Phenotypic expansion and variable expressivity in individuals with JARID2-related intellectual disability: A case series. Clin Genet 2022; 102:136-141. [PMID: 35533077 DOI: 10.1111/cge.14149] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2022] [Revised: 04/20/2022] [Accepted: 05/05/2022] [Indexed: 11/30/2022]
Abstract
Loss of function variants in JARID2 were recently reported in 16 patients with a neurodevelopmental disorder characterized by delays, intellectual and learning disability, autism, behavioral abnormalities, and dysmorphic features. Most cases were de novo, with only one variant inherited from an affected parent. Here, we present 7 additional individuals from 5 families with pathogenic or likely pathogenic JARID2 variants, confirming this gene-disease association and highlighting palatal abnormalities and heart defect as part of the phenotype. In addition, we report inheritance of JARID2 variants from mildly affected parents, demonstrating the variable expressivity of the disease. We also note the high prevalence of intragenic JARID2 copy number variants, emphasizing the importance of exon-level analysis.

JARID2 haploinsufficiency is associated with a clinically distinct neurodevelopmental syndrome. Genet Med 2020; 23:374-383. [PMID: 33077894 DOI: 10.1038/s41436-020-00992-z] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2020] [Revised: 09/15/2020] [Accepted: 09/23/2020] [Indexed: 11/08/2022] Open
Abstract
PURPOSE JARID2, located on chromosome 6p22.3, is a regulator of histone methyltransferase complexes that is expressed in human neurons. So far, 13 individuals sharing clinical features including intellectual disability (ID) were reported with de novo heterozygous deletions in 6p22-p24 encompassing the full length JARID2 gene (OMIM 601594). However, all published individuals to date have a deletion of at least one other adjoining gene, making it difficult to determine if JARID2 is the critical gene responsible for the shared features. We aim to confirm JARID2 as a human disease gene and further elucidate the associated clinical phenotype. METHODS Chromosome microarray analysis, exome sequencing, and an online matching platform (GeneMatcher) were used to identify individuals with single-nucleotide variants or deletions involving JARID2. RESULTS We report 16 individuals in 15 families with a deletion or single-nucleotide variant in JARID2. Several of these variants are likely to result in haploinsufficiency due to nonsense-mediated messenger RNA (mRNA) decay. All individuals have developmental delay and/or ID and share some overlapping clinical characteristics such as facial features with those who have larger deletions involving JARID2. CONCLUSION We report that JARID2 haploinsufficiency leads to a clinically distinct neurodevelopmental syndrome, thus establishing gene-disease validity for the purpose of diagnostic reporting.

Possible effect of SNAIL family transcriptional repressor 1 polymorphisms in non-syndromic cleft lip with or without cleft palate. Clin Oral Investig 2018; 22:2535-2541.

Abstract
OBJECTIVE Orofacial development is a complex process subjected to failure impairing. Indeed, the cleft of the lip and/or of the palate is among the most frequent inborn malformations. The JARID2 gene has been suggested to be involved in non-syndromic cleft lip with or without cleft palate (nsCL/P) etiology. JARID2 interacts with the polycomb repressive complex 2 (PRC2) in regulating the expression patterns of developmental genes by modifying the chromatin state. MATERIALS AND METHODS Genes coding for the PRC2 components, as well as other genes active in cell differentiation and embryonic development, were selected for a family-based association study to verify their involvement in nsCL/P. A total of 632 families from Italy and Asia participated to the study. RESULTS Evidence of allelic association was found with polymorphisms of SNAI1; in particular, the rs16995010-G allele was undertransmitted to the nsCL/P cases [P = 0.004, odds ratio = 0.69 (95% C.I. 0.54-0.89)]. However, the adjusted significance value corrected for all the performed tests was P = 0.051. CONCLUSIONS The findings emerging by the present study suggest for the first time an involvement of SNAI1 in the nsCL/P onset. CLINICAL RELEVANCE Interestingly, SNAI1 is known to promote epithelial to mesenchymal transition by repressing E-cadherin expression, but it needs an intact PRC2 to act this function. Alterations of this process could contribute to the complex etiology of nsCL/P.

