Wilson-Turner syndrome

Wilson-Turner syndrome (also known as Wilson-Turner mental retardation syndrome) is a rare X-linked intellectual disability syndrome first described in 1991 in a large Australian family. The condition primarily affects males and is characterized by intellectual disability, obesity, gynecomastia (enlarged breast tissue in males), speech difficulties, emotional lability, tapering fingers, and small feet. Affected individuals typically have a characteristic facial appearance and may exhibit short stature. The syndrome affects multiple body systems including the central nervous system (cognitive and behavioral function), the endocrine system (contributing to obesity and gynecomastia), and musculoskeletal development. The genetic basis of Wilson-Turner syndrome has been mapped to the Xp21.1-q22 region of the X chromosome. Carrier females may show mild features of the condition, such as mild intellectual disability or obesity, but are generally less severely affected than males. The degree of intellectual disability ranges from mild to moderate in most reported cases. There is currently no specific cure or targeted therapy for Wilson-Turner syndrome. Management is supportive and symptomatic, focusing on educational support for intellectual disability, speech therapy for language difficulties, behavioral interventions for emotional lability, and endocrine management for obesity and gynecomastia when needed. Regular monitoring of growth, development, and metabolic parameters is recommended. Genetic counseling is important for affected families to understand recurrence risks and carrier status.
