Genomic imprinting: implications for human disease. (1/164)

Genomic imprinting refers to an epigenetic marking of genes that results in monoallelic expression. This parent-of-origin dependent phenomenon is a notable exception to the laws of Mendelian genetics. Imprinted genes are intricately involved in fetal and behavioral development. Consequently, abnormal expression of these genes results in numerous human genetic disorders including carcinogenesis. This paper reviews genomic imprinting and its role in human disease. Additional information about imprinted genes can be found on the Genomic Imprinting Website at http://www.geneimprint.com.  (+info)

Loss of imprinting of a paternally expressed transcript, with antisense orientation to KVLQT1, occurs frequently in Beckwith-Wiedemann syndrome and is independent of insulin-like growth factor II imprinting. (2/164)

Genomic imprinting plays a fundamental role in cancer and some hereditary diseases, including Beckwith-Wiedemann syndrome (BWS), a disorder of prenatal overgrowth and predisposition to embryonal malignancies such as Wilms tumor. We have previously shown that the KVLQT1 gene on chromosomal band 11p15 is imprinted, with expression of the maternal allele, and that the maternal allele is disrupted in rare BWS patients with balanced germ-line chromosomal rearrangements. We now show that an antisense orientation transcript within KVLQT1, termed LIT1 (long QT intronic transcript 1) is expressed normally from the paternal allele, from which KVLQT1 transcription is silent, and that in the majority of patients with BWS, LIT1 is abnormally expressed from both the paternal and maternal alleles. Eight of sixteen informative BWS patients (50%) showed biallelic expression, i.e., loss of imprinting (LOI) of LIT1. Similarly, 21 of 36 (58%) BWS patients showed loss of maternal allele-specific methylation of a CpG island upstream of LIT1. Surprisingly, LOI of LIT1 was not linked to LOI of insulin-like growth factor II (IGF2), which was found in 2 of 10 (20%) BWS patients, even though LOI of IGF2 occurs frequently in Wilms and other tumors, and in some patients with BWS. Thus, LOI of LIT1 is the most common genetic alteration in BWS. We propose that 11p15 harbors two imprinted gene domains-a more centromeric domain including KVLQT1 and p57(KIP2), alterations in which are more common in BWS, and a more telomeric domain including IGF2, alterations in which are more common in cancer.  (+info)

Anesthetic considerations of two sisters with Beckwith-Wiedemann syndrome. (3/164)

Anesthetic considerations of 21-mo-old and 4-yr-old sisters with Beckwith-Wiedemann syndrome during surgical repair of cleft palate and reduction of macroglossia are presented and discussed. This syndrome is characterized by exomphalos, macroglossia, gigantism, hypoglycemia in infancy, and many other clinical features. This syndrome is also known as exomphalos, macroglossia, and gigantism (EMG) syndrome. Principal problems associated with anesthetic management in this syndrome are hypoglycemia and macroglossia. Careful intraoperative plasma glucose monitoring is particularly important to prevent the neurologic sequelae of unrecognized hypoglycemia. It is expected that airway management would be complicated by the macroglossia, which might cause difficult bag/mask ventilation and endotracheal intubation following the induction of anesthesia and muscle paralysis, so preparations for airway difficulty (e.g., awake vocal cord inspection) should be considered before induction. A nasopharyngeal airway is useful in relieving postoperative airway obstruction.  (+info)

LIT1, an imprinted antisense RNA in the human KvLQT1 locus identified by screening for differentially expressed transcripts using monochromosomal hybrids. (4/164)

