The discovery could help clinicians diagnose children who carry mutations in the gene, called SCN2A, and gauge their responses to potential therapies.

In this edition of Null and Noteworthy, scientists find little to be excited about in research on biomarkers for neurodevelopmental conditions.

A new atlas reveals how the structural shake-ups within a cell’s genome differ by cell type and brain region over time.

Null and replicated results in this month’s newsletter tackle aging, a purported pathway for oxytocin’s effects on autistic people, and a possible autism biomarker.

The signaling molecule’s social role in the ‘little brain’ involves Purkinje neurons in the Crus I and Crus II regions, a new study reveals.

In this edition, researchers sink a purported link between cerebellar volume and autism and buoy a theory about measuring social behaviors.

Animals with different autism-linked mutations share disruptions to the mTOR signaling pathway, pointing to a potential molecular mechanism for the atypical cerebellar development seen in some autistic people.

A new study is the first to link social, repetitive and motor behaviors to mutations in BMAL1, which regulates the body’s circadian rhythms.

The drug suppresses an overactive signaling pathway implicated in tuberous sclerosis complex.

Some genomic areas that help determine cerebellar size are associated with autism, schizophrenia and bipolar disorder, according to a new study. But heritable variants across the genome that also influence cerebellar size are not.
