Psychiatric Characteristics Across Individuals With PTEN Mutations

Area of Science:

• Neurodevelopmental disorders
• Genetics and behavior

Background:

• Germline heterozygous PTEN mutations are linked to autism spectrum disorder (ASD) and behavioral problems.
• Understanding specific psychiatric comorbidities in PTEN mutation-associated ASD compared to idiopathic ASD remains limited.

Purpose of the Study:

• To compare psychiatric characteristics in children and adolescents with PTEN mutations with and without ASD, and in those with ASD and macrocephaly but no PTEN mutation.
• To identify specific behavioral profiles associated with PTEN mutations and ASD.

Main Methods:

• Cross-measure approach comparing three groups: PTEN-ASD, PTEN-No ASD, and macro-ASD.
• Utilized Child Behavior Checklist (CBCL) and Aberrant Behavior Checklist (ABC) for assessment.

Main Results:

• Significant group differences observed across CBCL and ABC scores.
• ASD groups (PTEN-ASD and macro-ASD) exhibited more behavioral symptoms than the PTEN-No ASD group.
• No significant differences between PTEN-ASD and macro-ASD, though macro-ASD trended higher in aggression.

Conclusions:

• Evidence supports distinct behavioral profiles in PTEN-No ASD, PTEN-ASD, and macro-ASD groups.
• Highlights the importance of early identification of behavioral vulnerabilities in individuals with PTEN mutations for timely intervention.
