    Purpose: ARID1B is one of the most frequently mutated genes in intellectual disability cohorts. Thus, far few adult-aged patients with ARID1B-related disorder have been described, which limits our understanding of the disease's natural history and our ability to counsel patients and their families. Methods: Data on patients aged 18+ years with ARID1B-related disorder were collected through an online questionnaire completed by clinicians and parents. Results: Eighty-seven adult patients with ARID1B were included. Cognitive functioning ranged from borderline to severe intellectual disability. Patients identified through the genetic workup of their child were either mosaic or had a variant in exon 1. New clinical features identified in this population are loss of skill (16/64, 25%) and recurrent patella luxation (12/45, 32%). Self-sustainability data showed that 88% (45/51) could eat independently, and 16% (7/45) could travel alone by public transport. Facial photo analysis showed that patients' photographs taken at different ages clustered consistently, separate from matched controls. Conclusion: The ARID1B spectrum is broad, and as patients age, there is a significant shift in the medical aspects requiring attention. To address the changing medical needs with increasing age, we have formulated recommendations to promote timely intervention in an attempt to mitigate disease progression.

    Biallelic CRELD1 variants cause a multisystem syndrome, including neurodevelopmental phenotypes, cardiac dysrhythmias, and frequent infections
    (Elsevier, 2024) Jeffries, Lauren; Mis, Emily K.; McWalter, Kirsty; Donkervoort, Sandra; Brodsky, Nina N.; Carpier, Jean-Marie; Ji, Weizhen; Ionita, Cristian; Roy, Bhaskar; Morrow, Jon S.; Darbinyan, Armine; Iyer, Krishna; Aul, Ritu B.; Banka, Siddharth; Chao, Katherine R.; Cobbold, Laura; Cohen, Stacey; Custodio, Helena M.; Drummond-Borg, Margaret; Elmslie, Frances; Finanger, Erika; Hainline, Bryan E.; Helbig, Ingo; Hewson, Stacy; Hu, Ying; Jackson, Adam; Josifova, Dragana; Konstantino, Monica; Leach, Meganne E.; Mak, Bryan; McCormick, David; McGee, Elisabeth; Nelson, Stanley; Nguyen, Joanne; Nugent, Kimberly; Ortega, Lucy; Goodkin, Howard P.; Roeder, Elizabeth; Roy, Sani; Sapp, Katie; Saade, Dimah; Sisodiya, Sanjay M.; Stals, Karen; Towner, Shelley; Wilson, William; Deciphering Developmental Disorders; Genomics England Research Consortium; Undiagnosed Disease Network; Khokha, Mustafa K.; Bönnemann, Carsten G.; Lucas, Carrie L.; Lakhani, Saquib A.; Medical and Molecular Genetics, School of Medicine
    Purpose: We sought to delineate a multisystem disorder caused by recessive cysteine-rich with epidermal growth factor-like domains 1 (CRELD1) gene variants. Methods: The impact of CRELD1 variants was characterized through an international collaboration utilizing next-generation DNA sequencing, gene knockdown, and protein overexpression in Xenopus tropicalis, and in vitro analysis of patient immune cells. Results: Biallelic variants in CRELD1 were found in 18 participants from 14 families. Affected individuals displayed an array of phenotypes involving developmental delay, early-onset epilepsy, and hypotonia, with about half demonstrating cardiac arrhythmias and some experiencing recurrent infections. Most harbored a frameshift in trans with a missense allele, with 1 recurrent variant, p.(Cys192Tyr), identified in 10 families. X tropicalis tadpoles with creld1 knockdown displayed developmental defects along with increased susceptibility to induced seizures compared with controls. Additionally, human CRELD1 harboring missense variants from affected individuals had reduced protein function, indicated by a diminished ability to induce craniofacial defects when overexpressed in X tropicalis. Finally, baseline analyses of peripheral blood mononuclear cells showed similar proportions of immune cell subtypes in patients compared with healthy donors. Conclusion: This patient cohort, combined with experimental data, provide evidence of a multisystem clinical syndrome mediated by recessive variants in CRELD1.

