Study Identifies Four Autism Subtypes Tied to Genetic Traits in Children

Quick Summary:

• Researchers Divide Autism into Four Subtypes: A study analyzing data from 5,392 autistic children identified four autism subtypes by linking behavioral traits with genetic profiles.
• Distinct Challenges in Each Subtype:

– Social and Behavioral challenges (37%): Major difficulties with social interaction, restrictive behaviors, attention issues but no developmental delays.
– Mixed ASD with Developmental Delay (19%): Varied social challenges and repetitive behaviors alongside developmental delays.
– Moderate Challenges (34%): Fewer overall difficulties compared to other autistic groups; no developmental delays.
– Broadly Affected (10%): Severe difficulties across multiple domains including significant delays in development.

• The subtypes had distinct genetic differences and were replicated successfully in a smaller group of participants.
• Researchers note the sample skewed toward white participants,limiting broader applicability of results. Additional data may refine subtype definitions further.
