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.

Chen C, Guo Q, Shi J, Jiao X, Lv K, Liu X, Jiang Y, Hui X, Song T. Genetic variants of MGMT, RHPN2, and FAM49A contributed to susceptibility of nonsyndromic orofacial clefts in a Chinese population. J Oral Pathol Med 2018; 47:796-801. [PMID: 29949196 DOI: 10.1111/jop.12758] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2018] [Revised: 06/17/2018] [Accepted: 06/25/2018] [Indexed: 12/20/2022]
Abstract
BACKGROUND The role of underlying genetic factors in the pathogenesis of nonsyndromic orofacial clefts (NSOC) remains poorly understood. Although genomewide association studies (GWASs) of NSOC have successfully identified a large number of novel genetic risk loci, association results of replication studies are inconsistent across different populations. METHODS Six single nucleotide polymorphisms (SNPs) (rs7922405 at 10q26.3, rs73039426 at 19q13.11, rs7552 at 2p24.2, rs1788160 at 8q22.2, rs9381107 at 6p24.3, and rs17095681 at 10q25.3) were analyzed for an association with NSOC in 1062 participants of Chinese descent (596 patients and 466 controls). We applied the multifactor dimensionality reduction (MDR) method to detect potential gene-gene (G × G) interactions in the six SNPs. RESULTS The genotype or allele frequencies of SNPs rs7922405, rs73039426, and rs7552 showed significant differences between the controls and patients with NSOC, whereas no association was shown between three SNPs (rs1788160, rs17095681, and rs9381107) and NSOC. MDR analysis did not reveal significant G × G interactions for susceptibility to NSOC. CONCLUSION We confirmed that three genes (rs7922405 of MGMT, rs73039426 of RHPN2, and rs7552 of FAM49A) may contribute to NSOC in Chinese populations. MGMT and RHPN2 are associated with NSOC, which is herein demonstrated for the first time.

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. [PMID: 29374328 DOI: 10.1007/s00784-018-2350-0] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2017] [Accepted: 01/17/2018] [Indexed: 12/24/2022]
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
BACKGROUND Non-syndromic cleft lip with or without cleft palate (NSCL/P) is a common orofacial congenital anomaly. The objective of the present study was to analyze the association of single nucleotide polymorphisms (SNPs) in the NAT2 and EGF61genes with NSCL/P in a Chinese population. METHODS The frequencies of NAT2 (rs1799929)and EGF61 (rs4444903) gene variations were examined in a group of 285 NSCL/P patients and in 315 controls. Peripheral venous blood samples were collected for DNA extraction. Genotyping of the 2 SNPs was carried out using a mini sequencing (SNaPshot) method. Data were analyzed using the chi-square test. RESULTS We found a significant association between the EGF61 (rs4444903) and NSCL/P (P = .01) genes.Conversely, NAT2 (rs1799929) was not significantly different between the cases and the control group.The genotype frequencies of rs4444903GA showed a significant difference compared with GG genotype as a reference (odds ratio = 0.59; 95% confidence interval: 0.42-0.84, P = .01). CONCLUSION Our study showed that the EGF61 rs4444903GA genotype had a decreased risk of NSCL/P. Our data provides further evidence regarding the role of EGF61 variations in the development of NSCL/P in families of the studied populations.

Brazilian multicenter study of association between polymorphisms in CRISPLD2 and JARID2 and non-syndromic oral clefts. J Oral Pathol Med 2016; 46:232-239. [PMID: 27328068 DOI: 10.1111/jop.12470] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 05/25/2016] [Indexed: 12/13/2022]
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.
