The term mosaicism is used to describe the presence of more than one type of cell in a person. For example, a person may have some of the cells in their body with 46 chromosomes, while other cells in their body have 47 chromosomes. An example of mosaicism is mosaic Down syndrome.. About 95 percent of people with Down syndrome have trisomy 21, where there is an extra #21 chromosome in every cell of their body. Three to 4 percent of people with Down syndrome have translocation Down syndrome, where all or part of the extra #21 chromosome is attached to another chromosome. The remaining 1 to 2 percent of individuals with Down syndrome are mosaic, where there are at least two types of cells, some with the usual number of chromosomes (46 total), and others with an extra #21 chromosome (47 total). Rarely, a person can have more than two types of cell lines.. Mosaicism is usually described as a percentage. For example, when a baby is born with Down syndrome, the physician will take a blood sample to ...

Turners syndrome is associated with either monosomy or a wide spectrum of structural rearrangements of chromosome X. Despite the interest in studying (somatic) chromosomal mosaicism, Turners syndrome mosaicism (TSM) remains to be fully described. This is especially true for the analysis of TSM in clinical cohorts (e.g. cohorts of individuals with neurodevelopmental disorders). Here, we present the results of studying TSM in a large cohort of girls with neurodevelopmental disorders and a hypothesis highlighting the diagnostic and prognostic value. Turners syndrome-associated karyotypes were revealed in 111 (2.8%) of 4021 girls. Regular Turners syndrome-associated karyotypes were detected in 35 girls (0.9%). TSM was uncovered in 76 girls (1.9%). TSM manifested as mosaic aneuploidy (45,X/46,XX; 45,X/47,XXX/46,XX; 45,X/47,XXX) affected 47 girls (1.2%). Supernumerary marker chromosomes derived from chromosome X have been identified in 11 girls with TSM (0.3%). Isochromosomes iX(q) was found in 12 cases

N2 - Mosaic trisomy 8, also known as Warkany syndrome, has a well-characterized constellation of phenotypic findings. Partial trisomy 8, including mosaic cases, has also been reported, with outcome and counseling dependent on the chromosomal segment involved and whether accompanied by partial aneuploidy for other chromosomes. We present a case of a fetus mosaic for trisomy of the entire long arm (q) of chromosome 8 without additional chromosomal aberrations. The diagnosis was made by amniocentesis performed following an 18 week sonogram that showed multiple fetal anomalies. Mosaicism for trisomy 8q was confirmed by routine karyotyping and fluorescent in situ hybridization (FISH) analysis. The case proved useful for ...

Abstract: Revealing the mechanisms for neuronal somatic diversification remains a central challenge for understanding individual differences in brain organization and function. Here we show that an engineered human LINE-1 (for long interspersed nuclear element-1; also known as L1) element can retrotranspose in neuronal precursors derived from rat hippocampus neural stem cells. The resulting retrotransposition events can alter the expression of neuronal genes, which, in turn, can influence neuronal cell fate in vitro. We further show that retrotransposition of a human L1 in transgenic mice results in neuronal somatic mosaicism. The molecular mechanism of action is probably mediated through Sox2, because a decrease in Sox2 expression during the early stages of neuronal differentiation is correlated with increases in both L1 transcription and retrotransposition. Our data therefore indicate that neuronal genomes might not be static, but some might be mosaic because of de novo L1 retrotransposition ...

Individual carriers of a premutation (PM) allele with 55-200 CGG repeats are typically unmethylated and can present with clinical features defined as FMR1-associated conditions. Methods: Blood samples from 17 male PM carriers were assessed clinically and molecularly by Southern blot, western blot, PCR and QRT-PCR. Blood and brain tissue from an additional 18 PM males were also similarly examined. Continuous outcomes were modelled using linear regression and binary outcomes were modelled using logistic regression. Results: ...

Clonal mosaicism for large chromosomal anomalies (duplications, deletions and uniparental disomy) was detected using SNP microarray data from over 50,000 subjects recruited for genome-wide association studies. This detection method requires a relatively high frequency of cells (,5-10%) with the same abnormal karyotype (presumably of clonal origin) in the presence of normal cells. The frequency of detectable clonal mosaicism in peripheral blood is low (,0.5%) from birth until 50 years of age, after which it rises rapidly to 2-3% in the elderly. Many of the mosaic anomalies are characteristic of those found in hematological cancers and identify common deleted regions that pinpoint the locations of genes previously associated with hematological cancers. Although only 3% of subjects with detectable clonal mosaicism had any record of hematological cancer prior to DNA sampling, those without a prior diagnosis have an estimated 10-fold higher risk of a subsequent hematological cancer (95% confidence ...

