Researchers scanned genomes of 366 children with ADHD and compared them with 1,047 unrelated, ethnically matched control subjects. They reported full results in The Lancet. Rare copy number variants were almost twice as common in children with ADHD compared to the other children. Researchers commented to Reuters that there was a significant overlap between copy number variants found in ADHD and elements of the genome linked to autism and schizophrenia, specifically in a region on chromosome 16. *This blog post was originally published at AC...

The idea is that by having that information, you may be able to be more aware of potential health problems down the road. Or even stave them off before they become a problem by changing your behaviors, diet, and exercise regimen. Companies like 23andme and Navigenics provide genetic DNA testing reports that purportedly tell you your risk factors for getting not only certain medical conditions, but also mental disorders, like bipolar or attention deficit disorder. This may work fine for some very well-defined health issues, like heart disease (although a recent government investigation into these companies’ abilities to provide even this info...

Hers was an extremely rare genetic syndrome that baffled and fascinated the public since she was first exhibited by her husband. Pastrana has a genetic syndrome known as hypertrichosis terminalis where straight coarse hair covered her entire face and body, and her teeth and gums were irregular. "Bearded Lady" Julia Pastrana has rare genetic condition. Image: Public Domain New research released Thursday uncovered the exact genetic mutation responsible for  conditions similar to Pastrana’s.

Send me your post about genes and/or gene-related diseases and I’ll include it in a round-up this Saturday, March 24. Be on the lookout for some magical genetic moments. This morning, Genie is wondering how spontaneous deletions and duplications of DNA, aka copy number variation, scattered throughout the genome could be involved in autism spectrum disorders. Maybe they’re the result of some other injury that led to both autism and the mutations? Maybe it’s selection bias? The people in the study with autism must differ in other ways from healthy controls. Were all known and unknown factors controlled for? Genie reserves judgment until she knows more about what the biological importance of these hundr...
