Rationale: Conventional prenatal diagnosis (PND) for single-gene disorders requires invasive procedures, either chorionic villus sampling between 11 and 14 weeks gestation or amniocentesis after 15 weeks. Although these approaches to obtain foetal DNA currently provide the golden standard for PND, the invasive procedures carry a risk of miscarriage of 0.5-1%. A reliable non-invasive alternative has long been sought. Circulating cell-free foetal (cff) nucleic acids (DNA and RNA), which are present in maternal blood during pregnancy, can be used for non-invasive prenatal testing (NIPT). NIPT for some chromosomal anomalies (trisomy 21, 13, 18) is now validated. NIPT for other chromosomal anomalies is still under development. NIPT of single-gene disorders is technically very challenging, due to the predominance of maternal DNA sequences, Some small studies have shown that a very limited number of monogenic genetic disorders can currently be diagnosed in maternal blood. In general de novo mutations ...

The alpha globin gene cluster is far from static. It shows remarkable diversity within and among populations, both in gene number and the pattern of polymorphisms involving the HVRs. The deletions which have given rise to alpha o thalassemia appear to have resulted from rare genetic events and the affected chromosomes have been distributed among localized populations by selection. On the other hand, the deletions which have given rise to at least one of the alpha+ thalassemias seem to have occurred on multiple occasions in different populations. The genesis of this condition, the commonest single gene disorder, may reflect the concerted evolution of the alpha globin genes, and the alpha+ thalassemias may have arisen as a by-product of this evolutionary process. The existence of such a polymorphic gene family and the fact that its mutations are the commonest single gene disorders in man, provide us with a remarkable, natural model for studying population genetics at the molecular level.

Washington, DC - With proper management, women with certain genetic conditions are able to achieve normal pregnancy outcomes, according to a new Committee Opinion from the American College of Obstetricians and Gynecologists (ACOG). This reflects an increased understanding of these rare genetic conditions, as well as new reproductive technologies and improved medical and surgical care.. The opinion, Identification and Referral of Maternal Genetic Conditions in Pregnancy, was released by the Colleges Committee on Genetics.. For women with genetic conditions, preconception evaluation by appropriate obstetrician-gynecologist specialists is recommended. This can help a woman to optimize her own health before pregnancy, review her health risks associated with pregnancy and delivery, screen the womans partner for carrier status, counsel about potential inheritance by the offspring, and create a plan of care that encompasses the ongoing control of her condition as well as her desire for a healthy ...

Human gene mutations resulting in specific disease phenotypes were first reported in the scientific literature over 50 years ago [1, 2]. Since then, protein and nucleotide sequence changes associated with human disease have accumulated at a rapid rate. A large body of literature has appeared on human disease-associated mutations, normal sequence variation, and alterations that acquire pathological significance when combined with other deleterious alleles or second-site mutations. With this information compiled into organized databases [3, 4], it is now possible to conduct large-scale, comprehensive analyses of human disease genes. Such studies acquire additional discriminatory power with the availability of multiple genome sequences from model organisms, as comparative studies can provide novel evolutionary insights into the selective relevance of genetic changes. In the present study, we have used a collection of nearly 1,200 human disease gene sequences to perform a large-scale analysis of ...

The Human Gene Mutation Database (HGMD®) represents a comprehensive collection of germ-line mutations in nuclear genes, underlying or associated with human inherited disease. This database was originally established for the study of mutational mechanisms in human genes but has now acquired a much broader utility in that it embodies an up-to-date and comprehensive reference source to the spectrum of inherited human gene lesions. HGMD records all germ-line disease-causing mutations and disease-associated/functional polymorphisms reported in the literature, and provides these data in a readily accessible format to all interested parties, whether they are from an academic, clinical or commercial background. HGMD now constitutes, de facto, the central disease-associated mutation database available to the scientific community. The data comprise single base-pair substitutions in coding (e.g. missense and nonsense), regulatory and splicing-relevant regions of human nuclear genes, micro-deletions and ...

My laboratory research is focused on three main topics. We are investigating the cis and trans factors that are important for the control of globin gene expression. Second, we are devising new approaches for molecular diagnosis of genetic diseases. Our recent work is to recover fetal cells from maternal blood in order to diagnose single gene disorders. Finally, we are studying methods of directing genes into target cells for tissue-specific gene transfer with the potential of in vivo administration of therapeutic genes.. ...

