Biomarkers are measures of what is happening inside the body, shown by the results of laboratory, imaging or other tests.\n\nBiomarkers can help doctors and scientists diagnose diseases and health conditions, monitor responses to treatment and see how a person's disease or health condition changes over time.\n\nThe goal of this observational and laboratory study is to develop clinical, neurophysiology and molecular biomarkers in RAI1-related disorders. The main question\\[s\\] it aims to answer are:\n\n* to characterize the disease features more precisely and analyze the differentiating and overlapping features of RAI1-related disorders (Smith-Magenis syndrome and Potocki-Lupski Syndrome)\n* to identify clinical, neurophysiology, and laboratory biomarkers that differentiate RAI1-related disorders one from another.\n\nParticipants will have to complete:\n\n* a clinical examination\n* a blood draw\n* a skin biopsy (optional)\n* a sleep study\n\nResearchers will compare patients' blood to control group's blood for biomarker studies.",[26],"RAI1 Gene 17P11.2 Deletion+Duplication",[28,29,30,31],"Smith-Magenis syndrome (SMS)","Potocki-Lupski Syndrome (PTLS)","RAI1-related disorders","Retinoic Acid-Induced 1-related disorders","RECRUITING","2026-06-02",{"date":35,"type":36},"2026-06-03","ACTUAL",{"date":38,"type":36},"2024-03-13",{"date":40,"type":22},"2027-05",{"name":42,"class":43},"Baylor College of Medicine","OTHER"]
