Primary lateral sclerosis juvenile


Type of disease: Rare conditions

Juvenile primary lateral sclerosis is a rare disorder characterized by progressive weakness and stiffness of muscles in the arms, legs, and face. This disorder damages motor neurons, which are specialized nerve cells in the brain and spinal cord that control muscle movement. Symptoms begin in early childhood and progress over a period of 15 to 20 years. Juvenile primary lateral sclerosis is caused by mutations in the ALS2 gene. It is inherited in an autosomal recessive pattern. Source: Genetic and Rare Diseases Information Center (GARD), supported by ORDR-NCATS and NHGRI.