Mammalian imprinted genes are frequently arranged in clusters on particular chromosomes. The imprinting cluster on human chromosome 11p15 is associated with Beckwith-Wiedemann syndrome (BWS) and a variety of human cancers. To clarify the genomic organization of the imprinted cluster, an extensive screen for differentially expressed transcripts in the 11p15 region was performed using monochromosomal hybrids with a paternal or maternal human chromosome 11. Here we describe an imprinted antisense transcript identified within the KvLQT1 locus, which is associated with multiple balanced chromosomal rearrangements in BWS and an additional breakpoint in embryonal rhabdoid tumors. The transcript, called LIT1 (long QT intronic transcript 1), was expressed preferentially from the paternal allele and produced in most human tissues. Methylation analysis revealed that an intronic CpG island was specifically methylated on the silent maternal allele and that four of 13 BWS patients showed complete loss of maternal methylation at the CpG island, suggesting that antisense regulation is involved in the development of human disease. In addition, we found that eight of eight Wilms' tumors exhibited normal imprinting of LIT1 and five of five tumors displayed normal differential methylation at the intronic CpG island. This contrasts with five of six tumors showing loss of imprinting of IGF2. We conclude that the imprinted gene domain at the KvLQT1 locus is discordantly regulated in cancer from the imprinted domain at the IGF2 locus. Thus, this positional approach using human monochromosomal hybrids could contribute to the efficient identification of imprinted loci in humans.  (+info)

A maternally methylated CpG island in KvLQT1 is associated with an antisense paternal transcript and loss of imprinting in Beckwith-Wiedemann syndrome. (5/164)

Loss of imprinting at IGF2, generally through an H19-independent mechanism, is associated with a large percentage of patients with the overgrowth and cancer predisposition condition Beckwith-Wiedemann syndrome (BWS). Imprinting control elements are proposed to exist within the KvLQT1 locus, because multiple BWS-associated chromosome rearrangements disrupt this gene. We have identified an evolutionarily conserved, maternally methylated CpG island (KvDMR1) in an intron of the KvLQT1 gene. Among 12 cases of BWS with normal H19 methylation, 5 showed demethylation of KvDMR1 in fibroblast or lymphocyte DNA; whereas, in 4 cases of BWS with H19 hypermethylation, methylation at KvDMRl was normal. Thus, inactivation of H19 and hypomethylation at KvDMR1 (or an associated phenomenon) represent distinct epigenetic anomalies associated with biallelic expression of IGF2. Reverse transcription-PCR analysis of the human and syntenic mouse loci identified the presence of a KvDMR1-associated RNA transcribed exclusively from the paternal allele and in the opposite orientation with respect to the maternally expressed KvLQT1 gene. We propose that KvDMR1 and/or its associated antisense RNA (KvLQT1-AS) represents an additional imprinting control element or center in the human 11p15.5 and mouse distal 7 imprinted domains.  (+info)

Glypican-3-deficient mice exhibit developmental overgrowth and some of the abnormalities typical of Simpson-Golabi-Behmel syndrome. (6/164)

Glypicans are a family of heparan sulfate proteoglycans that are linked to the cell surface through a glycosyl-phosphatidylinositol anchor. One member of this family, glypican-3 (Gpc3), is mutated in patients with the Simpson-Golabi-Behmel syndrome (SGBS). These patients display pre- and postnatal overgrowth, and a varying range of dysmorphisms. The clinical features of SGBS are very similar to the more extensively studied Beckwith-Wiedemann syndrome (BWS). Since BWS has been associated with biallelic expression of insulin-like growth factor II (IGF-II), it has been proposed that GPC3 is a negative regulator of IGF-II. However, there is still no biochemical evidence indicating that GPC3 plays such a role.Here, we report that GPC3-deficient mice exhibit several of the clinical features observed in SGBS patients, including developmental overgrowth, perinatal death, cystic and dyplastic kidneys, and abnormal lung development. A proportion of the mutant mice also display mandibular hypoplasia and an imperforate vagina. In the particular case of the kidney, we demonstrate that there is an early and persistent developmental abnormality of the ureteric bud/collecting system due to increased proliferation of cells in this tissue element. The degree of developmental overgrowth of the GPC3-deficient mice is similar to that of mice deficient in IGF receptor type 2 (IGF2R), a well characterized negative regulator of IGF-II. Unlike the IGF2R-deficient mice, however, the levels of IGF-II in GPC3 knockouts are similar to those of the normal littermates.  (+info)