Understanding patterns of inheritance This presentation builds on session 1 exploring patterns of inheritance Patterns of inheritance The objectives of this presentation are to: • Understand how genes are inherited • Understand the differences between the inheritance patterns associated with Autosomal dominant, Autosomal recessive, Xlinked recessive and chromosomal abnormalities • Understand that the environment can impact on some common complex conditions So how are genes passed on from parent to child? Gene • Genes in the cell nucleus are physically located on 23 pairs of chromosomes • One set of 23 chromosomes is inherited from each parent • Therefore, of each pair of genes, one is inherited from a persons mother, and one from their father Chromosome Diagram showing just one pair of the 23 pairs of chromosomes in the cell nucleus. The location of one of the genes on this chromosome is shown. Classification of genetic disorders Single Gene Disorders Alterations in single genes ...

The burden of inherited disorders of hemoglobin, the commonest group of single gene disorders in India is huge. With a population of 1.21 billion and an average prevalence of β-thalassemia carriers being around 3.5-4%, there would be 35-45 million carriers and the estimated number of births of affected babies annually would be 10,000-12,000. The carrier rates vary from 1-17% in different ethnic groups. Apart from β-thalassemia, Hb E is common in the north eastern region and in West Bengal (4 to , 50%) and Hb S is prevalent in parts of central, western and eastern India (5-40%). Thus interaction of the β-thalassemias with these Hb variants is not uncommon and can lead to a severe disorder.. One way to combat the burden is by prenatal diagnosis but the only approach to reduce the national burden is by a comprehensive community control programme. Awareness is very limited in different states (,20% among pregnant women) and the entire public health infrastructure from medical colleges to district ...

Diagnostic testing. Diagnostic testing is used to identify or confirm the diagnosis of a disease or condition in a person or a family. Diagnostic testing gives a yes or no answer in most cases. It is sometimes helpful in determining the course of a disease and the choice of treatment. Examples of diagnostic testing include chromosome studies, direct DNA studies, and biochemical genetic testing.. Predictive genetic testing. Predictive genetic testing determines the chances that a healthy individual with or without a family history of a certain disease might develop that disease. There is predictive testing available for some adult-onset conditions (those diseases which manifest themselves in adulthood) such as some types of cancer, cardiovascular disease, and some single gene disorders.. Presymptomatic genetic testing. Presymptomatic genetic testing is used to determine whether persons who have a family history of a disease, but no current symptoms, have the gene alterations associated with ...

A couple of months ago I signed up to send a tube full of saliva to a company called 23andMe. After seemingly endless spitting and six weeks of waiting, I received an email: my DNA report was ready.. My reason for signing up was a geeky fascination with the world of genetics. Ever since my first encounters with the subject at school, I have wanted to understand more about the incredible code of life lying within each of our cells and how this relates to human development, disease and behaviour. This fascination led me to be curious about my own hidden genetic liabilities.. What do the results reveal? Well, a lot of things I could have told you myself. I have high coffee metabolism. I have blue eyes and straight hair. However, some things are more enlightening; I now have an indication of my risk of 11 diseases including Alzheimers, breast cancer and Parkinsons as well as my carrier status for over 40 single gene disorders. The ancestry report correctly reveals my grandparents genetic origins, ...

Background Analysis of cell free fetal (cff) DNA in maternal plasma is used routinely for non invasive prenatal diagnosis (NIPD) of fetal sex determination, fetal rhesus D status and some single gene disorders. True positive results rely on detection of the fetal target being analysed. No amplification of the target may be interpreted either as a true negative result or a false negative result due to the absence or very low levels of cffDNA. The hypermethylated RASSF1A promoter has been reported as a universal fetal marker to confirm the presence of cffDNA. Using methylation-sensitive restriction enzymes hypomethylated maternal sequences are digested leaving hypermethylated fetal sequences detectable. Complete digestion of maternal sequences is required to eliminate false positive results. Methods cfDNA was extracted from maternal plasma (n = 90) and digested with methylation-sensitive and insensitive restriction enzymes. Analysis of RASSF1A, SRY and DYS14 was performed by real-time PCR. Results

Enhancers are short DNA sequences that can be bound by transcription factors to boost the expression of their target genes. Recent advances in the study of gene regulatory mechanisms have suggested that enhancers are typically 50-1500 bp long, located either upstream or downstream from the transcription start site of their target genes. Besides, enhancers are believed to cooperate with promoters to regulate the transcription of genes in a cis-acting and tissue specific manner, making these short sequences crucial in the understanding of gene regulatory mechanisms, and thus receiving more and more attentions in not only genomic and epigenomic studies but also the deciphering of genetic basis of human inherited diseases [1-3].. The identification of enhancers is usually done by using high-throughput sequencing techniques. For example, Heintzman and Ren used ChIP-seq experiments to establish a landscape of binding sites for individual transcription factor [4]. However, it is not practical to ...

