Cleidocranial dysplasia (CCD) is an autosomal dominant skeletal dysplasia. Affected individuals have hypoplastic/aplastic clavicles and multiple dental abnormalities.
Cleidocranial dysplasia (CCD) is a autosomal dominant disorder characterized by skeletal anomalies such as patent fontanels, late closure of cranial sutures with Wormian bones, late erupting secondary dentition, rudimentary clavicles, and short stature. The locus for this disease was mapped to chrom …
Mutations in human and/or mouse homologs are associated with this disease. Synonyms: cleidocranial dysplasia with micrognathia, absent thumbs, and distal aphalangia; cleidocranial dysplasia-micrognathia-absent thumbs syndrome
The Caenorhabditis elegans run gene encodes a Runt domain factor. Runx1, Runx2, and Runx3 are the three known mammalian homologs of run. Runx1, which plays an essential role in hematopoiesis, has been identified at the breakpoint of chromosome translocations that are responsible for human leukemia. Runx2 plays an essential role in osteogenesis, and inactivation of one allele of Runx2 is responsible for the human disease cleidocranial dysplasia. To understand the role of run in C. elegans, we used transgenic run::GFP reporter constructs and a double-stranded RNA-mediated interference method. The expression of run was detected as early as the bean stage exclusively in the nuclei of seam hypodermal cells and lasted until the L3 stage. At the larval stage, expression of run was additionally detected in intestinal cells. The regulatory elements responsible for the postembryonic hypodermal seam cells and intestinal cells were separately located within a 7.2-kb-long intron region. This is the first ...
Human diseases caused by defects of the primary cilium (ciliopathies) are a group of distinct disorders with overlapping features. Clinical features of ciliopathies include fibrocystic disease of the kidneys and liver, retinal degeneration, obesity, structural and functional defects of the central nervous system and the eyes, abnormal bone growth, abnormal sidedness of internal organs and polydactyly. Human ciliopathies characterized by variable combinations of these features include autosomal recessive (ARPKD) and dominant (ADPKD) polycystic kidney diseases, nephronophthisis (NPHP), Joubert syndrome and related disorders (JSRD), Bardet-Biedl (BBS), Meckel-Gruber (MKS), Oral-Facial-Digital-type 1 (OFD1), and Alstrom syndromes (AS) and skeletal disorders such as Jeune syndrome (JS) and cleidocranial dysplasia. ARPKD, the most common pediatric ciliopathy, is characterized by cystic degeneration of the kidneys and congenital hepatic fibrosis of the liver. JSRD are a heterogenous group of syndromes ...

Mutations in several genes in Table 3 have been associated with diseases affecting cognitive capacities. DYRK1A, which lies in the Down syndrome critical region, is thought to underlie some of the cognitive impairment associated with having three copies of chromsome 21 (64). Mutations in NRG3 have been associated with schizophrenia, a condition that has been suggested to affect human-specific cognitive traits (65, 66). Mutations in CADPS2 have been implicated in autism (67), as have mutations in AUTS2 (68). Autism is a developmental disorder of brain function in which social interactions, communication, activity, and interest patterns are affected, as well as cognitive aspects crucial for human sociality and culture (69). It may thus be that multiple genes involved in cognitive development were positively selected during the early history of modern humans.. One gene of interest may be RUNX2 (CBFA1). It is the only gene in the genome known to cause cleidocranial dysplasia, which is characterized ...

Homopolymeric amino acids repeats (AARs), which are widespread in proteomes, have often been viewed simply as spacers between protein domains, or even as junk sequences with no obvious function but with a potential to cause harm upon expansion as in genetic diseases associated with polyglutamine or polyalanine expansions, including Huntington disease and cleidocranial dysplasia. A growing body of evidence indicates however that at least some AARs can form organized, functional protein structures and can regulate protein function. In particular, certain AARs can mediate protein-protein interactions, either through homotypic AAR-AAR contacts or through heterotypic contacts with other protein domains. It is still unclear however, whether AARs may have a generalized, proteome-wide role in shaping protein-protein interaction networks. Therefore, we have undertaken here a bioinformatics screening of the human proteome and interactome in search of quantitative evidence of such a role. We first identified the

