Genetic risk factor’s for Periodontal Disease Could my periodontal disease be genetic? (1986) 2 on Sri Lankan tea workers. 1. The FcγRIIIb is the major IgG receptor of neutrophils 54. Gene encoding for IL-10 are located on chromosome 1q31-q32, in a cluster with closely related interleukin genes, including IL-19, IL-20, and IL-24. The information presented in this website has been collected from various leading journals, books and websites. Kornman KS, di Giovine FS. the genetic constitution of an organism. One study done on HLA-DR molecules in patients with periodontitis found a significant association between several DRB1 alleles and the disease 62, but another study 63 found no association between the presence of HLA-DQB1 in European Caucasians and the occurrence of early-onset periodontitis. Panel (B) summarizes the complexity of periodontitis, The vicious cycle of the “ecological catastrophe” driven by an aberrant host response in periodontitis, A generic multi‐causality model for periodontitis, where 5 clusters of causal (risk) factors are playing a role simultaneously, (epi)genetic factors (light blue), lifestyle factors (orange), comorbidities (systemic diseases) (gray), microbial communities, ie, dental biofilms (yellow) and other factors (tooth and dention related and stochasticity) (dark blue). Epigenome refers to, Out of these three mechanisms, enzymatic DNA methylation of the C-5 position of cytosine residues in the CpG islands of the promoter region of a gene is considered as the most important epigenetic mechanisms in mammals, In the eukaryotic cells, the DNA is organized in a highly conserved structural polymer termed chromatin. Variations in any number or combination of genes that control the development … COVID-19 is an emerging, rapidly evolving situation. The cathepsin C gene (11q14.2) spans 4.7 kb and has seven exons, Diagnosis of periodontal disease activity by genetic analysis, Genetic analysis can be used to detect the activity of genes at the active and inactive disease sites. Contents available in the book………, Telocentric: Centromere is on one end, so no p arm is present, Acrocentric: Centromere is very near to the end, so chromosome has a very small p arm, Submetacentric: Centromere is close to the middle of the chromosome, so p arm is just a little smaller than q arm. It is produced by a variety of cells, which include monocytes/macrophages, dendritic cells, B-lymphocytes (particularly the CD5+ B cells), various subsets of CD4+ and CD8+ T-cells 47 and also by human, Leukocytes derived from both the myeloid and lymphoid lineages express receptors (FcγR) for the constant (Fc) region of immunoglobulin G molecules, In this polymorphism, there is a transition of G to A in the FcγRIIa gene, which results in the substitution of histidine (H) (N-allele) for arginine (R) (R-allele) at amino acid position 131 of the receptor. A study done on Japanese population demonstrated that MMP-1 and⁄or MMP-3 single nucleotide polymorphisms were not associated with susceptibility to periodontitis 78. So, conclusions drawn from the above discussion are 35: TNF-α is a potent immunomodulator and proinflammatory cytokine that has been implicated in the pathogenesis of the autoimmune and infectious diseases.

USA.gov. Along with palmer planter hyperkeratosis, Haim-Munk syndrome has additional features like arachnodactyly, acro-osteolysis, atrophic changes of nails and deformity of fingers. When the genetic models of transmission are compared, important information about the mode of transmission (e.g. One study has demonstrated that FcγRIIIa N-allele (V158) is a putative risk factor for periodontitis, in particular for aggressive periodontitis in a group of Dutch patients, Various gene polymorphisms which have been investigated for their role in periodontal disease, In neutrophils, FcγRIIIb exists in two allelic forms, NA1, and NA2. These repeated base patterns range in size up to several hundreds of base pairs, known as “variable number of tandem repeats” (VNTRs or “minisatellites”). Some very informative twin studies are discussed here. Periodontitis is a chronic bacterial inflammatory disease that affects tissues supporting the teeth. New research led by an international team, including researchers at the University of Bristol, suggests hereditary traits and factors such as obesity, education and personality could play a … One study done on patients with Brazilian background showed that the MMP-1 (-1607) 2G/2G genotype was more frequently observed in 26 patients with severe chronic periodontitis than in 24 patients with moderate chronic periodontitis and 37 controls 76. The shared genes suggest that periodontitis is not causally related to atherosclerotic diseases, but rather both conditions are sequelae of similar (the same?) Studies have investigated DNA methylation of inflammatory cytokines in various forms of periodontitis. 1994 Oct;6(1):7-25. J Clin Periodontol. Genetic factors in the pathogenesis of periodontitis. 