Overview

Congenital muscular dystrophy-respiratory failure-skin abnormalities-joint hyperlaxity syndrome is a very rare inherited muscle disease that is present from birth or becomes apparent in early infancy. It belongs to a group of conditions called congenital muscular dystrophies (CMDs), which cause muscle weakness starting very early in life. This condition is sometimes referred to by its Orphanet code ORPHA:486815 and is caused by changes (mutations) in the LAMA2 gene, though some cases may involve other related genes. The disease affects several body systems at once. The muscles are weak from birth, making it hard for babies to move, feed, and breathe normally. The breathing muscles can become so weak that a breathing machine (ventilator) may be needed. The skin may look unusual, with changes in texture or structure. The joints are often very loose and flexible (hyperlaxity), which can lead to dislocations and posture problems. There is currently no cure for this condition. Treatment focuses on managing symptoms, supporting breathing, protecting the joints, and improving quality of life. A team of specialists — including neurologists, pulmonologists, and physiotherapists — work together to help patients and families. Early diagnosis and proactive care can make a meaningful difference in day-to-day life.
