Researchers at King’s College Hospital, led by Professor Christopher Shaw, have embarked on the first gene therapy clinical trial for patients affected by a specific genetic form of ALS, the most common type of MND.

ALS is a progressive disease in which the nerves controlling muscle movement, known as motor neurons, degenerate resulting in muscle wasting and weakness. In about 10% of people the cause is a mutation in the C9orf72 gene. This mutation results in the formation of toxic products which are harmful to motor neurons. People with the mutation typically develop symptoms in their 50s, starting with speech and swallowing problems, followed by weakness of the arms, legs and breathing. It is also linked to problems with language and behaviour and is the most common genetic cause of frontotemporal dementia.Read More »
