Modeling Williams syndrome from a neurodevelopmental perspective: recent advances, model-based translational insights and future directions.
Williams syndrome (WS; OMIM #194,050) is a multisystem pediatric genetic disorder caused by a heterozygous microdeletion of a 1.5-1.8 Mb region at chromosome 7q11.23, encompassing 26 to 28 genes. Clinical hallmarks include cardiovascular anomalies, distinctive craniofacial morphology and neurodevelopmental deficits characterized by hypersociability, cognitive impairment and anxiety. Although causative therapies for WS still remain elusive, advances in gene editing and forebrain organoids have already greatly furthered our understanding of the underlying mechanisms. This narrative review was conducted by searching for papers using PubMed/MEDLINE. Relevant publications were identified using single and/or combined keywords including: Williams syndrome, 7q11.23, microdeletion, microduplication, atypical deletion, neurodevelopment, neuroanatomy, neuroimaging. cognitive impairment, mouse models, GTF2I, GTF2IRD1, CLIP2, LIMK1, NCF1, EIF4H, STX1A/B, FZD9, HIP1, CLDN3, FKBP6, organoid, induced pluripotent stem cell (iPSC) and forebrain organoids. Mouse models including multigene deletion strains recapitulating the WS critical region and single-gene knockout strains targeting Gtf2i, Gtf2ird1, Clip2 and Limk1 replicate key WS neurodevelopmental phenotypes, substantially contributing to mechanistic studies and therapeutic screening. In addition, forebrain organoids derived from patients or generated by gene editing have provided human-specific insights into progenitor dynamics, synaptic function, and ribosome biogenesis. This review synthesizes recent progress in WS modeling in the context of neurodevelopmental impairments. While animal models and forebrain organoids have substantially accelerated both mechanistic understanding and translational research in WS, effective diagnostic and therapeutic approaches are still unavailable. Integration of animal models and forebrain organoids, together with the advanced technologies, will be essential for biomarker discovery and development of mechanism-based therapeutic approaches.
Unaltered empathy-related behaviors in Williams-Beuren syndrome mouse models.
Williams-Beuren Syndrome (WBS), a neurodevelopmental disorder caused by a heterozygous microdeletion at chromosome 7q11.23, is characterized by hypersociability and enhanced affective empathy. However, the specific genetic and neural mechanisms within the WBS locus underlying this elevated empathic response remain unknown. Here, we investigated empathy-related behaviors, including observational fear and allogrooming, in WBS mouse models harboring a deletion within the conserved syntenic region on mouse chromosome 5. We demonstrate that WBS mice exhibited emotional contagion and prosocial consolation behaviors comparable to their wild-type controls. Furthermore, WBS mice with single-gene deletions of the cortex-enriched genes Abhd11, Limk1, Mlxipl, and Stx1a also showed unaffected empathic freezing behavior. Collectively, our findings suggest that the enhanced empathic responsiveness reported in individuals with WBS may be influenced by reduced social inhibition toward others, while acknowledging that limitations of current rodent behavioral assays preclude definitive conclusions regarding primary neural mechanisms of empathy.
Clinical features and management of 16q24.3 microdeletion KBG syndrome: literature review.
KBG syndrome (KBGS) is an autosomal dominant disorder presenting with diverse clinical features. Although multiple cases of the microdeletion subtype have been reported, discussions regarding its phenotypic characteristics remain relatively limited. This study aims to summarize the clinical features and management strategies for pediatric KBGS patients caused by 16q24.3 microdeletions, thereby enhancing awareness of this rare disease. We conducted a retrospective analysis of the clinical manifestations, genetic characteristics, and clinical management of four pediatric patients with microdeletion-type KBGS at our institution, and systematically reviewed relevant literature to compile clinical data on affected patients. All four patients exhibited typical facial features (such as cupid's bow lip, protruding ears, and thick eyebrows), skeletal abnormalities, and ocular anomalies. Whole-exome sequencing revealed a 16q24.3 microdeletion encompassing the ANKRD11 gene. A literature review identified 68 cases (including the present cases) of KBG syndrome caused by 16q24.3 microdeletions, with a male-to-female ratio of 38:21 (9 cases of unknown sex), including 6 Chinese patients. Non-Chinese patients typically exhibit distinctive facial features including a prominent nasal root (14/28, 50%) and prominent forehead (15/33, 45.45%), whereas Chinese patients display characteristic facial features such as a cupid's bow lip, protruding ears, and thick eyebrows. Among the East Asian population (represented by Chinese individuals), the incidence of prominent eyebrows, cupid's bow lip, and delayed bone age was higher than in other populations. Patients with microdeletions involving only ANKRD11 exhibited a higher prevalence of the characteristic triangular facial appearance and intellectual disability. In this study, the two children received recombinant human growth hormone therapy, achieving catch-up growth with height increases of 1.66 standard deviations and 0.68 standard deviations, respectively. The clinical phenotype of patients with microdeletion-type KBGS mainly includes characteristic facial features, macrodontia, skeletal deformities, neurological abnormalities, and eye deformities. Cupid's bow lip, protruding ears, and thick eyebrows may be characteristic facial features of Chinese children with KBGS. Genetic testing is required for definitive diagnosis. Treatment primarily relies on multidisciplinary teams providing symptomatic supportive care, with the aim of achieving early diagnosis and treatment to improve patient outcomes.