How do gene disorders develop in a child and the different types of disorders. Includes information on genetic testing and who is more at risk.

PGD has become a relatively recent indication for IVF. PGD allows diagnosis at three levels: sex chromosome abnormalities/aneuploidy, structural chromosomal abnormalities, and single-gene diagnosis. The first reported cases of PGD were undertaken for sex determination of embryos to prevent transmission of X-linked genetic disorders. These initial cases were reported in 1989. Subsequently, PGD was used to prevent single-gene disorders such as cystic fibrosis. The two most common single-gene disorders diagnosed by PGD are cystic fibrosis and sickle cell disease.97 Recently, the indications for PGD have been expanded to include the diagnosis of embryo aneuploidy in women of advanced maternal age, previous IVF failures, and history of previously affected embryos or offspring. Diagnosis of structural chromosomal abnormalities in couples with balanced translocations is also possible with PGD, particularly in the treatment of recurrent miscarriage. Recently, whole-genome amplification with comparative ...

Genetic defects are a fact of life. We are fortunate today to have technology available that makes a defect manageable instead of potentially debilitating to business the way it was just a few decades ago. But no matter how fancy the DNA tests get, managing genetic conditions successfully takes transparency, time, and thought. Over the last several years, the American Angus Association (AAA) has updated the protocols on several genetic conditions that have been discovered, allowing their members and clients to continue to improve Angus genetics. All breeds of beef and dairy cattle have identified recessive genetic conditions, explains Dr. Dan Moser, President of Angus Genetics Inc. (AGI), owned by the AAA. Some, dwarfism for example, were identified in the 1950s, long before genetic testing was available. In order to identify carriers the suspect pedigrees had to be strategically bred and it just took too much time and too much money to test through designed matings. Prior to joining AGI, ...

Doctors Ask: Hereditary human diseases - diseases caused by chromosomal and gene defects. The basis of hereditary diseases are genetic, chromosomal and mitochondrial violations of hereditary information. Do not be confused with hereditary and congenital diseases. Congenital diseases are caused not only by hereditary but also by external factors, for example, the negative influence on the embryo of chemicals, drugs or irradiation.

Scientists have discovered a way to bypass the type of mutation that causes about a third of human genetic diseases.. Experiments in yeast have shown how chemical modifications can allow a cells machinery to ignore mistakes in DNA known as nonsense mutations. These stop the machinery prematurely during protein production, resulting in a shorter-than-usual protein that may function incorrectly or not at all.. For proteins to be produced in the cell, molecules called mRNA translate the information stored within DNA into amino acids, which are the building blocks of proteins. At the end of this mRNA there is normally a stop codon - a three-letter sequence that tells the machinery to cease activity - but problems can arise if this appears in the wrong place.. The researchers, from the University of Rochester Medical Centre in the USA, hope their work will lay the foundations for better treatments of some common diseases. In an interview with the Guardian, Professor Yitao Yu said: Our work is still ...

Preimplantation genetic haplotyping (PGH) is a clinical method of preimplantation genetic diagnosis (PGD) used to determine the presence of single gene disorders in offspring. PGH provides a more feasible method of gene location than whole-genome association experiments, which are expensive and time-consuming. PGH differs from common PGD methods such as fluorescence in situ hybridization (FISH) and polymerase chain reaction (PCR) for two primary reasons. First, rather than focusing on the genetic makeup of an embryo PGH compares the genome of affected and unaffected members of previous generations. This examination of generational variation then allows for a haplotype of genetic markers statistically associated with the target disease to be identified, rather than searching merely for a mutation. PGH is often used to reinforce other methods of genetic testing, and is considered more accurate than certain more common PGD methods because it has been found to reduce risk of misdiagnoses. Studies ...

Duchenne Muscular Dystrophy, an inherited and progressive muscle wasting disease, is one of the most common single gene disorders found in the developed world. In this fourth edition of the classic monograph on the topic, Alan Emery and Francesco Muntoni are joined by Rosaline Quinlivan, Consultant in Neuromuscular Disorders, to provide a thorough update on all aspects of the disorder. Recent understanding of the nature of the genetic defect responsible for Duchenne Muscular Dystrophy and isolation of the protein dystrophin has led to the development of new theories for the diseases pathogenesis. This new edition incorporates these advances from the field of molecular biology, and describes the resultant opportunities for screening, prenatal diagnosis, genetic counselling and from recent pioneering work with anti-sense oligonucleotides, the possibility of effective RNA therapy. Although there is still no cure for the disorder, there have been significant developments concerning the gene basis, ...