Author Summary Hybridization between two species may sometimes lead to the formation of a third species. While this phenomenon is of interest because it can generate new species from existing variation, it is rare in animals. Therefore, the factors responsible for the origin and maintenance of hybrid species are largely unknown. Here we show that the butterfly Papilio appalachiensis appears to be a hybrid species, which received nearly equal contributions to its genome from P. glaucus and P. canadensis. Two sets of traits define P. appalachiensis hybrid phenotype: like P. canadensis it inhabits a cold habitat and has a single generation every year, and like P. glaucus it mimics a toxic butterfly and its females are dimorphic. The genes responsible for these traits are on two different sex chromosomes. Our genetic data show that P. appalachiensis inherited the sex chromosome associated with the cold habitat from P. canadensis, whereas it inherited the sex chromosome associated with mimicry and

Conclusions We herein show somatic NLRP3 mosaicism underlying MWS, probably representing a shared genetic mechanism in CAPS not restricted to CINCA syndrome. The data here described allowed definitive diagnoses of these patients, which had serious implications for gaining access to anti-interleukin 1 treatments under legal indication and for genetic counselling. The detection of somatic mosaicism is difficult when using conventional methods. Potential candidates should benefit from the use of modern genetic tools.. ...

Meiosis is a key cellular process of sexual reproduction involving the pairing of homologous sequences. In many species however, meiosis can also involve the segregation of supernumerary chromosomes, which can lack a homolog. How these unpaired chromosomes undergo meiosis is largely unknown. In this study we investigated chromosome segregation during meiosis in the haploid fungus Zymoseptoria tritici that possesses a large complement of supernumerary chromosomes. We used isogenic whole chromosome deletion strains to compare meiotic transmission of chromosomes when paired and unpaired. Unpaired chromosomes inherited from the male parent as well as paired supernumerary chromosomes in general showed Mendelian inheritance. In contrast, unpaired chromosomes inherited from the female parent showed non-Mendelian inheritance but were amplified and transmitted to all meiotic products. We concluded that the supernumerary chromosomes of Z. tritici show a meiotic drive and propose an additional feedback ...

This study was an evaluation of the role of noninvasive prenatal testing (NIPT) in the detection of trisomy 7 in prenatal diagnosis. A total of 35 consecutive cases underwent screening for trisomies by cell-free DNA testing between April 2015 and November 2017 due to suspicious NIPT results; these cases represented 0.11% of patients (35/31,250) with similar frequencies of abnormal results among the laboratories performing the tests. NIPT was offered to further screen for common fetal chromosomal abnormalities. Karyotype analysis, chromosomal microarray analysis (CMA), and next-generation sequencing (NGS) were used to detect 20, 14, and 25 patients, respectively, who accepted confirmatory diagnostic testing. High-risk results by NIPT were recorded for trisomy 7 alone in 29 women: dual aneuploidy in 4 patients and multiple aneuploidy in 2 patients. Karyotype analysis of amniotic fluid cells was normal in all 20 pregnancies, suggesting a probability of confined placental mosaicism. Further CMA data were

A trisomy 7 mosaicism (46, XX/47, XX+7) was identified by quinacrine mustard fluorescence studies in a psychiatric patient and in her daughter who also had mental illness. The aetiology of the trisomy 7 mosaicism in two generations of this family is postulated to involve an autosomal dominant gene as initially described by Zellweger and Abbo in 1965.. ...

In humans, reproduction is considered a relatively inefficient process, when compared with other mammalian species and the chance of achieving a spontaneous pregnancy after timed intercourse is at the most 20-30%. Chromosome segregation errors are a well-known inherent feature of cell division in human preimplantation embryos produced by in vitro ... read more fertilization (IVF). The occurrence of such errors, which results in embryos containing chromosomally abnormal (aneuploid) cells, is believed to be the main cause for the reported inefficiency of human reproduction, as it may lead to pre-clinical pregnancy losses. In this thesis we start by evaluating the impact of ovarian stimulation administrated to patients undergoing IVF on the development of IVF-derived human embryos. We conclude that although the use of ovarian stimulation is considered relatively safe, further studies are needed to increase the knowledge on this subject and reduce potential effects on embryo development and ...

