The Congenital Merosin-Deficient Muscular Dystrophy is an inherited disease, very rare and serious, which is classified among Muscular Dystrophy diseases. Their main feature is the muscular weakness since the childhood, generally before being 2 years old.
The LAMA2-CMD constitute between 30-40% of the congenital muscular dystrophies with a frequency of 1/30.000.
Children with a total deficiency of merosin present hypotonia (decreased muscle strength and floppiness), progressive joint contractures, delayed or limited motor development and breathing and feeding problems since very young. They can also develop scoliosis and rigid spinal column. In some cases they have heart abnormalities
People with a partial deficiency of merosin, can last more time to present these features (end of the childhood, beginning of the adult age) and symptoms are not so clear. In both cases, brain development is normal.
