Trisomy 13, also known as Patau syndrome, is a genetic disorder caused by the presence of an extra copy of chromosome 13 in a person's cells. This condition can lead to severe intellectual disability and physical abnormalities, including heart defects, cleft lip or palate, and problems with the eyes and brain. The symptoms of Trisomy 13 can vary widely, but many affected individuals face significant health challenges. Unfortunately, the prognosis is often poor, with many infants not surviving beyond their first year of life. Early diagnosis and supportive care are essential for managing the condition.
