An integrated clinical approach to children at genetic risk for neurodevelopmental and psychiatric conditions: interdisciplinary collaboration and research infrastructure. J Neurodev Disord 2024; 16:37. [PMID: 38970057 PMCID: PMC11229023 DOI: 10.1186/s11689-024-09552-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2023] [Accepted: 06/04/2024] [Indexed: 07/07/2024] Open
Abstract
BACKGROUND A sizeable proportion of pathogenic genetic variants identified in young children tested for congenital differences are associated with neurodevelopmental psychiatric disorders (NPD). In this growing group, a genetic diagnosis often precedes the emergence of diagnosable developmental concerns. Here, we describe DAGSY (Developmental Assessment of Genetically Susceptible Youth), a novel interdisciplinary 'genetic-diagnosis-first' clinic integrating psychiatric, psychological and genetic expertise, and report our first observations and feedback from families and referring clinicians. METHODS We retrieved data on referral sources and indications, genetic and NPD diagnoses and recommendations for children seen at DAGSY between 2018 and 2022. Through a survey, we obtained feedback from twenty families and eleven referring clinicians. RESULTS 159 children (mean age 10.2 years, 57.2% males) completed an interdisciplinary (psychiatry, psychology, genetic counselling) DAGSY assessment during this period. Of these, 69.8% had a pathogenic microdeletion or microduplication, 21.5% a sequence-level variant, 4.4% a chromosomal disorder, and 4.4% a variant of unknown significance with emerging evidence of pathogenicity. One in four children did not have a prior NPD diagnosis, and referral to DAGSY was motivated by their genetic vulnerability alone. Following assessment, 76.7% received at least one new NPD diagnosis, most frequently intellectual disability (24.5%), anxiety (20.7%), autism spectrum (18.9%) and specific learning (16.4%) disorder. Both families and clinicians responding to our survey expressed satisfaction, but also highlighted some areas for potential improvement. CONCLUSIONS DAGSY addresses an unmet clinical need for children identified with genetic variants that confer increased vulnerability for NPD and provides a crucial platform for research in this area. DAGSY can serve as a model for interdisciplinary clinics integrating child psychiatry, psychology and genetics, addressing both clinical and research needs for this emerging population.

Chromosome 22q11.2 Deletion Syndrome: A Comprehensive Review of Molecular Genetics in the Context of Multidisciplinary Clinical Approach. Int J Mol Sci 2023; 24:ijms24098317. [PMID: 37176024 PMCID: PMC10179617 DOI: 10.3390/ijms24098317] [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: 04/14/2023] [Revised: 04/30/2023] [Accepted: 05/03/2023] [Indexed: 05/15/2023] Open
Abstract
The 22q11.2 deletion syndrome is a multisystemic disorder characterized by a marked variability of phenotypic features, making the diagnosis challenging for clinicians. The wide spectrum of clinical manifestations includes congenital heart defects-most frequently conotruncal cardiac anomalies-thymic hypoplasia and predominating cellular immune deficiency, laryngeal developmental defects, midline anomalies with cleft palate and velar insufficiency, structural airway defects, facial dysmorphism, parathyroid and thyroid gland hormonal dysfunctions, speech delay, developmental delay, and neurocognitive and psychiatric disorders. Significant progress has been made in understanding the complex molecular genetic etiology of 22q11.2 deletion syndrome underpinning the heterogeneity of clinical manifestations. The deletion is caused by chromosomal rearrangements in meiosis and is mediated by non-allelic homologous recombination events between low copy repeats or segmental duplications in the 22q11.2 region. A range of genetic modifiers and environmental factors, as well as the impact of hemizygosity on the remaining allele, contribute to the intricate genotype-phenotype relationships. This comprehensive review has been aimed at highlighting the molecular genetic background of 22q11.2 deletion syndrome in correlation with a clinical multidisciplinary approach.

O'Donoghue E, McAllister M, Rizzo R. The experiences of families receiving a diagnosis of 22q11.2 deletion syndrome in Ireland. J Genet Couns 2022. [PMID: 36575949 DOI: 10.1002/jgc4.1667] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2022] [Revised: 12/01/2022] [Accepted: 12/06/2022] [Indexed: 12/29/2022]
Abstract
Families in Ireland often wait over 1 year to see a genetic counselor (GC). This qualitative study aimed to explore the views of families who received a diagnosis of 22q11DS in Ireland regarding the need for timely access to genetic counseling at the point of diagnosis. Twenty participants were recruited through the '22q Ireland' support group, giving a response rate of approximately 10% of the total support group members. Semi-structured interviews were conducted online and by telephone which explored experiences of receiving diagnoses, medical care, genetic counseling, mental health, and coping with the diagnosis. Interviews were transcribed verbatim and analyzed using thematic analysis. The experiences of 20 participants were classified into five main themes: Receiving Diagnosis, Interactions with Healthcare Professionals (HCPs, excluding GCs), Medical Care, Information, and Impact of Condition. Participants reported receiving diagnoses for their children in a sub-optimal manner due to inappropriate settings and insufficient information, support, and pre-test counseling. Parents reported feeling responsible for managing their child's complex and fragmented medical care. Participants reported insufficient empathy and little awareness of 22q11DS among HCPs. Participants perceived genetic counseling to be associated with family planning and reported delayed, if any, access to services. Mental health was a particular worry among participants. Conferences about 22q11DS are the main source of information for parents. Participants reported a range of emotions after diagnosis and described the family impact. The findings suggest both an association between HCPs' poor understanding of 22q11DS and the perceived lack of empathy from HCPs and fragmented medical care. There is an identified need for advocacy of the GC profession in Ireland to support these families. Increased awareness of 22q11DS among HCPs and the development of a coordinated care pathway for 22q11DS, with timely access to genetic counseling, may improve care and lead to better outcomes.

