Create a scientific poster summary graphic based on a case report of Marfan syndrome with X trisomy and FBN1 and SDHB mutations. The central figure should represent a patient with clear callouts for key genetic findings: FBN1 mutation, SDHB mutation, and X trisomy. Include main clinical features such as myopia, connective tissue disorder, and risk of tumors. Also show treatment and prognosis details including posterior scleral reinforcement and improved visual acuity. Use a clean, professional style with a solid white background and bold black text for all labels. The design should be suitable for medical professionals and students. Reference the provided case report image for context.emoji
