The Human Genome Project gave scientists an incredible roadmap of the thousands of genes used to construct the human body. However, many individuals harbor DNA that differs markedly from the standard reference sequence produced by that initiative, and these variations can have profound implications for a person’s health. A recent study led by IRP scientists has uncovered yet another of these genetic variants, a rare mutation that causes the eye disease retinitis pigmentosa.

For over a decade, my family shared our home with a short, fat beagle named Kayla Sue. She had big floppy ears, a tail as straight as an exclamation point, and a coat of fur that was a patchwork of white, brown, and black splotches. Her love of chasing small animals was matched only by her enthusiasm for eating, napping, and belly rubs. One of my best friends growing up, on the other hand, had a mean-spirited Dachshund named Rocky who would not let anyone outside his family touch his long, brown, sausage-shaped body. Meanwhile, one of my brother’s close childhood friends had two humongous, overly-friendly, black-and-brown German shepherds that would immediately bowl you over when you walked through the front door.
It doesn’t take a particularly sharp observer to notice that, despite being the same species, the more than 300 breeds of dog have remarkably different physical and behavioral traits. But what remains less clear even today are the specific biological roots that produce these widely varying attributes. And, perhaps more importantly, scientists seek to understand how learning about that immense diversity might help us improve the health of our canine companions – and ourselves.

In a new study of families affected by Attention Deficit Hyperactivity Disorder (ADHD), National Institutes of Health (NIH) Intramural researchers have identified different connections in the brain that children may inherit from their parents and are linked to the disorder.

Annaleise Knight is an active, outgoing six-year-old. In her hometown of Grayslake, Illinois, she loves riding her bike, swimming, taking ballet and tap lessons, and playing outside on the swings and trampoline with her three siblings, Nicholas, 16, Braden, 7, and Catherine, 4. Although Annaleise has an exuberant personality, she did not always have the energy and strength to do her favorite activities.