Autosomal dominant genetic diseases can occur de novo and in the form of somatic mosaicism, which can give rise to a less severe phenotype, and make diagnosis more difficult given the sensitivity limits of the methods used. We report the case of female child with a history of surgery for syndactyly of the hands and feet, who was admitted at 6 years of age to a pediatric intensive care unit following cardiac arrest. The electrocardiogram (ECG) showed a long QT interval that on occasions reached 500 ms. Despite the absence of facial dysmorphism and the presence of normal psychomotor development, a diagnosis of Timothy syndrome was made given the association of syndactyly and the ECG features. Sanger sequencing of the CACNA1C gene, followed by sequencing of the genes KCNQ1, KCNH2, KCNE1, KCNE2, were negative. The subsequent analysis of a panel of genes responsible for hereditary cardiac rhythm disorders using Haloplex technology revealed a recurrent mosaic p.Gly406Arg missense mutation of the ...

A pillar is a firm upright support (1) for something. A pillar may stand alone or it may support a superstructure. The article of Beatrice Mintz and Willys Silvers (2) discussed here on grafting using allophenic mice is appropriately called a pillar of immunology for which the superstructure is yet to be completed.. Mintz and Silvers posed a question long considered fundamental to immunology: What is the origin of intrinsic tolerance. Intrinsic tolerance refers to the natural condition of specific nonresponsiveness to self. More than 60 years before, Ehrlich and Morgenroth had reasoned that injury and atrophy of tissues might lead to the development of immune reactions against autologous cells, but the occurrence of such reactions would be dysteleological in the highest degree (3). To explain why autologous reactions usually do not arise, Ehrlich and Morgenroth proposed that organisms must have a horror autotoxicus mediated by some regulating contrivances and believed that studying these ...

Image by Shopify Partners. After the embryo fall out has been transferred and inserted between the uterine walls, its not possible for the embryo to fall out as it is deep within the uterus and therefore you can safely continue with your normal routine after having an embryo transfer.. The transfer itself is a fairly simple procedure with very little discomfort. A thin, soft catheter is threaded through the cervix under ultrasound guidance, to be very exact in the embryo placement location, generally 1 to 2 cm from the top of the uterine cavity. After cleansing the cervix with solution, the fertility doctor will place an empty transfer catheter through the cervix into position inside the uterine cavity. Then the embryologist will bring the catheter containing the embryo(s) from the lab a few feet away, so we can minimize the time that the embryos are exposed.. Once we have the embryo(s), we feed the catheter with the embryo(s) fall out through the empty catheter that is in place. On the ...

On the basis of these results, we hypothesised that some patients with RTT may in fact carry a somatic mutation. Small deletions (from 7 to 170 bp) within the region between bp 1096 and 1165 of theMECP2 gene have been recurrently identified.5 7 9 10 12 15 16 They do not affect the two functional domains but result in the loss of one fifth of the protein. Interestingly, it has been shown that the deletion of the carboxy-terminal 63 amino acids of the MeCP2 protein impairs binding with the nucleosomal DNA during the transcription regulation process.21 These recurrent deletions may be the result of palindromic and quasipalindromic sequences within this region, which are believed to form secondary structures that render the region vulnerable to deletions. Therefore, using our fluorescent PCR approach, we reanalysed the 3′ region of the MECP2gene, between bp 1096 and 1165, in a cohort of 29 patients diagnosed as typical or atypical RTT; for these patients, we failed to detect any mutation using a ...

Very-early-onset inflammatory bowel disease (VEO-IBD) is a heterogeneous phenotype associated with a spectrum of rare Mendelian disorders. Here, we perform whole-exome-sequencing and genome-wide genotyping in 145 patients (median age-at-diagnosis of 3.5 years), in whom no Mendelian disorders were clinically suspected. In five patients we detect a primary immunodeficiency or enteropathy, with clinical consequences (XIAP, CYBA, SH2D1A, PCSK1). We also present a case study of a VEO-IBD patient with a mosaic de novo, pathogenic allele in CYBB. The mutation is present in ~70% of phagocytes and sufficient to result in defective bacterial handling but not life-threatening infections. Finally, we show that VEO-IBD patients have, on average, higher IBD polygenic risk scores than population controls (99 patients and 18,780 controls; P | 4 × 10-10), and replicate this finding in an independent cohort of VEO-IBD cases and controls (117 patients and 2,603 controls; P | 5 × 10-10). This discovery indicates that a

In this study, the puzzling phenomenon of spontaneous coexistence of D-positive and D-negative RBC subpopulations was investigated. In a representative number of 9 patients with mixed Rh phenotype, the prevailing molecular background of this condition was elucidated. Rh mosaicism involving a hematopoietic stem-cell line with LOH on chromosome 1 was demonstrated to be the key mechanism for the observed RBC phenotype anomalies.. Frequent causes of mixed Rh phenotype, such as RBC transfusion or HSCT, had been ruled out in these patients, which was also confirmed by the fact that Rh and in one case also Fy but not other blood group antigens were affected. In addition, none of the patients displayed congenital or acquired chimerism,4 as evidenced by microsatellite analysis. This result was remarkable, as spontaneous chimerism had been reported to occur quite frequently.5,46. The immunohematologic properties of the D-positive and D-negative RBC subpopulations indicated loss of one complete RH ...

