Introduction: Monogenic obesity is caused by a unique genetic dysfunction, often appears in childhood, and can be accompanied by neuroendocrine, skeletal, developmental, and behavioral disorders, among other manifestations. Some variants in the SH2B1 gene have been suggested as strong candidates for the development of autosomal dominant obesity.
Case Presentation: We describe here the clinical response after 1 year of setmelanotide treatment in a 22-year-old patient with an SH2B1 variant.
