What is 16p11.2 distal
deletion syndrome?

16p11.2 distal deletion syndrome is rare, described in fewer than 40 people to date. Doctors and scientists have just recently begun to study it. 16p11.2 distal deletion syndrome can affect communication, social, and learning skills. People with 16p11.2 distal deletion syndrome may have:

  • Obesity
  • Developmental delay or intellectual disability
  • Speech delay

How many people have 16p11.2 distal deletion syndrome?

As of 2020, scientists had described fewer than 40 people who have 16p11.2 distal deletion syndrome in the medical literature. The first case was found in 2010. There are likely many more undiagnosed people who have the syndrome. Scientists expect to find more people who have the syndrome as access to genetic testing improves.

People with 16p11.2 distal deletions are missing a section of one of their two chromosome 16s.

People with 16p11.2 distal deletions appear to have an increased risk for development problems, which may or may not include autism. The information available about 16p11.2 distal deletions is limited, and families and doctors share a critical need for more information. Simons Searchlight participants help doctors and scientists find new information about the effects of 16p11.2 distal deletions.

Learning

6 out of 6 had a developmental delay or intellectual disability.

Behavior

2 out of 6 had autism.
2 out of 6 had behavior issues or attention deficit hyperactivity disorder, also called ADHD.

Growth

4 out of 6 people were overweight, in the 95th percentile or above for body mass index, a measure of weight versus height.

Research Article Summaries

Below, we have summarized research articles about 16p11.2 Distal Deletion. We hope you find this information helpful.

The information available about 16p11.2 Distal Deletion is limited, and families and doctors share a critical need for more information. As we learn more from children who have a change in this gene, we expect this list of resources and information to grow.
