Risk and Resilience Variants in the Retinoic Acid Metabolic and Developmental Pathways Associated with Risk of FASD Outcomes. Biomolecules 2024; 14:569. [PMID: 38785976 PMCID: PMC11117505 DOI: 10.3390/biom14050569] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2024] [Revised: 05/01/2024] [Accepted: 05/07/2024] [Indexed: 05/25/2024] Open
Abstract
Fetal Alcohol Spectrum Disorder (FASD) is a common neurodevelopmental disorder that affects an estimated 2-5% of North Americans. FASD is induced by prenatal alcohol exposure (PAE) during pregnancy and while there is a clear genetic contribution, few genetic factors are currently identified or understood. In this study, using a candidate gene approach, we performed a genetic variant analysis of retinoic acid (RA) metabolic and developmental signaling pathway genes on whole exome sequencing data of 23 FASD-diagnosed individuals. We found risk and resilience alleles in ADH and ALDH genes known to normally be involved in alcohol detoxification at the expense of RA production, causing RA deficiency, following PAE. Risk and resilience variants were also identified in RA-regulated developmental pathway genes, especially in SHH and WNT pathways. Notably, we also identified significant variants in the causative genes of rare neurodevelopmental disorders sharing comorbidities with FASD, including STRA6 (Matthew-Wood), SOX9 (Campomelic Dysplasia), FDG1 (Aarskog), and 22q11.2 deletion syndrome (TBX1). Although this is a small exploratory study, the findings support PAE-induced RA deficiency as a major etiology underlying FASD and suggest risk and resilience variants may be suitable biomarkers to determine the risk of FASD outcomes following PAE.

Prevalence and associated factors of myofascial pain in orthognathic patients with skeletal class II malocclusion. Oral Maxillofac Surg 2023; 27:25-31. [PMID: 35262814 DOI: 10.1007/s10006-022-01046-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2021] [Accepted: 02/01/2022] [Indexed: 06/14/2023]
Abstract
UNLABELLED Orthognathic patients with skeletal class II malocclusion frequently suffer from myofascial pain (MP). PURPOSE This study aimed to evaluate the prevalence and associated factors of MP in these patients. METHODS This cross-sectional study was performed in adult patients with skeletal Class II malocclusion requiring orthognathic surgery. They were divided according to the presence or absence of MP. The predictor variables were craniofacial morphology, sex, temporomandibular disorders, chronic pain, depression, and polymorphisms of dopamine receptors DRD2 (rs6275 and rs6276) and ANKK1 (rs1800497) genes. Data were submitted to statistical analyses using the linear regression model and Poisson regression with a significance level of 0.05. RESULTS Sixty-five individuals were selected, of which 50 (76.92%) were females. A total of 21 (32.3%) patients had MP. Individuals with MP showed a decrease in the mandible gonial angle (p = 0.042) and an increased risk of having temporomandibular joint (TMJ) disc displacement (p = 0.003), TMJ pain (p = 0.030), chronic pain (p = 0.001), and severe depression (p = 0.015). Additionally, individuals carrying AA and AG genotypes in rs6275, and CC genotype in rs6276, were more likely to have MP (p < 0.05). CONCLUSION In this study, 32.3% of skeletal class II orthognathic patients had MP, which was associated with a decreased gonial angle, TMJ disc displacement, TMJ pain, chronic pain, depression, and polymorphisms in the DRD2 gene.