2020 Jun 19;21(12):4389. doi: 10.3390/ijms21124389. Genetic factors, along with environmental factors are strongly associated with the development and progression of periodontal diseases. The human VDR gene is located on chromosome 12q12–q14, with a cluster of polymorphisms associated with BsmI, ApaI and TaqI sites. (2008) 81 analyzed the whole genome to show the differential gene expression of healthy and diseased periodontal sites. A locus (plural loci) is the specific location of a gene or DNA sequence on a chromosome. Both TLR2 and TLR4 use CD14 as a co-receptor. Periodontitis may have a slow (Grade A), … A nucleotide is an organic molecule made up of a nucleotide base, a five-carbon sugar (ribose or deoxyribose) and at least one phosphate group. Another study was done by Michalowicz et al. Individuals with defective collagen Types IV and VIII, inherit this defect in an autosomal dominant manner and have an increased susceptibility to periodontitis, In this syndrome abnormalities of the epidermal keratinocytes is seen. Contents available in the book………. doi: 10.1111/jcpe.12940. In this study, dizygous twins reared apart (dizygous-A) and reared together (dizygous-T) and monozygous twins reared apart (monozygous-A) and reared together (monozygous-T) were examined for the mean ……. As far as TLR2 and TLR4 are concerned, their genes have been located on chromosome 4q32 and 9q32-q33, respectively. IL-1α is a regulator of intracellular events and a mediator of local inflammation, whereas Il-1β is primarily an extracellular protein, released from the cells 25. Due to mutations of this gene, there is a loss of protease activity of the cathepsin C protein. Identification of candidate genes and their use as periodontal disease biomarkers is the potential clinical application of the research done so far in this field. Humans have a total of 23 pairs of chromosomes, out of which one pair which determines the sex of the individual is called, the sex chromosome pair. Tobacco users also are at increased risk for periodontal disease. The most studied polymorphisms in IL-4 are IL-4 -590 promoter polymorphism and 70-bp VNTR polymorphism. In this syndrome abnormalities of the epidermal keratinocytes is seen 12. Periodontal manifestations include early-onset periodontitis 12, 13. aberrant inflammatory pathways. Regions are divided into bands and bands into sub-bands, for example, 17p22.3 indicates chromosome 17, short arm region 2, band 2, sub-band 3. Contents available in the book…….

In one study, it was found that the IL-8 promoter was hypomethylated in oral epithelial cells from individuals with generalized aggressive periodontitis compared with healthy controls, Can periodontal pathogens influence the epigenetic expression of cells of the periodontium? Genetics and epigenetics can be defined as the processes by which genes were expressed or suppressed through polymorphism, (de)methylation, or (de)acetylation. The single base transition polymorphism (G to A) at the -308 base site (TNF2) was found to result in a significantly higher transcription of the rare allele, TNF2, using a reporter gene construct 37. HERITABILITY OF GINGIVITIS  It is feasible that genes implicated in the regulation of inflammatory process of periodontal tissues associated with plaque accumulation may play a role in explaining the individual variability in the severity of both plaque-induced gingivitis and destructive periodontitis (Dashash et al. (1976) 16 based on a preponderance of female probands. It has been found that in periodontitis, epigenetic modifications during inflammation occur locally at the biofilm-gingival interface around the teeth. Antigen-recognition related gene polymorphism. Contents available in the book……. -, Morelli T, Moss KL, Beck J, et al. autosomal, X-linked, dominant, recessive, complex, An X-linked inheritance of aggressive periodontitis (Grade C periodontitis) was proposed by. Results demonstrated a higher prevalence of TaqI RFLP (t) in the patients with localized aggressive periodontitis than in the controls, It is found in two distinct forms: membrane CD14 (mCD14), expressed primarily on the surface of monocytes/ macrophages and neutrophils, and a soluble form (sCD14) that lacks the glycosylphosphatidylinositol anchor. Contents available in the book……. The linkage analysis studies are based on the fact that alleles at syntenic gene loci in close proximity on the same chromosome tend to be passed together from generation to generation (i.e. The authors found thousands of up-regulated and down-regulated genes at the diseased sites as compared to healthy sites. Periodontology 2000. Clinical manifestations of this condition also include epidermolysis bullosa and poikiloderma congenitale. Genetic factors play a role in the aetiology of periodontitis, and genetics contributes to one of at least five areas of casual factors. Interleukin‐1 genotypes and the association between periodontitis and cardiovascular disease. During the same period, the importance