Analysis of germline CDKN1C (p57KIP2) mutations in familial and sporadic Beckwith-Wiedemann syndrome (BWS) provides a novel genotype-phenotype correlation. (7/164)

Beckwith-Wiedemann syndrome (BWS) is a human imprinting disorder with a variable phenotype. The major features are anterior abdominal wall defects including exomphalos (omphalocele), pre- and postnatal overgrowth, and macroglossia. Additional less frequent complications include specific developmental defects and a predisposition to embryonal tumours. BWS is genetically heterogeneous and epigenetic changes in the IGF2/H19 genes resulting in overexpression of IGF2 have been implicated in many cases. Recently germline mutations in the cyclin dependent kinase inhibitor gene CDKN1C (p57KIP2) have been reported in a variable minority of BWS patients. We have investigated a large series of familial and sporadic BWS patients for evidence of CDKN1C mutations by direct gene sequencing. A total of 70 patients with classical BWS were investigated; 54 were sporadic with no evidence of UPD and 16 were familial from seven kindreds. Novel germline CDKN1C mutations were identified in five probands, 3/7 (43%) familial cases and 2/54 (4%) sporadic cases. There was no association between germline CDKN1C mutations and IGF2 or H19 epigenotype abnormalities. The clinical phenotype of 13 BWS patients with germline CDKN1C mutations was compared to that of BWS patients with other defined types of molecular pathology. This showed a significantly higher frequency of exomphalos in the CDKN1C mutation cases (11/13) than in patients with an imprinting centre defect (associated with biallelic IGF2 expression and H19 silencing) (0/5, p<0.005) or patients with uniparental disomy (0/9, p<0.005). However, there was no association between germline CDKN1C mutations and risk of embryonal tumours. No CDKN1C mutations were identified in six non-BWS patients with overgrowth and Wilms tumour. These findings (1) show that germline CDKN1C mutations are a frequent cause of familial but not sporadic BWS, (2) suggest that CDKN1C mutations probably cause BWS independently of changes in IGF2/H19 imprinting, (3) provide evidence that aspects of the BWS phenotype may be correlated with the involvement of specific imprinted genes, and (4) link genotype-phenotype relationships in BWS and the results of murine experimental models of BWS.  (+info)

CDKN1C expression in Beckwith-Wiedemann syndrome patients with allele imbalance. (8/164)

In this study, we have examined CDKN1C expression in BWS patients with allele imbalance (AI) affecting the 11p15 region. Two of two informative patients with AI, attributable to mosaic paternal isodisomy, exhibited reduced levels of CDKN1C expression in the liver and kidney, respectively, relative to expression levels in the equivalent tissues in normal controls. Although overall expression was reduced, some expression from the paternally derived CDKN1C allele was evident, consistent with incomplete paternal imprinting of the gene. One patient showed evidence of maternal allele silencing in addition to AI. These findings show for the first time that CDKN1C expression is reduced in BWS patients with AI and suggest that CDKN1C haploinsufficiency contributes to the BWS phenotype in patients with mosaic paternal isodisomies of chromosome 11.  (+info)

Beckwith-Wiedemann syndromeDefinitionBeckwith-Wiedemann syndrome (BWS) refers to a disorder of overgrowth. This condition is usually characterized by large body size (macrosomia), large tongue (macroglossia), enlarged internal organs (visceromegaly), the presence of an abdominal wall defect (umbilical hernia or omphalocele ), and low blood sugar in the newborn period (neonatal hypoglycemia). Source for information on Beckwith-Wiedemann Syndrome: Gale Encyclopedia of Genetic Disorders dictionary.
Beckwith-Wiedemann syndrome (BWS) is a well-studied human overgrowth disorder, associated with visceromegaly, exomphalos, and predisposition to Wilms tumor and other pediatric cancers. BWS is a clinical syndrome, not a single disorder. Phenotypic heterogeneity is prominent, and we now appreciate that this reflects an underlying molecular heterogeneity. The syndrome can be caused by various molecular defects, which lead to altered expression of certain imprinted genes on chromosome 11p15. Multiple studies have revealed striking epigenotype-phenotype correlations, in which exomphalos tracks with one type of imprinting defect, affecting the CDKN1C gene, while Wilms tumor predisposition tracks with a different imprinting defect, affecting the IGF2 and H19 genes. Here we review the clinical and molecular features of BWS and summarize the data from these recent investigations. We also review the fascinating association of BWS with twinning, and discuss preliminary studies suggesting an increased ...