Genetics is a family affair. Even though our understanding of complex polygenic disorders has recently benefited from studying large numbers of unrelated cases and controls, familial studies can be very powerful in single gene disorders: Linkage studies of familial conditions with even a small number of related individuals can be sufficient to implicate a genetic region. However, a classic problem with this technique is that the associated genetic interval can be large and contain many genes, and therefore it can be very difficult to determine which one is causal. In a recent study, Mele et al. (1) use familial linkage in combination with modern sequencing techniques to address this classical conundrum and identify gene variations that cause the human kidney disease focal segmental glomerulosclerosis.. Focal segmental glomerulosclerosis is a severe kidney disease that results in loss of protein in the urine and renal failure. Familial forms exist, and these familial cases are often severe and ...

To unravel autism, researchers are examining its clinical heterogeneity, genetic risk architecture, and how it alters brain connections and function. One of the difficulties in approaching autism is that a variety of genetic mutations can result in autistic behaviors, and only a few of these mutations have been identified. Bear himself has been probing the single gene disorder, Fragile X syndrome (responsible for about 5% of the cases of fullblown autism.) In Fragile X, the FMR1 gene is silenced, leading to a missing protein that serves as a key regulator of brain proteins involved in neuron communication. Without FMR1, the brakes are missing, and theres excessive protein synthesis leading to altered brain function ...

In our validation study, PheRS was very effective in identifying patients with diagnosed Mendelian disease by using only the phenotypic signatures. Applying PheRS to a genotyped population, we found an increased burden of phenotypes among individuals with rare variants in Mendelian disease genes. Sequencing identified or confirmed second rare variants in four individuals, three of whom had the highest PheRS among all heterozygotes or homozygotes for that variant. In vitro studies provided supporting evidence of pathogenicity for all three variants tested.. Although our approach relies on many decades of accumulated knowledge about the phenotypic imprint of Mendelian disease, the method itself is simple to implement. Our ability to replicate results in an external cohort suggests that it is portable and would therefore be applicable to data sets such as those of the Million Veteran Program, UK Biobank, and the All of Us Research Program (All of Us is a service mark of the U.S. Department of ...

Different models have been proposed for the expansion of triplet repeats, most of which presume the formation of alternative DNA structures in repeat tracts. One of the most likely structures, slipped strand DNA, may stably and reproducibly form within triplet repeat sequences. The propensity to form slipped strand DNA is proportional to the length and homogeneity of the repeat tract. The remarkable stability of slipped strand DNA may, in part, be due to loop-loop interactions facilitated by the sequence ...

Preimplantation genetic testing (PGT) involves testing for abnormal chromosomes before transferring the embryos to the uterus. Genetic testing Scottsdale az has been at the forefront in selecting embryos that are free of chromosomal abnormalities to increase the probability of delivering a healthy baby. The process is carried out in the lab through the utilization of Vitro fertilization (IVF). Several cells from each embryo are used for genetic testing. The healthy embryos are then introduced to the uterus, where it attaches to its lining for a successful pregnancy. The possible candidates for PGD include individuals with chromosomal disorders, women from 35 years of age and above, Women with constant pregnancy loss, women with numerous failed fertility treatment, people with single-gene disorders, and individuals with sex-linked genetic disorders. The procedure between PGD and IVF is similar, with an extra step in PGD where embryos are checked for a severe genetic condition. According to the ...

Genetic testing is currently available for many genetic conditions. However, some conditions do not have a genetic test; either the genetic cause of the condition is unknown or a test has not yet been developed. In these cases, a combination of the approaches listed above may be used to make a diagnosis. Even when genetic testing is available, the tools listed above are used to narrow down the possibilities (known as a differential diagnosis) and choose the most appropriate genetic tests to pursue.. A diagnosis of a genetic disorder can be made anytime during life, from before birth to old age, depending on when the features of the condition appear and the availability of testing. Sometimes, having a diagnosis can guide treatment and management decisions. A genetic diagnosis can also suggest whether other family members may be affected by or at risk of a specific disorder. Even when no treatment is available for a particular condition, having a diagnosis can help people know what to expect and ...

