Autism spectrum disorder profile in neurofibromatosis type I.

Doctors looked at kids who have both neurofibromatosis type 1 (NF1) and autism.

They wanted to see if these kids act the same way as kids with autism alone.

The team watched eye contact, language, and repetitive behaviors in a small group.

The kids looked autistic, but their signs were softer.

They kept better eye contact, spoke more words, and repeated fewer actions.

In short, NF1 plus autism is its own flavor of autism.

McCauley et al. (2018) did the same mapping in ADNP syndrome.

That group shows the opposite pattern: milder social issues yet more hand-flapping.

Together the two papers prove that genes shape which autism signs stand out.

McGhee et al. (2025) went further in Noonan syndrome.

They linked a single gene change (PTPN11) to how bad the repetitive behaviors get.

Their work extends the NF1 idea: once you know the syndrome, you can predict the profile.

When you see a client with NF1, do not assume severe stimming or language delay.

Write goals that push social use of their already-good words.

Watch for attention issues shown by Gilboa et al. (2011) and plan short, clear tasks.

Matching the program to the syndrome gives faster progress and less frustration.
