A major dental enamel-forming protein found in mammals. In humans the protein is encoded by GENES found on both the X CHROMOSOME and the Y CHROMOSOME.
A hard thin translucent layer of calcified substance which envelops and protects the dentin of the crown of the tooth. It is the hardest substance in the body and is almost entirely composed of calcium salts. Under the microscope, it is composed of thin rods (enamel prisms) held together by cementing substance, and surrounded by an enamel sheath. (From Jablonski, Dictionary of Dentistry, 1992, p286)
COLLAGEN DISEASES characterized by brittle, osteoporotic, and easily fractured bones. It may also present with blue sclerae, loose joints, and imperfect dentin formation. Most types are autosomal dominant and are associated with mutations in COLLAGEN TYPE I.
Cylindrical epithelial cells in the innermost layer of the ENAMEL ORGAN. Their functions include contribution to the development of the dentinoenamel junction by the deposition of a layer of the matrix, thus producing the foundation for the prisms (the structural units of the DENTAL ENAMEL), and production of the matrix for the enamel prisms and interprismatic substance. (From Jablonski's Dictionary of Dentistry, 1992)

A condition in which certain opposing teeth fail to establish occlusal contact when the jaws are closed.
An amino acid-specifying codon that has been converted to a stop codon (CODON, TERMINATOR) by mutation. Its occurance is abnormal causing premature termination of protein translation and results in production of truncated and non-functional proteins. A nonsense mutation is one that converts an amino acid-specific codon to a stop codon.
Resorption of calcified dental tissue, involving demineralization due to reversal of the cation exchange and lacunar resorption by osteoclasts. There are two types: external (as a result of tooth pathology) and internal (apparently initiated by a peculiar inflammatory hyperplasia of the pulp).

The image is constructed by detecting the products of specimen interactions that are projected above the plane of the sample, such as backscattered electrons. Although SCANNING TRANSMISSION ELECTRON MICROSCOPY also scans the specimen point by point with the electron beam, the image is constructed by detecting the electrons, or their interaction products that are transmitted through the sample plane, so that is a form of TRANSMISSION ELECTRON MICROSCOPY.
Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations.

Unusual indelible enamel staining following fixed appliance treatment. (1/76)

Two cases are described of indelible enamel staining following fixed appliance therapy. The acquired pigmentation occurred in patients with an identifiable enamel defect prior to treatment. The interaction of factors to cause the staining is discussed and it's prevention in future cases highlighted. Subsequent restoration of the affected teeth is shown.  (+info)

Amelogenin-deficient mice display an amelogenesis imperfecta phenotype. (2/76)

Dental enamel is the hardest tissue in the body and cannot be replaced or repaired, because the enamel secreting cells are lost at tooth eruption. X-linked amelogenesis imperfecta (MIM 301200), a phenotypically diverse hereditary disorder affecting enamel development, is caused by deletions or point mutations in the human X-chromosomal amelogenin gene. Although the precise functions of the amelogenin proteins in enamel formation are not well defined, these proteins constitute 90% of the enamel organic matrix. We have disrupted the amelogenin locus to generate amelogenin null mice, which display distinctly abnormal teeth as early as 2 weeks of age with chalky-white discoloration. Microradiography revealed broken tips of incisors and molars and scanning electron microscopy analysis indicated disorganized hypoplastic enamel. The amelogenin null phenotype reveals that the amelogenins are apparently not required for initiation of mineral crystal formation but rather for the organization of crystal pattern and regulation of enamel thickness. These null mice will be useful for understanding the functions of amelogenin proteins during enamel formation and for developing therapeutic approaches for treating this developmental defect that affects the enamel.  (+info)

A case of amelogenesis imperfecta of deciduous and all permanent teeth. (3/76)

