CNVs, or copy number variations, are changes in the number of copies of certain parts of a person’s DNA. These changes can lead to differences in how the body develops and functions, sometimes causing conditions like autism or intellectual disabilities.
How do CNVs impact a child's development?
CNVs can cause developmental delays, learning challenges, speech issues, and even physical symptoms or behavioral changes in kids.
Are there treatments available for kids with CNVs?
Yes, treatments range from genetic counseling and supportive therapies to medications and specialized educational support.
How can tools like visual schedules help kids with CNVs?
Visual schedules, like Goally, guide kids through daily tasks, fostering independence and helping with routines which can be particularly helpful for children affected by CNVs.
Copy number variations (CNVs) are structural variations in the human genome where sections of DNA are duplicated or deleted, resulting in an abnormal number of copies of one or more genes. These variations can range in size from a few hundred base pairs to several megabases and may contribute to the development of various neurodevelopmental disorders, such as autism spectrum disorder (ASD) and intellectual disability. Studies suggest that CNVs are found in approximately 10-20% of individuals with ASD or ID.
Children with copy number variations (CNVs) face unique challenges that can affect their development and learning. To support these children effectively, a multifaceted approach is essential. Here are some key interventions that can make a significant difference in their lives:
The prognosis for children with CNVs can vary widely based on the specific genetic changes and the individual child. However, with tailored support and appropriate interventions, many of these children can lead fulfilling lives and reach their personal goals.