We report on an 8-month-old girl with a novel unbalanced chromosomal rearrangement, consisting of a terminal deletion of 4p and a paternal duplication of terminal 11p. Each of these is associated with the well-known clinical phenotypes of Wolf-Hirschhorn syndrome (WHS) and Beckwith-Wiedemann syndrome (BWS), respectively. She presented for clinical evaluation of dysmorphic facial features, developmental delay, atrial septal defect (ASD), and left hydro-nephrosis. High-resolution cytogenetic analysis revealed a normal female karyotype, but subtelomeric fluorescence in situ hybridization (FISH) analysis revealed a der(4)t(4;11) (pter;pter). Both FISH and microarray CGH studies clearly demonstrated that the WHS critical regions 1 and 2 were deleted, and that the BWS imprinted domains (ID) 1 and 2 were duplicated on the der(4). Parental chromosome analysis revealed that the father carried a cryptic balanced t(4;11)(pter;pter). As expected, our patient manifests findings of both WHS (a growth ...

IVF linked to rare genetic disorders. Dr. Weksberg who is a geneticist at the University of Toronto, has called for more study of the link between fertility treatment and certain rare genetic abnormalities. She notes that babies, who are born after this treatment, are 10 times more likely to suffer from these disorders. These babies also have an increased likelihood to be born at a low birth weight, and there is conflicting research suggesting an increased risk of autism. She says that in her genetic clinic, she is seeing many people who were conceived through fertility treatment and who have one of the conditions.. For example, Beckwith-Wiedemann syndrome can cause unevenly sized limbs, an enlarger tongue, and a high risk of kidney tumors. It occurs in one of every 13,000 children in the general population, but at a much higher rate of one in 1,300 in children conceived through IVF. Similarly, Angelman syndrome which causes serious mental retardation and speech impairment, increases from one in ...

The Beckwith-Wiedemann syndrome, originally described by Beckwith in 1963 and Wiedemann in 1964, included congenital anomalies such as macroglossia, exomphalos, postnatal somatic gigantism, severe hypoglycemia, abdominal wall defect, capillary nevus flameus and hemihypertrophy. Macroglossia is the most common manifestation of Beckwith-Wiedemann syndrome, with studies reporting between 82 and 95 percent of the cases. Macroglossia may cause the upper airway obstruction, deglutition difficulty, articulation interference and protrusion of dentoalveloar structures resulting in anterior open bite and a mandibular prognathism. We experienced a 5 month-old male with upper airway obstruction, deglutition difficulty and recurrent upper airway infection due to macroglossia associated with Beckwith-Wiedemann syndrome and significant improvement in respiration, feeding and oral competence at 14 months follow-up after rhomboid resection and primary closure of tongue. ...
Beckwith-Wiedemann syndrome (BWS) is a growth disorder variably characterized by neonatal hypoglycemia, macrosomia, macroglossia, hemihyperplasia, omphalocele, embryonal tumors (e.g., Wilms tumor, hepatoblastoma, neuroblastoma, and rhabdomyosarcoma), visceromegaly, adrenocortical cytomegaly, renal abnormalities (e.g., medullary dysplasia, nephrocalcinosis, medullary sponge kidney, and nephromegaly), and ear creases/pits. BWS is considered a clinical spectrum, in which affected individuals may have many of these features or may have only one or two clinical features. Early death may occur from complications of prematurity, hypoglycemia, cardiomyopathy, macroglossia, or tumors. However, the previously reported mortality of 20% is likely an overestimate given better recognition of the disorder along with enhanced treatment options. Macroglossia and macrosomia are generally present at birth but may have postnatal onset. Growth rate slows around age seven to eight years. Hemihyperplasia may affect segmental
Isolated hemihyperplasia is an abnormality of cell proliferation leading to asymmetric overgrowth of one or more regions of the body. The term hemihyperplasia has replaced the term hemihypertrophy to describe accurately the increase in cell number found in these patients. The incidence of isolated hemihyperplasia is estimated to be 1 in 86,000. Idiopathic hemihypertrophy is associated with increased risk of embryonal cancers in childhood, particularly Wilms tumor.. Hoyme et al. (1998) provided an anatomic classification of hemihyperplasia: complex hemihyperplasia is involvement of half of the body, including at least 1 arm and 1 leg; affected parts may be contralateral or ipsilateral. Simple hemihyperplasia is involvement of a single limb. See also facial hemihyperplasia.. Although isolated hemihyperplasia is a distinct clinical entity, it can also occur as a feature of overgrowth syndromes, including Beckwith-Wiedemann syndrome, neurofibromatosis, Proteus syndrome, and ...

