Genome structure could be key factor in some forms of autism
Variants in DNA stretches that do not code for proteins may alter the genome’s 3D architecture, influencing the expression of distant genes linked to autism.

‘Polygenic risk scores’ for autism, explained
These scores — composite measures of a person’s autism-linked common genetic variants — cannot predict an autism diagnosis but could help researchers better understand the condition’s underlying biology.

Brain signatures of rare variants hint at cardiovascular risk
People whose brains look like those of people who carry autism-linked copy number variants also share markers of heart health.

Going on Trial: Orphan drugs; CBD; bumetanide
This month’s newsletter takes a close look at the orphan drug program in the United States, several cannabis-based therapies and a secondary analysis of bumetanide, among other new developments in autism-related drug trials.
Autism’s genetic heterogeneity evident in brain connectivity patterns
The results highlight the importance of subgrouping study participants based on their underlying genetics, the researchers say.

Chromosome 22 mutations leave telltale marks on brain development in autistic people
Many brain regions develop differently between people with 22q11.2 duplications and deletions, and those trajectories also vary with a person’s diagnosis.

Deletions on chromosome 22 have ripple effects across genome
Deletion of the 22q11.2 chromosomal region alters the expression of numerous autism- and schizophrenia-linked genes, most of which are not contained within the deleted region, a new study suggests.

Myelin loss may explain how autism-linked DNA deletion affects cognition
Deleting a copy of the gene TBX1 depletes the fatty myelin insulation that surrounds neurons and reduces cognitive speed in mice.

Copy number variations linked to autism have diverse but overlapping effects
People with mutations in distant chromosomal regions often share a range of autism traits, even if they do not meet the diagnostic threshold for autism.

Some minimally verbal autistic people show signs of written-language familiarity, study suggests
But researchers not involved in the work worry the findings could be used to support discredited facilitated-communication techniques.

Cocaine, morphine commandeer neurons normally activated by food, water in mice
Confirming a long-held hypothesis, repeated exposure to the drugs alters neurons in the nucleus accumbens, the brain’s reward center, and curbs an animal’s urge for sustenance.
