Genetics algorithm reveals mosaic mutations

by  /  10 July 2013

A new software tool detects chromosomal alterations present in only a subset of cells in the body. This method, described 31 May in BMC Genomics, may help reveal mosaicism’s contribution to neurological disorders.

Twin study finds epigenetic imprint of autism traits

by  /  16 May 2013

Epigenetics, or the chemical markings on DNA that affect gene expression, plays a role in some cases of autism, according to a study of 50 identical twins published 23 April in Molecular Psychiatry.

Twin study suggests girls are protected from autism risk

by  /  28 February 2013

A comparison of autism-like behaviors in nearly 10,000 pairs of fraternal twins suggests that girls are somehow protected from the disorder. The findings, published 19 February in the Proceedings of the National Academy of Sciences, may partly explain why autism is four times more common in boys than girls.

Genetics: Autism risk higher in full than in half siblings

by  /  23 March 2012

Full siblings are twice as likely as half siblings to share a diagnosis of autism, according to a short report published 28 February in Molecular Psychiatry. The results suggest that genetic factors play an important role in the risk of developing autism, the researchers say.

Genetics: Different mutations lead to autism in same family

by  /  24 February 2012

Twin brothers who have autism carry a non-inherited duplication that overlaps with 16p11.2, a chromosomal region that has been associated with autism. Their brother, who also has autism, has a nearby deletion within 16p11.2, according to a study published 11 January in the European Journal of Human Genetics.