    BICRA, a SWI/SNF Complex Member, Is Associated with BAF-Disorder Related Phenotypes in Humans and Model Organisms
    (Elsevier, 2020-12-03) Barish, Scott; Barakat, Tahsin Stefan; Michel, Brittany C.; Mashtalir, Nazar; Phillips, Jennifer B.; Valencia, Alfredo M.; Ugur, Berrak; Wegner, Jeremy; Scott, Tiana M.; Bostwick, Brett; Murdock, David R.; Dai, Hongzheng; Perenthaler, Elena; Nikoncuk, Anita; van Slegtenhorst, Marjon; Brooks, Alice S.; Keren, Boris; Nava, Caroline; Mignot, Cyril; Douglas, Jessica; Rodan, Lance; Nowak, Catherine; Ellard, Sian; Stals, Karen; Lynch, Sally Ann; Faoucher, Marie; Lesca, Gaetan; Edery, Patrick; Engleman, Kendra L.; Zhou, Dihong; Thiffault, Isabelle; Herriges, John; Gass, Jennifer; Louie, Raymond J.; Stolerman, Elliot; Washington, Camerun; Vetrini, Francesco; Otsubo, Aiko; Pratt, Victoria M.; Conboy, Erin; Treat, Kayla; Shannon, Nora; Camacho, Jose; Wakeling, Emma; Yuan, Bo; Chen, Chun-An; Rosenfeld, Jill A.; Westerfield, Monte; Wangler, Michael; Yamamoto, Shinya; Kadoch, Cigall; Scott, Daryl A.; Bellen, Hugo J.; Medical and Molecular Genetics, School of Medicine
    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.

    De Novo ZMYND8 variants result in an autosomal dominant neurodevelopmental disorder with cardiac malformations
    (Elsevier, 2022-09) Dias, Kerith-Rae; Carlston, Colleen M.; Blok, Laura E. R.; De Hayr , Lachlan; Nawaz, Urwah; Evans, Carey-Anne; Bayrak-Toydemir, Pinar; Htun, Stephanie; Zhu, Ying; Ma, Alan; Lynch, Sally Ann; Moorwood, Catherine; Stals , Karen; Ellard, Sian; Bainbridge, Matthew N.; Friedman, Jennifer; Pappas, John G.; Rabin , Rachel; Nowak, Catherine B.; Douglas, Jessica; Wilson, Theodore E.; Guillen Sacoto, Maria J.; Mullegama, Sureni V.; Palculict , Timothy Blake; Kirk, Edwin P.; Pinner, Jason R.; Edwards, Matthew; Montanari, Francesca; Graziano, Claudio; Pippucci, Tommaso; Dingmann, Bri; Glass , Ian; Mefford , Heather C.; Shimoji , Takeyoshi; Suzuki, Toshimitsu; Yamakawa, Kazuhiro; Streff, Haley; Schaaf, Christian P.; Slavotinek, Anne M.; Voineagu , Irina; Carey, John C.; Buckley, Michael F.; Schenck, Annette; Harvey, Robert J.; Roscioli , Tony; Medical and Molecular Genetics, School of Medicine
    Purpose ZMYND8 encodes a multidomain protein that serves as a central interactive hub for coordinating critical roles in transcription regulation, chromatin remodeling, regulation of super-enhancers, DNA damage response and tumor suppression. We delineate a novel neurocognitive disorder caused by variants in the ZMYND8 gene. Methods An international collaboration, exome sequencing, molecular modeling, yeast two-hybrid assays, analysis of available transcriptomic data and a knockdown Drosophila model were used to characterize the ZMYND8 variants. Results ZMYND8 variants were identified in 11 unrelated individuals; 10 occurred de novo and one suspected de novo; 2 were truncating, 9 were missense, of which one was recurrent. The disorder is characterized by intellectual disability with variable cardiovascular, ophthalmologic and minor skeletal anomalies. Missense variants in the PWWP domain of ZMYND8 abolish the interaction with Drebrin and missense variants in the MYND domain disrupt the interaction with GATAD2A. ZMYND8 is broadly expressed across cell types in all brain regions and shows highest expression in the early stages of brain development. Neuronal knockdown of the Drosophila ZMYND8 ortholog results in decreased habituation learning, consistent with a role in cognitive function. Conclusion We present genomic and functional evidence for disruption of ZMYND8 as a novel etiology of syndromic intellectual disability.