XLAG is a novel genetic cause of GH excess. It usually presents at a very early age as a sporadic disease due to a de novo microduplication on the X chromosome involving the GPR101 gene in patients with gigantism (40-42). The majority of the cases are females with germline microduplication (14, 40, 42). Two familial cases have been described with transmission from affected mother to an affected son and show full penetrance (14). Somatic mosaic mutation cases have also been described in males where the mutation was identified in the pituitary tissue and/or at low level in germline (18, 41, 42). Although the originally identified Xq26.3 duplicated area involves four genes (14), only one of these, the GPR101 gene, has been found upregulated at the mRNA level in pituitary tissue. We have recently identified a patient with XLAG whose duplicated area includes only the GPR101 gene, but not the other three genes, indicating the pathogenic role of GPR101 (14, 42). Activation of GPR101, an orphan Gs ...

A hypoplastic cerebellum is incompletely formed or small but otherwise normal appearing. Hypoplastic cerebella result from reduction/premature cessation of cell production or cell migration or from excessive apoptosis in the developing cerebellum. The abnormality may involve a cerebellar hemisphere, vermis or both.. The etiology of cerebellar hypoplasia is not definitely known. Pathologic evidence of cerebellar injury due to birth asphyxia has been described. Cerebellar hypoplasia associated with hypoplasia or aplasia of the cerebellar or vertebral arteries suggests a vascular etiology. Genetic mutations with somatic mosaicism may also have a role.. Patients with diffuse hypoplasia generally have normal cerebra. The majority of patients with normal cerebra will have few symptoms related to a hypoplastic cerebellum.. ...

TSC is a rare, multi-system genetic disease that causes benign tumours to grow in the brain and on other vital organs such as the kidneys, heart, eyes, lungs, and skin. A combination of symptoms may include seizures, developmental delay, behavioural problems and skin abnormalities, as well as lung and kidney disease [1-3]. TSC is an autosomal dominant genetic disorder with an incidence of approximately 1 in 5,000 to 10,000 live births [4,5]. However, only one-third of cases are familial [6]. The apparently nonfamilial cases can represent either spontaneous mutations or mosaicism, in which only some germ cells in the affected parent express the mutant gene [6-8]. Some of these parents are asymptomatic, but most have mild abnormalities that can be detected with careful evaluation that is typically performed after TS is diagnosed in the child; the mild phenotype may reflect mosaicism in the somatic cells [8]. Another clue to the presence of mosaicism is when apparently unaffected parents have a ...

Previous studies have injected CRISPR-Cas9 after IVF, but faced mosaicism problems, characterized by embryos having a mixture of cells with and without the repaired mutation. Mosaicism would lead to organisms with some tissues or organs that bear the mutations and some that do not. In this study, the researchers injected sperm and CRISPR-Cas9 into the egg at the same time to improve the accuracy of the gene correction. Thanks to this strategy, mosaicism did not occur. CRISPR-Cas9 cut the DNA at the correct position in all tested embryos (100%) and 42 out of the 58 embryos (72.4%) did not carry the hypertrophic cardiomyopathy mutation. In other words, this technique increased the probability of inheriting the healthy gene from 50% to 72.4%. Moreover, while doing this research the scientists also discovered that human embryos have an alternative DNA repair system, where the Cas9-induced cuts in the DNA coming from the sperm are repaired using the healthy eggs DNA as a template. In the remaining ...

Dr. Fricke responded: PKS is from a genet-. ic accident that leads to the fetus having usually 2 extra copies of genes on the short arm of Chromosome 12 in some cells of the body & the normal 2 copies in other cells, called mosaicism. It can impact all organ systems & cause profound Intellectual Disability, atypical facial features & abnormal hair growth pattern.