Losses of imprinting are involved in various syndromes. Those occurring in the 11p15 region lead to Beckwith-Wiedemann and Silver-Russell Syndromes. These losses of imprinting follow a mosaic pattern, rendering their detection difficult, especially given the scarcity of available DNA in amniotic fluid. Thus, in spite of growing demand, prenatal diagnosis (PND) for imprinting abnormalities of the 11p15 region is not available.. The recent development of a quantitative PCR method that permits the methylation index (MI) of imprinted regions to be calculated renders PND technically possible. Nevertheless, because of the mosaic nature of these anomalies, it is essential to verify that the methylation pattern of the 11p15 region obtained from the amniotic fluid matches that obtained from the blood. ...
Screening tests are done in children with an increased risk of Wilms tumor. These tests may help find cancer early and decrease the chance of dying from cancer.. In general, children with an increased risk of Wilms tumor should be screened for Wilms tumor every three months until they are at least 8 years old. An ultrasound test of the abdomen is usually used for screening. Small Wilms tumors may be found and removed before symptoms occur. Children with Beckwith-Wiedemann syndrome or hemihyperplasia are also screened for liver and adrenal tumors that are linked to these genetic syndromes. A test to check the alpha-fetoprotein (AFP) level in the blood and an ultrasound of the abdomen are done until the child is 4 years old. An ultrasound of the kidneys is done after the child is 4 years old. In children with certain gene changes, a different schedule for ultrasound of the abdomen may be used.. Children with aniridia and a certain gene change are screened for Wilms tumor every three months until ...
While the results reported by Zhang et al. [2] are indeed encouraging, SYK is unlikely to be the only answer. Epigenetic alterations are widespread in many if not most malignancies, pediatric and adult alike, as shown by recent data on adult acute myeloid leukemia and colorectal cancer [4, 5]. In childhood cancer, aberrant methylation of chromosome 11p in Wilms tumor, embryonal rhabdomyosarcoma, hepatoblastoma and Beckwith-Wiedemann syndrome (BWS) is well documented, often a consequence of uniparental disomy. Termed loss of heterozygosity (LOH), in BWS this results in excessive expression of the gene encoding insulin-like growth factor 2 (IGF2) as a result of loss of control of imprinting by DNA methylation [6]. This leads to overgrowth in BWS and the development of tumors such as rhabdomyosarcoma. However, it is important to note that widespread mutation, copy number changes and other regions of LOH are also found in these tumors, emphasizing that cancer is a multistep process with many ...
Background: Congenital hyperinsulinism (CHI) is a rare heterogeneous disease. Genetic testing is crucial as identifying the underlying aetiology can guide clinical management.. Objective and hypotheses: We investigated the clinical characteristics and genetics of 20 Ukrainian patients with CHI.. Methods: Routine clinical and laboratory investigations were performed on 20 patients with hypoglycemia and unsuppressed C-peptide and p-insulin, diagnostic for CHI. Patients were sub grouped according to whether the hypoglycemia was persistent (n=12) or transient (n=8). KCNJ11 and ABCC8 were sequenced in all patients. Targeted next generation of all the known CHI genes was undertaken in 2 patients with persistent CHI. In one case features of Beckwith-Wiedemann Syndrome prompted methylation and dosage analysis of chromosome 11p15.5. 18F-DOPA PET-CT was performed on 9 cases (75%) with persistent CHI.. Results: Those with persistent CHI were diagnosed earlier compared to those was transient disease (22.5 ...