    Demonstration of Parent Training to Address Early Self-Injury in Young Children with Intellectual and Developmental Delays
    (Springer Nature, 2018-11) Fodstad, Jill C.; Kirsch, Alexandra; Faidley, Micah; Bauer, Nerissa; Psychiatry, School of Medicine
    Individuals with intellectual and developmental disabilities (IDD) are at a high risk for engaging in self-injurious behavior (SIB). Prognosis is poor when SIB emerges early. Limited research exists on interventions teaching parents how to manage their young child's SIB. This investigation assessed the feasibility of adapting an applied behavior analytic parent training program with 11 parents of children 1-5 years of age with IDD and SIB. Quantitative and observational measures were used to assess outcomes; semi-structured interviews assessed caregiver satisfaction. Outcomes yielded preliminary data suggesting the adapted curriculum was feasible and acceptable to parents. Initial efficacy outcomes yielded decreases in SIB and observed negative parent-child interactions on pre- and post-measures. Qualitative data provided areas for further curriculum refinement.

    Long-term childhood outcomes for babies born at term who were exposed to antenatal corticosteroids
    (Elsevier, 2023) Osteen, Samantha J.; Yang, Ziyi; McKinzie, Alexandra H.; Teal, Evgenia; Tepper, Robert S.; Rhoads, Eli; Quinney, Sara K.; Haneline, Laura S.; Haas, David M.; Obstetrics and Gynecology, School of Medicine
    Background: Antenatal corticosteroids improve neonatal outcomes when administered to infants who are at risk of preterm delivery. Many women who receive antenatal corticosteroids for threatened preterm labor proceed to deliver at term. Thus, long-term outcomes should be evaluated for term-born infants who were exposed to antenatal corticosteroids in utero. Objective: This study aimed to compare long-term outcomes between term-born children aged ≥5 years who were born to women who received antenatal corticosteroids for threatened preterm labor and children whose mothers were also evaluated for threatened preterm labor but did not receive antenatal corticosteroids. Study design: We performed a retrospective cohort study of children born at ≥37 weeks' gestation, aged ≥5 years, and born to mothers diagnosed with threatened preterm labor during pregnancy. The primary exposure of interest was receiving antenatal corticosteroids. Among the collected childhood medical conditions, the primary outcome of interest was a diagnosis of asthma. Results: Of the 3556 term-born children aged ≥5 years, 629 (17.6%) were exposed to antenatal corticosteroids (all betamethasone), and 2927 (82.3%) were controls whose mothers were evaluated for threatened preterm birth but did not get antenatal corticosteroid injections. Women receiving antenatal corticosteroids had higher rates of maternal comorbidities (diabetes mellitus, hypertension; P≤.01). Antenatal corticosteroid-exposed children had no difference in diagnosis of asthma (12.6% vs 11.6%), attention deficit disorder, or developmental delay (P=.47, .54, and .10, respectively). Controlling for maternal and neonatal characteristics, asthma was not different between those exposed to antenatal corticosteroids and controls (odds ratio, 1.05; 95% confidence interval, 0.79-1.39). The odds of the child's weight percentile being <10% were increased for antenatal corticosteroid-exposed children born at term (odds ratio, 2.00; 95% confidence interval, 1.22-3.25). Conclusion: Children born at term who were exposed to antenatal corticosteroids may have increased odds of being in a lower growth percentile than those not exposed. However, rates of diagnoses such as asthma, developmental delay, and attention deficit disorders were not different.

