Filter by:Birth defects are relatively common, occurring in 1 in 40 live born babies. They can be single, or multiple. They may occur as part of multiple malformation syndromes, often in association with growth disturbance or intellectual disability. Over 7000 rare syndromes have been identified. Thus, though they are rare they are collectively important. Understanding how a multiple malformation syndrome came about, defining what investigations and health surveillance is needed for affected children and identifying whether there is a treatment is very important for parents and professionals caring for affected children and also for genetic counselling of their extended families, since the majority will have a genetic basis. Diagnosis of these rare disorders is therefore important,but as many syndromes are rare this can be extremely difficult and requires specialist knowledge, many investigations and many hospital appointments. This study aims to determine whether using face-recognition software can improve diagnosis of rare syndromes when used in addition to current routine practice.
No additional risk factors have been identified in patients with Inherited Metabolic Diseases (IMD) for contracting or presenting complications of COVID-19 compared to the general population. Yet, IMD patients have cell/tissue alterations that could constitute a potential direct or indirect target for the virus. We do not know the impact of this infection on patients suffering from MHM, nor the possible effect of specific treatment of MHM on the evolution of COVID-19. This study will collect French IMD patients having or having had COVID-19 infection. The main objective is to estimate among IMD patients contracting COVID-19 the frequency of disease aggravation or metabolic decompensation. The secondary objectives will be : a. to evaluate the incidence of COVID-19 diagnosed in a given group of IMD when the number of patients with this IMD is known (Urea Cycle Deficiency, Gaucher Disease). b. to evaluate the impact of IMD on the and severity of COVID-19 infection
The goal of this study is to identify and characterize novel non-coding and splicing variants that may contribute to genetic disorders. We will particularly focus on patients with a diagnosed genetic disorder that has inconclusive genetic findings.
The aim of this study is to demonstrate that a new protein substitute is acceptable and well tolerated in children with PKU.

A fetal hydrops, also called a fetal anasarca, is the buildup of fluid in the serosa and / or fetal subcutaneous tissue. The diagnosis is made by ultrasound, possibly from the first trimester of pregnancy. The etiologies of hydrops can be immune or non-immune. The historically classic immune causes are linked to fetal-maternal alloimmunizations in erythrocyte blood groups. The implementation of systematic prevention of these anti rhesus immunizations since the 1970s has significantly reduced the incidence of immune hydrops Non-immune hydrops (NIH) now represent 90% of fetal hydrops. Known causes of NIH can be classified in several ways depending on the mechanism or organ involved. The prognosis for NIH is closely linked to the cause. Fetal anemia due to maternal-fetal infections can heal spontaneously or give rise to in utero transfusions. Cardiac rhythm abnormalities are accessible to medical treatment. Chylothorax compressions may benefit from in utero drainage, but chromosomal or metabolic causes cannot benefit from antenatal care. The term of pregnancy in which the hydrops is discovered also has an impact on survival, which however remains poor. In France, certain pathologies can be considered as particularly serious without the possibility of treatment and give rise to a request for medical termination of pregnancy. This possibility is subject to acceptance by two practitioners who are members of a multidisciplinary prenatal diagnostic center (CPDPN). This preliminary multidisciplinary reflection participates in the development of prenatal counseling with the greatest precision in diagnostic hypotheses. This prenatal advice is essential for a couple on the decision to make a pregnancy in progress but also for future pregnancies, given the 25% risk of recurrence due to the autosomal recessive mode of transmission. Thus the current screening strategy for inherited metabolic diseases on amniotic fluid is fragmented. The resulting subdiagnosis explains the objective of the study of using the new high throughput sequencing techniques (NGS) in this indication. This approach should make it possible to reduce the number of cases classified as idiopathic, to allow the parents concerned to receive suitable genetic counseling with a view to new pregnancies, and to refine the knowledge of the prenatal epidemiology of these pathologies.
lnborn errors of metabolism (IEM) are a heterogeneous group of rare, sometimes debilitating or even fatal diseases . In IEM, both definition and assessment of meaningful outcome parameters is often extremely difficult resulting in a limited body of evidence. Limited evidence results in weak recommendations which are perceived as unbinding and thus sustains heterogeneous study designs, choice of outcomes and interventions again producing non-uniform data. The goal of the current study is to identify and select reliable instruments, that measure patients' and their parents' perception about relevant (social, emotional, cognitive and physical) aspects in their lives. This set of instruments will secure the comparability of future research findings. Furthermore this instruments will improve the screening of paediatric IEM patients regarding their need for additional (psychosocial or consultative) support in daily hospital routine.
Researchers are trying to determine the efficacy of a global metabolomic approach in testing for and diagnosing inborn errors of metabolism as opposed to traditional testing methods.
International, multicenter, observational, longitudinal study to identify or monitor Inborn Error of Metabolism disease biomarkers and to explore the clinical robustness, specificity, and long-term variability of these biomarkers
Human induced pluripotent stem cells (iPSCs), are reprogrammed from somatic cells that can self-renew indefinitely and produce different types of cells. They provide human model cell lines for orphan drug development. It is the goal of this study to define new cellular disease models for Inborn Erors of Metabolism, as enabling tools for both drug discovery and development.
