Individual rare diseases may affect only a few people, making them difficult to recognize, diagnose or treat by studying humans alone. Instead, model organisms help to validate genetic associations, understand functional pathways and develop therapeutic interventions for rare diseases. In this Editorial, we point to the key parameters in face, construct, predictive and target validity for accurate disease modelling, with special emphasis on rare disease models. Raising the experimental standards for disease models will enhance successful clinical translation and benefit rare disease research. The full article you can find here.
Atypical hemolytic-uremic syndrome (aHUS) is a rare, potentially lethal systemic disorder, capable of affecting both adults and children, causing thrombotic microangiopathy (TMA) that leads to the formation of thrombus within small blood vessels with multiple organ failure. The pathogenesis of the aHUS is part of a sort of chronic and uncontrolled activation of the complement system by genetic mutation of some proteins usually responsible for its self-regulation. Today, the rapid diagnosis of the disease and the timely start of treatment with eculizumab, improve outcomes of renal failure, stroke and heart attack. Fabry disease is a rare tesaurismosis, X linked, due to the deficiency of the lysosomal enzyme alpha-galactosidase A, necessary for the physiological catabolism of glycosphingolipids. Multisystem clinical manifestations lead to a serious degenerative pathology. The diagnostic suspicion based on anamnesis and careful research of the symptoms and then confirmed by the enzymatic dosage of alpha galactosidase or by molecular analysis, allows the early treatment of the patient with enzyme replacement therapy, guaranteeing the resolution and/or slowing down the evolution of the disease, especially in the brain, heart and kidneys. In this report, we describe the clinical case of a patient who is a carrier of both rare diseases. Everything regarding the case, you can find here.
Fanconi anemia is a rare, cancer-prone disease with mutations in 22 genes. The primary defect results in altered DNA repair mechanisms that fuel a severe proinflammatory condition in the bone marrow, leading to cellular depletion of the hematopoietic system and eventually to bone marrow failure. During the past three decades, a plethora of dysfunctions have been highlighted in the Fanconi anemia phenotype, but recent research allows us to glimpse an even more complex scenario where defective lipid metabolism could have important consequences in hematopoietic stem cell differentiation.
