Kennedy’s Disease: focus on muscle damage reveals key biomarker

Findings from the largest biomarker study of people with Kennedy’s Disease, published in the journal Neurology, found a predictive biomarker to help in differential diagnosis and tracking clinical progression. Led by Dr Pietro Fratta from University College London, the research team highlighted the importance of markers of muscle mass rather than neuronal damage in Kennedy’s Disease, differentiating it from the slightly more common motor neurone disease (MND).

Kennedy’s Disease, also known as Spinal and Bulbar Muscular Atrophy (SBMA), is a rare genetic condition that leads to progressive weakening and wasting of muscles, particularly affecting the limbs and bulbar region. Caused by a mistake on the AR (androgen receptor) gene (positioned on the X chromosome), this condition mainly affects males, with a 50% chance of receiving the affected gene from their mothers (women can only be carriers of the genetic mistake without developing the disease).

Raising the profile of Kennedy’s disease

Did you know the MND Association also supports people who have Kennedy’s disease?

In May a new clinic specialising in Kennedy’s disease opened in London at the National Hospital for Neurology and Neurosurgery.

To mark this big step in helping support and treat people with Kennedy’s disease, Katy Styles who campaigns on behalf of the Association, and whose husband Mark has Kennedy’s disease, thought it would be a great opportunity to raise awareness of this rare condition.

There is very low awareness of this disease amongst neurologists, healthcare professionals, the general public and within the Association itself. We do all we can to explain to everybody what Kennedy’s disease is and what it’s like to live with.

Due to the rarity of Kennedy’s disease you can feel very much alone. It is so great to be part of the MND family and the Association is key to this by making us feel part of a wider community.”

What is Kennedy’s disease?

Kennedy’s disease is a condition similar to motor neurone disease (MND) which affects motor neurones. It is sometimes called spinal and bulbar muscular atrophy (SBMA).Read More »