Renal coloboma syndrome (RCS) is an autosomal dominant disorder caused by PAX2 gene mutations and characterized by renal hypoplasia and optic disc coloboma. The clinical findings were retrospectively reviewed, and all coding regions of the PAX2 gene were sequenced, in six children with RCS. A c.619_620insG mutation was detected in five patients, including two siblings, and a novel p.Arg104X mutation was detected in one patient. All the patients had progressive renal dysfunction and bilateral hypoplastic kidneys without vesicoureteral reflux (VUR), but the rate of progression to end-stage renal disease showed some diversity. The ocular manifestations showed wide variability, ranging from subtle optic disc anomalies to microphthalmia. In one family with two affected siblings, maternal germline mosaicism was suggested by an intragenic microsatellite marker study. In conclusion, there are variable renal and ocular manifestations in RCS without significant phenotype-genotype correlations. VUR is not ...

I focused on the analysis of a very promising candidate gene, the Mlf1 adapter molecule (Madm). In this study, we implicate for the first time a central role for Madm in the nervous system. Madm is a pseudo kinase which was previously shown to be an adaptor for unknown growth-related signaling pathways in Drosophila (Gluderer S. et al. 2010). We demonstrate that Madm controls multiple aspects of synapse development and refinement at the Drosophila neuromuscular junction (NMJ). First, Drosophila madm mutants displayed prominent synaptic stability and degeneration defects. Second, Madm mutant animals showed severe morphological alterations as well as reduced growth of NMJs. Third, nerves in Madm mutant animals displayed huge swellings and varicosities - a hallmark of neurodegenerative diseases in mammals and humans e.g. in Parkinsons and Alzheimers disease. Fourth, Madm depletion resulted in the accumulation of the presynaptic marker Bruchpilot (BRP) in motoneuron axons. In addition, we could ...

Various sporadic human diseases, ranging from autism spectrum disorders to congenital heart disease and muscular dystrophies, are caused by de novo mutations. In a classical model, these are assumed to occur at a low rate in the parental germ cells (10-4-10-8). Consequently, de novo mutations identified by genetic testing are often assigned a low risk of recurrence in siblings. This idea is increasingly challenged by the detection of mosaicism in the parents. However, previous studies were largely restricted to the analysis of somatic tissues, whose genetic information is, by definition, not transmitted to the next generation. Here, we directly assessed the presence of inherited de novo mutations in paternal sperm and discovered abundant, germline restricted mosaicism. These samples were collected from a panel of fourteen families with a proband presenting with autism spectrum disorder. For all of these a candidate de novomutation had been identified in our ongoing genetic studies of this ...

Huang H., Lu F.I., Jia S., Meng S., Cao Y., Wang Y., Ma W., Yin K., Wen Z., Peng J., Thisse C., Thisse B., Meng A.. Angiomotin (Amot), the founding member of the Motin family, is involved in angiogenesis by regulating endothelial cell motility, and is required for visceral endoderm movement in mice. However, little is known about biological functions of the other two members of the Motin family, Angiomotin-like1 (Amotl1) and Angiomotin-like2 (Amotl2). Here, we have identified zebrafish amotl2 as an Fgf-responsive gene. Zebrafish amotl2 is expressed maternally and in restricted cell types zygotically. Knockdown of amotl2 expression delays epiboly and impairs convergence and extension movement, and amotl2-deficient cells in mosaic embryos fail to migrate properly. This coincides with loss of membrane protrusions and disorder of F-actin. Amotl2 partially co-localizes with RhoB-or EEA1-positive endosomes and the non-receptor tyrosine kinase c-Src. We further demonstrate that Amotl2 interacts ...

Are there specific concerns about mosaicism, outcome data, etc., and decisions patients might be making? I am very comfortable with this literature, and focus on evidence-based patient decision-making.

If the physician has a specific practice policy on these issues, Id love to know about it in advance.. ...

The new research suggests that the cells may die because of naturally occurring gene variation in brain cells that were, until recently, assumed to be genetically identical. This variation - called somatic mosaicism - could explain why neurons in the temporal lobe are the first to die in Alzheimers, for example, and why dopaminergic neurons are the first to die in Parkinsons.. This has been a big open question in neuroscience, particularly in various neurodegenerative diseases, said neuroscientist Michael McConnell, PhD, of UVAs Center for Brain Immunology and Glia (BIG). What is this selective vulnerability? What underlies it? And so now, with our work, the hypotheses moving forward are that it could be that different regions of the brain actually have a different garden of these [variations] in young individuals and that sets up different regions for decline later in life.. A Most Unexpected Outcome. The finding emerged unexpectedly from McConnells investigations into schizophrenia. ...