of genetic variations in determining the development and severity of periodontal disease, with genetic influences accounting for as much as ……. Periodontal diseases are multifactorial in nature. Present knowledge suggests that genetic polymorphism is associated with the pathogenesis of periodontal diseases. It is a relatively permanent change in hereditary material involving either a physical change in chromosome relations or a biochemical change in the codons that make up genes. Humans have 23 pairs of chromosomes, 46 in all: 44 autosomes and two sex chromosomes. However, the prevalence is dramatically lower in Chinese (2.3%) and thus the usefulness of the ‘composite genotype’ of allele 2 of both interleukin (IL)-1α (+ 4845) and interleukin (IL)-1β (+ 3954) for determining susceptibility in Chinese patients is dubious 23. PMID: 30975946 [Indexed for MEDLINE] However, IL-6 promoter was found to be partially methylated in both healthy individuals and patients with periodontitis in spite of the fact that the expression of IL-6 was higher in patients with periodontitis 101. As TNF-α acts synergistically with IL-1, higher production of IL-1 and TNF-α has been associated with enhanced response to infection. According to Mendelian laws, the disease phenotype is manifested over a wide range of environments, and although environmental factors and other genes can modify the clinical presentation, in most cases the mutation will manifest in a remarkably similar phenotype. This condition is characterized by defective bone and teeth mineralization and deficiency of serum and bone alkaline phosphatase activity. 2001 Mar;46(1):2-12. doi: 10.1111/j.1834-7819.2001.tb00267.x. Up to 30% of the population may have some genetic susceptibility to periodontal disease. There is a strong evidence in support of the role of genetic factors in the etiopathogenesis of periodontal diseases. Contents available in the book……. The carriage rate of the FcγRIIIa-F158 allele is lower in Japanese than in Caucasians and African- Americans. It involves the production of specific antibodies by B-lymphocytes directed against particular oral microorganisms and the cell-mediated immune response that involves cytotoxic T-lymphocytes directed against the virus or bacteria-infected cells. Genes IL1A and IL1B control the production of the pro-inflammatory proteins, IL-1α, and IL-1β, respectively. They consist of globular domains with a covalently modifiable N-terminal tail at level of lysine and/or arginine residues. A detailed description of leukocyte adhesion deficiency type I and type II has been given in “Role of neutrophils in host-microbial intractions”. As it is well known that vitamin D plays an important role in calcium and phosphorus metabolism, the polymorphism in vitamin D receptor gene can play a role in periodontal diseases. Segregation analysis are applied to determine whether a trait transmission appears to fit the Mendelian or another mode of genetic transmission. Research on identifying specific genes causing periodontitis may improve and … These polymorphisms lead to hampering of the ability of TLR2 to mediate the response to bacterial components. In eukaryotes, it refers to the process by which a methyl group is covalently added to the carbon (at position 5) of cytosine in the DNA strand. J Clin Periodontol. Most of the studies conclude that there is no evidence for any association between single SNPs of IL-4 and chronic periodontitis 42, 43, however in one study, haplotype T(-590)/T(-33)/allele 2 VNTR (70 base pairs)2 of the IL-4 gene polymorphism was shown to be significantly more frequent in patients with chronic periodontitis than in healthy individuals (17.0% in cases vs. 11.0% in controls; odds ratio 1.85) 44. Heritability estimates for dental caries and sucrose sweetness preference. Histone acetylation- open chromatin, active transcription. Although present in most populations, the risk for periodontal diseases is not uniform for all individuals.  Genes involved in multifactorial diseases are c/a susceptibility genes/ allele. Polymorphisms studied for TLR2 are Arg677Trp and Arg753Gln. Genes are pieces of DNA, and most genes contain the information for making a specific protein. Possessing two different forms of a particular gene, one inherited from each parent. Polymorphonuclear leukocyte, It comprises of a collection of connective tissue disorders characterized by defective collagen synthesis. Histone methylation- closed chromatin, silencing of transcription (generally). To date, 4 genetic loci are shared between atherosclerotic cardiovascular diseases and periodontitis, ie, CDKN2B-AS1(ANRIL), a conserved noncoding element within CAMTA1 upstream of VAMP3, PLG, and a haplotype block at the VAMP8 locus. The genetic basis of periodontitis. Another study showed that three MMP-1 polymorphisms (-1607 1G/2 G, -519 A/G, and -422 A/T) showed only a small effect on Grade A/B periodontitis in the Czech population 77. (2014) 98 found an overall demethylation