Molecular mechanisms: Autism protein connects neurons

by  /  28 November 2012

An autism-linked protein called CASPR2 promotes the development of dendrites, the bushy structures atop neurons that receive signals from other neurons, according to a study published 30 October in Proceedings of the National Academy of Sciences. Lowering CASPR2 levels leads to sparse dendrites and few synapses, the junctions between neurons.

Genetics: Chromosomal syndrome narrowed to single gene

by  /  11 September 2012

Symptoms associated with a deletion of the 15q13.3 chromosomal region could result from the loss of a single gene, CHRNA7, according to a study published 9 July in Clinical Genetics.