TY - JOUR. T1 - Correlation between genotype and supernumerary tooth formation in cleidocranial dysplasia. AU - Suda, N.. AU - Hattori, M.. AU - Kosaki, Kenjiro. AU - Banshodani, A.. AU - Kozai, K.. AU - Tanimoto, K.. AU - Moriyama, K.. PY - 2010/11. Y1 - 2010/11. N2 - Introduction - Cleidocranial dysplasia (CCD, MIM#119600), for which the responsible gene is RUNX2, is a genetic disorder characterized by hypoplasia or aplasia of the clavicles, patent fontaneles, and a short stature. Supernumerary teeth and delayed eruption and impaction of permanent teeth are frequently associated with CCD. Our previous study reported wide intrafamilial variation in supernumerary tooth formation associated with a mutation in the RUNT-domain of RUNX2, suggesting a low correlation between the genotype and supernumerary tooth formation. To further clarify this point, a more precise evaluation was performed. Design - Gene mutational analysis of nine Japanese individuals with CCD was performed. Dental and skeletal ...

The peg-shaped conical tooth is the supernumerary tooth most commonly found in the permanent dentition. It develops with root formation ahead of or at an equivalent stage to that of the permanent incisors and usually presents as a mesiodens.1. Tooth malformations such as conical incisors and conical canines are commonly seen in hypohidrotic ectodermal dysplasia males and may also occur in heterozygous females to a less severe degree.2. Wormian bones are small bones that are often found within the sutures and fontanelles of the skull. They are often considered to be a simple anatomical variation. Nonetheless, they are more commonly seen in patients with certain kinds of bone dysplasia such as cleidocranial dysostosis, pycnodysostosis, congenital hypothyroidism, rickets and osteogenesis imperfecta. These bones are very common and sometimes occur in high numbers in children even when there is no history of osteogenesis imperfecta, and they are usually considered to be a simple anatomical variant ...

