To test the hypothesis that children born to mothers living near the sea are at increased risk of limb reduction defects. Descriptive data analysis. The northern health region of England. All children born between 1 January 1985 and 31 December 1992 in the northern region of England with isolated limb reduction defects. The birth prevalence of isolated limb reduction defects was not affected by the distance the mother lived from the sea. There was some evidence of space-time clustering, but there was no evidence of statistically significant variation in the occurrence of the condition with sex, time of birth (monthly or yearly), or county of birth. There is no evidence that children born to mothers living near the sea are at increased risk of limb reduction defects.. ...

There are two types of limb difference - congenital and acquired ones.. Congenital limb difference. A number of different terms are used to describe children born with a congenital limb difference including Congenital Limb Reduction or Congenital Limb Deficiency. The term Dysmelia is also used as an umbrella term for all types of congenital limb differences. In the medical community congenital limb differences are considered to be rare.. There are many different causes of congenital limb differences. Some causes are genetic, some are due to environmental or pharmaceutical factors, whereas others may be because of an isolated issue or syndrome occurring during foetal development. Often there is no known cause for a congenital limb difference.. Some children born with a congenital limb difference may undergo reconstructive surgery to allow a prosthesis to be fitted.. ...

Glycosaminoglycans (GAGs) such as chondroitin are ubiquitous disaccharide carbohydrate chains that contribute to the formation and function of proteoglycans at the cell membrane and in the extracellular matrix. Although GAG-modifying enzymes are required for diverse cellular functions, the role of these proteins in human development and disease is less well understood. Here, we describe two sisters out of seven siblings affected by congenital limb malformation and malignant lymphoproliferative disease. Using Whole-Genome Sequencing (WGS), we identified in the proband deletion of a 55 kb region within chromosome 12q23 that encompasses part of CHST11 (encoding chondroitin-4-sulfotransferase 1) and an embedded microRNA (MIR3922). The deletion was homozygous in the proband but not in each of three unaffected siblings. Genotyping data from the 1000 Genomes Project suggest that deletions inclusive of both CHST11 and MIR3922 are rare events. Given that CHST11 deficiency causes severe chondrodysplasia in mice

The overall aim of this project is to study patients and parents experiences from healthcare interventions, the result of early fitting of myoelectric

Mutations in SALL1 and GLI3 are responsible for human limb malformation syndromes. The molecular pathophysiology of these mutations is incompletely understood, and many conclusions have been drawn from studies performed in the mouse. We identified truncating mutations in SALL1 and GLI3 in patients with limb malformation and studied the contribution of nonsense-mediated decay (NMD) to the expression of mutant mRNA in patient-derived fibroblasts. Quantification of the relative proportions of mutant and wild-type alleles was performed by pyrosequencing. In SALL1, a mutant allele causing Townes-Brocks syndrome was unexpectedly resistant to NMD, whereas a different mutation causing a much milder phenotype was susceptible to NMD. In GLI3, all three mutant alleles tested were susceptible to NMD. This work provides novel insights into the molecular pathophysiology of SALL1 and GLI3 mutations, extends the phenotypic spectrum of SALL1 mutations, and provides an example of a human mutation which does not follow

Eight sets of parents have filed suit against Pfizer Inc. over the antidepressant, Zoloft. Their lawsuit, filed last month in Illinois St. Clair County Circuit Court, claims Zoloft caused their children to be born with various birth defects including heart defects, neural tube defects, gastroschisis, omphalocele, craniosynostosis, cleft lip, club foot, anal atresia and limb reduction defects.. According to a report from the Madison-St. Clair Record, the mothers of the children named in the lawsuit all took Zoloft while pregnant. The lawsuit claims the mothers only took Zoloft because they believed it to be safe in pregnancy. The lawsuit alleges that Pfizer should have known that Zoloft crosses the placenta, which could have important implications for the developing fetus. Despite knowing of Zolofts pregnancy risks, Pfizer failed to warn the public. Even now, Pfizer continues to market Zoloft as a safe drug to take during pregnancy, the complaint alleges..

Many of you have known that we were adopting, but you may not be aware that Iris is special needs with bilateral upper limb deficiency. In simpler terms, she is missing her left arm completely at the shoulder and about half of her right arm, as you can see from the photo posted. She does have one finger, although we do not know the extent to which she can bend it or use it. She is healthy and normal otherwise, according to all of her medical and developmental reports. According to our pediatrician, Iriss upper limb deficiency is most likely due to amniotic banding in the womb. This is a condition that can occur very early in development in the womb where the fibrous bands of the amniotic sac constrict causing amputation or growth restriction of limbs or digits. When we bring Iris back home, she will receive treatment at Scottish Rite Childrens hospital for therapy and prostheses. Most children with congenital upper limb deficiencies actually end up not using prostheses because they are ...

