Overview

Riboflavin transporter deficiency is a type of degenerative nerve disease generally characterized by sensorineural deafness, paralysis of the cranial nerves, and lower and upper motor neuon disease. It includes the formerly recognized disorders: Brown-Vialetto-Van Laere (BVVL) syndrome and Fazio-Londe syndrome, which is similar to BVVL syndrome but lacks deafness. Initial symptoms occur in infancy to early adulthood and progress with time. The rate of progression is different from person to person. Signs and symptoms may include vocal cord paralysis, drooping eyelids, facial weakness, slurred speech, difficulty swallowing, diminishing eye sight, neck and shoulder weakness, weakness in the arms and legs, gait problems, autonomic dysfunction, and difficulty breathing. It is caused by mutations in the SLC52A2 gene (riboflavin transporter deficiency neuronopathy, type 2) or mutations in the SLC52A3 gene (riboflavin transporter deficiency neuronopathy, type 3) and it is inherited in an autosomal recessive pattern. Treatment is made with high doses of riboflavin and is usually effective.[1]
