Glut1 DS is a rare genetic disease.

Glucose transporter type-1 deficiency syndrome (Glut1 DS) is a rare disease that was first discovered in 1991 and is thought to affect between 3000 and 7000 people in the United States. For most, it is caused by mutations in the SLC2A1 gene.1,2

Glut1 DS In Focus is devoted to the education and awareness of Glut1 DS for patients, caregivers, and health care providers, as well as advancing research to treat this disease.
