Molecular mechanisms: FOXP2 leads to new autism gene

by  /  24 January 2014

FOXP2, a language gene that is linked to autism, may regulate active connections between neurons by controlling the levels of a protein called SRPX2, according to a study published 22 November in Science.

Molecular mechanisms: Maternal infection modifies histones

by  /  7 May 2013

Infection during pregnancy may alter the chemical tags that are added to histones, proteins that form a spool for DNA, according to a study published 9 February in Brain, Behavior and Immunity. Drugs that target these tags may treat neuropsychiatric disorders, the researchers say.

Stem cells reveal genes that have parental bias

by  /  31 October 2012

Researchers have used stem cells to identify 801 neuronal genes that are preferentially expressed from either the maternal or paternal chromosome, according to a study published 30 August in PLoS One. Of these genes, 26 are linked to autism and 48 to schizophrenia.

Genetics: Language gene may regulate autism, schizophrenia

by  /  11 April 2012

FOXP2, a protein linked to language development that regulates the expression of some autism-associated genes, also dampens expression of DISC1, mutations in which have been linked to both schizophrenia and autism. The results were published 20 March in Human Molecular Genetics.