From the issue dated April 14, 2006. TENURE DENIED: Controversy is brewing at Baylor University, where Francis J. Beckwith, a prominent and widely published Christian philosopher and legal scholar, was recently denied tenure  some say for his conservative religious views.. Mr. Beckwith, 45, an associate professor and associate director of Baylors J.M. Dawson Institute of Church-State Studies, joined the faculty of the Baptist university in 2003. Since his appointment, there have been rumblings on the campus about Mr. Beckwiths affiliation with the Discovery Institute, an intelligent-design think tank, and his writings promoting the teaching of intelligent design in public schools [[Beckwith’s writings argue that teaching ID is constitutionally permissible - he has never, verbally or in print, argued that ID should be taught]].. Mr. Beckwiths supporters call his tenure denial, announced last month, a "watershed" moment for Baylor and its new president, John M. ...

Imprinting means that in some places along the human genome-about 100 genes in all-the way DNA behaves depends on which parent passes it to the offspring. Some of the genes in sperm and egg cells have chemicals called methyl molecules that attach to them, a process called methylation; these molecules can either activate or silence a gene. In some cases, the mothers copy of the gene is activated, and the fathers silenced. In others the opposite is true. The function of each of the dozens of human imprinted genes isnt yet known, but many appear to guide metabolism and growth prior to birth. When imprinting goes awry-and researchers dont understand yet why that happens-the outcome can be health problems in the baby. The last several years have seen imprinting disorders emerge from the shadows, and with them a deeper appreciation for the human genomes ability to modulate gene expression in the earliest stages of development. Scientists are also considering how imprinting errors could cause ...

