Question: What are the genetic changes related to 16p11.2 deletion syndrome ?
Answer: People with 16p11.2 deletion syndrome are missing a sequence of about 600,000 DNA building blocks (base pairs), also written as 600 kilobases (kb), at position p11.2 on chromosome 16. This deletion affects one of the two copies of chromosome 16 in each cell. The 600 kb region contains more than 25 genes, and in many cases little is known about their function. Researchers are working to determine how the missing genes contribute to the features of 16p11.2 deletion syndrome.
