In a 16p11.2 deletion mouse model, lineage tracing across five brain regions shows prominent striatal changes, with D1 striosome SPNs exhibiting the strongest molecular disruption in ASD.
- Why it matters: Rare ASD variants leave unclear which subcortical cell types integrate regulatory signals, and where convergent molecular programs emerge to guide mechanism-focused studies.
- What they did: Single-nucleus multi-omics of human putamen from ASD and neurotypical donors mapped transcriptional shifts concentrated in D1 striosome SPNs and linked astrocyte synapse-support programs; chromatin-expression network analysis highlighted EGR1 and EGR3 with reduced activity, and organoid deletion of EGR1 or EGR3 yielded partially overlapping transcriptional effects.
- The result: The striatum is established as a molecular convergence site in ASD, and the multi-omic dataset enables targeted dissection of subcortical mechanisms.