We experienced a case with severe enamel defects of both the deciduous teeth and all the permanent teeth. In order to clarify the etiology of enamel defects in this patient, we performed a DNA analysis in addition to conventional examinations. Although we suspected a variety of systemic factors causing enamel defects, there was no evidence suggesting disturbances of amelogenesis. In the present case, we suspected a mutation in the amelogenin gene and performed nucleotide sequencing of the exons of the amelogenin gene, but we could not find any evidence of mutation. We suggest that a mutation of some other gene related to enamel formation or the adventitious factors contributed to the amelogenesis imperfecta in this case.  (+info)

Mutation of the gene encoding the enamel-specific protein, enamelin, causes autosomal-dominant amelogenesis imperfecta. (4/76)

Amelogenesis imperfecta (AI) is a group of inherited defects of dental enamel formation that shows both clinical and genetic heterogeneity. To date, mutations in the gene encoding amelogenin have been shown to underlie a subset of the X-linked recessive forms of AI. Although none of the genes underlying autosomal-dominant or autosomal-recessive AI have been identified, a locus for a local hypoplastic form has been mapped to human chromosome 4q11-q21. In the current investigation, we have analysed a family with an autosomal-dominant, smooth hypoplastic form of AI. Our results have shown that a splicing mutation in the splice donor site of intron 7 of the gene encoding the enamel-specific protein enamelin underlies the phenotype observed in this family. This is the first autosomal-dominant form of AI for which the genetic mutation has been identified. As this type of AI is clinically distinct from that localized previously to chromosome 4q11-q21, these findings highlight the need for a molecular classification of this group of disorders.  (+info)

Dental enamel formation and its impact on clinical dentistry. (5/76)

The nature of tooth enamel is of inherent interest to dental professionals. The current-day clinical practice of dentistry involves the prevention of enamel demineralization, the promotion of enamel remineralization, the restoration of cavitated enamel where demineralization has become irreversible, the vital bleaching of dental enamel that has become discolored, and the diagnosis and treatment of developmental enamel malformations, which can be caused by environmental or genetic factors. On a daily basis, dental health providers make diagnostic and treatment decisions that are influenced by their understanding of tooth formation. A systemic condition during tooth development, such as high fever, can produce a pattern of enamel defects in the dentition. Knowing the timing of tooth development permits estimates about the timing of the disturbance. The process of enamel maturation continues following tooth eruption, so that erupted teeth can become less susceptible to decay over time. Mutations in the genes encoding enamel proteins lead to amelogenesis imperfecta, a collection of inherited diseases having enamel malformations as the predominant phenotype. Defects in the amelogenin gene cause X-linked amelogenesis imperfecta, and genes encoding other enamel proteins are candidates for autosomal forms. Here we review our current understanding of dental enamel formation, and relate this information to clinical circumstances where this understanding may be particularly relevant.  (+info)

Genetic mutations in certain head and neck conditions of interest to the dentist. (6/76)

This article identifies certain syndromes of the head and neck, which a dentist may see in clinical practice, and relates these syndromes to their sites of mutation on involved genes. This paper is timely with the near completion of the Human Genome Project, the mapping of the entire human genetic material. Knowing the site of the genetic lesion is important in helping clinicians understand the genetic basis for these conditions, and may help in our future understanding of remedies and treatments.  (+info)

Altered amelogenin self-assembly based on mutations observed in human X-linked amelogenesis imperfecta (AIH1). (7/76)

A hallmark of biological systems is a reliance on protein assemblies to perform complex functions. We have focused attention on mammalian enamel formation because it relies on a self-assembling protein complex to direct mineral habit. The principle protein of enamel is amelogenin, a 180-amino acid hydrophobic protein that self-assembles to form nanospheres. We have used independent technical methods, consisting of the yeast two-hybrid (Y2H) assay and surface plasmon resonance (SPR), to demonstrate the importance of amelogenin self-assembly domains. In addition, we have analyzed mutations in amelogenin observed in patients with amelogenesis imperfecta who demonstrate defects in enamel formation. Assessments of self-assembly of these mutant amelogenins by either SPR or Y2H assay yield concordant data. These data support the conclusion that the amelogenin amino-terminal self-assembly domain is essential to the creation of an enamel extracellular organic matrix capable of directing mineral formation. It also suggests that a pathway through which point mutations in the amelogenin protein can adversely impact on the formation of the enamel organ is by disturbing self-assembly of the organic matrix. These data support the utilization of the Y2H assay to search for protein interactions among extracellular matrix proteins that contribute to biomineralization and provide functional information on protein-protein and protein-mineral interactions.  (+info)

