Overview

POMGNT2-related limb-girdle muscular dystrophy R24 (also called LGMD R24 or POMGNT2-related muscular dystrophy) is a rare inherited muscle disease caused by changes in the POMGNT2 gene. This gene provides instructions for making an enzyme that helps attach sugar molecules to a protein called alpha-dystroglycan. Alpha-dystroglycan acts like a glue that holds muscle cells together and connects them to the surrounding tissue. When POMGNT2 does not work properly, this connection is weakened, and muscle fibers become damaged over time. The disease mainly affects the muscles closest to the center of the body — the hips, thighs, and shoulders — which is why it is called 'limb-girdle' muscular dystrophy. People with this condition typically experience progressive muscle weakness and wasting, making it harder to walk, climb stairs, or lift their arms. Some individuals may also have involvement of the heart muscle or breathing muscles as the disease progresses. There is currently no cure for POMGNT2-related LGMD R24. Treatment focuses on managing symptoms, maintaining function, and improving quality of life. This includes physical therapy, assistive devices, respiratory support if needed, and regular monitoring of the heart. A team of specialists works together to help people with this condition live as fully as possible.