Variegation in Drosophila is a manifest illustration of the important role played by chromatin structure in gene expression. Mutants of modulo (mod) have been isolated and this gene is shown to be a dominant suppressor of variegation. Null mutants are recessive lethal with a melanotic tumour phenotype. The mod protein directly binds DNA, which indicates that it may serve to anchor multimeric complexes promoting chromatin compaction and silencing (Garzino, 1992). To analyse the consequences of mod loss of function in mitotically active cells of the imaginal disc, clones of cells homozygous for the null allele A4-4L8 were generated by FLP-mediated recombination. In these experiments, clones were identified on the adult epidermis of mosaic animals by the loss of yellow and Stubble bristle markers. mod-deficient clones were found in adult flies on head, thorax, legs and abdomen. They present three main features: (1) they are systematically of reduced size when compared to controls (wild-type clones ...

Dekapentagonal maps depict the phylogenetic relationships of five genomes in a visually appealing diagram and can be viewed as an alternative to a single evolutionary consensus tree. In particular, the generated maps focus attention on those gene families that significantly deviate from the consensus or plurality phylogeny. PentaPlot is a software tool that computes such dekapentagonal maps given an appropriate probability support matrix. The visualization with dekapentagonal maps critically depends on the optimal layout of unrooted tree topologies representing different evolutionary relationships among five organisms along the vertices of the dekapentagon. This is a difficult optimization problem given the large number of possible layouts. At its core our tool utilizes a genetic algorithm with demes and a local search strategy to search for the optimal layout. The hybrid genetic algorithm performs satisfactorily even in those cases where the chosen genomes are so divergent that little phylogenetic

RESULTS. Fluorescence in-situ hybridisation detected 558 (9.5%) patients with chromosomal abnormalities. Abnormal ultrasounds (70%) and maternal serum screens (21%) were the most indicative of chromosomal abnormalities. When comparing fluorescence in-situ hybridisation data with karyotype results for the five chromosomes of interest, the sensitivity and specificity were 99.3% and 99.9%, respectively. When comparing fluorescence in-situ hybridisation data with karyotype results for all chromosomes, the sensitivity decreased to 86.8%, whereas the specificity remained at 99.9%. Of 643 cases with karyotype abnormalities, 85 were fluorescence in-situ hybridisation-negative (false negative rate, 13.2%), which included structural rearrangements, chromosome mosaicism, and other trisomies. Despite abnormal ultrasound indications, fluorescence in-situ hybridisation missed 32 cases which included structural rearrangements, mosaicisms, and other trisomies ...

The development of the adult visual system of Drosophila requires the establishment of precise retinotopic connections between retinal photoreceptor cell axons and their synaptic partners in the optic lobe of the brain. To assess the role of axon-axon interactions in retinal axon guidance, we used genetic methods to disrupt the normal spatiotemporal order of retinal axon ingrowth. We examined retinal axon projections to the developing first optic ganglion, the lamina, in two mutants in which reduced numbers of ommatidia develop in the eye imaginal disk. We find that in the developing lamina of these mutants, sine oculis and Ellipse, retinal axons project to proper dorsoventral positions despite the absence of the usual array of neighboring retinal axons. In a second approach, we examined animals that were somatic mosaics for the mutation, glass. In glass- animals, retinal axons project aberrantly and the larval optic nerve is absent. We find that in the developing lamina of glass mosaic animals, wild

The main objective ofthis study was to determine the presence and level of mosaicism for chromosomal aneuploidy in several cases of fetal demise that had previous indications of chromosome aberrations. The presence of aneuploidy was determined using fluorescence in situ hybridization (FISH) probes. Techniques that were utilized in attempts to prepare several tissue types for FISH are described. The analyses made with FISH provided useful data on the chromosomal makeup oftwo of the cases studied. In one case FISH results showed that the product of conception (POC) did not contain the trisomy 18 that is present at low levels in the mothers blood cells. In the other case the miscarried fetus was previously identified as being mosaic for trisomy X. In this research project the presence ofvarying levels of trisomy X in both embryonic and placental tissue was ...