RUNX2 is an essential transcription factor required for skeletal development and cartilage formation. Haploinsufficiency of RUNX2 leads to cleidocranial displaysia (CCD) a skeletal disorder characterised by gross dysgenesis of bones particularly those derived from intramembranous bone formation. A notable feature of the RUNX2 protein is the polyglutamine and polyalanine (23Q/17A) domain coded by a repeat sequence. Since none of the known mutations causing CCD characterised to date map in the glutamine repeat region, we hypothesised that Q-repeat mutations may be related to a more subtle bone phenotype. We screened subjects derived from four normal populations for Q-repeat variants. A total of 22 subjects were identified who were heterozygous for a wild type allele and a Q-repeat variant allele: (15Q, 16Q, 18Q and 30Q). Although not every subject had data for all measures, Q-repeat variants had a significant deficit in BMD with an average decrease of 0.7SD measured over 12 BMD-related parameters ...
Osteochondrodysplasia or skeletal dysplasia is a general term for a disorder of the development (dysplasia) of bone ("osteo") and cartilage ("chondro"). Osteochondrodysplasias are rare diseases. About 1 in 5,000 babies are born with some type of skeletal dysplasia. Achondroplasia is a type of autosomal dominant genetic disorder that is the most common cause of dwarfism. Achondroplastic dwarfs have short stature, with an average adult height of 131 cm (4 feet, 3 inches) for males and 123 cm (4 feet, 0 inches) for females. The prevalence is approximately 1 in 25,000 births. Cleidocranial dysostosis is a general skeletal condition named for the collarbone (cleido-) and cranium deformities which people with it often have. Common features include: Partly or completely missing collarbones. A soft spot or larger soft area in the top of the head where the fontanelle failed to close. Bones and joints are underdeveloped. The permanent teeth include supernumerary teeth. Permanent teeth not erupting Bossing ...
TRPV4 related skeletal disorders - Heterozygous mutations in the transient receptor potential cation channel, subfamily V, member 4 gene (TRPV4) have been shown to be responsible for spondyloepiphyseal dysplasia, Maroteaux type (MIM 184095), brachyolmia type 3 (MIM 113500), spondylometaphyseal dysplasia, Kozlowski type (SMDK; MIM 184252), metatropic dysplasia (MIM 156530), parastremmatic dwarfism (MIM 168400), and digital arthropathy-brachydactyly, familial (FDAB; MIM 606835). This gene encodes a channel molecule involved in calcium ion homeostasis.. Spondyloepiphyseal dysplasia, Maroteaux type, also known as pseudo-Morquio syndrome, type 2 is an autosomal dominant skeletal dysplasia. Affected individuals have a normal birth weight and length but display progressive shortening of the trunk resulting in extreme short stature. Additional findings include platyspondyly, brachydactyly, genu valgum, cubitus valgus, broad pelvis, enlarged joints and dysplastic changes of the femoral neck.. Brachyolmia ...
Tooth agenesis is one of predominant developmental anomalies in humans, usually affecting the permanent dentition generated by sequential tooth formation, and in most cases caused by mutations perturbing epithelial Wnt/β-catenin signaling. Also loss-of-function mutations in the Wnt feedback inhibitor AXIN2 lead to human tooth agenesis. We investigated the functions of Wnt/β-catenin signaling during sequential formation of molar teeth using mouse models. Continuous initiation of new teeth, observed after genetic activation of Wnt/β-catenin signaling in the oral epithelium, was accompanied by enhanced expression of Wnt antagonists and a downregulation of Wnt/β-catenin signaling in the dental mesenchyme. Genetic and pharmacological activation of mesenchymal Wnt/β-catenin signaling negatively regulated sequential tooth formation, an effect partly mediated by Bmp4. Runx2, a gene whose loss-of-function mutations result in sequential formation of supernumerary teeth in the human cleidocranial ...
The lipid phosphatase FIG4 is a subunit of the protein complex that regulates biosynthesis of the signaling lipid PI(3,5)P2. Mutations of FIG4 result in juvenile lethality and spongiform neurodegeneration in the mouse, and are responsible for the human disorders Charcot-Marie-Tooth disease, Yunis-Varon syndrome and polymicrogyria with seizures.
The endolysosomal system and autophagy are essential components of macromolecular turnover in eukaryotic cells. The low-abundance signaling lipid PI(3,5)P2 is a key regulator of this pathway. Analysis of mouse models with defects in PI(3,5)P2 biosynthesis has revealed the unique dependence of the mammalian nervous system on this signaling pathway. This insight led to the discovery of the molecular basis for several human neurological disorders, including Charcot-Marie-Tooth disease and Yunis-Varon syndrome. Spontaneous mutants, conditional knockouts, transgenic lines, and gene-trap alleles of Fig4, Vac14, and Pikfyve (Fab1) in the mouse have provided novel information regarding the role of PI(3,5)P2in vivo. This review summarizes what has been learned from mouse models and highlights the utility of manipulating complex signaling pathways in vivo.

TY - JOUR. T1 - Uremia induces the osteoblast differentiation factor Cbfa1 in human blood vessels. AU - Moe, Sharon. AU - Duan, Danxia. AU - Doehle, Brian P.. AU - ONeill, Kalisha D.. AU - Chen, Xuening (Neal). PY - 2003/3/1. Y1 - 2003/3/1. N2 - Background. Bone matrix proteins are expressed in calcified arteries from dialysis patients, suggesting that vascular smooth muscle cells (VSMCs) may transform to osteoblast-like cells. One of the key transcriptional regulators of osteoblast differentiation is Cbfa1. Thus, we hypothesized that this may be a key factor in arterial calcification. Methods. To test this hypothesis, we examined sections of the inferior epigastric artery from uremic patients for the presence of Cbfa1 and type I collagen and osteopontin by in situ hybridization and immunostaining. We also examined the effect of pooled uremic sera from dialysis patients on the expression of Cbfa1 by reverse transcription-polymerase chain reaction (RT-PCR) in bovine VSMCs in vitro. Results. ...