Clinical and genetic characterization of patients with Digeorge syndrome: a single-center, first report from Sudan.
DiGeorge syndrome (DGS; OMIM #188400), also known as 22q11.2 deletion syndrome, is characterized by cardiac defects, abnormal facial features, thymic hypoplasia, cleft palate, and hypocalcemia. The syndrome is ranked as the second most common chromosomal change after Down’s syndrome, accounting for 1 in 2000 newborns. DGS syndrome is typically diagnosed through CGH and/or FISH analysis in developed countries. However, in low-resource healthcare settings, diagnosis often relies primarily on clinical manifestations due to limited access to genetic testing. The present study, the first of its kind, seeks to deepen the understanding of both the clinical and genetic aspects of DGS among Sudanese patients by employing FISH analysis as a confirmatory test. Between 2020 and 2023, 19 patients with DGS as a provisional diagnosis were referred to the Elite Center for Genetic Services for genetic testing and counseling. Cytogenetics and chromosomal analysis were performed following standard protocols, complemented by chromosomal FISH analysis using locus-specific TUPLE1 and α-satellite DNA probes. Of the 19 patients, 9 (47.4%) were male, and 10 (52.6%) were female, with ages ranging from 2 months to 3 years, and a mean of 11 ± 8.6 months. The most common presentations were CHD in 13 (68.4%), dysmorphic features in 12 (63.2%), and recurrent respiratory tract infections in 9 (47.4%). The least common presenting complaint was intellectual disability in only 2 (10.5%) patients. The echocardiogram revealed isolated heart defects in 9 (47.4%) patients, and only 4 (21.1%) had combined cardiac anomalies. Laboratory tests showed hypocalcemia in all four neonatal patients (21.1%) with a previous history of neonatal convulsions. Conventional cytogenetic analyses were suggestive but non-conclusive {46,XY,?del(22) and 46,XX,?del(22)} for DGS. The complementary FISH analysis confirmed the diagnosis by detecting the microdeletion in the DGCR of chromosome 22. Our study highlights the late presentation of DGS for genetic diagnoses. This may be due to limited access to genetic testing, late referrals from treating physicians, or the high cost of the tests. A key area for future research is the environmental factors, such as skin bleaching, that may contribute to DGS in Sudan and other African populations.
Early rebalancing of neuroinflammatory cascades lastingly rescues prefrontal deficits in a 22q11.2ds model.
Cognitive deficits, a characteristic feature of neuropsychiatric disorders, reflect perturbed activity in neuronal networks. Increasing evidence has linked neuroinflammation to impaired neuronal activity and resulting cognitive dysfunction, yet the underlying cellular mechanisms and developmental dynamics remain largely unclear. Here, we address this knowledge gap by investigating the Df(16)A mouse model of human 22q11.2 microdeletions, a prevalent chromosomal abnormality associated with an increased incidence of neuropsychiatric disorders. During early postnatal development, Df(16)A+/- mice show an imbalance of inflammatory signaling markers accompanied by increased microglial density in the superficial layers of the prefrontal cortex. Consequently, spine densities of pyramidal neurons were decreased, resulting in disrupted patterns of prefrontal neuronal activity during development and poor performance in a set-shifting task at juvenile age. Early treatment with minocycline, an anti-inflammatory drug, lastingly rescued these deficits in Df(16)A+/- mice, rebalancing signaling cascades and restoring neural activity as well as cognitive performance. These findings identify the early rebalancing of inflammatory signaling cascades as a promising therapeutic strategy for mitigating pathophysiological trajectories associated with the 22q11.2 deletion syndrome.