Abstract
The disruption of genes involved in epigenetic regulation is well known to cause Intellectual Disability (ID). We reported a custom microarray study that interrogated among others, the epigenetic regulatory gene-class, at single exon resolution. Here we elaborate on identified intragenic CNVs involving epigenetic regulatory genes; specifically discussing those in three genes previously unreported in ID etiology-ARID2, KDM3A, and ARID4B. The changes in ARID2 and KDM3A are likely pathogenic while the ARID4B variant is uncertain. Previously, we found a CNV involving only exon 6 of the JARID2 gene occurred apparently de novo in seven patients. JARID2 is known to cause ID and other neurodevelopmental conditions. However, exon 6 of this gene encodes one of a series of repeated motifs. We therefore, investigated the impact of this variant in two cohorts and present a genotype-phenotype assessment. We find the JARID2 exon 6 CNV is benign, with a high population frequency (>14%), but nevertheless could have a contributory effect. We also present results from an interrogation of the exomes of 2,044 patients with neurocognitive phenotypes for the incidence of potentially damaging mutation in the epigenetic regulatory gene-class. This paper provides a survey of the fine-scale CNV landscape for epigenetic regulatory genes in the context of ID, describing likely pathogenic as well as benign single exon imbalances. © 2016 Wiley Periodicals, Inc.

Late-stage differentiation of embryonic pancreatic β-cells requires Jarid2. Sci Rep 2017; 7:11643.

Abstract
Jarid2 is a component of the Polycomb Repressor complex 2 (PRC2), which is responsible for genome-wide H3K27me3 deposition, in embryonic stem cells. However, Jarid2 has also been shown to exert pleiotropic PRC2-independent actions during embryogenesis. Here, we have investigated the role of Jarid2 during pancreas development. Conditional ablation of Jarid2 in pancreatic progenitors results in reduced endocrine cell area at birth due to impaired endocrine cell differentiation and reduced prenatal proliferation. Inactivation of Jarid2 in endocrine progenitors demonstrates that Jarid2 functions after endocrine specification. Furthermore, genome-wide expression analysis reveals that Jarid2 is required for the complete activation of the insulin-producing β-cell differentiation program. Jarid2-deficient pancreases exhibit impaired deposition of RNAPII-Ser5P, the initiating form of RNAPII, but no changes in H3K27me3, at the promoters of affected endocrine genes. Thus, our study identifies Jarid2 as a fine-tuner of gene expression during late stages of pancreatic endocrine cell development. These findings are relevant for generation of transplantable stem cell-derived β-cells.

Abstract
Cleft palate only (CPO) is one of the most common congenital malformations worldwide. The etiopathogenesis of CPO is not completely understood. Environmental factors, such as smoking, alcohol consumption, intake of drugs during pregnancy, advanced paternal age, have been demonstrated to be a risk of CPO, but conflicting results have also been published. Insufficient intake of folic acid during the pregnancy has been suggested to increase the risk for CPO. The demonstrated risk for siblings and the higher risk for monozygotic twins suggest a genetic etiopathogenesis for CPO. In some cases of CPO a prevalent mode of inheritance has been reported, but oligogenic models with reduced penetrance, and the risk related to environmental factors have also been proved. One of the first manifestations associated with CPO is difficulty with feeding. Aerophagia is a problem in these infants with CPO and requires more frequent burping and slower feeding. The inability to generate intraoral breath pressure due to nasal air emission in CPO children frequently manifests as articulation difficulties, particularly consonant weakness, and unintelligible speech. Hearing disorders are prevalent among individuals with CPO, as a result of chronic otitis media with effusion due to eustachian tube dysfunction. A multidisciplinary team is essential to manage the many aspects of CPO. In treating CPO, the reconstructive surgeon works in cooperation with otolaryngologists, dentists and orthodontists, speech pathologists, audiologists, geneticists, psychiatrists, maxillofacial surgeons, social workers, and prosthodontists. CPO can be considered a genetically complex disease, but new knowledge and new therapeutic approaches have greatly improved the quality of life of these children. Prenatal diagnosis is an important step in the treatment of this disease.

Abstract
Cleft of the lip and/or palate (CL±P) is the most common congenital craniofacial anomaly affecting around 1 in 700 live births worldwide. Clefts of the human face can be classified anatomically as cleft lip only (CL), cleft palate only (CP), cleft lip and palate (CLP) or a combined group of cleft lip with or without cleft palate (CL±P), based on differences in embryologic development. CL±P has a genetic base and several linkage and association analyses have been performed in order to obtain important information about the role of candidate genes in its onset; not less important are gene-environment interactions that play an increasing role in its aetiology. In CL±P, several loci have been seen associated with the malformation, and, in some cases, a specific gene mapping in a locus has also been identified as susceptibility factor. In CP, one gene has been found, but many more are probably involved. In this short review the genetic studies carried out on CL±P, and the interaction with environmental factors (alcohol, smoking, drugs) are discussed.

