This natural history study is designed to address the lack of understanding of disease progression. Additionally it will identify clinical and biomarker endpoints for use in future clinical trials.
The purpose of this study is to evaluate the safety and efficacy of RM-004 for Hemoglobin H-Constant Spring disease.
The goal of this hybrid type 1 effectiveness-implementation study is to evaluate and compare different ways of delivering genetic research results to participants. The main questions the study aims to answer are: - Is sharing actionable genetic research results with participants through a multimedia patient-informed eHealth intervention (e.g. patient portal) no worse than sharing results by telephone or videoconference with a genetic counselor? - Will research participants access an eHealth educational intervention or chatbot education to learn about research results being offered and the option to decline learning their individual research results and how frequently participants choose to decline actionable research results? - Who benefits less and more from digital intervention with return of actionable research results and what barriers exist to using these tools for return of research results outside this study? Participants in the biobank will be offered digital tools to learn about research results being offered and the option to decline receiving these results. Those who don't decline and have an actionable result will be randomly assigned to receive their results with a genetic counselor or through an eHealth portal. Participants will complete surveys before and after receipt of results to understand patient experiences with these methods of education and return of results to determine if digital tools can be used to help ensure more patients get access to research results which could impact their health.
Cerebellar ataxia is a pathology linked to the lesion of the cerebellum or the afferent and/or efferent cerebellar pathways. The aetiology can be an acquired cerebral lesion, following a chemical poisoning or a genetic degenerative lesion (for example : Friedreich's ataxia, spinocerebellar ataxias, etc.). As reported by the latest estimate available, genetic degenerative cerebellar ataxias affect approximately 6,000 patients in France (Orpha.net). Symptoms suffered by ataxic patients are : problems and gait disorders along with difficulties in coordination resulting in ataxia, uncoordinated movements. These symptoms cause a decrease in the quality of life on patients with spinocerebellar ataxia. The symptoms improvement linked to the cerebellar syndrome is based on rehabilitation that can be supplemented by use of technical aids. Current scientific knowledge confirms that intensive rehabilitation by physiotherapy and occupational therapy in patients with degenerative ataxias improves cerebellar symptoms. Nevertheless, the choice rehabilitation technique stay at the appreciation of the therapist. From the observation, the investigators have designed an intensive multidisciplinary rehabilitation program, called PAMPERO, with partner patients member of two genetic degenerative ataxia patient organisations. This 5-weeks program has been used in clinic during 3 years on 28 patients. It appears to be the only one in France. The preliminary results show a positive effect on ataxia symptom. Nevertheless, the duration of the benefice over time and the effect on the quality of life stay unknown. However, the quality of life is mainly affected by the participation restriction due to the risk of falling. The most frequent complaint from partner patient is the diminution of the social interaction resulting of the incapacity to move without risk. The present protocol aimed at evaluating the Rehabilitation Program in collaboration with partner patient on the symptom intensity, activity and quality of life on genetic and degenerative ataxia. This PAMPERO program's effect will be assessed by comparing the difference of Intensity of symptom measured by to Scale for the Assessment and Rating of Ataxia (SARA) at inclusion and 3 months after the end of rehabilitation.
Genomic methods can significantly contribute to all facets of precision medicine, from diagnosis to prevention, therapeutic intervention, and management of acute and chronic illnesses. DNA based methods are already having a considerable impact across healthcare in fields that include: public health, infectious disease monitoring, acute and chronic disease, pharmacogenomics, prenatal testing and diagnosis, and therapeutic development. In this proposal, investigators are focusing on the application of genomic methods in precision medicine - specifically on rapid whole-genome sequencing of parents and children (i.e. a trio) for the identification of diseases that have genetic components. Goals Primary goal: is to provide safe rapid whole genome sequencing to Neonatal Intensive Care Unit/Pediatric Intensive Care Unit patients. Secondary goals: 1) Although several groups globally are implementing rapid sequencing of rare disease, these are predominantly in the research space, with many unanswered questions regarding the best way to implement them into a national healthcare system. Each country and their healthcare systems are unique, and valuable knowledge will be gained by implementing this process within a New Zealand context. As part of this the study will measure the impact on the individuals and families. 2) to expand the research team's understanding of non-coding disease-causing variants and methylation changes that contribute to severe disease in early life. Primary Aims 1. To incorporate long-read RNA sequencing data into the diagnostic rapid Whole Genome Sequencing pipeline to provide a direct measure of the functional outcome of the variants of clinical concern. 2. To measure the clinical utility of analysing non-coding variants in the diagnosis of critically ill children who do not have pathogenic, likely pathogenic, or variants of unknown significance for mendelian disorders. 3. To identify, in a real-world setting within the New Zealand health-care system, the clinical and economic effects of deploying rapid Whole Genome Sequencing-informed rapid precision medicine for critically ill children.