Pallister Killian syndrome (PKS, OMIM 601803) is a rare genetic disorder with a distinct phenotype caused by tissue- limited mosaicism tetrasomy of the short arm of chromosome 12, which usually cytogenetically presents as an extra isochromosome 12p. Wide phenotypic variability in PKS has been reported, ranging from pre-to perinatal death due to multiple congenital anomalies, especially diaphragmatic hernia, and classic phenotypes including seizures, severe developmental delay, macrosomia at birth, deafness, and distinct dysmorphic features, such as coarse face, temporal alopecia, a small nose with anteverted nostrils, long philtrum, and hypo−/hyper- pigmented streaks on the skin. Karyotypes obtained from cultured peripheral lymphocytes of 13 cases, who were diagnosed as PKS, were normal, while karyotypes obtained from cultured skin samples and buccal mucosa revealed the supernumerary mosaic i(12p). Mosaic karyotype was found in both fibroblast and buccal mucosa in 14 of 15 patients in our series,

Gaucher disease (GD) is a recessively inherited autosomal lysosomal storage disease, the most severe of which is type 2, an acute neuronopathic form. We report an affected infant who inherited one mutant allele, Arg257Gln (c.887G,A; p.Arg296Gln) from his father, while the second, Gly202Arg (c.721G,A; p.Gly241Arg) arose by either maternal germline mosaicism or as a de novo mutation. This is the first time mutation Gly202Arg has been reported to be inherited non-traditionally. This report is part of a growing literature suggesting that GD can be inherited via germline or de novo mutations, and emphasizes that it is critical for clinicians to consider such inheritance when making diagnostic decisions or providing genetic counseling ...

Structural copy number variation (CNV) is a frequent cause of human variation and disease. Evidence is mounting that somatic acquired CNVs are prevalent, with mosaicisms of large segmental CNVs in blood found in up to one percent of both the healthy and patient populations. It is generally accepted that such constitutional mosaicisms are derived from postzygotic somatic mutations. However, few studies have tested this assumption. Here we determined the origin of CNVs which coexist with a normal cell line in nine individuals. We show that in 2/9 the CNV originated during meiosis. The existence of two cell lines with 46 chromosomes thus resulted from two parallel trisomy rescue events during postzygotic mitoses. ...

Turners syndrome, one of the most common sex chromosome abnormalities in females, is caused by loss of part or all of an X chromosome. We report a case of mosaic Turners syndrome, posted for elective cesarean delivery under low-dose sequential combined spinal epidural anesthesia. The unique features of this case were the combination of an anticipated difficult airway and both short stature and scoliosis in the lumbar region. A titrated combined spinal-epidural technique was performed in order to avoid hemodynamic instability, which could have been exacerbated in the presence of cardiovascular deformities that accompany this syndrome in many cases ...

Did you know there are three different chromosomal variations that can occur with the 21st chromosome?. Complete trisomy 21 is the most common. Ordinarily, when an egg and a sperm are joined at conception, a single cell is created with a total of 46 chromosomes. As the cells divide, each cell contains the same 46 chromosomes. But in the case of a complete trisomy 21, an anomaly during the formation of the egg or the sperm results in either one having an extra chromosome. So after the egg and sperm unite, the resulting cells will have three copies of chromosome 21. The complete extra copy of chromosome 21 is in all of the persons cells-or a complete trisomy. Augie has complete trisomy 21. His extra 21st chromosome is in every cell of his body!. Mosaic trisomy 21 occurs when the extra 21st chromosome is in some but not all of a persons cells. Just like the mosaic style of art made up of different colors, a person with mosaic trisomy 21 has more than one type of chromosomal makeup. It could occur ...

In the present study we have characterized on the genetic aspects and clinical ground the largest cohort of ring 20 patients reported till now. All patients but the youngest one (MM, 3 years old) presented the typical seizure disorder associated with r(20) chromosome, with a mean age at seizure onset of 9 years. Epilepsy onset has been reported in paediatric, adolescent and adult age. Patients with an early epilepsy onset (within the first year of age) have been reviewed by Ville et al: all exhibited severe psychomotor delay before seizure onset and a percentage of r(20) chromosome cells ranging from 87 to 100% [19].. More than 60 cases of patients with a non supernumerary r(20) chromosome mosaicism have been reported, but the great majority have been investigated only with conventional cytogenetic analysis.. Ring(20) syndrome is characterized by phenotypic variability, particularly concerning dysmorphism, malformations, mental retardation and behavioural disturbances [20]. The severity of ...

The very large presented sample set and consistency in cytogenetic methodology, especially the analysis of both placental layers performed on all CV samples will enable genetic counselors to determine the risk of fetal involvement and the clinical relevance of an identified mosaic condition.

