Filter by:Cell-free fetal DNA (cffDNA) is present in the maternal blood from the early first trimester of gestation and makes up 5%-20% of the total circulating cell-free DNA (cfDNA) in maternal plasma. Its presence in maternal plasma has allowed development of noninvasive prenatal diagnosis for single-gene disorders (SGD-NIPD). This can be performed from 9 weeks of amenorrhea and offers an early, safe and accurate definitive diagnosis without the miscarriage risk associated with invasive procedures. One of the major difficulties is distinguishing fetal genotype in the high background of maternal cfDNA, which leads to several technical and analytical challenges. Besides, unlike noninvasive prenatal testing for aneuploidy, NIPD for monogenic diseases represent a smaller market opportunity, and many cases must be provided on a bespoke, patient- or disease-specific basis. As a result, implementation of SGD-NIPD remained sparse, with most testing being delivered in a research setting. The present project aims to take advantage of the unique French collaborative network to make SGD-NIPD possible for theoretically any monogenic disorder and any family.
Myotonic dystrophy type 1 (DM1) is a rare genetic disease that affects about 1 in 2100 people. Patients diagnosed with DM1 present with many symptoms, however, their muscles are mainly affected. DM1 patients experience a gradual loss of muscle, followed by an increase in body fat percentage, which makes them weaker, resulting in difficulties to perform activities of daily living, such as climbing stairs, and understandably, this affects their quality of life. DM1 currently does not have a cure. Therefore, it is very important to find ways in which we can help DM1 patients to improve their symptoms, and hopefully, improve their quality of life, and possibly improve disease prognosis. Exercise is known to improve muscle quality and function. In addition, we hypothesize that a multi-ingredient supplement (MIS) for muscle health and antioxidants for fat loss, might show improved benefits on top of exercise. Therefore, we will investigate the effects of 16-week home-based concurrent training, with MIS or placebo, on body composition, and functional measures. Lastly, we will investigate muscle adaptations in DM1 and following study intervention
The study team hypothesize that non-diabetic patients with Myotonic dystrophy type I (DM1) will improve their symptoms, especially their motor deficit which is the main feature of the disease, because of the splicing defect correction by metformin. The primary objective of the study is to evaluate the efficacy of metformin vs placebo, on the improvement of muscle function in patients with DM1 compared to its placebo. As the secondary objectives, the study aims: - To evaluate the safety of metformin on patient with DM1. - To evaluate the efficacy of metformin vs placebo on: 1. The hand-grip strength; 2. The thumb-index pinch strength; 3. The locomotor function; 4. The respiratory function; 5. The cardiac function; 6. The quality of life; 7. The daily and social activity.
