PMID 37130201WHAT IT FOUND
Parents reported more attention, executive function, social, and aggression difficulties in children with Noonan syndrome.
ADHD and oppositional symptoms were common, but objective cognitive differences did not persist after accounting for IQ.
Key findings
01Children with Noonan syndrome had higher parent-reported attention, executive function, social, and aggression symptoms than typically developing children.
02ADHD and oppositional symptoms were common: 20 of 42 children met ADHD criteria, 7 had subthreshold ADHD symptoms, and 8 met ODD criteria, with 6 more showing subthreshold ODD symptoms.
03No child met full ASD criteria, but 15 of 42 children had reported friendship difficulties and 4 of 42 had restricted or repetitive behaviors.

What it does not show
Families volunteered to participate, so the sample may have included children with more noticeable difficulties. Some analyses included fewer children because data were missing. The study did not use standard diagnostic assessments for ASD. Objective cognitive test differences did not remain significant after accounting for IQ. The SOS1 subgroup was small.
Declared interests
The supplied metadata lists NIH extramural and non-U.S. government research support; no author conflict statement is provided.
The easy way to misread this
Do not read the parent-reported social difficulties as a diagnosis of autism. No child met full ASD criteria, and the study did not use standard diagnostic assessments.
