevelopmental disorder. Clinical diagnosis can be complicated by the heterogeneous clinical presentation and the lack of a consensus list of diagnostic criteria, and it is confirmed by molecular tests in approximately 55 to 78% of cases. The etiology is partially known with mutations in two functionally related genes: CREBBP and EP300. Notwithstanding the knowledge on clinical, genetic, and allelic heterogeneity, no clear genotype-phenotype correlation has yet been established. Standardized guidelines for the management of pediatric patients are available and therapy for RSTS patients is currently only symptomatic. In this article, several clinic and genetic aspects of RSTS are critically reviewed.

Abstract
Background Rubinstein-Taybi syndrome (RSTS) is an extremely rare autosomal dominant genetic disease, with an estimated prevalence of one case per 125,000 live births. RSTS is characterized by typical facial features, microcephaly, broad thumbs and first toes, intellectual disability, and postnatal growth retardation. However, no standard diagnostic criteria are available for RSTS. In this review, we summarized the clinical features and genetic basis of RSTS and highlighted areas for future studies on an appropriate diagnostic protocol and follow-up care for RSTS. Discussion RSTS is primarily characterized by delayed growth in height and weight, microcephaly, dysmorphic facial features, and broad thumbs and big toe. Over 90% RSTS individuals with disabilities survive to adulthood, but healthcare for these patients is particularly complex, time-consuming, and costly. In addition, no standard diagnostic criteria and follow-up care guidelines are available for RSTS. It has been shown that mutations in the genes encoding the cyclic-AMP-regulated enhancer binding protein (CREBBP) and the E1A-binding protein p300 (EP300) contributed to the development of RSTS. Therefore, genetic tests are useful for the diagnosis of RSTS, although most RSTS cases are currently diagnosed based on clinical features. Summary The clinical features of RSTS have been extensively studied, which significantly contributes to the diagnosis of this extremely rare syndrome. However, the pathogenesis and genotype-phenotype associations of RSTS are largely unknown. Therefore, multicenter studies and international cooperation are highlighted for better understanding of this disease, establishing standard diagnostic criteria, and providing professional management and follow-up care of RSTS.

Abstract
BACKGROUND Rubinstein-Taybi syndrome (RSTS) is a multiple congenital anomalies-intellectual disability syndrome. One of the complications is keloid formation. Keloids are proliferative fibrous growths resulting from excessive tissue response to skin trauma. OBJECTIVES To describe the clinical characteristics of keloids in individuals with RSTS reported in the literature and in a cohort of personally evaluated individuals with RSTS. PATIENTS AND METHODS We performed a literature search for descriptions of RSTS individuals with keloids. All known individuals with RSTS in the Netherlands filled out three dedicated questionnaires. All individuals with (possible) keloids were personally evaluated. A further series of individuals with RSTS from the U.K. was personally evaluated. RESULTS Reliable data were available for 62 of the 83 Dutch individuals with RSTS and showed 15 individuals with RSTS (24%) to have keloids. The 15 Dutch and 12 U.K. individuals with RSTS with keloids demonstrated that most patients have multiple keloids (n > 1: 82%; n > 5: 30%). Mean age of onset is 11·9 years. The majority of keloids are located on the shoulders and chest. The mean length × width of the largest keloid was 7·1 × 2·8 cm, and the mean thickness was 0·7 cm. All affected individuals complained of itching. Generally, treatment results were disappointing. CONCLUSIONS Keloids occur in 24% of individuals with RSTS, either spontaneously or after a minor trauma, usually starting in early puberty. Management schedules have disappointing results. RSTS is a Mendelian disorder with a known molecular basis, and offers excellent opportunities to study the pathogenesis of keloids in general and to search for possible treatments.

Abstract
When embryological development of the internal and/or external genitalia is disrupted, the patient presents with a disorder of sex development (DSD) in the neonatal period or sometime later in life. Some of these patients have other, nongenital malformations, which makes their overall management more complex than if they just had a DSD. This Review summarises these malformation syndromes and discusses the recent research into their aetiology. The genetic causes of these malformation syndromes, when they are known, will also be described. Many specific genetic mutations are now known in malformation syndromes with a defect in hormonal function. By contrast, the genetic causes remain unknown in many nonhormonal morphological anomalies that affect the genitalia.

Abstract
Several genetic disorders are characterized by normal head size at birth, followed by deceleration in head growth resulting in postnatal microcephaly. Among these are classic disorders such as Angelman syndrome and MECP2-related disorder (formerly Rett syndrome), as well as more recently described clinical entities associated with mutations in CASK, CDKL5, CREBBP, and EP300 (Rubinstein-Taybi syndrome), FOXG1, SLC9A6 (Christianson syndrome), and TCF4 (Pitt-Hopkins syndrome). These disorders can be identified clinically by phenotyping across multiple neurodevelopmental and neurobehavioral realms, and enough data are available to recognize these postnatal microcephaly disorders as separate diagnostic entities in their own right. A second diagnostic grouping, comprised of Warburg MICRO syndrome, Cockayne syndrome, and Cerebral-oculo-facial skeletal syndrome, share similar features of somatic growth failure, ophthalmologic, and dysmorphologic features. Many postnatal microcephaly syndromes are caused by mutations in genes important in the regulation of gene expression in the developing forebrain and hindbrain, although important synaptic structural genes also play a role. This is an emerging group of disorders with a fascinating combination of brain malformations, specific epilepsies, movement disorders, and other complex neurobehavioral abnormalities.

Abstract
OBJECT Rubinstein-Taybi syndrome (RSTS) is a rare condition with characteristic genetic and clinical features. The presence of variable vertebral and neural axis abnormalities has been reported in the literature. We describe the possible association of multiple different spinal anomalies in these patients. RESULTS The radiological exams of two RSTS patients (a female and male of 11 and 13 years) have been reviewed. Both patients presented the simultaneous association of craniovertebral junction bony abnormalities (occipito-C1 condyle subluxation and posterior C2-C3 arches fusion), Chiari I malformation, spinal cord syrinx, low-lying conus medullaris, and scoliosis. CONCLUSION An association of different spinal cord anomalies is possible in RSTS patients and has to be investigated with a comprehensive neuroimaging study in order to address the proper treatment and prevent the development of neurologic deficits.

Abstract
Keloid disease is a fibroproliferative dermal tumor with an unknown etiology that occurs after a skin injury in genetically susceptible individuals. Increased familial aggregation, a higher prevalence in certain races, parallelism in identical twins, and alteration in gene expression all favor a remarkable genetic contribution to keloid pathology. It seems that the environment triggers the disease in genetically susceptible individuals. Several genes have been implicated in the etiology of keloid disease, but no single gene mutation has thus far been found to be responsible. Therefore, a combination of methods such as association, gene-gene interaction, epigenetics, linkage, gene expression, and protein analysis should be applied to determine keloid etiology.
