THE UNDIAGNOSED DISEASES NETWORK
The National Human Genome Research Institute’s Undiagnosed Diseases Network (UDN) just announced the UDN Gateway. This online application portal will guide patients to a growing national network of clinical sites, including six new ones and two genome sequencing centers. The Gateway replaces paper-based application to specific clinical centers for the few coveted slots. (more…)

The first wave of targeted drug approvals were for cancers associated with specific mutations. Herceptin (traztuzumab) led the way, approved in 1998. It’s a monoclonal antibody deployed against the HER2/neu receptor that is overabundant in some aggressive and early-onset breast cancers. Robert Bazell’s excellent book Her 2 tells the tale.
In 2001 came the blockbuster Gleevec (imatinib), a small molecule tyrosine kinase inhibitor that intercepts signals to divide. Erin Zammett’s My So-Called Normal Life with Cancer relates that story. A very young editor at Glamour magazine when a routine check-up revealed chronic myelogenous leukemia, Erin’s recovery was one of the first of thousands thanks to this now famous drug. (more…)

PLOS Biology, "Chloe’s Law: A Powerful Legislative Movement Challenging a Core Ethical Norm of Genetic Testing." The concise and compelling article considers legislation to mandate that genetic counselors talk to their patients more about positive aspects of having a child with trisomy 21 Down syndrome.

“Alternative Splice in Alternative Lice,” provides a compelling example of maximizing genome information – adaptation of the louse Pediculus humanus to the new habitat created when our ancestors invented clothing.A terrific article recently published in Molecular Biology and Evolution,
HEAD VS BODY LICE
Many parents encounter head lice when their children are sent home from school with instructions to get rid of the horrible rice-krispie-like eggs (“nits”) clinging to their scalp hairs. A good washing won’t do it. Medication and clunky combs do very little alone. The sooner the poor parent realizes that meticulous nit-picking is the only solution, the sooner the nightmare ends.
But consider the louse’s point of view.
Lice live on us so that they can drink our blood, with a little help from bacteria that provide the B vitamins needed to extract maximal nutrients from their meals. Head lice lay their eggs on our hair shafts, gluing them in place. These are the much more common variety. They don’t carry disease, and are mostly an annoyance. (more…)

For years I wrapped my tangles around soup cans and around my head, squished it under irons, and subjected it to stinky straighteners. I’d often succeed, only to venture outside and have the hated curls spring up and out anew.
Eleven-year-old Hannah Sames also relaxes her curls. In fact, the pale kinks were the first thing Hannah’s parents, Lori and Matt, noticed when she was born. “Their other daughters, Madison, five, and Reagan, two, had stick-straight hair, as do Lori and Matt. When the birthing goop had dried, Hannah’s curls were odder still, weirdly dull, like the ‘before’ photograph in an ad for a hair conditioner,” I wrote in my gene therapy book. A more recent story about a little girl with curly hair but straight-haired siblings and parents in the Times of India is remarkably similar. (more…)

A few weeks ago, a study published in Investigative Ophthalmology and Visual Science caught my attention. Researchers at the Translational Genomics Research Institute (TGen) in Phoenix used exome and genome sequencing to probe the origins of a condition I'd never heard of -- and the findings were surprising.

Bake sales and bike races, balls and raffles, exhausting and all-consuming. But these efforts pale when a performer or other famous rich person suddenly and explosively steps up to support such a disease, solely because someone they know has just been diagnosed. As if dozens of families haven’t already been trying to fund clinical trials for years. Last summer’s "ice bucket challenge" was the epitome of the power of viral social media, with the message about ALS lost in the excitement.
When celebrities suddenly care about rare diseases, I wonder what my friends in the rare disease community think. They’re happy, of course, at the attention, yet perhaps a bit unglued by the power of the famous – but maybe afraid to say so.
That happened recently for Batten disease, a devastating group of brain disorders that strike in childhood. One family isn’t afraid to speak out.
Two years ago my blog DNA Science gave a voice to Laura King Edwards, who has been running races in all 50 states in honor of her 16-year-old sister Taylor, who has Batten disease. Laura updated a year ago.
This year, she and her mother Sharon King share their thoughts about last week’s avalanche of concern for the disease that is taking Taylor away. (more…)

As a boy, Joe believed the neighborhood talk that his institutionalized mother was an alcoholic. He remembers his skeletal, writhing, grimacing and grunting mother as a monster, not as someone suffering from a neurological disease only trying to say “I love you” to her terrified son. (more…)