The project is focused on the detailed study of structural genomic variants (SVs). Such genetic mutations are in fact alterations in the DNA molecule structure and include copy number variants, inversions and translocations. A single event may affect many genes as well as regulatory regions and the specific phenotypic consequences will depend on the location, genetic content and type of SV. Many times, the specific disease-causing mechanism is not known. Here, we plan to study the molecular genetic behavior of structural variants as well as the underlying mutational mechanisms involved. First, we will use genome sequencing to pinpoint the chromosomal breakpoints at the nucleotide level, characterize the genomic architecture at the breakpoints and study the relationship between structural variants and SNVs. Second, we will study how structural variants impact gene expression. Finally, we will functionally explore the disease mechanisms in vivo using zebrafish and in vitro using primary patient cells and induced pluripotent stem cells. Our studies will focus on the origin, structure and impact of structural variation on human disease. The results will directly lead to a higher mutation detection rate in genetic diagnostics. Through a better understanding of disease mechanisms our findings will also assist in the development of novel biomarkers and therapeutic strategies for patients with rare genetic disorders.
Sudden infant death syndrome (SIDS) is a disease of an infant under one year of age, whose sudden death occurred unexpectedly, which the cause of death cannot be determined despite macro-autopsy, and toxicological, pathological and microbiological examinations. It is most common in babies aged 2-4 months. Although it cannot be attributed to a single cause, it is suggested that apnea/airway obstruction, abuse, developmental disorders, exposure to cigarette smoke, infections, toxic gases, metabolic diseases, and cardiac problems cause SIDS. It is known that genetic studies on SIDS are few and the literature reported so far is insufficient. On the other hand, as a result of rapid developments in genetic diagnosis methods, various genes associated with SIDS have been reported in recent studies. Most of the studies conducted include genetic studies aimed at investigating specific disease groups in SIDS. Although there are few studies on comprehensive investigation of genetic causes, potentially causative variants have been identified in 20% of cases where whole exome sequencing has been performed. In a study including perinatal deaths in which the reports of the Forensic Medicine Institute in our country were examined, 4% of the cases were reported as infant deaths of unknown cause. However, this study is only autopsy data and does not include metabolic and genetic examinations. For this reason, as far as we know, there is no information about the incidence of SIDS in our country. Based on this information, in our research, in the province of Ankara, the deaths of children under one year of age who died unexpectedly and suddenly were examined, autopsied, and toxicological examinations were performed on internal organ samples and body fluids taken during the autopsy by the Ankara Group Presidency of the Forensic Medicine Institute between 2018 and 2023. Genetic investigation of hereditary diseases that may lead to death of cases whose cause of death cannot be explained despite pathological and microbiological examinations will be carried out by the Whole Exome Sequencing (WES) method. The project will be carried out by researchers at Ankara University Faculty of Medicine and Forensic Medicine Institute Ankara Group Presidency. This research project was planned as a prospective, descriptive, open uncontrolled study. The duration of the project is foreseen as 12 months. Approval for our research was received from Ankara University
Neurogenetic diseases (NGD) represent rare and hereditary forms of neurological diseases. The goal of CNGD is to create a one-window approach for NGDs, to facilitate and accelerate participation in research projects through deep phenotyping and the availability of low-cost biological samples for research teams. It is positioned as a true hub allowing new connections between clinical and basic research teams and ultimately as an incubator for translational projects for NGDs, in order to be able to initiate therapeutic trials, the ultimate objective of clinical and translational research.
Infertile women attending for PGT at the Centre of Assisted Reproduction and Embryology, Queen Mary Hospital and Kwong Wah Hospital will be recruited during ovarian stimulation for IVF. Subsequently, they will be randomly assigned on the day of oocyte retrieval by a laboratory staff into one of the following two groups in a 1:1 ratio : (1) the microfluidic chip group and (2) the density gradient centrifugation group for sperm preparation and subsequent use in fertilization. Other IVF procedures will be the same as the standard practice of the Centre. Both women and clinicians will be blinded from the group allocation i.e. a double blind study.
This monocentric retrospective observational study aims to evaluate the efficacy of pre-implantation genetic testing for monogenic diseases (PGT-M). The effectiveness will be assessed in terms of live birth rate (LBR), cumulative live birth rate (CLBR) per couple, and abortion rate (AR). Considering how many cycles the participants have undergone to achieve a viable blastocyst. The secondary objective is to evaluate the incidence of aneuploidy in unaffected embryos, in order to understand the need for pre-implantation genetic testing for aneuploidy (PGT-A)in addition to PGT-M.
