11q22.2q22.3 microdeletion syndrome

11q22.2q22.3 microdeletion syndrome is a rare genetic condition caused by a small missing piece of chromosome 11, in a region called 11q22.2 to 11q22.3. This deletion means that several genes in that area are either missing or not working properly, which can affect how the brain, body, and organs develop. The condition is sometimes referred to simply as a chromosome 11q deletion or 11q22 microdeletion. People with this syndrome often show signs from birth or early childhood. Common features include intellectual disability, delayed speech and language development, and learning difficulties. Some individuals also have physical differences such as unusual facial features, low muscle tone (called hypotonia), and problems with growth. Heart defects and behavioral challenges, including features similar to autism spectrum disorder, have also been reported in some cases. There is currently no cure for 11q22.2q22.3 microdeletion syndrome. Treatment focuses on managing symptoms and supporting development. This usually involves a team of specialists and therapies such as speech therapy, occupational therapy, and physical therapy. Early intervention is very important and can make a meaningful difference in a child's development and quality of life.