Dental development after successful treatment of infantile osteopetrosis with bone marrow transplantation. (8/76)

A 3-week-old boy was diagnosed with congenital osteopetrosis. He underwent a bone marrow transplant at 6 weeks of age. At 3 years of age the primary teeth had all erupted, but the canines and the first molars totally lacked root development. The teeth were smaller in size and had evidence of both enamel hypomineralization and hypoplasia. In the permanent dentition, multiple missing teeth were found. The incisors were conical and the mandibular laterals were extremely small. All permanent teeth had normal eruption. This case shows that dental development and eruption of teeth can be reconstituted in a child with congenital osteopetrosis. Bone marrow transplantation induces normalization of osteoclast function, which is a prerequisite for normal dental development and eruption of teeth.  (+info)

Mutations in human and/or mouse homologs are associated with this disease. Synonyms: AIH1; amelogenesis imperfecta hypomaturationtype with snow-capped teeth; amelogenesis imperfecta type IE; X-linked amelogenesis imperfecta 1; X-linked amelogenesis imperfecta hypoplastic/hypomaturation 1; X-linked enamel hypoplasia
Mutations in the AMELX, ENAM, MMP20, KLK-4, FAM83H, WDR72, C4orf26, SLC24A4 LAMB3 and ITGB6 genes have been found to cause amelogenesis imperfecta (non-syndromic form). AMELX and ENAM encode extracellular matrix proteins of the developing tooth enamel and KLK-4 and MMP20 encode proteases that help degrade organic matter from the enamel matrix during the maturation stage of amelogenesis. SLC24A4 encodes a calcium transporter that mediates calcium transport to developing enamel during tooth development. Less is known about the function of other genes implicated in amelogenesis imperfecta.. Researchers expect that mutations in further genes are likely to be identified as causes of amelogenesis imperfecta.. Types include:. Amelogenesis imperfecta can have different inheritance patterns depending on the gene that is altered. Mutations in the ENAM gene are the most frequent known cause and are most commonly inherited in an autosomal dominant pattern. This type of inheritance means one copy of the ...

Amelogenesis imperfecta (AI) is a group of inherited defects of dental enamel formation that show both clinical and genetic heterogeneity [1]. In its mildest form, AI causes discoloration, while in the most severe presentation the enamel is hypocalcified causing it to be abraded from the teeth shortly after their emergence into the mouth [2]. Both the primary and permanent dentitions may be affected. Enamel findings in AI are highly variable, ranging from deficient enamel formation to defects in the mineral and protein content [3]. Four main types of AI have been described: hypoplastic, hypocalcified, hypomaturation and hypomaturation-hypoplastic with taurodontism [4].. The AI phenotypes vary widely depending on the specific gene involved, the location and type of mutation, and the corresponding putative change at the protein level [5]. Different inheritance patterns such as X-linked, autosomal dominant and autosomal recessive types have been reported and 14 subtypes of AI are recognized ...
Amelogenesis imperfecta is an inherited defect of dental enamel formation that shows both clinical and genetic heterogeneity. In the hypoplastic type of AI, the enamel is of normal hardness but does not develop to normal thickness. The thinness of the enamel makes the teeth appear small. Radiographically, enamel contrasts normally from dentin. The surface of the enamel can vary, showing smooth, rough, pitted, or local forms (Witkop, 1988).