Abstract
Partial trisomy of the short arm of chromosome 6 is a rare and clinically distinct syndrome. The breakpoints have been found to be variable ranging from bands 6p11 to 6p25. This study reports partial trisomy for 6p22.3→pter in a 2-year-old boy referred with a complaint of developmental delay and facial dysmorphism. Conventional cytogenetic analysis showed the presence of an abnormal chromosome 5 resulting from an unbalanced translocation in the proband. Array comparative genomic hybridization revealed trisomy of distal 6p which was confirmed by fluorescence in situ hybridization using subtelomeric probes for chromosomes 5 and 6. A comparison of the phenotypic features in similar cases of trisomy for different segments of 6p will facilitate an accurate karyotype-phenotype correlation and, subsequently, in the identification of the candidate genes through molecular characterization of the potential genes mapped to these loci.

Abstract
BACKGROUND Variants in the cysteine-rich secretory protein LCCL domain containing 2 gene (CRISPLD2) and in the jumonji, AT-rich interaction domain 2 gene (JARID2) were previously shown to influence non-syndromic oral cleft susceptibility. Herein, we performed a case-control study to examine the potential association of single-nucleotide polymorphisms (SNPs) in CRISPLD2 and JARID2 with non-syndromic cleft lip and/or palate (NSCL/P) in the Brazilian population. Given the ethnicity-dependent genetic predisposition to NSCL/P, we performed a structured analysis taking into account the genomic ancestry variation of each individual. METHODS Four SNPs in CRISPLD2 (rs1546124, rs8061351, rs2326398, and rs4783099) and four in JARID2 (rs915344, rs2299043, rs2237138, and rs2076056), that were previously reported to be associated with NSCL/P, were genotyped in 785 Brazilian patients with NSCL/P (549 with cleft lip with or without cleft palate-NSCL ± P, and 236 with cleft palate only-NSCPO) and 693 unaffected Brazilian controls. Genomic ancestry was assessed with a set of 40 biallelic short insertion/deletion variants previously validated as ancestry informative markers of the Brazilian population. RESULTS After adjustment of ancestry variations, allelic analysis revealed marginal associations between the CRISPLD2 rs4783099 T allele and increased risk for NSCPO (OR: 1.31, 95% CI: 1.05-1.62, P = 0.01) and between JARID2 rs2237138 and decreased NSCL ± P risk (OR: 0.80, 95% CI: 0.67-0.97, P = 0.02). Haplotype analysis indicated a lack of association between JARID2 haplotypes and non-syndromic oral cleft risk. CONCLUSIONS Our results suggest that CRISPLD2 rs4783099 may represent a risk factor for NSCPO while JARID2 rs2237138 shows a protective effect against NSCL ± P in the Brazilian population.

Abstract
Jarid2 is part of the Polycomb Repressor complex 2 (PRC2) responsible for genome-wide H3K27me3 deposition. Unlike other PRC2-deficient embryonic stem cells (ESCs), however, Jarid2-deficient ESCs show a severe differentiation block, altered colony morphology, and distinctive patterns of deregulated gene expression. Here, we show that Jarid2−/− ESCs express constitutively high levels of Nanog but reduced PCP signaling components Wnt9a, Prickle1, and Fzd2 and lowered β-catenin activity. Depletion of Wnt9a/Prickle1/Fzd2 from wild-type ESCs or overexpression of Nanog largely phenocopies these cellular defects. Co-culture of Jarid2−/− with wild-type ESCs restores variable Nanog expression and β-catenin activity and can partially rescue the differentiation block of mutant cells. In addition, we show that ESCs lacking Jarid2 or Wnt9a/Prickle1/Fzd2 or overexpressing Nanog induce multiple ICM formation when injected into normal E3.5 blastocysts. These data describe a previously unrecognized role for Jarid2 in regulating a core pluripotency and Wnt/PCP signaling circuit that is important for ESC differentiation and for pre-implantation development. ESCs lacking Jarid2 show constitutive Nanog expression ESCs lacking Jarid2 have reduced PCP/Wnt signaling Co-culture of Jarid2-null and WT ESCs restores differentiation capability Jarid2-null ESCs form more than one ICM upon injection to E3.5 mouse blastocysts