In infants and children, amputations are frequently associated with congenital limb deficiencies, trauma, and tumors. Traumatic amputations in children in 2003 in the United States resulted in $22 million in inpatient costs for 946 cases. The majority of amputations were finger and thumb, but the highest costs were due to traumatic leg amputations. Congenital limb deficiencies are commonly described using the Birch revision of the Frantz and ORahilly classification system. Amelia is the complete absence of a limb; hemimelia is the absence of a major portion of a limb; and phocomelia is the attachment of the terminal limb at or near the trunk. Hemimelias can be further classified as terminal or intercalary. A terminal hemimelia is a complete transverse deficit at the end of the limb. An intercalary hemimelia is an internal segmental deficit with variable distal formation. In discussions of limb deficiencies, preaxial refers to the radial or tibial side of a limb, and postaxial refers to ...

Most cases of VACTERL association are sporadic, which means they occur in people with no history of the condition in their family. Rarely, families have multiple people affected with VACTERL association. A few affected individuals have family members with one or two features, but not enough signs to be diagnosed with the condition. In these families, the features of VACTERL association often do not have a clear pattern of inheritance. Multiple genetic and environmental factors likely play a part in determining the risk of developing this condition and how severe the condition will be in an individual. ...

In the most recent analysis of Swedish data on congenital malformations, it appeared that in the county of Östergötland, the prevalence of infants with a diagnosed congenital malformation was higher than in the rest of the country. This observation initiated an effort to make a more complete identification of all infants born with a congenital malformation in that county and to compare it with the other two counties in the Southeast region of Sweden (Jönköping and Kalmar), utilising all the relevant Swedish medical health registers available. A total of 10,171 infants with a congenital malformation of any type were identified in the region: 4,698 infants in Östergötland county (6.2%), and 5,473 in the reference counties (5.4%). A 15% excess malformation risk in Östergötland compared with the two reference counties. Various validations of the register data were undertaken and different types of error were detected. Limb reduction defects seemed to occur more often in Östergötland county ...

Prx1 and Prx2 are closely related paired-class homeobox genes that are expressed in very similar patterns predominantly in mesenchyme, Prx1 loss-of-function mutants show skeletal defects in skull, limbs and vertebral column (Martin, J, F,, Bradley, A, and Olson, E. N, (1995) Genes Dev. 9, 1237-1219). We report here that mice in which Prx2 is inactivated by a lacZ insertion had no skeletal defects, whereas Prx1/Prx2 double mutants showed many novel abnormalities in addition to an aggravation of the Prx1 single mutant phenotype. We found defects in external, middle and inner ear, reduction or loss of skull bones, a reduced and sometimes cleft mandible, and limb abnormalities including postaxial polydactyly and bent zeugopods, A single, or no incisor was present in the lower jaw, and ectopic expression of Fgf8 and Pax9 was found medially in the mandibular arch, A novel method to detect beta-galactosidase activity in hydroxyethylmethacrylate sections allowed detailed analysis of Prx2 expression in ...

Adams-Oliver syndrome (AOS) is characterized by terminal limb defects and congenital absence of skin on the scalp (aplasia cutis congenita). The limb defects most often affect the distal phalanges but more proximal defects have been observed. Defects include brachydactyly, syndactyly, hypoplastic fingers and toes, or even complete absence of fingers and toes. The limb defects may be asymmetrical. Cutis marmorata, dilated scalp veins, hypoplastic or absent nails, congenital heart defects, microphthalmia, microcephaly, and anomalies of the central nervous system have also been described. The clinical findings and penetrance of AOS are highly variable even within families.. The Adams-Oliver syndrome NGS panel consist of six genes: ARHGAP31, DLL4, DOCK6, EOGT, NOTCH1 and RBPJ..

The combination of vertebral defects, anal atresia, cardiac anomalies, tracheo-esophageal fistula, radial dysplasia and limb anomalies, and renal anomalies, termed VACTERL association, has been used as a clinical descriptor for a specific group of phenotypic manifestations that have been observed to occur together. Depending upon the diagnostic criteria used, the prevalence may be as high as 1 in 6000 live births. VACTERL association is felt to be due to defects in early embryogenesis, and is likely to be genetically heterogeneous. The purpose of the present study is to increase the understanding of the clinical manifestations and genetic causes of VACTERL association through detailed physical, laboratory, and radiological studies. We also plan to examine the spectrum of clinical characteristics in VACTERL association to facilitate early diagnosis and clinical management, including genetic counseling. To accomplish this, we plan to enroll approximately 25-50affected individuals along with their ...