pattern of the suppressor of cytokine signaling 1 (SOCS1) gene. In one study, it was found that the IL-8 promoter was hypomethylated in oral epithelial cells from individuals with generalized aggressive periodontitis compared with healthy controls 99. Periodontal health and gingival diseases and conditions on an intact and a reduced periodontium: Consensus report of workgroup 1 of the 2017 World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions. Also, the deacetylase inhibitors help in promoting the osteoblast maturation 107. Periodontology 2000. A study done on Japanese population showed that FcγRIIIb R-allele (NA2) was associated with generalized (G)-EOP. Hypermethylation and a decreased transcription of Toll-Like Receptor 2 (TLR 2) in periodontitis tissues have been reported 96. Periodontal disease is a polymicrobial in origin which is highly governed by host response, environmental factors, and genetic factors. The most studied polymorphisms in IL-4 are IL-4 -590 promoter polymorphism and 70-bp VNTR polymorphism. In neutrophils, FcγRIIIb exists in two allelic forms, NA1, and NA2. Antigen – recognition related gene polymorphism: Human leukocyte antigen (HLA) polymorphism: The HLA complex is one of the most important components of the host response. Li Y et al. This is called as, Research done on genetic aspect of periodontal diseases. Contents available in the book………. Host response has been divided into two types, namely innate and adaptive immune response (“Basic concepts in immunity and inflammation”). (1985) 19 were first to demonstrate the link-age between aggressive periodontitis (Grade C periodontitis) and dentinogenesis imperfecta. There are three types of epigenetic modifications 85, 86. The defect has been possibly localized to chromosome 7q21. 2018;45(Suppl 20):S95‐S111. We recognize that various causative factors determine the immune blueprint and, consequently, the immune fitness of a subject. This review focuses on the genetic aspects of periodontal diseases wherein researchers are currently focusing on genetic evidences to explain the difference in susceptibility to periodontal disease in different individuals. Segregation analysis are applied to determine whether a trait transmission appears to fit the Mendelian or another mode of genetic transmission. Oral and periodontal findings are periodontitis with oral ulcerations. 2017;88:153‐165. Normally, the host lives in a state of homeostasis or symbiosis with the oral microbiome; however, disturbances in homeostatic balance can occur, because of an aberrant host response (inherited and/or acquired during life). This is called as “Restriction fragment length polymorphism” (RFLP). Contents available in the book……. Matrix metalloproteinases (MMP) polymorphisms: In MMP’s a single nucleotide polymorphism in the promoter region -1607 base pair of MMP-1 gene, 5′-GGA-3′, instead of 5′-GAT-3′ has been found to be associated with increased risk of generalized Grade C periodontitis, Cathepsin C functions as a central coordinator for the activation of many serine proteases in inflammatory cells. However, the prevalence is dramatically lower in Chinese (2.3%) and thus the usefulness of the ‘composite genotype’ of allele 2 of both interleukin (IL)-1α (+ 4845) and interleukin (IL)-1β (+ 3954) for determining susceptibility in Chinese patients is dubious, Single nucleotide polymorphisms in periodontal disease. To clarify the possible role of genetic polymorphisms in periodontal diseases, we searched PubMed for studies published on the subject since 1997 up to June 2018 and obtained data from original studies, meta analyzes, and systematic reviews. Contents available in the book………. The condition is clinically characterized by chronic dermatitis (eczematoid rash). 2020 Jul;47 Suppl 22(Suppl 22):61-71. doi: 10.1111/jcpe.13253. 1999 Oct;34(7):353-7. In contrast, Gomez et al. One third of the population have a genetic tendency to develop periodontal disease. Corey et al. In one study, restriction fragment length polymorphism (RFLP) for TaqI in exon 9 in 69 Caucasian patients with aggressive periodontitis and 72 race-matched controls was studied. autosomal, X-linked, dominant, recessive, complex, ……. He proposed that subjects with only one copy of IgG2 allele would develop severe periodontal disease as compared to subjects with 2 copies of high IgG2 response allele with one aggressive periodontal disease allele. Pharmacological agents can be used to revert the effects of epigenetic variations. Or it can be multifactorial where environmental factors also play important role like in periodontitis. Candidate gene is a gene whose chromosomal location is associated with a particular disease or another phenotype. miRNAs and epigenetic factors can cooperate to modulate common targets. The cathepsin C gene (11q14.2) spans 4.7 kb and has seven exons 6, 7. Contents available in the book……. Studies note that specific environmental factors such as race, gender, diabetes, education, smoking, and