    Mixed Methods Analysis of Caregiver Satisfaction With the Early Autism Evaluation Hub System
    (Sage, 2024-12-12) Martin, Ann Marie; Huskins, Jordan; Paxton, Angela; Nafiseh, Amira; Ciccarelli, Mary R.; Keehn, Brandon; McNally Keehn, Rebecca; Pediatrics, School of Medicine
    Community-based methods for autism evaluation may be one solution for ameliorating delays in diagnosis, which are exacerbated for children from minoritized backgrounds. However, limited research has examined caregiver satisfaction with community-based models of autism evaluation. Thus, our objective was to use a mixed-methods approach to investigate caregiver satisfaction with their child's autism evaluation conducted across a statewide system of primary care autism diagnosis. Results indicated overall high satisfaction and no significant differences were found between satisfaction total scores nor caregiver stress and any child/family demographic variables. Satisfaction and stress were also not related to autism diagnostic outcome, clinician diagnostic certainty, or diagnostic accuracy. Qualitative suggestions for evaluation improvement include more thorough explanation of diagnosis and service recommendations. Overall, our findings indicate high caregiver satisfaction with multiple dimensions of community-based autism evaluation in the primary care setting, suggesting this may be a feasible and sustainable model that caregivers find acceptable.

    Phenotypic expansion of POGZ-related intellectual disability syndrome (White-Sutton syndrome)
    (Wiley, 2020-01) Batzir, Nurit Assia; Posey, Jennifer E.; Song, Xiaofei; Akdemir, Zeynep Coban; Rosenfeld, Jill A.; Brown, Chester W.; Chen, Emily; Holtrop, Shannon G.; Mizerik, Elizabeth; Moreno, Margarita Nieto; Payne, Katelyn; Raas-Rothschild, Annick; Scott, Richard; Vernon, Hilary J.; Zadeh, Neda; Lupski, James R.; Sutton, V. Reid; Neurology, School of Medicine
    White-Sutton syndrome (WHSUS) is a recently-identified genetic disorder resulting from de novo heterozygous pathogenic variants in POGZ. Thus far, over 50 individuals have been reported worldwide, however phenotypic characterization and data regarding the natural history are still incomplete. Here we report the clinical features of 22 individuals with 21 unique loss of function POGZ variants. We observed a broad spectrum of intellectual disability and/or developmental delay with or without autism, and speech delay in all individuals. Other common problems included ocular abnormalities, hearing loss and gait abnormalities. A validated sleep disordered breathing questionnaire identified symptoms of obstructive sleep apnea in 4/12 (33%) individuals. A higher-than-expected proportion of cases also had gastrointestinal phenotypes, both functional and anatomical, as well as genitourinary anomalies. In line with previous publications, we observed an increased body mass index (BMI) z-score compared to the general population (mean 0.59, median 0.9; p 0.0253). Common facial features included microcephaly, broad forehead, midface hypoplasia, triangular mouth, broad nasal root and flat nasal bridge. Analysis of the Baylor Genetics clinical laboratory database revealed that POGZ variants were implicated in approximately 0.14% of cases who underwent clinical exome sequencing for neurological indications with or without involvement of other body systems. This study describes a greater allelic series and expands the phenotypic spectrum of this new syndromic form of intellectual disability and autism.

    Supporting Development for Children in a Family-Centered Recovery Home Setting: A Play-Based and Educational Program
    (2024-04-21) Leonard, Erin; Belkiewitz, Johnna; Department of Occupational Therapy, School of Health and Human Sciences; Young, Nikole
    Play is a child’s most important occupation. Through play, children develop fine motor and gross motor skills, social skills, and independence. Occupational therapists have a role in addressing play development and caregiver education in many settings, including family-centered residential recovery housing. Research has established that children impacted by parental substance use often experience developmental delays impacting play engagement. Barriers to age-appropriate play participation include parental lack of experience and education on developmental milestones and age-appropriate activities. The capstone student collaborated with the site to develop and implement a play-based and educational program with the purpose of encouraging developmentally appropriate play engagement for the children residing in the recovery home. The goal of this program was to target caregiver confidence and satisfaction in promoting developmentally appropriate play for their children. Results of the study indicate the staff and participants were satisfied with the implemented program and experienced improved confidence and competence in facilitating the development of their children following program implementation.