A disorder characterized by the congenital absence of skin (aplasia cutis congenita) in combination with transverse limb defects. Aplasia cutis congenita can be located anywhere on the body, but in the vast majority of the cases, it is present on the posterior parietal region where it is often associated with an underlying defect of the parietal bones. Limb abnormalities are typically limb truncation defects affecting the distal phalanges or entire digits (true ectrodactyly). Only rarely, metatarsals/metacarpals or more proximal limb structures are also affected. Apart from transverse limb defects, syndactyly, most commonly of second and third toes, can also be observed. The clinical features are highly variable and can also include cardiovascular malformations, brain abnormalities and vascular defects such as cutis marmorata and dilated scalp veins ...

From 2001 to 2004, 12 patients with VACTERL association who were treated operatively by a single pediatric surgeon underwent magnetic resonance (MR) imaging to evaluate the intraspinal abnormalities that may cause tethering. Three patients were excluded from the study due to complications after surgery for TEF. Coincidentally, these three patients did ...

The VACTERL association (also VATER association, and less accurately VACTERL syndrome) refers to a recognized group of birth defects which tend to co-occur (see below). Note that this pattern is a recognized association, as opposed to a syndrome, because there is no known pathogenetic cause to explain the grouped incidence. Each child with this condition can be unique. At present this condition is treated after birth with issues being approached one at a time. Some infants are born with symptoms that cannot be treated and they do not survive. Also, VACTERL association can be linked to other similar conditions such as Klippel Feil and Goldenhar Syndrome including crossovers of conditions. No specific genetic or chromosome problem has been identified with VACTERL association. VACTERL can be seen with some chromosomal defects such as Trisomy 18 and is more frequently seen in babies of diabetic mothers. VACTERL association, however, is most likely caused by multiple factors.[1] VACTERL association ...

NIH Rare Diseases : 50 robinow syndrome is a rare disorder that affects the bones as well as other parts of the body. two forms of robinow syndrome have been described: autosomal recessive robinow syndrome, and the milder autosomal dominant robinow syndrome. they are distinguished based on their modes of inheritance, symptoms, and severity. autosomal recessive robinow syndrome causes shortening of the long bones in the arms and legs; short fingers and toes; wedge-shaped spinal bones leading to kyphoscoliosis; fused or missing ribs; short stature; and distinctive facial features. other features may include underdeveloped genitalia; dental problems; kidney or heart defects; or delayed development. this form is caused by mutations in the ror2 gene.autosomal dominant robinow syndrome causes more mild, but similar, features. there are rarely spine and rib abnormalities, and short stature is less severe. a variant type of this form is additionally characterized by osteosclerosis. autosomal dominant ...

The congenital malformation split hand/foot (SHFM) is characterized by missing central fingers and dysmorphology or fusion of the remaining ones. Type-1 SHFM is linked to deletions/rearrangements of the DLX5-DLX6 locus and point mutations in the DLX5 gene. The ectrodactyly phenotype is reproduced in mice by the double knockout (DKO) of Dlx5 and Dlx6. During limb development, the apical ectodermal ridge (AER) is a key-signaling center responsible for early proximal-distal growth and patterning. In Dlx5;6 DKO hindlimbs, the central wedge of the AER loses multilayered organization and shows down-regulation of FGF8 and Dlx2. In search for the mechanism, we examined the non-canonical Wnt signaling, considering that Dwnt-5 is a target of distalless in Drosophila and the knockout of Wnt5, Ryk, Ror2 and Vangl2 in the mouse causes severe limb malformations. We found that in Dlx5;6 DKO limbs, the AER expresses lower levels of Wnt5a, shows scattered β-catenin responsive cells and altered basolateral and ...

In 1991 the Medical Research Council Vitamin Study Group and in 1992 the Hungarian randomised clinical trial have shown conclusively that the risk of neural tube defects can be reduced substantially by taking folic acid during the peri-conceptional period. At present there is enough evidence to support the hypothesis that folic acid supplementation can reduce the risk of all congenital malformations or of a specific and selected group of them, namely: neural tube defects, oral clefts, cardiac defects, urinary tract anomalies except hypospadias, limb reduction defects, omphalocele, anal atresia and trisomy 21.. The hypothesis that a higher intake of folic acid is related to an higher risk reduction of neural tube defects and of other congenital malformations is the main rationale for the present study.. The present study is a randomized, double-blind, controlled trial evaluating whether supplementation with folic acid at high dose (4 mg/day) reduces the overall risk of major congenital ...