Amelogenesis imperfecta is a group of rare genetic conditions in which the outer layer of the teeth (enamel) fails to develop properly.
Amelogenesis imperfecta, type IV (AI4; MIM 104510) and trichodentoosseus syndrome (TDO; MIM 190320) are related disorders characterized by enamel hypoplasia and taurodontism. Tooth abnormalities are the only clinical features seen in individuals with AI4, while individuals with TDO also have hair, nail, and bone abnormalities. The additional findings seen in TDO may include dolichocephaly, kinky or curly hair, brittle nails, and a mild to moderate increase in bone density of the skull, spine and long bones. AI4 and TDO are autosomal dominant disorders caused by mutations in the DLX3 gene. DLX3 encodes the distal-less homeobox 3 protein, a transcription factor involved in regulation of gene expression during the development of various tissues.. Read less ...

Amelotin is an enamel-specific gene product, and its expression under normal circumstances is limited to maturation-stage (or late-stage) amelogenesis. The altered pattern of amelotin gene expression is achieved by creating transgenic animals in which the amelogenin gene promoter is used to drive amelotin. This study sets out to analyze transgenic animals in which amelotin is expressed throughout all stages of enamel formation (amelogenesis). This thesis will include an introduction and background in tooth development (including amelogenesis), and present results demonstrating animal genotype confirmation, transgene expression profiles by immunohistochemical and Western analysis and enamel phenotype using electron microscopy. We hypothesized that The transgene will be functional, and that the amelotin transgene will be expressed throughout all stages of amelogenesis, resulting in an abnormal enamel structure. Data from immunohistochemical studies showed amelotin to be expressed throughout all ...
BACKGROUND: Cytomegalovirus (CMV) is one of the most common causes of major birth defects in humans. Of the approximately 8400 children born each year in the U.S. with CMV-induced birth defects, more than 1/3 of these children exhibit hypoplasia and hypocalcification of tooth enamel. ❧ OBJECTIVE: Our objective was to initiate the investigation of the pathogenesis of CMV-induced tooth defects and examine the effects of CMV infection on progressive tooth differentiation and amelogenesis. ❧ METHODS: Mouse Cap and Bell stage mandibular first molars were infected with mouse CMV (mCMV) in vitro in a chemically-defined organ culture system and analyzed utilizing histological and immunolocalization methodologies. ❧ RESULTS: CMV infection of embryonic mouse mandibular first molars in vitro induces tooth dysmorphogenesis and enamel defects in a developmental stage- and duration-dependent manner. Initial protein localization studies suggest that the pathogenesis is mediated through NF-κB signaling ...
Author(s): Katsura, Kaitlin A | Advisor(s): Den Besten, Pamela | Abstract: Amelogenesis Imperfecta (AI) is a clinical diagnosis that encompasses a group of genetic mutations, each affecting processes involved in tooth enamel formation and thus, result in various enamel defects. The hypomaturation enamel phenotype has been described for mutations involved in the later stage of enamel formation, including Klk4, Mmp20, C4orf26, and Wdr72. Using a candidate gene approach we discovered a novel Wdr72 human mutation, resulting in a hypomaturation AI phenotype, to be a 5-base pair deletion (c.806_810delGGCAG; p.G255VfsX294). To gain insight into the function of WDR72, we used computer modeling of the full-length human WDR72 protein structure and found that the predicted N-terminal sequence forms two beta-propeller folds with an alpha-solenoid tail at the C-terminus. This domain iteration is characteristic of vesicle coat proteins, such as beta′-COP, suggesting a role for WDR72 in the formation of membrane