Abstract
Background 22q11.2 Deletion Syndrome (22q11.2DS) can result in array of congenital abnormalities including immune dysfunction. International guidelines recommend immune evaluation of 22q11.2DS patients prior to live vaccine administration. A rotavirus vaccination program for infants aged 2 and 4 months was implemented in British Columbia (BC) in 2012. Adherence to immune workup recommendations prior to 2 months of age in patients with 22q11.2DS and adverse events following immunization is not known. Methods A retrospective chart review of children diagnosed with 22q11.2DS in BC from January 1, 2012 to January 1, 2019 was conducted. Demographic, clinical, laboratory, immunization data and adverse reactions to vaccines were obtained. International guidelines were used as a reference for adherence to immunologic workup recommendations. Results Forty-two children with 22q11.2DS were included. Immunization records were available for 39 children, and 22 (52.3%) received at least one dose of a live rotavirus vaccine. No adverse events following immunization were noted in clinical records. While 25 out of 27 (92.6%) of patients who received an immunological workup had a CD4 + lymphocyte count to qualify for safe administration of a live vaccination, only 12 (44%) received the Rotavirus vaccine. Of 22 infants diagnosed with 22q11.DS prior to 8 weeks of age, only ten (45.5%) received an immune workup before the rotavirus vaccine. Conclusions The majority of our infant cohort did not receive medical care consistent with international 22q11.2DS vaccination and immunological surveillance recommendations. More effective dissemination of 22q11.2DS guidelines and improved immunological assessment for infants with 22q11.2DS in BC is necessary.

Abstract
BACKGROUND Pediatric inflammatory bowel disease (IBD) carries significant morbidity and requires extensive medical and often surgical intervention. The aim of this study was to evaluate the impact of a dedicated Multidisciplinary clinic on the outcomes of children with IBD. METHODS A retrospective review of a prospective database, established to track quality and outcomes of children undergoing an abdominal operation for IBD, was performed. Children who were managed before (09/2017-03/2019) and after (04/2019-06/2020) establishment of the multidisciplinary clinic were examined. The clinic instituted several care process protocols including early recovery (ERAS) and garnered additional resources for patients (wound ostomy, nutrition, social work, etc.) Primary outcomes were unanticipated return to the operating room, length of stay, ER visits within 30 days of surgery and hospital readmissions within 30 days of surgery. RESULTS We identified 41 children who underwent a total of 80 major abdominal operations; 46.3% of procedures occurred before and 53.7% occurred after instituting our clinic. There were no notable changes in disease distribution (e.g., ulcerative colitis vs. Crohn's), disease severity, medication exposure, or case urgency (elective vs. emergent). ER visits within 30 days of surgery decreased (4 (9.3%) vs. 10 (27%), p = 0.04) as did readmissions within 30 days of surgery (1 (2.3%) vs. 9 (24.3%), p = 0.005). CONCLUSIONS Implementation of a dedicated multidisciplinary clinic for IBD and its attendant focus on protocols and appropriate use of adjunctive resources was associated with decreased emergency department visits and hospital readmissions in the post-operative setting.

Abstract
OBJECTIVE To identify cumulative 5-year healthcare costs and healthcare days in children with anorectal malformation (ARM) and to compare the cumulative 5-year healthcare costs and healthcare days in children with ARM with 3 control cohorts: healthy, premature, and congenital heart disease (CHD). STUDY DESIGN We performed a retrospective case-control study using the Truven MarketScan database of commercial claims encounters between 2008 and 2017. The ARM, CHD, and premature cohorts were identified using a targeted list of International Classification of Diseases 9th or 10th Revision diagnosis and Current Procedural Terminology codes. The healthy cohort included patients without ARM, preterm birth, or CHD. RESULTS We identified 664 children with ARM, 3356 children with heart disease, 63 190 children who were born preterm, and 2947 healthy patients. At 5 years, the total healthcare costs of children with ARM ($273K, 95% CI $168K-$378K) were similar to the premature cohort ($246K, 95% CI $237K-$255K) and lower than the CHD cohort ($466K, 95% CI $401K-$530K, P < .001). Total healthcare days were similar in children with ARM (158 days, 95% CI 117-198) and prematurity (141 days, 95% CI 137-144) but lower than CHD (223 days, 95% CI 197-250, P = .02). In ARM, outpatient care (126 days, 95% CI 93-159) represented the largest contribution to total healthcare days. CONCLUSIONS Children with ARM accumulate similar healthcare costs to children with prematurity and comparable healthcare days to children with CHD and prematurity in the first 5 years of life. Outpatient care represents the majority of healthcare days in children with ARM, identifying this as a target for quality improvement and demonstrating the long-term impact of this condition.