Absence of an extremity or a segment of an extremity is referred to as limb deficiency or congenital amputation. The prevalence of limb reduction deformities is about 1 per 20,000 births. In about 50% of cases, there are multiple reduction deficiencies, and in 25% of these, there are additional anomalies of the body structures. Isolated amputation of an extremity can be due to amniotic band syndrome, exposure to a teratogen or a vascular accident. Acheiria related with misoprostol use in pregnancy for gastric complaints has been defined in the literature. There is also an association between chorion villous sampling before 10 weeks of gestation and transverse limb defects. Isolated limb reduction deformities, such as amelia (complete absence of extremities), acheiria (absence of the hand), phocomelia (seal limb) or aplasia-hypoplasia of the radius or ulna often forms the part of a genetic syndrome (such as Holt-Oram syndrome, Fanconi pancytopenia, thrombocytopenia with absent radii ...

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes the homolog of the Drosophila melanogaster Nipped-B gene product and fungal Scc2-type sister chromatid cohesion proteins. The Drosophila protein facilitates enhancer-promoter communication of remote enhancers and plays a role in developmental regulation. It is also homologous to a family of chromosomal adherins with broad roles in sister chromatid cohesion, chromosome condensation, and DNA repair. The human protein has a bipartite nuclear targeting sequence and a putative HEAT repeat. Condensins, cohesins and other complexes with chromosome-related functions also contain HEAT repeats. Mutations in this gene result in Cornelia de Lange syndrome, a disorder characterized by dysmorphic facial features, growth delay, limb reduction defects, and mental retardation. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008 ...

Locomotor training using equipment that helps to support a patients body weight is helping some patients with spinal cord injuries improve or gain walking ability. Studies conducted involving people with both acute and chronic SCI (spinal cord injury) have shown that it can be possible for patients with motor-incomplete paraplegia or tetraplegia, who still have some feeling or ability to move after their injury, to improve their ability to walk with body-weight-supported training on a treadmill. Shriners Hospitals in Philadelphia and Chicago offer this therapy technique, which provides tremendous therapeutic opportunities to their patients with SCI, as well as those with other conditions that affect walking, such as limb deficiencies, cerebral palsy and arthrogryposis.. Shriners Hospitals for Children is a health care system with 22 locations in the U.S., Canada and Mexico. Its staff is dedicated to improving the lives of children by providing pediatric specialty care, conducting innovative ...

The HoxD cluster is critical for vertebrate limb development. Enhancers located in both the telomeric and centromeric gene deserts flanking the cluster regulate the transcription of HoxD genes. In rare patients, duplications, balanced translocations or inversions misregulating HOXD genes are responsible for mesomelic dysplasia of the upper and lower limbs. By aCGH, whole-genome mate-pair sequencing, long-range PCR and fiber fluorescent in situ hybridization, we studied patients from two families displaying mesomelic dysplasia limited to the upper limbs. We identified microduplications including the HOXD cluster and showed that microduplications were in an inverted orientation and inserted between the HOXD cluster and the telomeric enhancers. Our results highlight the existence of an autosomal dominant condition consisting of isolated ulnar dysplasia caused by microduplications inserted between the HOXD cluster and the telomeric enhancers. The duplications likely disconnect the HOXD9 to HOXD11 genes from

N2 - Retinoic acid (RA) can induce growth arrest and neuronal differentiation of neuroblastoma cells and has been used in clinic for treatment of neuroblastoma. It has been reported that RA induces the expression of several HOXD genes in human neuroblastoma cell lines, but their roles in RA action are largely unknown. The HOXD cluster contains nine genes (HOXD1, HOXD3, HOXD4, and HOXD8-13) that are positioned sequentially from 3′ to 5′, with HOXD1 at the 3′ end and HOXD13 the 5′ end. Here we show that all HOXD genes are induced by RA in the human neuroblastoma BE(2)-C cells, with the genes located at the 3′ end being activated generally earlier than those positioned more ...

Researchers suspect that 30 to 50 percent of all cases of Russell-Silver syndrome result from changes in a process called methylation on the short (p) arm of chromosome 11 at position 15 (11p15). Methylation is a chemical reaction that attaches small molecules called methyl groups to certain segments of DNA ...

Close up of the deformed hand and forearm of a thalidomide baby. Thalidomide is a sedative drug which was introduced in Britain and Germany in the early 1960s.

Sherri Finkbine was the cute, perky, respectable Romper Room lady who went to Sweden, amid great fanfare, to snuff the fetus that she had injured by taking Thalidomide while she was pregnant. She did probably more than anybody else to normalize abortion and make it palatable to the public, and to promote the idea that its somehow nice to treat people with limb deformities, and other folks who dont fit our ideas of perfection, as if theyre disposable. So much for tolerance and diversity ...
