The dataset provided lacks any empirical evidence to effectively summarize the role of ARID1B haploinsufficiency in human disease. Without specific case-level genetic evidence, including patient mutations and functional studies, it is not possible to offer a synthesized critique or overview of the gene's implications in the disease phenotype. Therefore, conclusive remarks on clinical features associated with ARID1B haploinsufficiency, individual patient cases, and functional study outcomes cannot be reported. Further research and data compilation are required to assess the role of ARID1B and substantiate its contribution to disease etiology.

The dataset provides evidence of the pathogenic role of ARID1B haploinsufficiency in human disease, supported by a description of a male patient presenting with developmental delay, speech impairment, mild dysmorphic features, and borderline intellectual disability. The identified mutation in this patient is a de novo balanced translocation, t(5;6)(q11;q25.3), leading to disruption of ARID1B at the breakpoint, with potential null or loss-of-function consequences, as confirmed by parental testing. This mutation exemplifies the case-level evidence suggesting that haploinsufficiency of ARID1B is a significant factor in the clinical phenotype of individuals affected by the associated disease. Furthermore, the synthesis of this case with a review of literature and clinical observations substantiates the association of ARID1B haploinsufficiency with a spectrum of disorders including intellectual disabilities, corpus callosum abnormalities, Coffin-Siris syndrome, and autism. These functional studies collectively contribute to our understanding of the critical role ARID1B plays in neurodevelopment and associated pathologies.

This dataset presents evidence for the haploinsufficiency of the ARID1B gene in patients with neurodevelopmental disorders. Four key cases include a 'translocation patient' with a chromosome 6 breakpoint truncating ARID1B, 'Patient 1' with a de novo balanced reciprocal translocation, 'Patient 2' with a 0.2-Mb intragenic deletion, and 'patients 3 and 4' with deletions confined to ARID1B. Each case manifests intellectual disability, severe speech impairment, and varying dysmorphic features. Inheritance was tested for the translocation patient and Patient 1, establishing de novo occurrence of the mutations. Clinical features of ARID1B-associated haploinsufficiency frequently involved corpus callosum abnormalities, intellectual disability, autism spectrum disorder, hypotonia, and feeding problems in infancy. Supporting these clinical correlations, functional studies including Quantitative polymerase chain reaction (Q-PCR) confirmed the gene-disease association with differential expression of ARID1B highlighting the functional impact of haploinsufficiency on neurodevelopmental phenotypes.

This study profiles ARID1B haploinsufficiency in six patients presenting with a spectrum of clinical features such as intellectual disability, distinct facial dysmorphism, plantar fat pads, and speech impairments. Heterozygous deletions, including a ~1.2 Mb deletion at 6q25.3 (encompassing ARID1B), and frameshift as well as nonsense mutations like NM_020732.3(ARID1B):c.3208_3209delAA and NM_020732.3(ARID1B):c.2941C>T were identified across patients, often originating de novo. Inheritance was tested and confirmed de novo status in five instances; however, inheritance information was not available for the initial patient discussed. Functional analyses supported haploinsufficiency as a significant disease mechanism, demonstrating reduced cell cycle re-entry in patient-derived fibroblasts upon serum starvation, significantly reduced ARID1B transcription levels, and perturbed cell cycle regulation. Collectively, these results underscore the critical role of ARID1B function in neurodevelopmental disorders and affirm the genetic evidence for ARID1B haploinsufficiency in pathogenesis.

Haploinsufficiency of ARID1B, a Member of the SWI/SNF-A Chromatin-Remodeling Complex, Is a Frequent Cause of Intellectual Disability

Our findings indicate that haploinsufficiency of ARID1B, a member of the SWI/SNF-A chromatin-remodeling complex, is a common cause of ID, and they add to the growing evidence that chromatin-remodeling defects are an important contributor to neurodevelopmental disorders.

This dataset provides case-level evidence of haploinsufficiency in the ARID1B gene across nine patients exhibiting a spectrum of clinical phenotypes including severe developmental delay, intellectual disability, and muscular hypotonia. Each patient carried a heterozygous mutation predicted or proven to lead to loss of function, such as deletions, duplications creating null alleles, and nonsense or frameshift mutations. Mutations noted include a 2.5 Mb deletion, duplication of exons 5 and 6, and nonsense mutations like c.3919C>T and c.4038T>A. Frameshift mutations recorded include c.6463_6473del and c.1114dupC among others. Inheritance tests confirmed all these mutations occurred de novo. The clinical features strongly associated with ARID1B haploinsufficiency are consistent across cases, particularly intellectual disability and developmental delays. Functional studies including transcript analysis via RT-PCR supported the hypothesis that variants such as c.4110G>A induce exon skipping, leading to frameshifts and premature stop codons, confirming their role in disease phenotypes. Additionally, clinical observations underscore that the symptoms overlap between patients with point mutations and those with large genomic deletions, further validating ARID1B haploinsufficiency as the causal factor in the observed clinical manifestations.

Haploinsufficiency of ARID1B, a Member of the SWI/SNF-A Chromatin-Remodeling Complex, Is a Frequent Cause of Intellectual Disability

Our findings indicate that haploinsufficiency of ARID1B, a member of the SWI/SNF-A chromatin-remodeling complex, is a common cause of ID, and they add to the growing evidence that chromatin-remodeling defects are an important contributor to neurodevelopmental disorders.

Significant contribution of intragenic deletions to ARID1B mutation spectrum

To the Editor:The arrival of high-throughput sequencing technology has revolutionized the field of medical genetics by steeply increasing the number of identified disease-causing variants, often bringing the previously unknown genes to the center of genetic investigations. The perfect example of this shift is the ARID1B gene, which in just several years became known as one of the most commonly mutated genes in Coffin–Siris syndrome as well as in isolated intellectual disability (ID).
