RNA binds to fragile X gene, shutting it down
Misplaced pieces of RNA bind and disable the gene responsible for fragile X syndrome, leading to the disorder, according to a study published 28 February in Science.
Attention deficit in mothers raises children’s autism risk
Children of women who have attention deficit hyperactivity disorder are at increased risk for autism and attention deficit, according to a study published 21 January in the Journal of Child Psychology and Psychiatry. This suggests the two diseases have common risk factors.

Spontaneous and rare mutations are key in schizophrenia
Spontaneous and rare mutations, particularly in genes related to networks that regulate neuronal connections, contribute a small but significant proportion of the risk for schizophrenia, report two large studies published online 22 January in Nature.

Duplication of chromosome 22 region thwarts schizophrenia
Carrying a duplication of the 22q11.2 chromosomal region may protect against schizophrenia, suggests a study published 12 November in Molecular Psychiatry. This is the first evidence of a genetic region that lowers the risk of a disorder rather than increases it.

Genetics: SHANK3 duplication leads to hyperactivity in mice
Mice with a duplication of SHANK3, a gene with strong links to autism, are hyperactive and manic, reports a study published 7 November in Nature.

Ketamine targets lateral habenula, setting off cascade of antidepressant effects
The drug’s affinity for overactive cells in the “anti-reward” region may help explain its rapid and long-lasting results.