Mosaicism is defined as the presence of two or more genetically distinct cellular populations in an individual who developed from a single zygote. With the advent of genome-wide association studies, it is possible to evaluate the relative intensities of the genotype signals to detect large structural mosaicism in human populations. We performed an analysis of germline DNA derived from blood or buccal specimens from 24,849 individuals in 46 cancer-related studies using a modified mosaic alteration detection algorithm on renormalized B-allele frequencies and log2 relative probe intensity ratios from commercially available Illumina SNP arrays. Overall, we confirmed our previously reported findings (Jacobs et al Nat Gen 2012) including a similar distribution of types of events with respect to chromosomal position, an increase with age (overall and in cancer free-controls) and an increase in men versus women. Our segmentation algorithm detected 341 clonal mosaic events ,2 Mb in size in 168 ...

Background Squalius alburnoides is an Iberian cyprinid fish resulting from an interspecific hybridisation between Squalius pyrenaicus females (P genome) and males of an unknown Anaecypris hispanica- like species (A genome). S. alburnoides is an allopolyploid hybridogenetic complex, which makes it a likely candidate for ploidy mosaicism occurrence, and is also an interesting model to address questions about gene expression regulation and genomic interactions. Indeed, it was previously suggested that in S. alburnoides triploids (PAA composition) silencing of one of the three alleles (mainly of the P allele) occurs. However, not a whole haplome is inactivated but a more or less random inactivation of alleles varying between individuals and even between organs of the same fish was seen. In this work we intended to correlate expression differences between individuals and/or between organs to the occurrence of mosaicism, evaluating if mosaics could explain previous observations and its impact on the ...

Its a groundbreaking discovery that, if confirmed with future tests and trials to be safe and effective, could have a massive impact on the medical community for many years to come.. Genome editing has potential for the targeted correction of germline mutations, the abstract states. Here we describe the correction of the heterozygous MYBPC3 mutation in human preimplantation embryos with precise CRISPR-Cas9-based targeting accuracy and high homology-directed repair efficiency by activating an endogenous, germline-specific DNA repair response. Induced double-strand breaks (DSBs) at the mutant paternal allele were predominantly repaired using the homologous wild-type maternal gene instead of a synthetic DNA template. By modulating the cell cycle stage at which the DSB was induced, we were able to avoid mosaicism in cleaving embryos and achieve a high yield of homozygous embryos carrying the wild-type MYBPC3 gene without evidence of off-target mutations.. ...

Genetic variations of SP-C gene are known to cause interstitial lung disease. In previous studies 55 patients have been described focussing on the genetic abnormalities and clinical course.. Here we report the data of children with SP-C mutations collected between 1998 and 2010. Lung biopsy findings and previous radiological imaging studies were re-examined using up to date classifications.. All 11 children identified had heterozygous mutations in the SP-C gene, six of which carried I73T and five other mutations (H59R, G74V, C121F, E191X, A112T). Age at onset of symptoms ranged from birth to 11 years; however most presented with postnatal respiratory distress syndrome or later with tachypnea, cough and failure to thrive. Chest computer tomography showed a variety of different patterns including ground glass attenuation, mosaic pattern, lung fibrosis and cysts. Initial diagnosis was made by genetic testing alone in 6 of 11 cases and by lung biopsy in 5 patients. Histology pattern included non ...

I am a 38 year old female with Turner Syndrome, diagnosed at age 17. Each doctor I have gone to keep on estrogen therapy never seemed concerned with my heart, kidneys or any other possible hidden problems I might have. When I want to discuss tests to ensure my health, they change the subject. My karyotype is 45XO, which indicates pure Turners, but even my present doctor, who is a specialist, doesnt seem concerned with any other health problems besides hormone therapy. Am I just being overconcerned? From the research Ive done it is not uncommon for Turner girls and women to have underlying health problems. Turner Syndrome is caused by the complete or partial absence of one of the two X chromosomes usually found in women. It effects approximately one in every 3000 women and is either diagnosed at the time of birth, or at the time of adolescence when menstruation fails to begin. It is indicated by minimal sexual development, including the failure of menstruation to begin, and the lack of breast ...

As the (proud) owner of a 1960 Turner Sports 950 I can fully understand that most people (and even many car specialists) have never heard of Turner as a UK sportscar manufacturer.. I gladly refer to the excellent Turner website www.turnersportscars.co.uk for more information about the history, background and achievements of the brand. It will immediately become clear that Mr. Jack Turner was actively involved in (and had a large contribution to) the British autosports scene of the Fifties and Sixties with clear successes in many races and championships.. When I found my (Alexander) Turner in the early Eighties it was in a very poor state and in fact consisted of a collection of parts. It took me about 12 years before I actually could drive the car. As in those days there was even less information available about Turners, it was a long and troublesome road to get sufficient information to re-assemble the Turner in a historically correct way. I literally relied on a few Turner enthusiast ...