Genetic overlap between temporomandibular disorders and primary headaches: A systematic review. JAPANESE DENTAL SCIENCE REVIEW 2022; 58:69-88. [PMID: 35242249 PMCID: PMC8881721 DOI: 10.1016/j.jdsr.2022.02.002] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2021] [Revised: 12/18/2021] [Accepted: 02/07/2022] [Indexed: 12/14/2022] Open
Abstract
Primary headache disorders (PHD), specifically migraine, are strongly associated with temporomandibular disorders (TMD), sharing some patterns of orofacial pain. Both disorders have significant genetic contributions already studied. PRISMA guidelines were followed to conduct this systematic review, which comprehensively summarize and discuss the genetic overlap between TMD and PHD to aid future research in potential therapy targets. This review included eight original articles published between 2015 and 2020, written in English and related to either TMD and/or PHD. The genes simultaneously assessed in PHD and TMD studies were COMT, MTHFR, and ESR1. COMT was proved to play a critical role in TMD pathogenesis, as all studies have concluded about its impact on the occurrence of the disease, although no association with PHD was found. No proof on the impact of MTHFR gene regulation on either TMD or PHD was found. The most robust results are concerning the ESR1 gene, which is present in the genetic profile of both clinical conditions. This novel systematic review highlights not only the need for a clear understanding of the role of ESR1 and COMT genes in pain pathogenesis, but it also evaluates their potential as a promising therapeutic target to treat both pathologies.

Temporomandibular disorder in construction workers associated with ANKK1 and DRD2 genes. Braz Dent J 2022; 33:12-20. [PMID: 36043564 PMCID: PMC9645185 DOI: 10.1590/0103-6440202204963] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2022] [Accepted: 07/06/2022] [Indexed: 11/30/2022] Open
Abstract
The study aimed to explore the influence of genetic polymorphisms in ANKK1 and
DRD2 on the signs and symptoms of temporomandibular disorder (TMD) in
construction workers. This cross-sectional study included only male subjects.
All construction workers were healthy and over 18 years age. Illiterate workers
and functionally illiterate workers were excluded. The diagnosis of TMD was
established according to the Research Diagnostic Criteria for TMD (RDC/TMD).
Genomic DNA was used to evaluate the genetic polymorphisms ANKK1 (rs1800497) and
DRD2 (rs6275; rs6276) using Real-Time PCR. Chi-square or Fisher exact tests were
used to evaluate genotypes and allele distribution among the studied phenotypes.
The established alpha of this study was 5%. The sample included a total of 115
patients. The age of the patients ranged from 19 to 70 years (mean age 38.2;
standard deviation 11.7). Chronic pain (87.7%), disc displacement (38.2%), and
joint inflammation (26.9%) were the most frequently observed signs and symptoms.
The genetic polymorphism rs6276 in DRD2 was associated with chronic pain
(p=0.033). In conclusion, our study suggests that genetic polymorphisms in DRD2
and ANKK1 may influence TMD signs and symptoms in a group of male construction
workers.

Lira SS, Ahammad I. A comprehensive in silico investigation into the nsSNPs of Drd2 gene predicts significant functional consequences in dopamine signaling and pharmacotherapy. Sci Rep 2021; 11:23212. [PMID: 34853389 PMCID: PMC8636637 DOI: 10.1038/s41598-021-02715-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2021] [Accepted: 11/18/2021] [Indexed: 01/01/2023] Open
Abstract
DRD2 is a neuronal cell surface protein involved in brain development and function. Variations in the Drd2 gene have clinical significance since DRD2 is a pharmacotherapeutic target for treating psychiatric disorders like ADHD and schizophrenia. Despite numerous studies on the disease association of single nucleotide polymorphisms (SNPs) in the intronic regions, investigation into the coding regions is surprisingly limited. In this study, we aimed at identifying potential functionally and pharmaco-therapeutically deleterious non-synonymous SNPs of Drd2. A wide array of bioinformatics tools was used to evaluate the impact of nsSNPs on protein structure and functionality. Out of 260 nsSNPs retrieved from the dbSNP database, initially 9 were predicted as deleterious by 15 tools. Upon further assessment of their domain association, conservation profile, homology models and inter-atomic interaction, the mutant F389V was considered as the most impactful. In-depth analysis of F389V through Molecular Docking and Dynamics Simulation revealed a decline in affinity for its native agonist dopamine and an increase in affinity for the antipsychotic drug risperidone. Remarkable alterations in binding interactions and stability of the protein-ligand complex in simulated physiological conditions were also noted. These findings will improve our understanding of the consequence of nsSNPs in disease-susceptibility and therapeutic efficacy.
