Thousand genes differences contribute to autism risk

Changes in scores of genes contribute to autism risk — Newfound genetic differences provide many hints at causes – Small differences in as many as a thousand genes contribute to risk for autism or autism spectrum disorder (ASD). This new study examined data on several types of rare, genetic differences in more than 14,000 DNA samples from parents, affected children, and unrelated individuals.

2 studies: The first finds twins born after fertility treatment have a higher risk of problems. A second study study finds reassuring evidence on the outcome of children born after embryo freezing. – Twins born as a result of assisted reproductive technology (ART) are more likely to be admitted to neonatal intensive care and to be hospitalised in their first three years of life than spontaneously conceived twins, according to new research in Europe’s leading reproductive medicine journal Human Reproduction.