6-month old male presented with macrocephaly (progressive), macrosomia, macroglossia, splenomegaly, and left-sided hemi-hypertrophy. Magnetic Resonance Imaging showed large left cerebral hemisphere and hydrocephalus with normal fourth ventricle consistent with aqueductal stenosis. There was no evidence of any lipomas or hemangiomas. There was no family history of hemi-hypertrophy. Microarray based comparative genome hybridization and chromosome analyses were negative. Workup for Beckwith-Wiedemann syndrome (BWS), Neurofibromatosis, and PTEN hamartoma tumor syndromes (PHTS) was negative. A diagnosis of Isolated Hemi-hyperplasia was made which is characterized by asymmetric overgrowth of one or more regions of the body secondary to abnormal cell proliferation with an estimated incidence of 1 in 86,000. It is associated with seizures, undescended testes, inguinal hernia, communicating hydrocephalus, bicuspid aortic valve, cushing syndrome and increased risk of embryonal tumors particularly wilms ...
Simpson-Golabi-Behmel syndrome is an X-linked condition characterized by pre- and postnatal overgrowth, coarse facies, congenital heart defects, and other congenital abnormalities (Xuan et al., 1999). It shows phenotypic similarities to Beckwith-Wiedemann syndrome (BWS; 130650), another overgrowth syndrome. See also Simpson-Golabi-Behmel syndrome type 2 (SGBS2; 300209), which has been associated with a mutation in the CXORF5 gene (300170) on chromosome Xp22. (312870) ...
We have examined a series of STR loci in a pair of monozygotic twins discordant for the phenotype of hemihypertrophy, and have shown uniparental disomy of the paternal allele at 11p15 in the affected twin.. This genetic phenomenon has been previously reported,4-6 occurring in 20 to 28% of patients in a series of sporadic cases of BWS. The mechanism of uniparental disomy is compatible with hypotheses that this overgrowth syndrome with variable expression occurs as a result of overexpression of paternally derived growth factors and/or underexpression of maternally derived growth suppressors.. The variability of phenotypic expression of BWS raises difficulty in defining diagnostic criteria. However, it should be stressed that the affected patient described here does not fit the generally used criteria for BWS,7 and that the finding of mosaic UPD supports the view that IH may be part of a spectrum of phenotypes encompassing BWS. Interestingly, in a study of 49 BWS patients, Slatter et al4 suggested ...
This gene encodes a voltage-gated potassium channel required for repolarization phase of the cardiac action potential. This protein can form heteromultimers with two other potassium channel proteins, KCNE1 and KCNE3. Mutations in this gene are associated with hereditary long QT syndrome 1 (also known as Romano-Ward syndrome), Jervell and Lange-Nielsen syndrome, and familial atrial fibrillation. This gene exhibits tissue-specific imprinting, with preferential expression from the maternal allele in some tissues, and biallelic expression in others. This gene is located in a region of chromosome 11 amongst other imprinted genes that are associated with Beckwith-Wiedemann syndrome (BWS), and itself has been shown to be disrupted by chromosomal rearrangements in patients with BWS. Alternatively spliced transcript variants have been found for this gene ...
Ribonucleoside-diphosphate reductase large subunit is an enzyme that in humans is encoded by the RRM1 gene. This gene encodes one of two non-identical subunits which constitute ribonucleoside-diphosphate reductase, an enzyme essential for the production of deoxyribonucleotides prior to DNA synthesis in S phase of dividing cells. It is one of several genes located in the imprinted gene domain of 11p15.5, an important tumor-suppressor gene region. Alterations in this region have been associated with the Beckwith-Wiedemann syndrome, Wilms tumor, rhabdomyosarcoma, adrenocortical carcinoma, and lung, ovarian, and breast cancer. This gene may play a role in malignancies and disease that involve this region. This gene is oriented in a head-to-tail configuration with the stromal interaction molecule 1 gene (STIM1), with the 3 end of STIM1 situated 1.6 kb from the 5 end of this gene.

Imprinting is the deactivation of a locus in gametes of only one sex. A maternally imprinted locus has inactive maternal alleles; a paternally imprinted locus has inactive paternal alleles. Nonimprinted genes express both maternal and paternal alleles. Some imprinted regions contain a single gene, while other imprinted regions contain multiple genes. Imprinting deactivates via chromatin alteration: covalent modification of DNA, such as cytosine methylation to form 5-methyl-cytosine; and/or modification or substitution in chromatin of specific histone types.. Imprinting occurs during gametogenesis and is a reversible process; it does not change the DNA sequence nor is it a mutation. Thus, a female carrying a paternal imprint will switch the imprint when passing it on to her offspring. Similarly, a male carrying a maternal imprint will switch the imprint when passing it on to his offspring. This conversion is controlled by imprinting centers within imprinted regions. Imprinting centers initiate ...

But then a news broadcast came on and JFK leaped up, ran to the radio, and turned up the volume to listen to it. Offended, Beckwith threw him out. Another curious observation that the book establishes is that Kennedy did not smoke and was only a social drinker. So if, as I detailed in the Mary Meyer tale, Kennedy ended up a White House coke-sniffer and acid head, it was a definite break with the past. The Blairs book established some paradigms that would be followed in the anti-Kennedy genre. First, and probably foremost, is the influence of Kennedys father in his career. In fact, Joe Kennedys hovering presence over all his children is a prime motif of the book. The second theme that will be followed is the aforementioned female associations. The third repeating pattern the Blairs established is the use of Kennedys health problems as some kind of character barometer. That because Kennedy and his circle were not forthright about this, it indicates a covert tendency and a penchant for ...