Abstract The medical model of disease holds that manifestations are the result of a process that has a cause. The manifestations of disease are assembled in diagnosis and they constitute a taxonomy. The process which underlies them is the pathogenesis of disease. The cause of disease comprises either an event that overwhelms homeostatic mechanisms (an extrinsic cause) or one that undermines them (an intrinsic cause). Most diseases involve a combination of both (a multifactorial cause).. Abstract This text has three unifying themes. The first, and central, theme is that the causes of the diseases described are mutations (intrinsic). Because these mutations are often expressed as disadaptive phenotypes (i.e., clinical manifestations) in the universal environment, they may cause diseases that are simply inherited and classified as Mendelian or single-gene disorders. Some chapters describe more complex causes with non-Mendelian inheritance, as in the cases of Down syndrome (Chap. 63, a chromosomal ...

Mn homeostasis is tightly regulated via intestinal absorption and hepatobiliary and intestinal excretion. In this issue of the JCI, Mercadante and colleagues explored the role of the metal transporter Slc30a10 in vivo using a mouse model system. The authors used whole-body and tissue-specific gene knockouts to show that Slc30a10 is paramount for Mn excretion in the liver and small intestines. These findings provide further insights into mechanisms for Mn homeostasis as well as potential targets for addressing Mn-associated disorders or environmental exposures.. ...

Monogenic diseases result from modifications in a single gene occurring in all cells of the body. Though relatively rare, they affect millions of people worldwide. Pure genetic diseases are caused by a single error in a single gene in the human DNA. The single-gene or monogenic diseases can be classified into three main categories: Dominant, Recessive and X-linked and are inherited (passed on from one generation to another) in a simple pattern according to Mendels Laws. A parent has two copies of a gene at a particular locus, called alleles - one or other of these alleles is transmitted into an individual egg or sperm. This is called the law of segregation, and is why there is a 1 in 2 probability that an offspring will inherit a particular allele of a particular pair of alleles. On this report, you will discover your future offspring possibilities of being affected or being carriers of a monogenic disorder.. ...

A team of scientists has developed a test procedure that significantly increases the prospect of identifying genetic diseases quickly and reliably based on analyses of genes and symptoms.. People with genetic diseases often have to embark on an odyssey from one doctor to the next. Fewer than half of all patients who are suspected of having a genetic disease actually receive a satisfactory diagnosis. Scientists from the Charité - Universitätsmedizin Berlin and the Max Planck Institute for Molecular Genetics have now developed a test procedure that significantly increases the prospect of a diagnosis for affected patients. The procedure is freely available to the relevant medical institutions and can be used with immediate effect.. The first step to the right treatment is an accurate diagnosis - even in untreatable cases, it is invaluable. At the least, it provides the reassurance that the illness is not self-inflicted, says Peter Robinson, one of the developers of the PhenIX diagnostic ...

The NIGMS Human Genetic Cell Repository (NIGMS Repository) is sponsored by the National Institute of General Medical Sciences (NIGMS) and supplies scientists with materials for accelerating cell and biomedical research. The resources available include highly characterized, contaminant-free cell cultures and high quality, well-characterized DNA samples derived from these cultures.

This project sought to identify candidate genes for specific diseases in dogs. Candidate genes are genes known to cause specific diseases in other species. The researchers searched for canine equivalents of three human chromosomes. They identified more than 25 Type I markers (markers that are associated with specific genes). These markers, mapped on the canine genome linkage map, provide valuable information to other scientists looking for the genes causing various heritable diseases in dogs.

We can offer people with asthma a life free of asthma symptoms. That is sure if patient and family follow medical recommendations: taking medicines, avoidance of triggers, quit tobacco.... But we cannot solve the problem that asthma is a heritable disease. We do not have treatments againts altered genes involved in asthma (we still need to know all genes related to asthma !).. Besides, it is a mistake believe asthma will disappear when children become an adult. In fact asthma remain as the most frecuent disease among teenagers and 5% of adults suffer asthma.. Our message is positive but it includes a warning:. children and adolescents with asthma can have a life free of asthma symptoms (that means, a life free of asthma), but really asthma remains, airways inflammation remains, and if family leaves correct asthma cares, asthma symptoms will come back again.. ...

Why is this an OMIA Landmark paper? The authors show that exploiting the availability of large data sets of whole-genome sequences, high-density SNP chip genotypes and extensive recording of phenotype in the context of the large sire families typical of cattle offers an unprecedented opportunity to quickly dissect the genetic architecture of severe dominant conditions in livestock. For each of seven dominant disorders, the strategy involved whole-genome sequencing of just one affected animal, calling variants and filtering them to retain heterozygous polymorphisms that were absent from 1230 control genomes . . . and were predicted to be deleterious to protein function . . . For each of the seven conditions studied, the large number of control genomes enabled [the authors] to decrease the number of candidate causal polymorphisms from millions to only one mutation, each of which was shown to be de novo. The authors also showed how Large half-sib pedigrees allow for the mapping of modifier ...