Though the major protein players have been identified and the high-resolution structure of enamel has been obtained, the process of its formation remains difficult to piece together because of its complexity, and is compounded by results from different laboratories that do not always reconcile well with each other. Multiple attempts to engineer artificial enamel have failed to reproduce the macromolecular interweaving structure of enamel rods or recapitulate the unique mechanical properties of natural enamel. A static in vitro method involving organic and inorganic molecular components lacks the dynamic variables that cells provide.. In order to produce enamel biomimetically, knowledge of the detailed mechanisms of amelogenesis are needed and would require cell lines with reproducible, predictable and physiologically-relevant properties. Addressing the lack of appropriate cell lines from presecretory to maturation stages would allow examination of essential molecular processes- such as ion and ...
Jalili syndrome is a genetic disorder characterized by the combination of cone-rod dystrophy of the retina and amelogenesis imperfecta. It was characterized in 1988 by Dr. I. K. Jalili and Dr. N. J. D. Smith, following the examination of 29 members of an inbred, Arab family living within the Gaza Strip. Affected individuals commonly suffer from photophobia, nystagmus and achromatopsia. Other symptoms affecting vision may include night vision difficulties; optic disc pallor; narrow vessels; macular atrophy with pigment mottling; peripheral deep white dot deposits or retinal pigment epithelium (RPE) alterations in the inferonasal retina; decreased foveal and retinal thickness; attenuation of retinal lamination; hyperreflectivity in the choroids (due to RPE and choriocapillaris atrophy); impairment of color vision; and progressive loss of vision with advancing age. In line with ameleogenesis imperfecta, affected members may display teeth yellow-brown in colour, dysplastic, presenting numerous ...

Binoomse või binaarse logistilise regressiooni puhul uuritakse olukorda, kus uuritaval tunnusel on kaks võimalikku väärtust: 0 ja 1. Multinominaalse regressiooni puhul on tegemist olukorraga, kus väljundiks on 3 või rohkem sõltumatut väärtust ning väärtustel puudub järjestus. Järjestatud logistilise regressiooni korral uuritakse tunnust, millel on mitu sõltuvat taset ning tasemed on järjestatud. Logit-mudel on kõige enam kasutatud meetod binaarse tunnuse modelleerimiseks.

Põlismetsale iseloomulike tunnuste arenemine on seotud suktsessiooniga, mille viimase staadiumi saavutamine nõuab aega. Vanade puude akumulatsioon hakkab mõjutama puistu struktuuri. Vanemad puistud arendavad häilusid kahel põhjusel. Esiteks, dominantsed puud hakkavad surema loodusliku vananemisprotsessi tagajärjel, mis muudab puud patogeenidele ja kahjuritele vastuvõtlikumaks. Kui sellised vanad puud on koondunud, tekitab see küllaltki suuri häile[12]. Teiseks, mida vanem on puistu, seda enam on tõenäoline, et selle struktuuri on mõjutanud häiringud.

Loss-of-function mutations in the Ca(2+) release-activated Ca(2+) channel genes ORAI1 and STIM1 abolish store-operated Ca(2+) entry (SOCE) and result in ectodermal dysplasia with amelogenesis imperfecta. However, because of the limited availability of patient tissue, analyses of enamel mineralization or possible changes in ameloblast function or morphology have not been possible. Here, we generated mice with ectodermal tissue-specific deletion of Stim1 ( Stim1 cKO [conditional knockout]), Stim2 ( Stim2 cKO), and Stim1 and Stim2 ( Stim1/2 cKO) and analyzed their enamel phenotypes as compared with those of control ( Stim1/2(fl/fl)) animals.

Connective Tissue Gene Tests offers five panel options for osteogenesis imperfecta (OI) testing utilizing NextGen sequencing technology, an OI COL1A1 & COL1A2 panel, an OI core panel, a dominant OI panel, a recessive OI panel and a combined dominant and recessive OI panel. In addition to genes associated with the autosomal dominant and autosomal recessive forms of OI, the panels also contain genes for disorders included in the differential diagnosis of OI. The Osteogenesis imperfecta core NGS panel consists of three genes: COL1A1, COL1A2 and IFITM5.. Copy number variation (CNV) analysis of the Osteogenesis imperfecta core genes is also offered as a panel. Additionally, CTGT offers a comprehensive test (both NGS and CNV panels) for these genes. Panel genes are also offered as individual sequencing and deletion/duplication tests unless otherwise indicated.. Osteogenesis imperfecta core panel. ...