Simpson-Golabi-Behmel syndrome (SGBS) is an X-linked syndrome characterized by pre- and postnatal overgrowth (gigantism), which clinically resembles the autosomal Beckwith-Wiedemann syndrome (BWS). Deletions and translocations involving the glypican-3 gene (GPC3) have been shown to be associated with SGBS. Occasionally, these deletions also include the glypican-4 gene (GPC4). Glypicans are heparan sulfate proteoglycans which have a role in the control of cell growth and cell division. We have examined the mutational status of the GPC3 and GPC4 genes in one patient with Perlman syndrome, three patients with overgrowth without syndrome diagnosis, ten unrelated SGBS-patients and 11 BWS patients. We identified one SGBS patient with a deletion of a GPC3 exon. Six SGBS patients showed point mutations in GPC3. One frameshift, three nonsense, and one splice mutation predict a loss-of-function of the glypican-3 protein. One missense mutation, W296R, changes an amino acid that is conserved in all ...
Perlman syndrome (PS) (also called renal hamartomas, nephroblastomatosis and fetal gigantism) is a rare overgrowth disorder present at birth. It is characterized by polyhydramnios and fetal overgrowth, including macrocephaly, neonatal macrosomia, visceromegaly, dysmorphic facial features, and an increased risk for Wilms tumor at an early age. The prognosis for Perlman syndrome is poor and it is associated with a high neonatal mortality. Perlman syndrome is an uncommon genetic disorder grouped with overgrowth syndrome in which an abnormal increase is often noted at birth in the size of the body or a body part of the infant. The disorder, also called renal hamartomas, nephroblastomatosis and fetal gigantism, has also been grouped with Renal cell carcinoma.

Angelman syndrome (AS) and Prader-Willi syndrome (PWS) are neurodevelopmental disorders of genomic imprinting. AS results from loss of function of the ubiquitin protein ligase E3A (UBE3A) gene, whereas the genetic defect in PWS is unknown. Although induced pluripotent stem cells (iPSCs) provide invaluable models of human disease, nuclear reprogramming could limit the usefulness of iPSCs from patients who have AS and PWS should the genomic imprint marks be disturbed by the epigenetic reprogramming process. Our iPSCs derived from patients with AS and PWS show no evidence of DNA methylation imprint erasure at the cis-acting PSW imprinting center. Importantly, we find that, as in normal brain, imprinting of UBE3A is established during neuronal differentiation of AS iPSCs, with the paternal UBE3A allele repressed concomitant with up-regulation of the UBE3A antisense transcript. These iPSC models of genomic imprinting disorders will facilitate investigation of the AS and PWS disease processes and ...

Looking for online definition of genomic imprinting in the Medical Dictionary? genomic imprinting explanation free. What is genomic imprinting? Meaning of genomic imprinting medical term. What does genomic imprinting mean?
Peter Turchin argues, and presents data, that these frontier regions where primitive, and frankly savage, passions are channeled toward outgroups serve as the loci for new empires and mega-polities. In particular, being an ecologist, he focuses on particular ecologies as the exceptional cauldrons for state-formation: the semi-arid steppe. It is here that Turchin aligns with some of Christopher Beckwiths insights in Empires of the Silk Road. This should not be totally surprising, though we look through the glass darkly nature is fundamentally one, and history is a phenomenon rooted in nature. Beckwith attempts to generate a revisionist history of the world where the rise and fall of nomadic empires are just as salient as the ebb and flow of peasant-based civilizations, where the eruptions from the heartland echo down the centuries. And Turchin, like Beckwith, seems to hold that it is less important or relevant that the movers of history are unlettered nomads, but that they are derived from the ...