Here, we noticed that miRNA hits in cancer genes are remarkably higher than other diseases in human. Our observation suggests that UTRs and the transcript length of cancer related genes have a significant contribution in higher susceptibility to miRNA regulation. Moreover, gene duplication, mRNA stability, AREScores and evolutionary rate were likely to have implications for more miRNA targeting on cancer genes. Consequently, the regression analysis have confirmed that the AREScores plays most important role in detecting miRNA targets on disease genes. Interestingly, we observed that epigenetic modifications like CpG methylation and histone modification are less effective than miRNA regulations in controlling the gene expression of cancer genes ...

A Gen Re survey of attitudes to genetic testing found that most people are open to being tested for genetic conditions, believing that it will help them to manage their health better. Many indicated they would have a genetic test if it would give them a better understanding of any health risks they might face, mostly to allow early medical intervention. Some wanted to understand what risks they might pass along to their children while others would have a test if there was a good reason such as family history or existing illness.. Those who didnt want to be tested were reluctant about being burdened with knowledge about diseases about which they believe they could do nothing; they felt a test was unlikely to be useful in the absence of a clinical problem or history of genetic conditions in their relatives.. Their caution is understandable since finding indicators for disease doesnt guarantee disease will develop. Todays genetic markers dont identify highly penetrable disorders with 100% ...

FROM OMMBID CHAPTER 5:. CONCLUSION. The term Homo modificans is used in this chapter to describe a feature of Homo sapiens sapiens; it recognizes that human beings purposefully modify their experience. In the 20th century, one result has been an increase in the heritability of our diseases. Accordingly, the relative importance of genetic causes in human disease is relatively greater than it was in the past. As our ability to recognize and identify those diseases and their causes increases, our ability to treat them successfully should also increase.. General principles for the treatment of genetic disease were established a generation ago. Those principles identify modalities that, in practice, modify the effect of a mutant gene in the affected individual. Although the principles of treatment are reasonably well understood, consistent and successful application of those principles in practice for many of these disorders remains elusive.. The goal of treatment for genetic diseases, in every case, ...

Great News! Analysis of 589,306 genomes identifies individuals resilient to severe Mendelian childhood diseases was published on Nature Biotechnology in 11 April 2016. This paper did a comprehensive screen of 874 genes in 589,306 genomes led to the identification of 13 adults harboring mutations for 8 severe Mendelian conditions, with no reported clinical manifestation of the indicated disease. Findings demonstrate the promise of broadening genetic studies to systematically search for well individuals who are buffering the effects of rare, highly penetrant, deleterious mutations. Also indicate that incomplete penetrance for Mendelian diseases is likely more common than previously believed. The identification of resilient individuals may provide a first step toward uncovering protective genetic variants that could help elucidate the mechanisms of Mendelian diseases and new therapeutic strategies. Almost in the very first time when the paper posted online, a number of hits from major media ...

A review on the current state of knowledge about the incidence, detection, and phenotypic consequences of de novo mutations in human genetic disease.

The Millen Lab has extensive expertise in Mouse Genetics technology. We can assist other investigators in project design, mouse husbandry. As a resource for CIBR we maintain a list of useful mouse strains (ex cre-mice, reporter mice etc) held by various CIBR investigators so we can more productive share reagents. We are particularly focused on advancing mouse ES cell technology. We routinely conduct ES cell gene targeting experiments and generate mouse ES cell chimeras. We can now derive ES cell lines from any genetic background, which is useful to maintain complex compound mutant strains of mice and are using mutant-derived ES cells as sensitized backgrounds for further genetic manipulations. We are also actively working to increase efficiency of ES cell chimera generation, optimize genetic backgrounds for manipulating gene expression and establish innovative RNAi knock-down technologies to model human genetic disease.. ...

There are a number of genetic disease for which persons of Jewish heritage (at least one grandparent) are more likely to be carriers of than the general population. Carriers are healthy individuals, unaffected by the disease for which they carry. If both parents are carriers of a gene mutation for the same condition, there is a 25% chance, with each pregnancy, of having an affected child. These diseases are all serious and can be fatal and or life altering to children born with them ...
