Home / Glossary Down Syndrome (Trisomy 21) By Motherly Editors April 2, 2024 Rectangle Definition Down Syndrome, also referred to as Trisomy 21, is a genetic condition resulting from the presence of an extra 21st chromosome in the body’s cells, often characterized by distinct physical features and cognitive impairment. This additional genetic material alters the course of development and causes the features associated with Down Syndrome. Characteristics could include speech and language delays, mental retardation, growth issues, and health problems. Key Takeaways Down Syndrome, also known as Trisomy 21, is a condition where a person is born with an extra copy of chromosome 21. This extra chromosome affects mental and physical development, resulting in symptoms such as mild to moderate intellectual difficulties and certain physical characteristics. Every mother of a child with Down Syndrome should know that it’s not anyone’s fault. It doesn’t happen because of anything the parents did or didn’t do. The cause of the extra copy of the chromosome is still unknown, but it’s unlikely to be anything the parents could have prevented. Children with Down Syndrome can lead fulfilling lives, but they often need some level of support. They typically require ongoing medical care from a team of specialists, and they may also need occupational, speech, and physical therapy. Most importantly, they need love, understanding, and encouragement from their family, school, and community. Importance The term “Down Syndrome” or “Trisomy 21” is imperative in motherhood as it pertains to a common genetic disorder that a child may be born with, impacting a mother’s childrearing experience significantly. Trisomy 21 indicates that there is an extra copy of chromosome 21, hence the term “trisomy.” This condition affects a child’s physical features, growth, and cognitive development, often leading to intellectual disability and certain medical conditions. Awareness of this term is essential for mothers as early detection, through prenatal testing, can allow for better preparedness and education on how to provide the necessary care and support. Therefore, understanding the term can lead to better management, creating a more nurturing environment for the child to thrive in. Explanation Down Syndrome, medically known as Trisomy 21, is a term that refers to a chromosomal condition where an individual is born with an extra 21st chromosome. Instead of the usual pair, a person with Down Syndrome has three copies of this chromosome. This additional genetic material alters development, leading to the characteristics associated with Down Syndrome. The term has enormous importance as it allows medical professionals, researchers and caretakers to identify and assess the particular health and developmental challenges individuals with this condition may face. The application of the term “Down Syndrome” gives a framework for understanding and approaching the special needs of these individuals. It aids in early identification, thus enabling timely intervention and management that significantly improves their quality of life. The term provides a basis for research and understanding the condition better, thereby leading to advancements in treatment and care. Primarily, it’s used as a tool to foster awareness, acceptance, and inclusion of people with Down Syndrome in general society. Comprehensive support services and policies rely on the use of this term to design strategies that promote the overall wellbeing and integration of individuals with Down Syndrome. Examples of Down Syndrome (Trisomy 21) Example 1: Sarah, a 34-year-old woman, gives birth to her first child, a girl. During her pregnancy, Sarah opted for prenatal testing, which revealed that her child had an extra chromosomal material on chromosome Her daughter, now confirmed to have Down Syndrome, is receiving therapy and special education services to aid her developmental growth. Example 2: David and Katie have a 7-year-old son, Ben, who has Down Syndrome. He was diagnosed shortly after birth following a genetic test. Ben attends a local school for children with special needs, where he receives tailored education to his needs. Also, he attends weekly physical therapy sessions to improve his movement skills. Despite his diagnosing disorder, Ben’s parents strive to ensure that his life is filled with love, joy, and opportunity just like any other child. Example 3: Susan, an aged woman, recounts the day her son was born with Down Syndrome 40 years ago. At that time, the understanding and resources for Down Syndrome were quite limited. Despite the hardships, Susan dedicated her life to raising her son with utmost love and care. Now, her son leads an independent life with a job at a local library and lives in an assisted living facility. FAQ: Down Syndrome (Trisomy 21) What is Down Syndrome (Trisomy 21)? Down Syndrome, also known as Trisomy 21, is a genetic disorder caused by the presence of all or part of a third copy of chromosome 21. It is usually associated with physical growth delays, mild to moderate intellectual disability, and characteristic facial features. How is Down Syndrome diagnosed? Down Syndrome is usually identified at birth by the presence of certain physical traits: low muscle tone, a single deep crease across the palm of the hand, a slightly flattened facial profile and an upward slant to the eyes. The diagnosis must be confirmed by a chromosome study (karyotype). Can Down Syndrome be prevented or cured? There is no cure for Down Syndrome, but there is a wide spectrum of support and services available to individuals with Down Syndrome and their families to help them lead healthy and fulfilling lives. Prevention of Trisomy 21 is not currently possible. What are some complications associated with Down Syndrome? Individuals with Down Syndrome may have a variety of complications, some of which become more prominent as they get older. These complications may include heart defects, gastrointestinal defects, immune disorders, sleep apnea, obesity, mental health conditions like depression and anxiety, and early-onset Alzheimer’s disease. What support is there for parents with a Down Syndrome child? There are numerous resources available for parents of children with Down Syndrome. From early intervention programs and therapy to schooling and community support, many tools are available to help. Parent networks also provide a great way to connect with others facing similar challenges.
