It is part of a group of genetic conditions called congenital muscular dystrophies, which cause weak muscle tone (hypotonia) and muscle wasting (atrophy) beginning very early in life.  In people with L-CMD, muscle weakness becomes apparent in infancy or early childhood and can worsen quickly. The most severely affected infants develop few motor skills, and they are never able to hold up their heads, roll over, or sit. Less severely affected children may learn to sit, stand, and walk before muscle weakness becomes apparent. First the neck muscles weaken, causing the head to fall forward (dropped-head syndrome). As other skeletal muscles become weaker, these children may ultimately lose the ability to sit, stand, and walk unassisted.  Other features of L-CMD often include spinal rigidity and abnormal curvature of the spine (scoliosis and lordosis); joint deformities (contractures) that restrict movement, particularly in the hips and legs; and an inward-turning foot. People with L-CMD also have an increased risk of heart rhythm abnormalities (arrhythmias).  Over time, muscle weakness causes most infants and children with L-CMD to have trouble eating and breathing. The breathing problems result from restrictive respiratory insufficiency, which occurs when muscles in the chest are weakened and the ribcage becomes increasingly rigid. This problem can be life-threatening, and many affected children require support with a machine to help them breathe (mechanical ventilation).","Curated_USA_Estimate_Source__c":null,"Curated_USA_Estimate__c":"1,000","Age_at_Onset_Snippet_Text__c":"as a Newborn and as an Infant","SourceID__c":"ORPHA:157973","Deprecated__c":"No","Disease_Concept_Type__c":"Rare Disease Entity","MONDO_ID__c":"MONDO:0013178","ORPHANET_ID__c":"ORPHA:157973","Replaced_By_ID__c":null,"Display_Spanish_Disease_Name__c":"Distrofia muscular congénita por una mutación en el gen lmna","Spanish_Description_Source__c":"ORPHA:157973","Spanish_Description__c":"Es una distrofia muscular congénita poco frecuente caracterizada por una hipotonía axial prominente, debilidad muscular predominantemente proximal en las extremidades superiores/ distal en las extremidades inferiores, contracturas articulares (inicialmente distales, posteriormente proximales), rigidez de la columna vertebral e insuficiencia respiratoria progresiva, en presencia de una elevación moderada de creatinquinasa sérica.
