Researchers at Adelaide’s Women’s & Children’s Hospital and the University of Adelaide, Australia, have found that a mutant gene causes epilepsy and intellectual disabilities specific to women. As noted in Science Daily, the study links a “large family of genes known as protocadherins with a condition known as ‘epilepsy and mental retardation limited to females’ […]

Disruptions in the gene contactin 4—which helps the brain make connections—can stop the gene from working properly, and prevent from the brain from making networks, according to researchers in the Journal of Medical Genetics. The leader of the study, Dr. Eli Hatchwell of Stony Brook University Medical Center in New York, suggests that these disruptions—in […]

There is no prenatal genetic test for autism; there has been speculation that, as research into the genetics of autism develops, such a test might be created. Back in June of 2006, a team of doctors at University College Hospital in London—in view of the fact that autism is diagnosed in boys at a much […]

A team of researchers from Newcastle University has created an embryo from three separate parents by using DNA from one man and two women. The researchers hope that, by using this technique, women with diseases of the mitocondria (”mini organelles that are found within individual cells”) do not pass on diseases such as fatal liver […]
