Muscular dystrophy and related conditions cause muscles to waste and weaken. More than 70,000 people in the UK are affected

Fibre-type disproportion

Congenital fibre type disproportion (CFTD) is so named because of the characteristic appearance of muscle fibres under a microscope. Muscle tissue has two different types of fibre, type 1 and type 2. In muscle of people affected by CFTD, type 1 fibres are smaller than type 2 fibres, and there are often more type 1 fibres than type 2 fibres. This results in generalised muscle weakness. Progression of CFTD is highly variable and is often determined by genetic background.