body mass index (BMI) all increase the severity of periodontal disease. In MMP’s a single nucleotide polymorphism in the promoter region -1607 base pair of MMP-1 gene, 5′-GGA-3′, instead of 5′-GAT-3′ has been found to be associated with increased risk of generalized Grade C periodontitis 75. Genes coding for IL-6 are located on chromosome 7p21. The observable traits or characteristics of an organism, for example, hair color, weight, or the presence or absence of a disease. Many genetic dental/oral abnormalities indicate more complex disorders and are linked to inherited traits and defects, or result from spontaneous genetic mutations. A lot of research has been done to identify the genetic basis of periodontal diseases. FcγRIIa-H131 binds IgG2 immune complexes efficiently, whereas, the FcγRIIa-R131 allotype cannot mediate this interaction 56. SNPs in the gene encoding TNF- α are mainly studied in the promoter region at positions -1031, -863, -367, -308, -238 but also in the coding region in the first intron at position +489. Let us now discuss these polymorphisms in detail. (1997) 22 demonstrated that the occurrence of IL-1A (-889) and\IL-1B (+3954) polymorphisms simultaneously was associated with the severity of chronic periodontitis in non-smoker Caucasians. Under pathologic conditions such as those that occur in periodontal disease, the balance between pro- and anti-inflammation is directed towards proinflammatory activity 24. Contents available in the book………. The gene encoding for IL-4 are located on chromosome 5q31.1. So, we can expect variations in the expression of disease in different populations. https://www.deltadentalins.com/oral_health/are-oral-health-issues-genetic.html It is a chromosome map of a species that shows the position of its known genes and/or markers relative to each other, rather than as specific physical points on each chromosome. Polymorphism in CD14 genes has already been discussed. Can periodontal pathogens influence the epigenetic expression of cells of the periodontium? The linkage analysis studies are based on the fact that alleles at syntenic gene loci in close proximity on the same chromosome tend to be passed together from generation to generation (i.e. J Clin Periodontol. periodontitis showed elevated expression of genes for proteolytic. The workers found no significant differences in IL-1β production in response to any stimulant tested. Nevertheless, because of strong familial aggregation, rapid progression, and early onset of disease, it is clear that genetic factors play a large role in the disease susceptibility of AgP (see Fig. Research to find out the genetic factors involved in the progression of periodontal diseases started with the classical study by Löe et al. 1997 Jun;14(1):202-15. Contents available in the book……. Depending upon the age of the patient at the time of diagnosis, this condition has been recognized in five forms: prenatal (lethal), infantile, childhood, adult, and odontophosphatasia. On the contrary, some studies did not find any difference between the IL-1β production from monocytes from ‘composite genotype’ positive and negative patients. Because of its location, the gene is suspected of causing the disease or another phenotype. This site needs JavaScript to work properly. Contents available in the book……. This question can be answered on the basis of multifactorial etiology of periodontal diseases of which genetics is an important component. -, Fine DH, Patil AG, Loos BG. The three cytokines originally described as the members of the IL-1 family are IL-1α and IL-1β, which have agonist activity, and IL-1Ra, a physiological antagonist to other IL-1 cytokines. Polymorphism in CD14 genes has already been discussed. Hypermethylation and subsequent low transcription of TLR2 in periodontitis tissues were reported 96. It has got anti-inflammatory properties. This polymorphism is a result of nucleotide substitutions resulting in changes in four amino acids, which consequently results in differences in glycosylation. The genes violate Mendel’s law of independent assortment. Studies have investigated DNA methylation of inflammatory cytokines in various forms of periodontitis. Simple tandem repeats (STRs) or Microsatellite repeat polymorphism: This is the polymorphism resulting from two, three, or four nucleotides repeated over some variable number of times.  |  Polymorphisms in the pattern recognition receptor genes: The pathogen-associated molecular patterns (PAMPs) that are expressed on microorganisms are recognized by the innate immune system of the host. Clinical symptoms are a dolicho-cephalic skull and enlarged joints, a delay in walking, short stature and waddling gait. The tendency of genes to be inherited together as a package because of their location near one another on the same chromosome.  Periodontal disease development and progression can be … MicroRNAs (miRNAs) are short, non-coding RNA molecules that mediate RNA silencing and regulate gene expression.
