Q. A concerned mother brings her 1-year-old boy to the pediatric clinic. She mentions that he seemed relatively normal at birth, but she began noticing distinct changes in his facial features over the past few months. Examination reveals coarse facial features, including a wide nasal bridge and a flattened midface. Furthermore, the child displays hepatosplenomegaly and corneal clouding. Upon reviewing his medical history, it's noted that he had a surgical repair for an umbilical hernia and has been frequently hospitalized for recurrent respiratory infections with chronic nasal discharge. Radiological findings suggest specific skeletal abnormalities consistent with dysostosis multiplex, and developmental assessments indicate a delay in reaching milestones. What is the diagnosis?
