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.\n\nThe 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.",[80,81,82,83,84,85,86,87,88,89,90,91,92,93,94],"Invasive PreNatal Diagnosis in a Context of Family History of Single-gene Disorders, Including","Sickle Cell Disease","Cystic Fibrosis","Fragile X Syndrome","Proximal Spinal Muscular Atrophy","Myotonic Dystrophy","Muscular Dystrophy, Duchenne","Muscular Dystrophy, Becker","Neurofibromatosis-Noonan Syndrome","Huntington Disease","Hemophilia A","Hemophilia B","MODY2 Diabetes","X-Linked Hydrocephalus","Autosomal Recessive Polycystic Kidney Disease",[96,97,98,99,100,101,102,103,104,105,106,107,108],"Gene HBB","Gene CFTR","Gene FMR1","Gene SMN1","Gene DMPK","Gene DMD","Gene NF1","Gene HTT","Gene F8","Gene F9","Gene GCK","Gene L1CAM","Gene PKHD1","2026-04-20",{"date":111,"type":112},"2026-04-23","ACTUAL",{"date":114,"type":112},"2024-10-23",{"date":116,"type":76},"2027-05",{"name":5,"class":6},1]
