Cardiac Care in MMD: Lack of Symptoms May Mask Deadly Problems

In 2006, Ron Hayes was a 54-year-old executive at Procter & Gamble in Cincinnati when he began noticing some weakness in his hands. "I was trying to clean my glasses," he remembers, "and my thumb couldn’t push the spray." A visit to a hand surgeon resulted in a referral to a neurologist and ultimately to a diagnosis of adult-onset  MMD1. A DNA test of Hayes’ blood cells revealed 131 CTG repeats, consistent with the mild end of the MMD1 spectrum. In fact, Hayes had been active in sports in high school and had a football scholarship in college.

Excessive Daytime Sleepiness Can Be 'Debilitating' in MMD1 and MMD2

Thirty-two-year-old Doug Hayes has struggled with some of the cognitive and social features of  type 1 myotonic dystrophy (MMD1  or  DM1)  most of his life. But there’s something else that’s contributed to his difficulties with jobs and schooling: daytime sleepiness. Doug recently had a job scanning documents, his father says, but his daytime sleepiness interfered.

In Focus: Myotonic Muscular Dystrophy

As far back as Carla Licon can remember, her mother had difficulty opening jars and walking long distances. Licon’s mother wore ankle braces, and she also had an unusual symptom known as "myotonia," the inability to relax muscles, such as a clenched hand, at will.Licon, who is 31 and lives in Victoria, Texas, thinks these symptoms started when her mother was in her 20s. Later, her mother’s respiratory muscles weakened, leading to pneumonia, respiratory failure and her death at the age of 52.

SMA Disease Course May Be Affected by ZPR1

Adequate levels of  zinc finger protein 1 (ZPR1)  appear to be a "protective" modifier of  spinal muscular atrophy (SMA), an MDA-supported team of scientists has reported.Modifiers influence disease onset and severity by changing various biological pathways.The identification of ZPR1 as a modifier reveals a potential target for therapy development and also sheds light on the mechanisms that drive SMA.

SMA Research Briefs: Antisense and Fasudil

Below are highlights of two studies in  spinal muscular atrophy (SMA), a disease in which the nerve cells that control muscles (motor neurons) in the spinal cord die, causing progressive weakness in the voluntary muscles.The underlying cause of SMA is a deficiency of  SMN  protein, which cells normally produce using genetic instructions carried by two nearly identical genes in the body:  SMN1  and  SMN2. (SMN stands for "survival of motor neurons".) The deficiency occurs when flaws in the SMN1 gene render its genetic instructions unusable. Some — but not enough — SMN protein is produced from the instructions carried by the SMN2 gene.

Not Just Horsing Around

It’s good to be back in the saddle.I thought my horseback-riding days were over due to the progression of  Friedreich’s ataxia, until I found  Therapeutic Riding of Tucson (TROT)  in Arizona.I’m finishing up my second 12-week session at TROT, and I’ve noticed that — even with having a neuromuscular disease at age 33 — I’ve experienced many benefits from therapeutic riding.

Why Does It Take So Long To Go from Mouse to Man?

John Porter from the National Institutes of Health likes to start talks by noting, “It’s a great time to be a mouse with a neuromuscular disease.” Exciting research results are regularly reported, where a treatment appears to cure one neuromuscular disease or another in a mouse — yet there are few treatments available today for  people  with any of these diseases, and only a few treatments in human clinical trials. Why does it take so long?