Abstract
OBJECTIVES Non-syndromic orofacial clefts (NSOC) are the most common human craniofacial malformation in all worldwide populations. Recently, the jumoji AT-rich interaction domain 2 (JARID2) had been reported to be a novel candidate gene for non-syndromic cleft lip with or without cleft palate (CL/P). The SNPs rs2076056, rs2237138 and rs2299043 in JARID2 were highly significant in Italian families. MATERIAL AND METHODS In the current research, a case-control study was conducted to examine the association between these three SNPs and NSOC in a northern Chinese Han population. Genotyping of the three SNPs were performed using SNaPshot minisequencing technique. RESULTS Distribution of rs2237138 genotypes in CL/P group was different from those in the control group (P = 0.04), but significant results did not persist after Benjamini and Hochberg false discovery rate (FDR) correction for multiple tests. Further logistic regression analysis showed that rs2237138 GG genotypes were associated with decreased CL/P susceptibility (OR = 0.34, 95% CI = 0.13-0.84), compared with the AA wild-type homozygote. For the haplotype CGT, a statistically difference was identified between the CL/P group and controls (P = 0.04). And carriers of GAT haplotype were considered to be less frequent among cleft palate only group as compared to controls (P = 0.02). However, both of the haplotypes association did not remain statistically significant after Benjamini and Hochberg FDR correction. CONCLUSION We got a weak association between these polymorphisms and NSOC in both single-marker and haplotype analyses. Our data further strengthen the conclusion that JARID2 polymorphisms are associated with NSOC susceptibility.

Abstract
Cleft lip or palate (CL/P) is a common facial defect present in 1 : 700 live births and results in substantial burden to patients. There are more than 500 CL/P syndromes described, the causes of which may be single-gene mutations, chromosomopathies, and exposure to teratogens. Part of the most prevalent syndromic CL/P has known etiology. Nonsyndromic CL/P, on the other hand, is a complex disorder, whose etiology is still poorly understood. Recent genome-wide association studies have contributed to the elucidation of the genetic causes, by raising reproducible susceptibility genetic variants; their etiopathogenic roles, however, are difficult to predict, as in the case of the chromosomal region 8q24, the most corroborated locus predisposing to nonsyndromic CL/P. Knowing the genetic causes of CL/P will directly impact the genetic counseling, by estimating precise recurrence risks, and the patient management, since the patient, followup may be partially influenced by their genetic background. This paper focuses on the genetic causes of important syndromic CL/P forms (van der Woude syndrome, 22q11 deletion syndrome, and Robin sequence-associated syndromes) and depicts the recent findings in nonsyndromic CL/P research, addressing issues in the conduct of the geneticist.

Abstract
Histone modifications are thought to regulate chromatin structure, transcription and other nuclear processes. Histone methylation was originally believed to be an irreversible modification that could only be removed by histone eviction or by dilution during DNA replication. However, the isolation of two families of enzymes that can demethylate histones has changed this notion. The biochemical activities of these histone demethylases towards specific Lys residues on histones, and in some cases non-histone substrates, have highlighted their importance in developmental control, cell-fate decisions and disease. Their ability to be regulated through protein-targeting complexes and post-translational modifications is also beginning to shed light on how they provide dynamic control during transcription.

Abstract
Unraveling of factors involved in multifactorial diseases is a great challenge. Different approaches can be contemplate and applied to a variety of congenital malformations. In the present investigation TFAP2A has been considered a good candidate gene for nonsyndromic cleft lip with or without cleft palate (NSCLP) aetiology, basing on a sum of considerations. TFAP2A has been seen involved in orofacial development in mice; it is located in the NSCLP candidate region 6p24; it codes for a transcription factor which regulates expression of IRF6, a gene implied in NSCLP; finally, it is embroiled in the branchiooculofacial syndrome, that includes clefting as feature. A family based association analysis was performed with a sample study of 405 NSCLP triads. Evidence of association was obtained with both single marker and haplotype analyses, thus providing a support for TFAP2A in NSCLP aetiology.

Abstract
Methylation of histone tails is believed to be important for the establishment and inheritance of gene expression programs during development. Jarid2/Jumonji is the founding member of a family of chromatin modifiers with histone demethylase activity. Although Jarid2 contains amino acid substitutions that are thought to abolish its catalytic activity, it is essential for the development of multiple organs in mice. Recent studies have shown that Jarid2 is a component of the polycomb repressive complex 2 and is required for embryonic stem (ES) cell differentiation. Here, we discuss current literature on the function of Jarid2 and hypothesize that defects resulting from Jarid2 deficiency arise from a failure to correctly prime genes in ES cells that are required for later stages in development.