Definition. Osteogenesis Imperfecta, also known as brittle bone disease, is a genetic disorder characterized by bones that break easily, often from little or no apparent cause. The term osteogenesis imperfecta means imperfect bone formation. Sometimes the bones of the affected person break for no known reason. At times bones break often from mild trauma or with no apparent cause. Multiple fractures are common, and in severe cases, can occur even before birth. Milder cases may involve only a few fractures over a persons lifetime. ...
Symptoms of osteogenesis imperfecta include short stature, weak muscles, and bones that fracture easily. This eMedTV Web page lists some of the potential osteogenesis imperfecta symptoms for each type of the disorder.
Osteogenesis imperfecta (OI) refers to a heterogeneous group of congenital, non-sex-linked, genetic disorders of collagen type I production, involving connective tissues and bones. The hallmark feature of osteogenesis imperfecta is osteoporosis...
As this eMedTV article explains, the cause of osteogenesis imperfecta is a defect in the genes responsible for producing collagen. This Web page further explores the cause of this condition and discusses the role of genetics.
Osteogenesis imperfecta (OI), also known as brittle bone disease, is a genetic disorder of connective tissue characterized by fragile bones...
Osteogenesis imperfecta (OI) is an inherited (genetic) bone disorder that is present at birth. It is also known as brittle bone disease. A child born with OI may have soft bones that break (fracture) easily, bones that are not formed normally, and other problems. Signs and symptoms may range from mild to severe.
In addition to a complete medical history and physical examination, diagnostic procedures for osteogenesis imperfecta may include a skin biopsy to evaluate the amount and structure of collagen. However, this test is complicated and not many qualified facilities are available to perform the procedure. It is not unusual for results of the biopsy to take up to six months.. Additional diagnostic tests may include:. ...

Jillian was born at 12:44pm, 2lbs 10oz, approx. 10 3/4 inches long. She was 7 1/2 weeks early as we kind of expected. Becky woke at 1:30am on Wednesday the 8th telling me that her water had broke. I rushed her to MTMC to confirm it and then we rushed off to Vanderbilt. On the way there Becky started having contractions. Once we got there they were able to slow them down until we decided how we were going to proceed with the delivery.. Jillian was diagnosed right before Christmas with a form of dwarfism called Osteogenesis Imperfecta, which is a condition in which the bones are less developed and easily broken. Some people can be born with this and live normal lives but sustaining frequent bone breaks, others not so lucky, and there are some that dont survive. Jillian was one of these cases. She was also not expected to make it to full term. There was no method of delivery we were told would make it easier or give her a better chance of survival. In the end Becky chose C-section, against the ...

Formålet med behandlingen er å hindre beinbrudd, sikre bevegeligheten i leddene og opprettholde en best mulig funksjonsevne. Fysioterapi, rehabilitering og ortopedisk kirurgi er de viktigste behandlingstiltakene ved osteogenesis imperfecta. Det finnes per i dag ingen helbredende behandling, men studier av nye medikamenter, stamcellebehandling og genterapi pågår - dog er ingen andre alternativer foreløpig aktuelle.. Det er viktig at barnet / personen prøver å være i så mye fysisk aktivitet som mulig uten å risikere beinbrudd. Det hindrer feilstillinger i leddene og minsker tapet av beinvev som gjør beinene enda skjørere.. Erfaring med såkalte bisfosfonater gitt direkte i blodet (eks. pamidronat, Aredia®)med jevne mellomrom, eller gitt som tabletter (eks. risedronat), har vist å ha en viss gunstig effekt. Preparatene motvirker beinskjørhet. De første gangene medikamentet blir gitt, kan det gi feberreaksjon. I Danmark anbefaler eksperter slik behandling hos barn og voksne med ...
