Great question! 2024 brought significant advances in autism genetics and personalized care. Researchers identified 230+ new genes linked to autism (Genedx), and genetic testing now explains ~20% of cases, with potential to reach 50% through advanced sequencing (Autism Speaks). A landmark Nature Genetics study (July 2025) categorized autism into 4 biologically distinct subtypes based on genes and traits, paving the way for precision therapies (Princeton Engineering). Current guidelines recommend genetic testing for all diagnosed individuals, as it can guide personalized treatment plans (medRxiv). The Autism Science Foundation's 2024 review highlights how these findings are transforming clinical practice. Would you like details on any specific aspect?
